The editors of the “GSM, GPRS & EDGE Performance” book
Trang 22(Taken from GSM, GPRS and EDGE Performance, 1st Edition)
I have worked in the mobile communications industry longer than I would like to admit
In the early 1970s, I started my career as a radio engineer for Motorola At that time,Motorola designed and manufactured low-, mid- and high-tier private land mobile radios.Motorola had few competitors for the mid- and high-tier product lines (50- to 100-Wradios) However, in the low tier, less than 25-W radio category, there were numerous con-tenders, mostly from European manufacturers with a ‘Nordic Mobile Telephone’ heritage.But times were changing In the late 1970s, the American public got their first taste
of mobile communications when Citizen Band (CB) radio became popular (‘10–4, goodbuddy’) It was an unlicensed, short-range, ‘party-line’ experience Those skilled in theart knew that something better was needed And the American communications industryresponded The Federal Communications Commission and major industry players, likeAT&T and Motorola, specified America’s first public mobile radio telephone system,AMPS (Advanced Mobile Telephone System) By the mid-1980s, AMPS was a proventechnology and cellular subscriber growth was constantly exceeding forecasts
By the early 1990s, cellular technology had become so popular that the first-generationanalog systems could not keep up with the demand New second-generation digital sys-tems were developed to address the capacity shortfall In the United States, three digitaltechnologies were standardized and deployed: IS-136 (a TDMA technology utilizing theAMPS 30-kHz structure), IS-95 (a 1.25-MHz CDMA carrier scheme) and GSM (theEuropean 200-kHz TDMA standard) This multi-standard wireless environment provided
a unique proving ground for the three technologies While IS-136 and IS-95 engaged
in ‘standards wars,’ GSM gained a foothold in America At the same time, GSM wasachieving global acceptance because it offered a rich selection of capabilities and fea-tures that provided real incremental revenues for operators As more and more countriesadopted the technology, GSM experienced tremendous economies of scale for everythingfrom chipsets to handsets, infrastructure and applications
While the industry continued to experience stellar growth, American manufacturerdominance was challenged by Nordic companies, especially for the GSM technology.They brought to the United States, innovative, competitively priced products, backed bytalented communications professionals with years of experience in designing, manufac-turing, engineering and installing cellular equipment and systems throughout the world
By the late 1990s, the Internet was pervasive and the wireless industry looked to mobiledata as the growth opportunity Once again, the industry undertook the task of definingnew wireless systems—this third generation, 3G, was to be based on packet data Threenew wireless standards emerged; CDMA2000 (evolution of IS-95), EDGE (evolution of
Trang 23GSM for existing spectrum) and WCDMA (evolution of GSM for new spectrum using a5-MHz WCDMA carrier).
The evolution of GSM to 3G is about gradually adding more functionality, possibilitiesand value to the existing GSM network and business The evolution begins with anupgrade of the GSM network to 2.5G by introducing GPRS technology GPRS providesGSM with a packet data air interface and an IP-based core network EDGE is a furtherevolutionary step of GSM packet data EDGE can handle about three times more datasubscribers than GPRS, or triple the data rate for one end-user EDGE can be achievedthrough a very fast and cost-effective implementation The only requirement is to addEDGE-capable transceivers and software
With the continuation of EDGE standardisation towards GERAN (GSM/EDGE Radioaccess network), EDGE will achieve a full alignment with WCDMA The goal for EDGE
is to boost system capacity, both for real-time and best-effort services, and to becomeperfectly competitive with other 3G technologies
What emerges with these evolutionary steps from GSM to GPRS, EDGE and WCDMA
is a seamless 3G UMTS (Universal Mobile Telecommunications System) Multi-Radionetwork, one that maximizes the investments in GSM and GPRS
It stands to reason that both EDGE and WCDMA will be mainstream 3G UMTSproducts from Nordic companies This book, written by engineers from one of theseNordic companies, is an authoritative treatise on GSM evolution to 3G The book provides
an in-depth performance analysis of current and future GSM speech and GPRS/EDGEpacket data functionality Furthermore, the concept of a 3G UMTS Multi-Radio network(GSM/EDGE/WCDMA) is presented in depth as the best solution for wireless operators
to evolve their networks towards 3G
Times change, but some things do not Nordic companies have been at the forefront
of wireless communications for more than a half of a century They have earned theirpre-eminent position in the industry I encourage you to listen to what this book has
of these products and services As occurred with electricity, the automobile and the sion, soothsayers often misread the long-term impact of these inventions, underestimatingqualities that led to their long-term success and adoption by the masses Ultimately, allthree inventions had tremendous social and economic impact on global societies, and thesoothsayers were proven to have undervalued the importance of these great inventionsover time
televi-In a slightly different way, the future of EDGE has been understated, underestimated,and undervalued by the latest pundits Over the last few years, several global wireless orga-nizations, including the GSA, the UWCC and now 3G Americas have stood their ground
Trang 24as advocates for EDGE because of the merits of the technology and its value to operatorsand customers as a spectrally efficient and cost-effective solution for third-generation (3G)wireless services 3G Americas is firm in their belief that a comparative review of howEDGE meets three key criteria, performance, cost and the ease of transformation to 3G,will show that EDGE is indeed a superior technology choice.
