  • 1. nanoGSM™ GSM-over-IP picocells for in-building coverage and capacity nanoBTS™ GPRS/GSM The nanoBTS is a complete picocellular basestation for deployment in buildings to provide GSM and GPRS coverage and capacity. With the smallest and most cost-effective package available today, its use of IP for backhaul ensure it can be installed wherever and whenever capacity and coverage are required. ip.access has developed the nanoBTS in accordance with ETSI standards which guarantee compatibility with existing handsets as well as both today’s circuit-switched and tomorrow’s IP-based networks. revolutionary deployment Picocells offer a lower cost alternative to the traditional antenna based approach to providing GSM coverage and capacity within key features buildings. Due to the small size and deployment flexibility, the Rapid installation using existing IP infrastructure nanoBTS can easily achieve coverage where needed. The quick Standard radio interface compatible with all GSM handsets and simple installation using existing Ethernet wiring for both data Multi-TRX capability to support large numbers of users and power avoids the need for the expensive site surveys, cabling Typical indoor coverage up to 125,000m2 installations and access to roof and floor spaces typical of Excellent data rates with GPRS support distributed antenna systems (DAS). Single10/100 Ethernet connection incorporating power, traffic and signaling The nanoBTS is so flexible that single BTS installations can make Smallest footprint in the industry use of DSL to provide the connection back to the basestation controller. This makes it possible to offer dedicated coverage solutions for premises with as few as 10 staff cost effectively. applications Dedicated coverage for SME premises with DSL based link The nanoBTS also simplifies cell and frequency planning; with it’s In-building capacity and coverage for large corporate ability to monitor other GSM basestations in the area by using the offices revolutionary Network Listen™ capability it gives the frequency Stand-alone in-fill for shopping malls, airports or planners a unique view of actual signal strengths on the ground. undergrounds Delivering GSM access on ships, aeroplanes and rural areas system architecture The nanoBTS is a complete GSM basestation that conforms to the picocell standard. 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. The nanoBTS uses a variation of the standard Abis interface, but carried over IP so that it can be connected back over a wide variety of IP networks. This brings the advantage of the cost structures of IP based networks to the existing population of deployed handsets, maximising the potential return for the operator. Several varieties of nanoBTS are available, permitting operation in the 900, 1800 and 1900MHz GSM frequency bands. For applications requiring 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 nanoGSM range incorporates nanoBTSs with a basestation controller (nanoGSM BSC) and a management system (nanoGSM OMC-R) that supports the configuration, performance and fault reporting of the radio network.
