This new system will overcome bandwidth issues with the LightSquared service?
But it does seem to elude that current receivers may not be able to use the new system to it's fullest potential.
Block III adds new frequencies; new frequencies will require new receivers.
One of the slides from the recent Stanford conference showed the sensitivity and bandwidth of different GPS receivers, including older low-precision systems, modern high-precision systems, and combo systems that can use both (US) GPS and euro/russian signals.
When it comes to LightSquared, the GPS systems with the lowest sensitivity and narrowest bandwidth were the old, low precision systems!
The higher-precision systems, and the combo systems (for a variety of reasons) require larger bandwidth, making them more susceptible to LightSquared operation.
