Intel Gives WiFi A Big Boost

from the just-a-little-further dept

Some researchers at Intel say they've devised a way to send WiFi signals up to 100 kilometers (via Broadband Reports) using standard equipment, compared to the few hundred feet they can normally travel. Their system uses directional antennas and special software to do the trick, and it's intended to be used in developing nations to provide remote areas with internet access. Typically, WiFi signals are sent over a circular area, with the router in the middle. It's possible to focus the signal, using a directional antenna, in a particular direction, and use power just to send the signal that way, instead of all around. That's not really any secret or breakthrough, but it sounds like the Intel researchers' real innovation is in creating a system that electrically steers the antennas on both ends of the connection, automating what can be a particularly difficult task. While it's being suggested that this technology could replace WiMAX -- hence Intel's apparent lack of interest in rolling it out in the developed world -- this directional requirement makes this souped-up WiFi unsuitable for much more than backhauling other types of connections, particularly since it wouldn't be able to support multiple simultaneous connections. For instance, it could be used to send a net connection to a remote village, where standard WiFi gear could be used to share the connection locally. The advance here isn't in creating a potential competitor to WiMAX or other mobile broadband technologies; the innovation is in creating a solution to the problem of aligning directional antennas, which could potentially be applied to other wireless technologies beyond WiFi.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support.

    couldn't have been that hard

    come on, i've been mind-toying with an algorithm for aligning antennae (or solar collectors) for quite some time.

    1. measure current signal
    2. measure signal at -1E direction
    3. measure signal at -1W direction
    4. measure signal at -1N(or up) direction
    5. Measure signal at -1S(or down) direction
    6. move in direction of greatest signal.
    7. repeat until

    add more directions (nw, sw) for more accurate directional movement...

    *claps*

    that seems like an undergrad algorithms class assignment.. not an "intel, king of chipdom" "breakthrough".

    i'd say it's not news, but maybe the real story is it took this long for them to do it