The Reality of EDGE
On October 30, 2001, Cingular Wireless with its vendor partners announced its ment to become the first operator in the world to deploy EDGE at 850 and 1900 MHz.With over 22-million wireless customers, Cingular is a major player in the global wire-less marketplace The reasons cited by Cingular for its EDGE selection included capacityand spectral efficiency competitive with any other technology choice (performance), theability to deploy 3G EDGE in existing spectrum including 850 MHz (cost), a total capitalcost of about $18 to $19 per Point of Presence (POP) in TDMA markets with plenty ofgo-forward capacity (cost), ridiculously low cost to upgrade the GSM network (only 10 to
commit-15 percent of the network’s cost), the enormous economies of scale and scope offered bythe family of GSM technologies, ensuring the availability of equipment and applications
at the lowest possible cost, and a transition path through GSM and GPRS achievableseamlessly through the use of the GAIT terminal (GSM-TDMA phone) that will easetransformation and result in customer retention
Similarly, almost a year before Cingular’s announcement, AT&T Wireless Servicesannounced its commitment to EDGE As of November 2001, reported operator com-mitments to EDGE in the Americas encompassed hundreds of millions of potentialcustomers These commitments validate the future of this third-generation technology.Cingular’s commitment to EDGE in the 850-MHz band sets the stage for an accelerateduptake by operators throughout the Western Hemisphere Regional US operators and manyLatin American operators will find the opportunity to deploy EDGE in 850 MHz espe-cially appealing Furthermore, these commitments increase the possibility that Europewill recognize that EDGE’s capacity and cost qualities make it an important comple-mentary technology to WCDMA As spectrum shortages inevitability occur in Europe,EDGE will provide an excellent solution for GSM operators as a complement to theirWCDMA networks
of scale played a key role in the Cingular decision
Another major benefit of EDGE cited by operators is that it enables TDMA andGSM carriers to offer 3G services while still realizing lower costs due to higher spec-tral efficiency and higher data rates With the implementation of Adaptive Multi-Rate
Trang 25(AMR) Vocoders, and Frequency Hopping, GSM is competitive with CDMA on spectralefficiency, which translates into higher capacity and faster data rates EDGE offers trans-mission speeds of 384 kbps—fast enough to support full motion video—and throughputcapacity 3 to 4 times higher than GPRS Thus, EDGE is fast, EDGE is efficient andEDGE performs.
