About

Background: This software, called Glia, enables Wi-Fi networks to operate at an optimal data rate, improving data throughput and therefore the performance of applications requiring high bandwidths. This improvement to wireless data throughput can reduce the bandwidth gap between wireless and wired data networks.This software-only solution allows the multiple radios in a Wi-Fi array to act as one single radio, occupying all the channels at the same time and achieving their optimal, aggregated transmission rate.Glia can optimize long- or short-range data transmission to improve data throughput for enterprise network deployments, wireless backhaul for wireless mesh networks, wireless video delivery networks for home or office, and other similar high-bandwidth applications.The software works with any off-the-shelf Wi-Fi radios, requiring minimal or no changes to their hardware or firmware. Glia is backwards compatible and can be implemented in existing Wi-Fi network environments, as well as with new deployments.The Glia software combines the multiple orthogonal channels in a Wi-Fi array to achieve an optimal aggregate data transmission rate. For example, a 15-channel Wi-Fi network array with three channels in the 2.4 GHz band and 12 channels in the 5 GHz band could theoretically achieve a data rate of 600 megabits per second (Mbps). However, experiments have shown a combined performance of only 91 Mbps.This mediocre performance can be attributed to the close physical proximity of the radios on the Wi-Fi array, specifically out-of-band emission of energy and filter inefficiencies.Glia overcomes these problems by coordinating the different radios on a Wi-Fi array and delivering the aggregate data-rate expected from the array. The software uses a combination of medium access, scheduling, framing, and channel management mechanisms to allow the radios on the Wi-Fi array to use all orthogonal channels effectively.
