The DCB-115 spread spectrum transceivers provide reliable long range data communications. Using frequency hopping spread technology, Free Wave transceivers are capable of uncompressed data rates of 115.2 Kbps over distances of 20 miles or more. As well as providing long range reliable data links, Free Wave transceivers set up quickly and incur no ongoing fees, unlike cellular and land line communications. Monthly telephone company costs are eliminated.

The DCB-115 transceivers operate point to point or point to multipoint, selectable using any async terminal program. Repeaters may be used to extend the range by programming the DCB-115 to operate as a store and forward unit. With up to two repeaters in a link and external antennas, links of 60 miles and beyond are possible.

Transceivers are assigned unique electronic serial numbers at the factory, providing control of who does and who does not have access to the data. An optional mode allows the transceiver to respond to a set of AT commands. Applications for the DCB series include:

Emergency back up links
Campus links for schools, colleges, manufacturing plants, offices
Home to office links
Computer to computer, terminal or multiplexer links
Lan to lan bridged and routed links
