Kiev Metro goes mobile with ip.access nanoBTS™

- ip.access wins contract to supply nanoBTS™ units, the world’s smallest GSM-over-IP basestations and associated infrastructure
- Kiev becomes first city in the world to deploy GSM-over-IP mobile solution in the Metro
- Solution to deliver mobile coverage to over one million commuters each day

Cambridge, January 26th — ip.access ltd., a wholly-owned subsidiary of TTP Communications Plc (LSE:TTC), today announces a deal with Proximus L.L.C., a Ukrainian company, which will see ip.access supply its nanoBTS™ GSM basestations for installation in the below-ground section of the Kiev Metro. The application is a world first, blending GSM and IP technology to provide underground coverage to over 1.7 million Kiev commuters per day. Proximus has an agreement with the Kiev Metro to lease space and communications infrastructure to install the subsystem which in turn will be subleased to mobile network operators. The first network operator to sign up is UMC (Ukrainian Mobile Communications), the biggest GSM operator in Ukraine.

ip.access’ solution will enable Proximus to deliver both coverage and capacity, exactly where it is required. Basestations will be positioned throughout the subway’s 38 below-ground stations, and will be connected back into the city’s above-ground mobile network to deliver ubiquitous coverage right across Kiev. The nanoBTS basestations are connected using optical fibre to the BSC. From there E1 links connect into the mobile cellular communication company UMC’s MSC.

“Working with ip.access, Proximus will be able to deliver an innovative solution to the issue of zero coverage in the underground system across Kiev,” says Yuri Nebosenko, General Director at Proximus L.L.C. “The underground has been a communications black spot for too long and nowadays commuters are demanding coverage wherever they are. The ip.access basestation enables us to provide this extended coverage without disruption and high prices for the Metro and mobile network operators. In the near future, Proximus will expand its underground network by installing additional ip.access basestations, thus enabling the use of dedicated radio-subsystems by each GSM operator in Kiev.”

ip.access will support Proximus both during and after the installation, providing technical assistance as the network is integrated into UMC’s network. The system will employ ip.access’ nanoBTS’s, nanoGSM BSC and Operations and Maintenance Center (OMC-R).

“ip.access is pleased to be a part of this innovative deployment with Proximus,” said Simon Albury, Business Development Director at ip.access. “This deal signals the first step to offering extended network coverage for cutting edge mobile technology and will provide an enhanced service experience for Kiev underground passengers.”
