I think I must write one of these items a week. There's more concern about the new wireless network. This time, it's the Pentagon. The Defense Department and federal transportation officials have sent the FCC a letter voicing their concerns about the network, saying the network will cause major GPS issues - GPS not only helps you find the restaurant you'll have dinner at, but it's also a national security issue. LightSquared responded with this: "We are sensitive to concerns about potential interference, which is why we have fully committed ourselves to a comprehensive process that will ensure our network can coexist with GPS devices and agreed to only launch commercial operations when this process is completed to the FCC's satisfaction." The FCC also said in response to the letter that "LightSquared will not be permitted to move forward with service under the waiver until potential interference issues are addressed."
