"The WCS service rules effectively require 2.5 MHz of each block to be used for a guard band against interference," she said. "The 2.5 MHz of remaining spectrum in each block is not suitable for LTE or even HSPA, both of which require wider channels and paired spectrum.". Advanced Wireless Service 2 and AWS 3 and federal spectrum (60MHz). In January 2011 the NTIA said that it would evaluate the 1755-1850 MHz band of spectrum for commercial use. But so far, NTIA has not released information on the progress of this evaluation. And some in Washington blame the Defense Department for dragging its feet.

But public safety groups lobbied Congress to give them the entire 10MHz of wireless spectrum for free, so they could build their own network without allowing any of the spectrum to be used uag metropolis iphone xs max rugged wallet case - magma for commercial services, For more than a year, the D Block spectrum was engulfed in a political debate in Congress, Finally, a compromise was hashed out that would give public safety the spectrum and would even provide funds to build its network, Because the D Block is being considered as part of a larger spectrum auction package, the bill has not yet become law, That said, the most recent Payroll Tax compromise bill will include the D Block compromise and funding for the public safety network..

One thing to note is if the D Block is given to public safety, this means that 10MHz of prime 700MHz spectrum, which is already cleared and ready for use and would have been ideal for 4G LTE services, will not be used by commercial operators to help alleviate network congestion. In other words, another 10MHz of spectrum will be lost. Terrestrial Deployment of Mobile Satellite Spectrum (MSS) (90MHz). As a first step toward this goal, the FCC granted a waiver to the wireless broadband startup LightSquared in January 2011 on the condition that its network didn't interfere with other spectrum holders, namely GPS.

LightSquared was planning to use 40MHz of uag metropolis iphone xs max rugged wallet case - magma the total 90MHz the FCC had identified as possible wireless broadband spectrum in the satellite bands, LightSquared's network, which would have sold wholesale 4G LTE access to other carriers and retailers offering wireless services, would have covered more than 260 million consumers, And it would have offered another major competitor in a market that is dominated by AT&T and Verizon Wireless, LightSquared expected at least part of its network to be up and running in some regions of the country by the end of 2012..

But again politics intervened. Despite the fact that LightSquared and its predecessors have owned this wireless spectrum since 1989 and despite the fact that the FCC cleared the spectrum for terrestrial use in 2005, the GPS industry managed to kill the company's hopes of building its network, because it claimed the network would interfere with existing GPS devices. LightSquared offered concessions to mitigate the interference. But in a test conducted by the NTIA, results still showed interference. LightSquared said the tests were rigged and that the GPS industry selected out of date and obsolete equipment to be tested.
