RAD to Feature Hybrid Point-to-Point Wireless Multiplexer for Ethernet/IP and TDM Traffic

At ITU Telecom World 2003 in Geneva, RAD Data Communications will unveil a solution specifically designed for Western European applications for extending the range of services that may be provided over a given wireless link over point-to-point topologies.

 

The AirMux-106, which operates on Band B (5.47 to 5.725 GHz), is one of the first such systems available for the Western European market. It is a hybrid multiplexer that aggregates fractional E1 and Ethernet/IP traffic over a 2.6 Mbps full duplex wireless link, extending data/voice transmission up to 30 km. The product can transmit a full E1 (2 Mbps) of Ethernet traffic or a combination of fractional E1 and Ethernet using direct sequence spread spectrum (W-CDMA). The AirMux-106 conforms to the ETSI standard (EN 301 893) and supports Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC).

In most European Union member states, band B has been assigned for license-free transmission to supplement legacy 2.4 GHz license-free bands, which have become overly congested. Unlicensed frequencies allow faster and more affordable deployment since no coordination or license fee is required. “License-free bands are cost effective alternatives to leased lines,” explains Ramon Horkany, AirMux Product Line Manager at RAD Data Communications. “Since license fees do not exist, return on investment can be realised in less than a year.”

“The AirMux’s unique capability to transport both Ethernet/IP and TDM traffic over a wireless link reduces capital expenses by eliminating the need for an external multiplexer,” Horkany continues. “In addition, this capability makes the AirMux-106 ideal for a variety of applications, including the connection of LANs and PBXs at dispersed campus locations, the wireless backhauling of cellular base stations and deployment as a Wireless Local Loop solution.” License-free wireless bands are also commonly used for disaster recovery applications, as well as to connect temporary installations to the communications infrastructure.

The AirMux complements various RAD products to offer a complete solution. It can, for example, provide license-free wireless connectivity between sites at which other RAD products perform applications such as grooming, voice and data multiplexing, PBX extension or voice compression. Integrating equipment from one vendor enhances reliability of the solution and provides a single point of contact for the entire network. A single network management system simplifies management of the equipment, especially in large networks.

 

A version of the AirMux operating at 5.725–5.850 GHz, designed for North American and Eastern European applications, was launched earlier this year.
