Investment and Its Importance

Investment is important from many points of view. Before doing investment, it is essential to understand what is investment and its importance?

“Investment is an act of investing money to earn the profit. It is the first step towards the future security of your money.”

Need of Investment

The investment can help you in the future if invested wisely and properly. As per human nature, we plan for a few days or think to plan for investment, but do not put the plan into action. Every individual must plan for investment and keep aside some amount of money for the future. No doubt, the future is uncertain and it is required to invest smartly with some certain plan of actions that can avoid financial crisis at point of time. It can help you to bring a bright and secure future. It not only gives you secure future, but also controls your spending pattern.

Important Factors of Investments

Planning for Financial investment – Planning plays a pivotal role in all fields. For the financial investment, one must have a pertinent plan by taking all rise and fall situations of the market. You should have a good knowledge of investment before planning for financial investment. Keen observation and focused approach are the basic needs for successful financial investment.

Invest according to your Needs and Capability- The purpose behind the investment should be clear by which you can fulfil your needs from the investment. In investment, financial ability is also a component that can bring you satisfaction and whatever results you want. You can start investment from a small amount as per your capability. You should care about your income and stability to choose the best plan for you.

Explore the market for available investment options – The investment market is full of opportunities, you can explore the market by applying proper approach. You can take help from financial planners, managers who have thorough knowledge about investment in the market. Explore the possibility of investment markets and touch the sublime height of success by the sensible investment decisions.

By taking help from an experienced, proficient financial planner and traders can also give you confidence to do well in the field of investment. Now the question strikes the mind that what are the types of investments?

Types of Investments

Mutual Funds- Basically the mutual fund is a managed investment fund in which money is pulled from the investors to buy the securities.

Commodity Market- In India, it is a popular place of traders to invest their money. The commodity market comprises of MCX (Multi Commodity Exchange) and NCDEX (National Commodity and Derivatives Exchange) both. In Multi Commodity Exchange market, you can invest in crude oil, precious metals as gold, silver and base metals as copper, aluminium, nickel, zinc and many more. While in National Commodity and Derivatives Exchange market, you can invest in all agricultural commodities as guar, soya bean, cotton, sugar cane and many more.

Stock Market- It is the place where various people trade globally and earn the maximum return on investment. However, it is essential to know the bull and bear of the stock market for investing in it. The Stock market for investment also includes the equity market and nifty market. You can invest in equities and nifty market and get good amount profit by focused approach and keen analysis of market trend.

Bonds – It is the best ways to gain interest on your principal amount. The interest and period of time depends on the agreement. In this, a holder lends a particular amount to the issuer (borrower) for a fixed period of time. At this time, you will get the interest from the borrower and after completing that fixed period of time borrower will return back your money. A long term tool for financial investment.

Fixed Deposits – The Fixed Deposit (FD) service is provided by various banks that offers investors a higher rate of interest on their deposits as compared to a regular savings account. Fixed deposits have the maturity date to gain the return on investment.

Real Estate- One can also invest in the real estate and deal with the residential and commercial property. This is also a trending way to earn a good return on investment.

There are various financial planners, financial managers, trading tips provider who can give you numerous options for investment in the market. But it is essential to choose the options wisely.

HIV Education in the Schools Across America

AIDS has devastated the lives of many citizens in the United States. The Centers for Disease Control and Prevention (CDC) indicates that the number of AIDS infections among young Americans between the ages of 13 to 25 rose nearly 20 percent, and approximately 50 percent of new infections are among individuals who are younger than 25 years of age. Therefore, finding better methods to communicate the risk of AIDS transmission are greatly needed to protect our young people and preserve the next generation.

Young people in the United States are at a persistent risk of HIV infection. This risk is especially notable for youth of minority races and ethnicities. Continued HIV prevention outreach and education efforts, including programs on abstinence and delaying initiation of sexual relations, are required as new generations replace the older generations that benefited from earlier prevention strategies.

I believe that there should be more HIV and AIDS education in the school systems across America. I feel that this is an area of education that we could improve to protect and preserve our next generation. There are two reasons that I feel this way. My first reason is to prevent a student from being discriminated against, and the second reason is giving education to the students on preventing the spread of this disease.

