RailTel has fiber access network in major important cities across the country. To enable services to customers, most of the commercials hubs within these cities have been connected with backbone network.

RailTel is also rolling out a broadband wireless access (BWA) network in select cities by deploying WiMax/Wi-Fi platform.

BWA is a standards-based WiMax (Worldwide Interoperability of Microwave Access) technology for "last mile" solutions that can connect customers to the RailTel ISP/ MPLS POPs through high-speed wireless access.

Typical Broadband Wireless Access (BWA) system is composed of two key elements- base station and subscriber equipment. The base station connects to the subscriber equipment using an outdoor antenna to send and receive high speed data to subscriber equipment, thereby eliminating the need of wire line infrastructure and provides flexible and cost effective last mile solution.
