Lockheed Martin-built Air Force Milstar II satellite will be launched Sat. from Cape Canaveral aboard Titan IV launch vehicle during 4-hour window opening 2:09 p.m. ET. Satellite, designated F-4, has medium-data-rate (MDR) communications payload supplied by Boeing Satellite Systems for jam-resistant communications to U.S. forces. F-4, 4th of 6 spacecraft built by Lockheed Martin, uses 32-channel extremely high frequency uplink (44 GHz) and superhigh frequency downlink (20 GHz) to send real-time voice, video and data to military personnel at rate of 50 times faster than common PC modems.
SAN JOSE, Cal. - Telecom leaders need to develop regulatory strategy and regulators should become more flexible and less prescriptive, panelists said at Wireless Communications Assn. annual technology symposium here Wed. Regulators can help improve Internet broadband access and promote innovation by imposing regulations that are “technology-neutral,” said Industry Canada Spectrum Engineering Deputy Dir. Gen. Veena Rawat. Canadian regulatory agencies, she said, were moving away from “prescriptive, detailed technical standards” in favor of minimum constraints and only “essential technical rules.”
NTIA reported mixed results Thurs. in first round of ultra- wideband (UWB) tests in non-GPS band, pointing to “potential” to operate that wireless technology in 3-6 GHz range without interference. “The test results today show a great deal of promise between 3 and 6 GHz,” NTIA Dir. Gregory Rohde said at news briefing. But tests also found “difficulties” with interference in bands below 3 GHz, occupied by systems such as airport surveillance radar and federal govt. systems. Rohde said results set stage in coming weeks for negotiations between FCC and NTIA over final rule on UWB operation in GPS and non-GPS bands. Difficulties in bands below 3 GHz at certain distances between UWB devices and other systems could be mitigated through measures such as requiring devices in certain cases to operate indoors, Rohde said. “It’s not that a door has been closed here,” he said.