My first reason for believing there should be more education about HIV and AIDS in the school system is the way I was treated when I was diagnosed with HIV. I was diagnosed with HIV at 14 years old and due to the lack of education to the teaching staff in the earlier years; I wasn’t permitted to attend class in a regular school setting. Instead I was forced to be home schooled by the board of education, (homebound program) in which I wasn’t taught all the subjects as a regular student would be. I wasn’t taught mathematics at a high school level so when I decided to attend college I had a lot of difficulties in the area of mathematics. On the other hand, English was drilled into my head like a nail, which I am grateful for. The reason for this was that my homebound teacher was an English Professor before she started teaching in the homebound program.

Even though I wasn’t taught as well as those students attending classes in a regular school setting, I have become an excellent student in college despite my difficulties in math. I do believe, however, that the school system has gotten better. I haven’t had any problems with discrimination while attending college. That, at least, is a good thing!

Secondly, I feel that if there had been more education on the prevention and spread of this disease, I might not have contracted it. Had I known about the risks of this disease, I may not be infected today. Even though I contracted HIV through a blood transfusion, maybe if I had been more educated on the ways it is transmitted, I could have somehow prevented myself from becoming infected.

Therefore, I believe that there should be more education for students. The students are our next generation. They should be educated about the risks of HIV infection. I feel it should be a requirement for the schools to inform students about the dangers of the disease as well as the myths of being around someone who is infected.

Even now I feel I have to be careful when I disclose my diagnosis, which prevents me from making friends for fear of being rejected. I feel that if there were more education, I could feel more comfortable talking about my situation of having this disease. Ultimately, I wouldn’t be afraid of causing a panic among my peers. Finally, I believe with more education it would prevent the rise of students becoming infected with this disease. I believe that it is our obligation to protect the next generation.

The Transformative Power of Sacred Art-Making

When I began teaching Western women the sacred art of Tibetan appliqué in 2008, I thought I was just teaching stitching technique. My students quickly set me straight. It turns out I had seriously underestimated the power of tradition and   transmission . Through teaching, I discovered the transformative effect of the sacred textile art I’d been making for 20 years.

I had lived in northern India for nine years and learned to make silk thangkas in apprenticeship to Tibetan master craftsmen.

A thangka is rollable wall hanging, a scroll, depicting a sacred image or spiritual teacher. Most thangkas are painted on canvas and framed in brocade, but I studied a rarer type of thangka in which the images are built from hundreds of pieces of silk, outlined in hand-wrapped horsehair, assembled in an intricate patchwork.

Six days a week for four years, I sat alongside young Tibetans in a sewing workshop just outside the Dalai Lama’s temple. The environment was infused with dharma. Sounds of teaching and practice echoed from every window and courtyard. I attended Buddhist philosophy classes in the morning with learned Tibetan scholars (geshe) and then trudged up the steep hill to the workshop where I stitched thangkas all afternoon.

I had absorbed the dharma this community breathed, and it came out through my fingers into the thangkas I stitched. But I was no dharma teacher, and only an inconsistent meditator. I told prospective students that I would teach them stitching techniques, made sacred only by association. They should not expect spiritual illumination from me. They must seek that elsewhere, I thought.

Little did I know, each line and stitch of this artwork carries the light of the buddhas and of generations of artists and practitioners. You can’t escape the deeper lessons woven into the fabric of this lineage.

I was living in Italy, married and making thangkas on commission, when an American woman in France contacted me and sparked the creation of the Stitching Buddhas Virtual Apprentice Program. Louise had returned to France after many years of following her husband’s job from country to country while raising young children. Now, she was seeking an occupation, something meaningful to do with her energies.

Louise had been trained as a costume designer and was a practicing Buddhist. When she saw her first silk thangka on the internet, it struck her as a natural coupling of her creative background with her spiritual practice. I had the same feeling sixteen years earlier when I walked into a Tibetan appliqué studio in India. Could I now offer this gift to others?

Working with needle and thread re-awakens our tactile intelligence. Eyes and ears are not our only receptors for learning. The rational mind is not our only mode of understanding. And the voice is surely not our only instrument for communicating. We perceive, learn, and communicate through our fingers as well. But in the 21st century, our range of manual engagement has been reduced to tapping smooth keys and swiping touch-screens.

People who knit or quilt or work on a potter’s wheel have experienced the mindful quality that can arise in slow, deliberate movement and tactile sensation. Doing something by hand slows down the busyness of life – if only momentarily.

