40. Other Frequencies. We invite commenters to propose any other band that would meet the Spectrum Act's requirement for the Commission to identify 15 contiguous megahertz of spectrum. We encourage commenters to identify specific bands, to explain what the band is currently used for, and how it might be allocated and transitioned for commercial use under flexible use service rules for operations such as wireless broadband service.
41. Base vs. Mobile Transmissions. As discussed further below, we propose to allow the use of each AWS-3 band in a manner that is compatible with the use of adjacent bands. Doing so reduces the risk of harmful interference to co-channel or adjacent band operations or the need for highly restrictive technical limits that would leave some AWS-3 spectrum underutilized. We believe our band-use proposals maximize the potential usability of these bands. We seek comment on our proposals and invite commenters to propose alternatives.
42. Base Transmit. In 2008, the Commission proposed to allow base and mobile operations in the 2155-2180 MHz band to support Time Division Duplex (TDD) operations. To protect base operations in the adjacent AWS-1 band from harmful interference due to mobile operations in the AWS-3 band, strict power and out-of-band-emission (OOBE) limits were placed on AWS-3 mobiles. These measures included a slightly lower than normal mobile power limit and a mobile
43. Unlike AWS-4, here we have the option to avoid designating uplink next to downlink, which in turn avoids the need for guard bands or significant technical limits that mitigate interference between uplink and downlink. As we recently concluded in connection with AWS-4, having mobiles (or base and mobile TDD transmissions) requires significant power reductions and
