The FCC is allowing T-Mobile USA to move forward with tests of an LTE service that would share spectrum with federal users in the 1755-1780 MHz band.
The 1755-1780 MHz band targeted by T-Mobile for testing were the focus of a bill released in April by two House lawmakers. The proposal gave federal agencies on the band five years to relocate to another block of spectrum, so that the FCC could pair the 1755-1780 and 2155-2180 MHz spectrum blocks and put them up for auction.
3GPP band 9 is 1750-1785 and 1845-1880 MHz
3GPP band 10 is 1710-1770 and 2110-2170 MHz
There is no such band in 3GPP plan which includes 1755-1780 and 2155-2180 MHz.
And if frequency sharing is good idea?