Not only that, but the thread becomes a metaphor for your life. You see how things get tangled when you don’t pay attention. You see where perfectionism trips you up, where you are afraid to move forward and how, sometimes, the more effort you exert the worse things get. Sometimes gentleness and a relaxed approach are needed. These patterns become evident in the stitching, and awareness filters into other activities.

The Tibetan appliqué tradition flows from an ancient spiritual lineage of artists, teachers and practitioners who have created and used its images in their practice. When we stitch, we receive their  transmission  through our fingers.

People often ask if I meditate while I stitch. I say this stitching IS meditation.

Literally, the Tibetan word for meditation (gom) means to familiarize. Through meditation, we familiarize ourselves with desirable mind states – expansive, loving, generous, imperturbable mind states – in an effort to make them habitual.

When we stitch a thangka or even a lotus flower, we are in the presence of enlightenment. We familiarize ourselves with enlightened beings, and therefore with the highest qualities of our own nature. The images in our hands symbolize the clearest, highest, best parts of ourselves and of humanity. Stitch by stitch, we allow these qualities to fill us.

Most of my students, the Stitching Buddhas, are women in the 50s and 60s. They are well educated. Many have worked in healing professions such as nursing, medicine, social work, and psychotherapy. Many are mothers of grown children. They come to the practice with an awareness of limited time. Some face diminishing eyesight or challenges to their manual dexterity. Some have no sewing experience at all. They’re not preparing for a career in thangka-making. They are seeking to live their life meaningfully and happily, and to leave something beautiful in their wake.

Buddhism encourages us to recognize our good fortune and to use this precious human life well. Human rebirth is rare and hard to come by. With gratitude in her heart, each woman-buddha stitches her response to Mary Oliver’s sumptuous question: “Tell me, what is it you plan to do with your one wild and precious life?”

Motorcycle Automatic Transmission – The Top 3

Motorcycle enthusiasts love a wild goose chase such as the famously beloved, Bigfoot. Many motorcyclists fail to believe that there is actual automatic transmission motorcycles that exist. This is not true because the knowledge isn’t out there. This is actually true because of there just aren’t to many readily available. The top three automatic transmission motorcycles really exist and the proof is found by reading on.

3. The Honda DN-01

The Honda DN-01 was introduced in 2005 as a cruiser motorcycle. This is one of the first of very few automatic transmission motorcycles ever released. The bike didn’t actually make it on showroom floors until 2008-2009. This bike is so powerful to the consumer that it is still being offered in shops as of early 2011. Missing you chance to check out the Honda DN-01 is just wrong. The Honda DN-01 is just one of those bikes you can’t miss a chance to try out for yourself.

2. The Aprilia Mana 850

The Aprilia Mana is a newer automatic transmission motorcycle that was just released last year. This bike is fast and very powerful. The Aprilia Mana 850 is a sleek sports bike that offers highlights from leather to chrome and everything in between. There is nothing better than a quick bike with the backing of being an automatic transmission motorcycle. The Aprilia Mana 800 makes its way to this top three list for being a solid bike with an even nicer ride.

1. The Honda CB750

The Honda CB750 has had many models in its series between 1969-2003. The Honda CB750 automatic transmission models is better known as the Honda CB750 Hondamatic. This model is one of a kind that has a coil ignition start and a solid inline four stroke SOHC air cooled engine. The only downfall to this model was the fact that the gear changing was not automatic. Instead, each gear was chosen by a foot-controlled hydraulic valve. This bike only sold in the North American market but can now be found all over the world.

Learn How to Drive Online – Learn to Drive Easily

Learning to drive is not the easiest thing to do, especially if you are a young person. Whether you are young or a little older and trying to get your license, you need to be aware that it is possible to learn how to drive online.

The internet is a very powerful tool and just about anything can be learned on it very easily. Driving is no exception. While formal drivers education classes are certainly needed and highly recommended, there are resources online that can help you learn just as much or even more than you would from a regular in-person class.

The best product that I have ever come across to help people learn how to drive online is a video education course called Get Ready To Pass. I have done an in depth review of it and found it to be extremely effective.

The reason why I liked this product so much is because it gives the user all the tools that are needed to succeed and pass the road driving test the very first time. About half of people who attempt their road test fail on their first try. I know this because I was one of them!

I could have really used the resources given by this online drivers education website and helped myself be more prepared. It would have certainly been worth sparing the embarrassment I felt having to tell my friends that I could not drive good enough to pass.

In closing, it is totally possible to learn how to drive online if you want to. I recommend an online course that includes videos and has a solid customer base of people whom it has worked for. I know that I definitely could have used the help!

