4G SYSTEM Vs GPS....OH Dear..!!

GARMIN SAYS 4G SYSTEM A THREAT TO GPS

Garmin is standing by its position that a proposal to build a network of 40,000 broadband transmission towers around the U.S. could severely disrupt GPS service. As we reported last week, LightSquared has received conditional FCC approval to install the massive system to carry 4G signals, the conditions being that it restrict its signals to their assigned frequencies on the L Band 1 (1525 MHz—1559 MHz) and test existing GPS devices to see what kind of interference the transmitters might cause. GPS uses the a frequency range of 1159-1610 MHz, which is right next to the LightSquared signal. Garmin's Jessica Myers told AVweb in a podcast interview that Garmin has done testing on its own and determined there's no practical way for the two systems to coexist.

Just for info.....

Quick scan of this article:

4G wireless is coming - NBN or not. But what is it, exactly?

"Government policymakers are considering the best policy for managing that bandwidth, but the process is complicated by the need to ‘stack’ existing allocated frequencies together. In late June, the government announced it will provide 126MHz of usable spectrum in the 700MHz band - between 694MHz and 820MHz - with spectrum auctions to run from late 2012. A decision on 2.5GHz spectrum, which can also be used for LTE, is expected soon; together, these decisions will pave the way towards a clearer, faster 4G future"

So, seems to be fairly clear of the GPS frequencies compared to the US allocations.
