摘要

The global satellite industry appears to have lost its exclusive use of part of the C-band radio spectrum that remains popular in equatorial regions but retained rights to the balance of spectrum coveted by terrestrial broadband networks. While no final decisions will be made until a Nov. 2-27 meeting of global governments at the World Radiocommunication Conference 2015 (WRC-15) in Geneva, it now appears many nations want to permit terrestrial broadband into the lowest part of the spectrum being contested. Given the publicized ambition of the GSM Association and other groups backing terrestrial wireless, the current state of affairs represents a modest victory at best. Having sought entry into the spectrum between 3.4 and 4.2 gigahertz, it appears that it will be limited to a 200-megahertz slice at 3.4 to 3.6 gigahertz. For the satellite industry the story is similarly mixed. Some industry officials even now are standing firm, saying the weeks remaining before WRC will be used to chip away at those backing terrestrial networks in the lower part of the band while holding on to gains between 3.6 and 4.2 gigahertz. In a statement issued Sept. 4 in response to SpaceNews queries, satellite fleet operator SES of Luxembourg said: "The lower C-band has been assigned to satellite for decades. Many operators are transmitting in these bands to customers who depend on that service. Losing that critical spectrum resource of course has an impact, which is why we defend it. Our strategy at WRC consequently has not changed: we defend the entire band."