EDGE: A Stepping-stone Toward 3G Technologies in Pakistan

ABSTRACT

The business of wireless data is expected to grow in the region of 100-200 % per annum and the mobile communication industry agrees that wireless data services will form the foundation for future business. The enormous success of short messaging in many countries proves that people accept the benefits of non-voice services.

Enhanced Data Rate for Global Evolution (EDGE) is a technology that gives Global Systems for Mobile Communications (GSM) the capacity to handle services for the third generation of mobile telephony. It provides three times the data capacity of General packet Radio Service (GPRS). Using EDGE, operators can handle three times more subscribers than GPRS; triple their data rate per subscriber, or add extra capacity to their voice communications.

This article provides an overview of EDGE technology. In particular, starting from the introduction of this 2.5G technology I describe the core technical aspects and distinct features. I will provide a comparison with GPRS for data services and then a survey of the current state of this technology in Pakistan. I have also covered some benefits for operators and customers.

1. Introduction

The importance of wireless data and multimedia services both for business and end customers are increasing on an unparalleled scale. Enhanced Data Rates for GSM Evolution (EDGE) is a new radio interface solution and is based on an enhanced modulation. EDGE offers GSM network operators an evolution path to mobile data and multimedia services with a three fold increase of data throughput in the existing GSM spectrum. EDGE therefore provides an alternative for operators who do not have a Universal Mobile Telecommunication System (UMTS) license. Moreover it also represents a complement to UMTS for operators intending to first deploy UMTS only in densely populated areas, but who can also use EDGE to provide wide area coverage of future oriented 3G services. In the US market operators have chosen EDGE as the 3G solutions. [8].

We are presently experiencing the Wireless Application Protocol (WAP) as well as the higher   transmission  speeds of High Speed Circuit Switched Data (HSCSD), joined by the convenience of “always on-line” direct Internet connections with GPRS. [1]

EDGE, new radios interface technology with enhanced modulation, increases the HSCSD and GPRS data rates by up to three fold. EDGE modulation is going to increase the data throughput provided by the packet switched service even over 400 kbps per carrier. Similarly, the data rates of circuit switched data can be increased, or existing data rates can be achieved using fewer timeslots, saving capacity. Accordingly, these higher speed data services are referred to as EGPRS (Enhanced GPRS) and ECSD (Enhanced Circuit Switched Data).

EDGE, is a major improvement in GSM phase 2+. As a modification to existing GSM networks, EDGE does not require new network elements. [1]

In the US, for instance, EDGE is part of the IS-136 High Speed concept, which is one of the third generation Radio  Transmission  Technology (RTT) proposals from TR.45. EDGE is eventually going to be standardized which makes possible to achieve a global mobile radio system with many services characteristic to third generation systems.

2. Overview

The increased bit rates of EDGE put requirements on the GSM/GPRS network architecture. Figure. 1 illustrates the GSM/GPRS architecture, the shaded parts of which are discussed in this section. Other nodes and interfaces are not affected at all by EDGE introduction. An apparent bottleneck is the A-bis interface, which today supports up to 16 kb/s per traffic channel. With EDGE, the bit rate per traffic channel will approach 64 kb/s, which makes allocation of multiple A-bis slots to one traffic channel necessary. Alternative asynchronous transfer mode (ATM) or IP-based solutions to this problem can also be discusses.

One important fact is, however, that the 16 kb/s limit will be exceeded already by the introduction of two coding schemes (CS3 and CS4) in GPRS, which have a maximal bit rate per traffic channel of 22.8 kb/s. Consequently, the A-bis limitation problem is being solved outside the EDGE standardization, and it is therefore a GPRS related, not EDGE-related, modification. For GPRS-based packet data services, other nodes and interfaces are already capable of handling higher bit rates, and are thus not affected. For circuit-switched services, the A interface can handle 64 kb/s per user, which is not exceeded by EDGE circuit-switched bearers. [9]

2.1. Impact on GSM Network Planning

An important prerequisite, which to a large extent will determine the success of EDGE in GSM, is that a network operator be able to introduce EDGE gradually. For initial deployment, EDGE-capable transceivers will supplement standard GSM/GPRS transceivers in a subset of the existing cells where EDGE coverage is desired. Hence, an integrated mix of GSM, GPRS, and EDGE users will coexist in the same frequency band. To minimize effort and cost for the network operator, radio network planning (including cell planning, frequency setting of power and other cell parameters) must not require extensive modification.

