nanoBTS™ EDGE/AMR The new nanoBTS EDGE/AMR picocellular basestation represents a significant step on the migration path to higher data rates and more supported users. Based on the world beating nanoBTS GSM/GPRS basestation it delivers the same features and functionality for GSM voice and GPRS but with the addition of high-speed EDGE data and improved voice quality and capacity using AMR coding. For operators moving to higher speed data networks by deploying EDGE, there is a strong requirement to provide high quality coverage in buildings. With ip.access revolutionary GSM-over-IP technology it is possible to bring cost effective high-speed coverage to the user where they most need and use it. nanoGSM™ GSM-over-IP picocells for in-building coverage and capacity increased data capacity For many of the new data services the majority of use will be indoors where the EDGE BTS will be physically close to the user. The quality of the signal can be correspondingly higher, so the higher rate data coding schemes will be available to the user. The nanoBTS EDGE/AMR supports all the EDGE coding schemes from MCS1- MCS9 giving a maximum nominal data rate of 414kpbs which is up to three times the maximum data rate of the GSM/GPRS model. The BTS also monitors for the optimum RF conditions for data transfer and alters the data throughput to achieve the fastest rates This ensures the best possible user experience and maximizes the use of the available spectrum. improved voice quality and capacity In networks where AMR capable handsets are being deployed the new coding scheme can be used to improve the quality of voice calls, improving the user experience. In addition, as the quality of the AMR half rate coding is very similar to the standard full rate GSM, half rate AMR can be used to double the number of voice channels available per BTS. Erlang models show that this increases the number of supported users by up to three times, improving the return on investment for the BTS. easy deployment Picocells offer a lower cost alternative to the traditional antenna based approach to providing GSM coverage and capacity within buildings. Due to the small size and deployment flexibility, the nanoBTS can easily achieve coverage where needed. The quick and simple installation using existing Ethernet wiring for both data and power avoids the need for the expensive site surveys, cabling installations and access to roof and floor spaces typical of distributed antenna systems (DAS). The unique Network Listen™ function supplements the conventional RF planning process, allowing the planners to see into the difficult indoor environment to optimize the coverage. For operators with existing nanoBTS deployments the EDGE unit can be added to an existing installation using the multi TRX capability. Both units then operate as a single cell to give up to 22 channels of voice together with the high data rates of 414kbps of the highest EDGE coding schemes. scalable system architecture The nanoBTS is a complete GSM basestation that conforms to the picocell standard and delivers “GSM-over-IP”. It combines a standard Um air interface, which supports the more than 1 billion GSM handsets in use globally, with an IP based backhaul, which can take advantage of the existing IP broadband infrastructure. There are two versions of the nanoBTS EDGE/AMR for operation in the 1800 and 1900MHz GSM frequency bands. For applications requiring even greater capacity up to 4 nanoBTS can be combined into a multiple TRX cell, increasing the number of supported users per TRX by up to 200%. The nanoBTS GPRS/GSM and the nanoBTS EDGE/AMR are controlled by the nanoGSM BSC basestation controller. System configuration, performance and fault reporting is handled by the nanoGSM OMC-R management system. key features  Up to 3 times the data rate with EDGE support  Up to 3 times the number of supported users with half rate AMR  Support for EDGE coding MCS1-MCS9  Indoor coverage up to 125,000m2  Single 10/100 Ethernet connection  Smallest footprint in the industry applications  Dedicated coverage for SME premises  In-building capacity and coverage for large corporate offices  Stand-alone in-fill for shopping malls, airports or undergrounds  Delivering GSM access on ships, aeroplanes and rural areas
