WiMax backhaul

WiMAX is a telecommunications protocol that provides fixed and mobile Internet access. The current WiMAX revision provides up to 40 Mbps with the IEEE 802.16m update expected to offer up to 1 Gbps fixed speeds.

The bandwidth and range of WiMAX make it suitable for the following applications:

• Providing portable mobile broadband connectivity through a variety of devices.
• Providing a wireless alternative to cable and DSL for “last mile” broadband access.
• Providing data, telecommunications and IPTV services.
• Providing a source of Internet connectivity as part of a business continuity plan.

For the delivery of WiMax services, WiMax base stations require connectivity to Internet backbone. It can be supplied via fiber or point to point microwave radios. The latter ones provide sufficiently high capacity, which enables to aggregage data from several WiMax base stations, as well as lengthy hops, which is suitable for the network topology for remote areas. Prohibitively high trenching costs and time required for fiber installations provide microwave radios with clear competitive advantage.

For WiMax backhaul infrastructure, Modesat offers Ethernet radio modem IPs, which are designed keeping in mind the requirements posed by ASPs.