2.1.1. Coverage Planning

One characteristic of non-transparent radio link protocols that include automatic repeat request (ARQ), is that low radio link quality only results in a lower bit rate for the user. Hence, low SIR for a user does not result in a dropped call, as for speech, but in a temporary decrease of user bit rate. For transparent bearers, which typically offer a constant bit rate, link quality control must be extended to incorporate resource allocation, in the sense that the number of dynamically allocated time slots fits the bit rate and bit error rate (BER) retirements. Transparent bearers, will thus be available in the entire GSM cell, but require fewer time slots in the center of the cell (where 8-PSK coding schemes can be used).

2.1.2. Frequency Planning

Most mature GSM networks of today have an average frequency reuse factor of around 9 (meaning that available frequencies are divided into nine frequency groups). However, there is also a trend toward tighter reuse factors. With the use of frequency hopping, multiple reuse patterns (MRP), and discontinuous  transmission  (DTX), reuse factors as low as 3 become feasible. EDGE supports a variety of reuse patterns. In fact, by its use of link quality control, EDGE can be introduced in an arbitrary frequency plan, and benefit from high SIR closer to the base stations. EDGE can be introduced in an existing GSM frequency plan, and that it also supports future high-capacity solutions based on tighter frequency reuse.

2.1.3. Radio Network Planning

An important prerequisite (and to a large extent, one that will determine the success of Edge) is that network operators should be able to introduce Edge gradually. The initial deployment of Edge-capable transceivers will supplement standard GSM transceivers in a subset of cells where Edge coverage is desired. An integrated mixture of circuit-switched, GPRS and Edge users will thus coexist in the same frequency band. To minimize operator efforts and costs, Edge-related implementation must not require extensive modification of the radio network plan (including cell planning, frequency planning, the setting of power levels and other cell parameters).

2.1.4. Channel Management

After Edge has been introduced, a cell will typically include two types of transceiver: standard GSM transceivers and Edge transceivers. Each physical channel (time slot) in the cell can be viewed as being one of at least four channel types:

1. GSM speech and GSM circuit-switched data (CSD);

2. GPRS packet data;

3. Circuit-switched data, enhanced circuits witched data (ECSD), and GSM speech;

4. Edge packet data (EGPRS), which allows a mix of GPRS and EGPRS users simultaneously.

While standard GSM transceivers only support channel types 1 and 2, Edge transceivers support all four channel types. Physical channels are dynamically defined according to terminal capabilities and needs in the cell. For example, if several speech users are active, the number of type-1 channels is increased, at the expense of GPRS and Edge channels. Obviously, channel management must be automated, to avoid the splitting of channels into static groups. Otherwise, trunking efficiency would diminish.

3. Interleaving

To increase the performance of the higher coding schemes in EGPRS (MCS7 to MCS9) even at low C/I, the interleaving procedure has been changed within the EGPRS standard. When frequency hopping is used, the radio environment is changing on a per-burst level. Because a radio block is interleaved and transmitted over four bursts for GPRS, each burst may experience a completely different interference environment. [7]

If just one of the four bursts is not properly received, the entire radio block will not be properly decoded and will have to be retransmitted. In the case of CS4 for GPRS, hardly any error protection is used at all. With EGPRS, the standard handles the higher coding scheme differently than GPRS to combat this problem. MCS7, MCS8 and MCS9 actually transmit two radio blocks over the four bursts, and the interleaving occurs over two bursts instead of four. This reduces the number of bursts that must be retransmitted should errors occur. The likelihood of receiving two consecutive error free bursts is higher than receiving four consecutive error free bursts. This means that the higher coding schemes

for EDGE have a better robustness with regard to frequency hopping.

4. EDGE & GPRS

EDGE, or the Enhanced Data Rate for Global Evolution, is the new mantra in the Global Internet Connectivity scene. EDGE is the new name for GSM 384. The technology was named GSM 384 because of the fact that it provided Data  Transmission  at a rate of 384 Kbps. It consists of the 8 pattern time slot, and the speed could be achieved when all the 8 time slots were used. The idea behind EDGE is to obtain even higher data rates on the current 200 KHz GSM carrier, by changing the type of the modulation used.

