3G Americas Demystifies GSM Voice Capacity
Posted: 18-Jul-2002 [Source: 3G Americas press release]

[New white paper concludes carriers that transform their TDMA networks to the world standard GSM wireless technology can double their voice capacity. ]

3G Americas today published a white paper written by independent expert Peter Rysavy of Rysavy Research concluding that wireless carriers that transform their TDMA networks to the world standard GSM wireless technology can double their voice capacity.

Rysavy Research is an independent consulting firm founded by Peter Rysavy that provides clients with fundamental insight into wireless markets and wireless technologies. Rysavy Research utilized numerous internal and external sources including vendors and operators to compile a composite view of GSM voice capacity. "The conclusions in this white paper are well supported by the industry," stated the author, Peter Rysavy. "There are many enhancements available, both now and in the future, that will boost GSM capacity, such as frequency hopping, advanced radio planning, and new voice compression methods."

Conclusions of the paper indicate that with GSM innovations:

GSM maximizes capacity to sixteen times first generation analog wireless service (AMPS) using the new Adaptive Multi-rate Codec (AMR) GSM today has almost double the capacity of TDMA -- and with AMR the gains will quadruple GSM voice capacity is equal to, or better than, CDMA2000 Single Antenna Interference Cancellation (SAIC), still in development, will provide an additional increase of 60-100% in voice capacity, making GSM the most spectrally efficient technology for speech services Beyond GSM, UMTS provides additional capacity, quality-of-service mechanisms, and flexibility in managing resources between voice and data services "There has been considerable speculation on the part of industry pundits regarding the issue of GSM capacity versus other technologies. This white paper by Rysavy Research provides the proper explanation of the technical benefits of the GSM standard that the industry has been waiting for," remarked Bill Clift.

As the world's leading wireless technology, GSM is used in more than 75% of the world's digital wireless phones and in more than 175 countries.

The founding members of 3G Americas include AT&T Wireless (USA), Cingular Wireless (USA), Ericsson, HP, Lucent Technologies, Motorola, Nokia, Nortel Networks, Openwave Systems, Rogers Wireless (Canada), Siemens, and Telecom Personal (Argentina).
