General Description

The AirPro^® S-Band digital microwave radio provides solutions for voice and data applications between two locations up to 30 miles (50 km) apart. A pair of AirPro radios with line-of-sight access creates a robust wireless link using spread-spectrum microwave transmission. 

This technology delivers very low bit error rate links that have high immunity to interference. These links are ideal for public and private networks. Applications include Wireless Local Loop (WLL), Wide Area Networking (WAN), and Metropolitan Area Networking (MAN). High-performance links are ideal for frame relay applications and last-mile feeders into optical and satellite networks. 

The AirPro family has advanced network management features including software configuration with extensive Built-In Test Equipment (BITE), and remote control of far-end units over the microwave links. These features help large network providers administer and maintain networks for maximum service levels.

Point-to-Point Applications
 

In a point-to-point system (as shown above), two AirPro® S-Band digital microwave radios establish a link connecting computers, LANs, voice/data multiplexers, and other digital communication devices. The point-to-point topology can be expanded to a “star” configuration using multiple point-to-point links converging at a central hub site. In a point-to-multipoint system, the AirPro® S-Band radios provide a link between a host computer and two or more remote computer devices. The remote devices are controlled by the central host with a poll-select communication protocol that is transparent to the radios.