Now, this is the most striking feature. EDGE, as being once a GSM technology, works on the existing GSM or the TDMA carriers, and enables them to many of the 3G services. Although EDGE will have a little technical impact, since its fully based on GSM or the TDMA carriers, but it might just get an EDGE over the up coming technologies, and of course, the GPRS. With EDGE, the operators and service providers can offer more wireless data application, including wireless multimedia, e-mail (Web Based), Web Infotainment, and above all, the technology of Video Conferencing.

Now all these technologies that were named earlier, were the clauses of the IMT-UMTS 3G Package. But, with EDGE, we can get all these 3G services on our existing GSM phones, which might just prove to be a boon to the user.

The current scenario clearly states that EDGE will definitely score higher than GPRS. The former allows its users to increase the data speed and throughput capacity, to around 3-4 times higher than GPRS.

Secondly, it allows the existing GSM or the TDMA carriers to give the sophisticated 3G services. And with 1600 Million subscribers of GSM in over 170 countries, offer the full Global Roaming, anywhere between India to Japan and to San Francisco. Based on an 8 PSK modulation, it allows higher bit rate across the air Interface. There is one symbol for every 3 bits. Thus, EDGE Rate is equal to 3x GPRS Rate.

5. Future Evolution Towards WCDMA

The next evolutionary step for the GSM/EDGE cellular system includes enhancements of service provisioning for the packet-switched domain with the service provisioning in UMTS/UTRAN (UMTS terrestrial radio access network). GERAN will provide improved support for all quality of service (QoS) classes defined for UMTS: interactive, background, streaming and conversational. By doing so, a new range of applications, including IP multimedia applications, will be adequately supported. This part of the GSM/EDGE evolution focuses on support for the conversational and streaming service classes, because adequate support for interactive and background services already exists. Additionally, parallel simultaneous bearers will support multimedia applications with different QoS characteristics towards the same MS, such as multiple media streams handled through IMS domain. A driver for such evolution on the packet-switched side is the paradigm shift within the telecommunications world from circuit to packet-switched communications.

Both the core network defined for GPRS and the current GSM/EDGE radio access network require modifications to support enhanced packet services. The GPRS/EGPRS networks can quickly and cost effectively evolve with market needs, and align with services provided by WCDMA networks. The current evolution of GSM/EDGE, which covers all of the above aspects, is being standardized in 3GPP TSG GERAN. [4]

6. EDGE in Pakistan

Pakistan has the sixth largest population in the world – approximately 150 million. There are currently four mobile operators in the country. Mobile penetration at the end of 2003 was just 2.3% with a subscriber base of 3.4 million, while fixed line penetration was approximately 2.4%. Many geographic areas in Pakistan are without telephone coverage. To accompany recent positive economic development in Pakistan and the inherently low mobile penetration, high growth within the mobile segment is expected. At the moment the people in Pakistan are more concern with the text-enabled facility like SMS. Although the introduction of GPRS gave a new concept and new boost in Cellular network but still, people are not that much concern using Internet by their terminal. Few think that it still more costly and few believe that GPRS didn’t develop the interest for using Internet if we compared it by computer.

In April 2004 Norwegian mobile telecom operator, Telenor, bid for and ultimately won a license to operate a cellular network in Pakistan. The license covers the operation of Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology for the network. [14]

Telenor Pakistan has signed two deals with mobile infrastructure contractors for different areas of the network:

Nokia have signed a three-year deal to build and operate a GSM / GPRS / EDGE network to cover the central and Northern Punjab region (phase one), centered around Lahore.

Siemens have signed a deal to build a GSM / GPRS / EDGE network to cover the southern areas of Pakistan, centered around Islamabad.

Further enhancements in data capability over the core GPRS / GSM network will be provided in both networks with the installation of Enhanced Data for Global (GSM) Evolution technology. This component of the two systems will be installed after the initial roll-outs and will allow the subscribers to have the use of advanced mobile services such as downloading video and music clips, full multimedia messaging, high-speed color Internet access and email on the move.

Nortel Networks will upgrade Ufone’s existing wireless systems and supply new GSM/GPRS core network and radio access equipment, including Mobile Switching Center, Home Location Register (HLR) and advanced Base Transceiver Stations (BTS).

A key component of the Ufone expansion will be Nortel Networks BTS 12000, designed to deliver additional capacity within a GSM/GPRS network while positioning operators to drive lower costs and to offer advanced wireless services based on third generation (3G) EDGE (Enhanced Data for GSM Evolution) technology. The expansion will also include Nortel Networks Passport Packet Voice Gateway (PVG) for migration of TDM voice trunking to a packet-based infrastructure.

