  • 1. nanoGSM™ GSM-over-IP picocells for in-building coverage and capacity nanoGSM™ system The nanoGSM system is a complete picocell basestation system providing in-building GSM and GPRS coverage and capacity. It includes the nanoBTS™, the smallest and most cost-effective basestation available today, together with the base station controller and operation management software needed to integrate with existing mobile networks. Taking advantage of the more than 1 billion GSM handsets in use globally together with existing IP based broadband infrastructure for backhaul, the nanoGSM system enables operators to provide cost-effective tailored capacity and coverage for target customers and deliver excellent return on investment. system architecture The key element of the nanoGSM system is the nanoBTS picocellular basestation, which is deployed on the customer’s site. key features The nanoBTS is a complete GSM basestation that conforms to the Smallest fully functional BTS in the industry picocell standard and delivers “GSM-over-IP”. It combines a IP based backhaul reduces costs standard Um air interface to the handset, with an Abis interface Indoor coverage up to 125,000m2 carried over IP for the backhaul. This brings the advantage of the Available for 900, 1800 and 1900MHz bands cost structures of IP based networks to the existing population of Compliant with GSM picocell specification deployed handsets, maximising the potential return for the Integrates with existing MSCs or softswitch MSC operator. Alarm management integration Single Ethernet connection to BTS including power The nanoBTS is configured and controlled by the nanoGSM BSC basestation controller, which is usually co-located with the MSC and provides standard A and Gb interfaces to the operator’s MSC applications and SGSN. Operational management of the whole system is Dedicated coverage for SME premises provided by the nanoGSM OMC-R, which supports the In-building capacity and coverage for large corporate configuration of the system together with performance and alarm offices monitoring. Stand-alone in-fill for shopping malls, airports or undergrounds Delivering GSM access on ships, aeroplanes and rural revolutionary deployment areas 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). nanoGSM is so flexible that single nanoBTS installations can make 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. The nanoGSM system also simplifies cell and frequency planning; with the ability to remotely monitor other GSM frequencies in use in the area with the revolutionary Network Listen™ capability. This gives frequency planners a unique view of actual signal strengths on the ground.
