Exalt Communications this week released the EX-r 5 GHz radios to meet the needs of public-safety users who demand high throughput and reliable backhaul connectivity, said Amir Zoufonoun, the company’s CEO.

The EX-r was developed to meet the needs of next-generation applications in the microwave backhaul arena and can act as the backbone for any communications system that connects to other communication hardware, such as two-way radios, Zoufonoun said. It is a tri-band radio that includes all three 5 GHz bands in one ruggedized enclosure. It offers a software-controllable channel bandwidth and built-in spectrum analyzer, which lets the device operate on frequencies from 5.2 GHz to 5.8 GHz. In addition, it provides 440 Mp/s aggregate user-available throughput and AES 128 and 256-bit encryption for secure communications.

“So the user has lots of choices of frequencies, and with the built-in spectrum analyzer in the product, the user working remotely from anywhere in world can look at any node, any radio and find the quietest spot—through an RF environment point of view—and park the signal in the quietest spot,” Zoufonoun said.

The ruggedized enclosure protects internal electronics from 40 to +65 ambient temperature, as well as against lighting strikes and dust and water. It is powered by power over Ethernet.

“That’s the only connection a user needs for the device—one cable coming down from the rooftop or tower into the switch or router,” he said.

The radios start at $20,000.
