NTIA highlights just how bad LightSquared interference is
from DSL Reports
From July 12, 2011:
Late last month, LightSquared finally filed its revised testing report with the FCC, which unsurprisingly confirmed that its planned LTE network would significantly interfere with GPS signals. LightSquared recently proposed an alternate solution that would utilize a 10 MHz swath of L-band spectrum in the lower portion of the company's spectrum assets, instead of the chunk of 10 MHz spectrum they had planned to use but showed significant GPS issues.