7. Benefits

As highlighted previously the need to reduce business risk and make the best use of existing resources is of paramount importance within today’s business environment.

7.1. Financial

GSM based networks have become the standard within the cellular landscape. As EDGE is a GSM based technology and provides an enhancement for GPRS at a little additional cost it is considered the best way in which to capitalize on existing resources. [1]

7.1.1. Radio Access Network

In most cases GPRS enabled base stations and BSC’s can be simply upgraded to EDGE by way of relatively low-cost software and hardware upgrades, which will pro-long the life cycle of the deployed RAN elements.

7.1.2. Core Network

For GPRS enhancement, there is very little modification to be completed within a GPRS enabled core network, thus enhancing the sunk core network investment.

7.1.3. Antenna Sites

There is no requirement for additional antenna sites when deploying EDGE. Assuming high quality linear amplifiers with high RF output power are used within the BTS, the coverage pattern will be the same as the existing GPRS deployment, so protecting existing site investment.

7.1.4. Spectrum Utilization

EDGE triples the GPRS data capacity whilst using the existing GSM spectrum and offers up to three times the GPRS data rate to the end user. EDGE is spectrally the most efficient radio technology for data applications requiring up to 100Kb/s throughput (compared to CDMA and WCDMA), and only WCDMA is spectrally better for higher throughputs.

7.1.5. Applications

GPRS enabled applications and services will generally not require any additional investment to become EDGE compatible. This is also valid for known WCDMA applications.

Although the financial benefits of EDGE can be apportioned to individual network elements as outlined above, one of the main business drivers is that EDGE forms an essential part of the overall GSM evolution towards a seamless multi-radio GSM/ GPRS/EDGE/WCDMA network. As mentioned previously GSM is the main standard for cellular communications worldwide and the business benefits of deploying an industry standard technology can be seen in nearly every aspect of a network deployment, from end-user devices, to applications to hardware.

7.2. For Operator

Operators can also experiences the advantages of EDGE in following ways.

7.2.1. Migration to wireless multimedia services

The operator can increase data revenues by offering attractive new types applications to end-users.

7.2.2. Improved customer satisfaction

Increased data capacity and higher data throughput will decrease response times for all data services, thus keeping end users satisfied and connected.

7.2.3. Early deployment of 3G type applications

EDGE networks are expected to emerge in year 2001, when mature markets are likely to start demanding multimedia applications.

7.2.4. Quick network implementation

EDGE will not require new network elements and EDGE capability can be introduced gradually to the network.

7.3. For User

7.3.1. Improved quality of service

Increased data capacity and higher data throughput will eventually satisfy the customers’ need for QoS.

7.3.2. Personal multimedia services

Attractive new types of applications and terminals will become available.

7.3.3. Potentially lower price per bit

Lower cost of data capacity for high-speed data applications gives the operator flexibility in pricing.

8. Conclusion

While the tug of war between access technologies – CDMA vs. UMTS vs. GSM — continues to be debated globally, EDGE provides an ideal solution for GSM carriers to add data capacity using limited spectrum. Keeping in view the fact that GSM supports more subscribers today than any other access technology (roughly 65 to 70% of the global subscriber market), and that GSM/GPRS operators are scrambling to add capacity to support user growth and launch next generation data services, the increased capacity and throughput offered by EDGE becomes very compelling. And, in a market where wireless carriers must squeeze the most out of capital outlays–past and future, it is no real surprise that we are going to see a renewed wave of interest in EDGE from our GSM customers.

Today the position of EDGE as a technology evolution of GSM is clear. Initially promoted as an alternative to WCDMA and generally a niche technology, EDGE is now regarded as a key enabler for GSM/EDGE and WCDMA operators alike. Being able to drive business value from existing GSM infrastructure and spectrum is one of the main advantages, and along-with the ability of EDGE to reduce CAPEX, time-to-market and time-to-revenue, with regards the delivery of global high-speed data services, EDGE is a must technology.

The cellular companies working in Pakistan did not have the license for the EDGE. Now as the introduction of some new companies like Telenor and WARID, it is possible that in near future Pakistan will also be able to use this facility. Then GPRS can become a real important factor in cellular network, as the people in Pakistan will use the Internet not only for downloading ring tones but also can enjoy the streaming videos by their cell phone and so many other facilities.
