Possible MSS Allocations (WRC-15 Agenda Item 1.10)

Agenda item 1.10 of the 2015 World Radiocommunication Conference:

"to consider spectrum requirements and possible additional spectrum allocations for the mobile-satellite service in the Earth-to-space and space-to-Earth directions, including the satellite component for broadband applications, including International Mobile Telecommunications (IMT), within the frequency range 22 GHz to 26 GHz, in accordance with Resolution 234 (WRC-12)"
