Background on GPS Issues

• LightSquared, responding to issues raised by the GPS industry, agreed to

stringent emissions limits on its operations (2002-2003)

• These emissions limits, stronger than for any other commercial wireless

carrier, ensure LightSquared’s signal does not travel outside of its own spectrum band

• It turns out, however, that many GPS devices are designed to receive signals
• utside of the GPS spectrum band and within the adjacent band licensed to

LightSquared

• After this issue was first raised in late 2010, the FCC directed LightSquared to

form a working group to study GPS issue

• Working group included LightSquared, GPS manufacturers, federal agencies

and representatives from various user communities

• 130 different GPS devices were tested in a variety of spectrum configurations,

including the configuration later proposed by LightSquared in its mitigation plan

Testing has Provided Information Essential to Finding Solutions

• Many devices did show affects when tested against LightSquared’s initial

deployment plan

• As a result, LightSquared has significantly revised its deployment plan
• Testing identified power levels and frequency combinations at which devices

were most susceptible

• LightSquared’s revised deployment plan is specifically tailored to ensure

narrowband GPS devices will not be degraded by LightSquared’s operation

• New Channel Configuration
• Drastically Lower Power Levels
• Commitment to Specific On-The-Ground Power Levels to Eliminate any Uncertainty
• LightSquared has also funded the development of the necessary filters to

allow wide-band devices to be adapted to eliminate any potential incompatibility going forward

• The Federal Government is undertaking further testing to validate the

effectiveness of LightSquared’s mitigation steps

• LightSquared is fully cooperating with this testing
• Results to be released by November 30

Conclusion

• LightSquared’s integrated satellite and terrestrial network will bring great

benefits to wireless users nationwide

• We are committed to ensuring that there is no disruption to GPS users as a

result of our deployment

• We are eager to work through the remaining issues so that this network

deployment is not further delayed

• We remain committed to working with the utmost transparency and in good

faith to ensure that any reasonable concerns are appropriately addressed
