The NTIA has told the FCC that several federal agencies including Homeland Security are concerned that LightSquared's satellite-terrestrial LTE network will interfere with government communications services.
In a Jan. 12 letter to the FCC, NTIA chief Lawrence Strickling said that LightSquared's hybrid mobile broadband services raise "significant interference concerns."
"Grant of the LightSquared waiver would create a new interference environment and it is incumbent on the FCC to deal with the resulting interference issues before any interference occurs," Strickling wrote. "Several federal agencies with vital concerns about this spectrum band, including the Departments of Defense, Transportation and Homeland Security, have informed NTIA that they believe the FCC should defer action on the LightSquared waiver until these interference concerns are satisfactorily addressed."
LightSquared wants the FCC to issue a waiver that would let it offer terrestrial-only LTE services on its satellite spectrum. NTIA wants the FCC to defer that waiver until the interference concerns from the federal agencies are addressed. Strickling asked the FCC to work to ensure that LightSquared's services do not affect federal communications services such as GPS receivers, maritime and aeronautical emergency communication systems, and Inmarsat receivers.
