Indian telco Tata Communications has announced that it has selected WiMAX vendor Telsima to provide WiMAX solutions for a planned nationwide network. The Indian telco will be investing around USD500 million in the project by the end of 2010, and expects 200,000 WiMAX subscribers by March 2009. The project aims to roll out the largest WiMAX network in India, with coverage of 110 cities for the enterprise segment, and 15 for retail with Telsima deploying around 3,000 base stations. The initial phase is to extend wireless broadband internet access, already available in Bangalore since July 2007, to a total of nine cities; Delhi, Mumbai, Pune, Bangalore, Chennai, Hyderabad, Cochin, Chandigarh, and Kolkata, rising to 15 by the end of 2008.telegeography.com
Mobile WiMAX Base Stations
Macro Base Stations are designed for use in high performing cells that are able to handle several thousands of users supporting a rich set of features. The Integrated BS and Pico-cell BS offer fewer features at lower cost – ideal for less dense deployments or to fill-in under-served spots. StarMAX 6400 Mobile WiMAX Macro Base Station
The Telsima Mobile WiMAX Architecture
The Telsima StarMAX 6000 family is based on the Telsima base station architecture for Mobile WiMAX BS. Its scaleable blade architecture gives room to deliver the performance required for Mobile WiMAX infrastructure with MIMO and beam forming technologies and is capable of supporting triple play services in upcoming mobile 4G environments.

Mobility Support
Mobility in Mobile WiMAX is enabled by information sharing between Mobile Station, Base Station and ASN infrastructure.
Telsima base stations support the standard mechanisms of base station-initiated hand-off as well as the enhanced mode of Mobile Station initiated hand-offs. In the enhanced mode, it is ensured that the mobile station scans and informs all the involved infrastructure about its preferred base station. The BS and ASN infrastructure then manage the hand off accordingly.
