    • Falcone is smoking crack if he thinks that...

      All LS has to do to reduce power (to the point of useless for cellular telecom)

    • There are several fundamental issues here.

      The first is whether the GPS receivers in fact rely on using spectrum that isn't assigned to them. The PC World article suggests that there is overwhelming data to demonstrate this is the case.

      Secondly is if LS or anyone spectrum holder should have the right to re-purpose spectrum they own for a different service type. If the FCC does not uphold a spectrum holder's right to use their spectrum as desired there will be little hope of the modernization of existing spectrum to serve the future wireless needs of U.S citizens.

      That the defense or public safety community may rely on GPS gear that is improperly built does not alter the fact that they are transgressing on spectrum that belongs to others (if in fact the data shows they are). Reversing this error may require some time for the GPS industry to correct the problem and get new equipment to users, but the FCC cannot simply ignore the situation. They must identify which parties are operating within the law and which are not.

      LS is within their right to get the FCC on record regarding the facts of the case, and they may deserve compensation from those that have harmed their ability to utilize the spectrum they own.

      • If you buy land zoned residential you have the right to request a zoning change to build apartments. But the neighbors have the right to complain that it will interfere with traffic patterns. If the zoning board therefor denies your request, you still have the right to use the land for residential, but you don't have the right to sue the zoning board or neighbors because you couldn't build apartments.

      • Excellent post mega.

        LS2 may have pursued the use of the nearby adjoining MSS-GPS band with inadequate foresight and not taken aspects of their design, such as earlier work to clear problems of selected precision GPS use within the MSS band , but they have come around and taken several steps to circumvent their own, and GPS imposed problems of interference.

        -Exactly right. Anyone who has worked with the defense and aerospace industries know that they rely heavily on specifications that mandate how the equipment is supposed to perform, often including very stringent requirements for RFI/EMI. That stems from the critical nature of the applications and evolution of the organizations that come to deal with a high-spec environment. I worked in the mil-aero electronics equipment environment including work on getting stuff approved and through rigorous testing, ie. RFI/EMI labs testing work. And i represented a Japanese RFI test gear supplier for a while. Despite that, the industry, particularly the military and FAA/TSB does stuff that is out of line because they rely on their suppliers for blanket spec requirements... for them to be the experts in their chosen field. The GPS industry, imo, has not adhered to FCC and DoD guidelines or simple 'sound design practices' for use of adjacent spectrum. While their goals may appear laudable, the reality is that the industry has violated basic mandates and ignored potential advances that would have furthered their field while making more harmonious and 'future proof' use of technology.

        "Kick the bums in the nuts! The lying, thieving scum bags! (GPS scounds)" - just aiming to rile up the idiot horde.

    • However, the article seems to entirely miss the major hurdle - Department of Defense concerns. I won't argue who has the signal spilling blame or cross-over. The fact is there is a conflict with the signals and it amounts to a matter of national security that is not going away overnight. Right or wrong faces overriding pragmatic facts. Now is now, the future is tomorrow, and it seems somebody can't wait that long.

      It is also crying over spilled milk when you buy spectrum for one purpose and then years later try to use it in a different configuration. It will turn out to be like the sunshine laws, build what you want but don't block your neighbor's reception of sunlight. Well, almost but that's the idea generally.

    • Will see very soon where this ends but they are desperate and resorting to demands. The govt will wear them down.

    • Thanks
