In addition to above, RailTel is also rolling out a broadband wireless access (BWA) network across India based on WiMax/Wi-Fi platform. RailTel has been allotted wireless frequency spectrum on 2.8 GHz band across 43 cities. 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. Other advantages include:

For other cities, the wireless network is being provisioned on the unlicensed band viz. 2.4 GHz & 5.8 GHz. The solution includes both point-to-point & point-to-multipoint access network depending upon the feasibility of the location.
