University of Bristol researchers presented two papers at the recent IEEE 2014 Wireless Communications and Networking Conference in Turkey that could significantly impact the future of mobile devices.
"We are fast running out of radio spectrum in the lower frequency bands where cellular and Wi-Fi currently operate," says Bristol professor Andrew Nix. "As a result, we need to exploit high frequencies in future products."
The first paper on gigabit wireless communications showed that polarimetric filtering can enable a higher density of active data links. Each millimeter wave link is capable of supporting user rates of up to 7 Gbps, with Bristol's research showing that four simultaneous links could be active in a single room, and these data capacities are 100 times better than those achieved with current Wi-Fi technologies.
The second paper proposes an efficient adaptive beam-forming algorithm to extend the range and data rate while also reducing interference. The paper used compressive sensing to significantly reduce the amount of control data needed to adapt a network to temporal and spatial changes in the channel.
