U.S. agency licenses through-the-earth communications technology
The Los Alamos National Laboratory Underground Radio technology is being commercialized by Vital Alert Technologies through two exclusive licensing agreements. The solution—originally developed for the Department of Energy—is a through-the-earth communications mechanism that uses low-frequency electromagnetic radiation and digital-audio-compression technology to wirelessly carry voice and data, according to the laboratory.
900-MHz radios support Iraqi communications network
Wireless Interactive used its Orion-900, 900-MHz radios capable of 22 Mb/s throughput as a wireless backbone for a communications network in Iraq that provides Internet access. The backbone is supported by the company’s RedFire-200, 2.4 GHz Wi-Fi products. Internet access has been problematic in the country because of a lack of wired infrastructure, making wireless the only option in many places. However, Wi-Fi congestion has made access difficult to achieve in some places, so the Orion-900 radios were deployed to fill the void, the company said.
