SATEL XPRS RADIO ROUTER, QAM MODULATION
*SATEL XPRS radio router is designed for serial data connectivity in mission-critical applications. It is a part of SATEL XPRS solution for applications requiring long-range connections, high reliability and independence of network. It also provides an excellent technology for back-up routing: the intelligence to automatic switchover is included.
The SATEL XPRS radio router can be used as a serial data radio modem and as a repeater in packet routing networks. When central unit is added to the radio unit, full TCP/IP functionality is obtained. The SATEL XPRS IP radio router consists of two separate modules; a radio unit and a central unit. The central unit together with the radio unit is typically used in a network as a master station or in locations where Ethernet connectivity is needed.
For radio router stations, the central unit is not necessary. SATEL XPRS radio router can be used in stations where a standard RS-connection is sufficient. The radio unit can operate as a transparent radio link; essentially replacing a wire with classic RS-232 based protocol. Various network topologies, from a simple point-to-point link to long-range point-to-multipoint systems with multiple repeaters, are available with the radio unit.
