High-Gain Patch Antennas Boost Wi-Fi Capacity In Crowded Lecture Halls

An anonymous reader writes "To boost its Wi-Fi capacity in packed lecture halls, Georgia Institute of Technology gave up trying to cram in more access points with conventional omni-directional antennas, and juggle power settings and channel plans. Instead, it turned to new high-gain directional antennas. They look almost exactly like the bottom half of a small pizza box, and focus the Wi-Fi signal from the ceiling-mounted access point in a precise cone-shaped pattern, covering part of the lecture hall floor. Instead of the flaky, laggy connections, about which professors had been complaining, users now consistently get up to 144Mbps (if they have 802.11n client radios). 'Overall, the system performed much better' with the new antennas, says William Lawrence, IT project manager principal with the university's academic and research technologies group. 'And there was a much more even distribution of clients across the room's access points.'"

    Hey Grandpa, is that you?

    It is hardly newsworthy that a group of IT network techs 'fixed' their coverage and performance problems using directional antenna technology.
    Radio techs have been doing exactly that since they learnt about propagation.

    so... does this mean you aren't interested in the story about how they replaced the batteries in the remote?