Additionally, the opportunity for international roaming with the GSM family of nologies offers yet another major incentive for operators to provide their customers withseamless communications services Since EDGE and WCDMA will operate on the sameGPRS core network, the EDGE/WCDMA customer will be able to travel the worldseamlessly, staying connected with one number and one device
tech-Conclusion
EDGE will contribute to a bright future for 3G services, a vision shared by major analystsand industry groups The Strategist Group predicts that revenue from wireless data willreach $33.5 billion globally by 2004 Frost & Sullivan expects that the proportion ofoperator revenues derived from non-voice services will be in excess of 45% by 2006 AUMTS Forum survey has estimated that non-voice revenues may take over voice revenues
by 2004, while simple voice revenues will remain a critical revenue component comprising34% of annual revenues in 2010 The UMTS Forum study also predicts that 3G revenues
of $37.4 billion in 2004 will increase to $107 billion by 2006 All in all, predictions mayvary but the consensus is clear that results will be positive for third-generation services.This work offers the reader more than an evolutionary technical strategy of GSM’stransition to 3G It also provides a set of benchmarks for a core evaluation of the merits
of EDGE as a central component of the wireless industry’s fulfilment of its promise forhigher degrees of service and convenience This process is already being established, asevidenced by the first live EDGE data call completed by Nokia and AT&T Wireless onNovember 1, 2001 The connection of an EDGE handset with a laptop to the Internet forweb browsing and streaming applications marked the first successful completion usingEDGE 8-PSK modulation in both directions in the air interface Indeed, it is anothersign that EDGE will flourish in this new billion-dollar marketplace as a leading 3Gtechnology in the Americas owing to its performance, cost, interoperability and ease oftransformation EDGE will outlast the neigh-sayers and in the long term, EDGE will farexceed expectations And just as electricity, the automobile and the television changedour lives, EDGE will change our lives by providing 3G services for the masses
to those operators, like ourselves at Cingular Wireless, who have been intimately involved
in actually deploying the latest new GSM networks At Cingular Wireless, we have been
Trang 26especially fortunate to be among those who have ‘tasted’ the first fruits of many of thecutting-edge GSM advances and topics covered in this book, such as AMR, EDGE, QoSdimensioning and so on, as we, along with our four BSS vendors—Nokia, Ericsson,Siemens and Nortel—have worked together to turn the new technology described in thisbook into reality over the last two years.
Since 2002 to the date of this writing, Cingular has overlaid more than 10 000GSM/EDGE base stations on top of its existing IS-136 TDMA network across the UnitedStates All GSM base stations are now operating with live commercial traffic on AMR,while some selected markets are launching EDGE In addition, we have pioneered theintroduction of GSM into the 850-MHz band, which represents a significant milestonefor GSM in penetrating the original cellular band in the United States, which has beenhome to four other air interfaces since the first in-service analog cellular networks weredeployed in the early 1980s Although providing spectrum for GSM in these 850 marketsoriginally appeared as insurmountable, it has been systematically overcome and mastered
by transforming some of the network simulators and tools described here in subsequentchapters, which were originally reserved for only research activity, into tools that canassist in the evaluation and planning of the high spectral efficiency techniques such as thetight (≤12) BCCH and small frequency hopping pools with the high capacity (fractionalload) needed for narrowband GSM deployment
Throughout this GSM overlay journey at Cingular, our engineers have found the rial in this book invaluable, as, in comparison to many other theoretical books or papersthat simply explain the standards, this book provides many examples of real-world fieldtrials to back up the theory and, in some cases, illustrate what is practically achievable.With our successful deployment of AMR and EDGE, Cingular is pleased to continue thistradition and provide, in some small part, a portion of our field-trial results on several ofthese new GSM advances herein
mate-Nevertheless, what is continually exciting is that the technology evolution and serviceapplicability of GSM/EDGE is far from over, whereas, although much of the global focushas been on ‘UMTS’ and its promises, the GSM community has been quietly advancingthe state of the art through continually ‘upgrading the engine’ on a tried and true frame.For instance, in technology advancement, several new receiver algorithms have beendiscovered for the GMSK modulation used in GSM AMR/GPRS, which exploit somenovel properties of the modulation to effectively create diversity with a ‘virtual secondantenna’, which may then be used for interference cancellation These ideas have spawned
a feasibility study in GSM standards (GERAN) called Single Antenna Interference lation (SAIC), which calls for applying these results for improved receiver performance
Cancel-in GSM mobile stations PrelimCancel-inary simulation and field-trial results are shown here withpromising results, which, if deployed in synchronized networks could push GSM voicecapacity above currently stated CDMA/WCDMA capacities In the future, it would notcome as a surprise if the SAIC ideas are extended to other modulations (e.g 8-PSK used
in EDGE), and other air interfaces as well
In applications and data services, it seems that all operators and vendors, even fromcompeting technologies, are still in the initial stages of attempting to move from ‘best-effort’ delivered data to those services that require the illusive end-to-end quality ofservice New applications such as push-to-talk over GPRS/EDGE are just beginning to bedeployed now as the move toward increasingly full conversational services over packet
Trang 27data are pursued Success in this realm is, without any doubt, going to require newdimensioning, features and planning techniques, which are also described in subsequentchapters It is these techniques coupled with finding the right mix of services that alloperators and vendors strive for to keep the profitability and revenue stream intact whileproviding the additional functionality to maintain and attract new customers.
