DARPA Continues Work on 100 Gigabit-Per-Second Wireless Communications Systems Development

wireless-communicationsDefense Advanced Research Projects Agency researchers have began to develop a 100-gigabit-per-second wireless communications system and will continue further development and testing within the next year, C4ISR & Networks reported Friday.

Adam Stone writes the 100G program looks to position networking assets at altitudes of around 60,000 feet and distribute the network at ranges of 124 miles air-to-air and 62 miles air-to-ground.

Researchers aim to utilize higher-order modulation, to boost efficient use of bandwidth, as well as line-of-sight spatial multiplexing in a push to fully achieve 100G functionality.

“100G attempts to provide the capacity traditionally associated with fixed infrastructure, such as fiber networks, with the mobility we traditionally associate with wireless systems,” said Ted Woodward, manager for the 100G program.

“We specifically invested in high-order modulation and spatial multiplexing methods early in the program because the current state-of-the-art did not readily support our needs.”

The second phase of the 100G program has begun and it will aim to integrate various technologies that have passed muster to develop a new system.
