Military use aside, Ka-band must be seen as more than just a frequency, as spotbeams, phased array antennas and new software technologies entering the picture. Because the hype is gone and the mood is more cautious, yet optimistic nonetheless, there is no real audience for any wild-eyed projections. Most if not all of the early backers with their deep pockets also are gone. With more than 80 Ka-band geostationary orbital slots assigned to U.S. operators by the FCC, and with almost 50 active licenses assigned in two rounds, there is simply not enough space here to update the status of all the Ka-band ventures, both geostationary and non-geostationary systems. Still, look at all the recent and quite unexpected developments. EchoStar Communications Corp.'s decision to acquire Ka-band capacity on SES Americom's AMC 15, and Liberty Media Corp., Intelsat Inc. and the National Rural Telecommunications Cooperative (NRTC)'s decision to invest in CO-based Wildblue Communications are signs of forward momentum adapted to the new realities of the broadband arena. Besides obtaining a stake in Wildblue, Liberty Media reached an agreement with Lockheed Martin Corp., Northrop Grumman Space and Mission Systems Corp. (formerly TRW Inc.) and Telespazio S.p.A. involving a proposed restructuring of Astrolink International LLC. Liberty Satellite will acquire substantially all of the assets of Astrolink, which is scheduled to initiate service in late 2005, while the two satellites for Astrolink are simultaneously back on track at Lockheed Martin and Northrop Grumman.