There is no doubt about the fact that many things are yet to be discovered in nology, planning and optimization of voice and data services as we enter a new realmwhere the Internet and wireless converge and people become used to ‘always-on’ services.Understanding how to provide these effectively with GSM/EDGE in a truly ‘field-real’manner is the focus of this book I trust that you will find it as useful and relevant as wehave at Cingular Wireless

Trang 28GERAN: Evolution towards 3G/UMTS
The wireless market has experienced a phenomenal growth since the first generation (2G) digital cellular networks, based on global system for mobilecommunications (GSM) technology, were introduced in the early 1990s Since then,GSM has become the dominant global 2G radio access standard Almost 80% of today’snew subscriptions take place in one of the more than 460 cellular networks that useGSM technology This growth has taken place simultaneously with the large experiencedexpansion of access to the Internet and its related multimedia services
second-Cellular operators now face the challenge to evolve their networks to efficiently supportthe forecasted demand of wireless Internet-based multimedia services In order to do this,they need to perform a rapid technology evolution rolling out new third-generation (3G)radio access technologies, capable of delivering such services in a competitive and cost-effective way There are multiple recognised 3G technologies, which can be summarisedinto two main 3G evolution paths The first one to be conceived and developed, andthe more widely supported, is UMTS multi-radio (universal mobile telecommunicationssystem), and the second one is cdma2000
The first part of this book will describe the evolution GSM experienced after 5 years ofcontinuous standardisation effort, and how the result of such an effort has provided GSMnetworks with a smooth, competitive and cost-efficient evolution path towards UMTS.The first steps of this evolution took place in Rel’97 standards, when general packet radiosystem (GPRS) was introduced to efficiently deliver packet-based services over GSMnetworks Later, adaptive multi-rate (AMR), included in Rel’98, increased the spectral effi-ciency and quality-of-speech services to remarkable limits Enhanced data rates for globalevolution (EDGE) was introduced in Rel’99 and introduced more efficient modulation,coding and retransmission schemes, boosting the performance of data services Release
99 also included the support of the UMTS traffic classes; hence providing the meansfor EDGE to support from the very beginning the same set of 3G services that UMTSwas designed for This synergy is completed in Rel’5 with the development of GERAN,
a new radio access network architecture, based on GSM/EDGE radio access gies, which is fully harmonised with UTRAN (UMTS terrestrial radio access network)through a common connectivity to the UMTS core network, and therefore integrated in theUMTS frame Today, UMTS standardisation, carried out by the 3rd Generation Partner-ship Project (3GPP) standardisation body, jointly develops the GERAN and UTRAN as

part of the same concept, 3G UMTS multi-radio networks This GSM evolution towardsUMTS is illustrated in Figure 1
Chapters 1 and 2 will provide a detailed description of the GSM evolution Chapter 3will provide an in-depth analysis of the GERAN quality-of-service (QoS) support indifferent releases Finally, Chapter 4 will present the different standardised methods tosupport location services, their architecture and expected accuracy
The second part of the book will thoroughly cover the performance efficiency of thetechnologies associated with the GSM evolution Radio network performance is vital inorder to maximise the return on investment from operators Not only does it provide theability to increase the capacity of the networks but also improves the QoS experienced
by the end users All the performance-related dimensions, such as link level voice anddata performance, spectral efficiency, maximum and realistic data rates and service supportcapabilities are studied in depth in this part Chapter 5 introduces the principles associatedwith GSM radio network performance analysis All standardised functionality, such asAMR, SAIC, GPRS and EDGE, both for voice (Chapter 6) and data (Chapter 7) services,are carefully studied Chapter 8 presents the relevant end-used performance aspects asso-ciated with the most relevant packet data services Non-standardised solutions will beanalysed as well in order to provide an overall perspective of the potential GSM/EDGEperformance when advanced functionality such as dynamic channel allocation (Chapter 9)
or link level enhancement (Chapter 11) techniques are introduced Chapter 12 analyses thesignalling channel’s performance, since this may limit the overall network performance
A specific chapter on narrowband deployment scenarios (Chapter 10) will provide theguidelines to maximise the performance in these demanding radio conditions
