4G Broadband May Jam GPS

Posted by CmdrTaco on from the jam-and-the-holograms dept.

mferrare noted some rumblings that 4G Broadband may jam GPS. There's a slew of technical bits in an report (PDF). 4G broadband frequencies (1525-1559MHz) are next door to GPS frequencies (1559-1610MHz). Test results won't be out until June.

  1. This just in... by Erich · · Score: 3, Insightful
    FM Radio could interfere with television broadcast channels 5 and 6, or aircraft navigation, since they're right next to each other!

    AM Radio could interfere with aircraft beacons, since they're right next to each other!

    Please. We've been allocating spectrum for things for a long time. Interference can be monitored and controlled. Do you really think that mobile telephone companies would put up with broadcasters puking all over their spectrum? Or vice versa? Or either putting up with amateur radio interference?

    Or, perhaps worst of all, do you think the Hams would put up with someone interfering with their spectrum? They can triangulate secret government projects accidentally using their shortwave spectrum.

    Yes, interference happens from all sorts of places. You'll likely find that devices in your adjacent spectrum are less likely to interfere than other sources of interference.

  2. Military use trumps all by CaseyB · · Score: 3, Insightful

    I would stress too much about this. Anything that has even a remote chance of interfering with the US military's use of GPS is never going to be deployed. Period.
