Sounds to me like LightSpeed needs to make the adjustments. GPS was there first, and is used by critical systems. Which is not to say, if as LS claims, the GPS industry has been less discriminatory in it’s bandwidth tuning, that the GPS players don’t have work to do. But LS is the new player, and if there’s even a 1 in 10,000 chance that it might interfere with Nav/ILS systems (and I’m not talking Tom Tom), then, no go LS.
So you buy some property next to an existing one. You want to build a fence on the property line, but your neighbor complains that you can't do that because he had planted his garden five feet into your property. You have someone demanding that you curtail your use of your property because he didn't properly contain his activities to his own property.
