Exalt Introduces 5 GHz Microwave Backhaul Radio

Exalt Communications introduced its EX-r GigE series of microwave radios, covering all three 5 GHz bands in a single carrier-class system and featuring native Ethernet and native TDM support integrated in a single system.

Exalt said its new EX-r GigE series microwave platform provides sufficient capacity and resiliency to allow wireless operators, enterprises and broadcasters to deliver the bandwidth they need for campus connectivity, camera backhaul, 3G or 4G backhaul, WiMAX backhaul, and high-definition video broadcast. The GigE series delivers 440 Mbps aggregate throughput at link ranges of up to 15 miles with guaranteed five 9s (99.999 percent) availability. By contrast, weather sensitive radios operating in the 60 to 80 GHz bands are typically limited to a range of one to three miles.

The EX-r GigE radios are available in two versions, offering maximum deployment flexibility. The EX-5r GigE features a high performance integrated antenna, while the EX-5r-c GigE includes type-N female connectors for flexible external antenna mounting. Along with native Ethernet, the EX-5r and EX-5r-c provide up to four T1/E1 ports. Exalt also provides proprietary link security and integrated AES 128- and 256-bit encryption.

The EX-r GigE series also features an 80:20 traffic symmetry control that can be used to accommodate highly asymmetric traffic such as video surveillance, broadcast, and storage backup. In addition, the EX-r GigE series provides the ability to remotely upgrade and manage the radios, user-selectable bandwidth and modulation, low latency, and advanced interference avoidance with spectral efficiency, tuning resolution, spectrum management, and system collocation.

"Oddly enough, today's wireless operators and enterprises find themselves in a similar predicament; both face a severe bandwidth crunch in their transport networks that cannot be economically solved with leased lines or fiber," stated Amir Zoufounoun, president and CEO of Exalt Communications. "As network capacity demands continue to accelerate, both groups need scalable lower-cost alternatives to leased lines that can accommodate high throughput for multiple applications. They also need a flexible platform that includes license-exempt products so that they can deploy these services quickly, reliably and easily."
