RAD: RAD enters wireless market with new 5.X GHz point-to-point



Mar 13, 2003 (M2 PRESSWIRE via COMTEX) -- RAD Data Communications has entered the wireless market with the launch of its new AirMux-104 TDM and Ethernet multiplexer at CeBIT 2003 in Hanover, Germany.

The AirMux-104 is a point-to-point multiplexer aggregating E1 and Ethernet traffic over a 2.6 Mbps full duplex link, extending data/voice transmission up to 16 kilometers (10 miles). The product can transmit Ethernet or E1 traffic, or a combination of fractional E1 and Ethernet traffic, using direct sequence spread spectrum (W-CDMA), which also enhances security.

Ideal For Campus Applications and Wireless Cellular Backhauling

"The unique capabilities of the AirMux in transporting both Ethernet/IP and TDM traffic over a wireless link make it an ideal solution for a variety of applications," states Ramon Horkany, Product Line Manager at RAD Data Communications. "These include connecting LANs and PBXs at dispersed campus locations and wireless backhauling of cellular base stations, in addition to deployment in a wireless local loop environment," he explains. The AirMux is fully synergetic with other existing RAD product solutions for private networks and campus applications, and can be used in tandem with them.

Unlicensed Frequency Allows For Fast, Affordable Deployment

The AirMux-104 operates at a frequency of 5.725 to 5.825 GHz, which, in many countries in Eastern Europe, the Mediterranean, the Far East and the Americas, is an unlicensed frequency. "This allows for fast, affordable deployment, since no frequency coordination and licensing fees are required," Horkany notes. In addition, this frequency enables a high quality of service because it generally is not affected by harsh weather conditions such as fog and heavy rains, nor does it suffer from frequency congestion like legacy 2.4 GHz bands. Powerful forward error correction (FEC) ensures high reliability and QoS. Another version, operating at 5.4 to 5.725 Ghz that will target Western European applications, will be rolled out at the beginning of Q3.

The device also employs Time Division Duplex (TDD) technology, allowing for bi-directional traffic flow on a single channel, eliminating the requirement to allocate pairs of channels for the uplink and the downlink, simplifying the installation procedure. Enhanced tools for providing a high quality of service are provided via monitoring tools for TDM and radio links.
