PSW Staff 01/15/09 09:03 PM, 0 CommentsToday at Winter NAMM’09, AKG launched the DMS 700 digital wireless microphone system, offering digital audio encryption, ultra wide tuning range and high channel count in 19-inch chassis. The DMS 700 operates with two frequency bands with each band providing a tuning range of up to 155 MHz of receivers and transmitters giving the user extended flexibility in today’s crowded RF environment. The clean digital audio transmission eliminates the distortion and significant noise levels at the higher audio frequencies that… View this story

Christopher Lyons 01/08/09 04:48 PM,In November, the Federal Communications Commission released the full text of its Second Report and Order approving the use of the “white spaces” – the TV channels that are not actually occupied by a broadcast station – by unlicensed consumer wireless devices. The FCC now refers to these as “TV Band Devices” or “TVBD’s”. The 130-page document provides details of the technical, operational, and regulatory requirements that the new devices will be subject to. The FCC’s attention to the needs… View this story

Wednesday, November 05, 200811/05/08 09:53 AM, 0 CommentsThe Federal Communications Commission voted Tuesday (November 4) to allow technology companies like Google, Microsoft, Dell, and Motorola to produce “white spaces” devices that will use the same radio frequency (RF) spectrum now being used by wireless microphone systems. Final text of the rules is not yet available, but the order is purported to greatly reduce the amount of clear spectrum available for use by professional audio and communications equipment. The Commission adopted certain important elements of Shure’s recent wireless… View this story

PSW Staff 11/03/08 01:08 PM, 0 CommentsBroadcast groups and networks have filed an Emergency Request with the FCC urging the agency to follow its own standard practice and seek comment on a technical report released last week by the Commission’s Office of Engineering and Technology. The report, which details interference test data for several prototype ‘white space’ devices, contains findings conclusively demonstrating that unlicensed devices relying solely on spectrum sensing threaten the viability of clear TV reception. “Simply put, until two days ago, it has been… View this story

Tuesday, October 28, 2008PSW Staff 10/28/08 01:16 PM, 0 CommentsShure has delivered a new, alternative White Spaces Proposal to the Federal Communications Commission (FCC) regarding Docket 04‐186. In a company communication issued late yesterday (October 16, 2008), the company stated, “The time is now for anyone interested in the future of quality professional wireless audio to communicate to all of the FCC Commissioners that the Shure proposal is the minimum acceptable proposal to continue their operations without serious disruption. “The FCC Test Report has been released and a vote… View this story

Wednesday, October 01, 2008PSW Staff 10/01/08 01:21 PM, 0 CommentsIn a letter to FCC Chairman Kevin Martin, NSCA Executive Director Chuck Wilson expressed concern regarding white spaces proceedings and new television bandwidth devices. As recently as August 9, the FCC conducted a test of white spaces devices before and during a Buffalo Bills-Washington Redskins game in Washington D.C. The results showed that the prototypes did not accurately sense wireless microphone signals, a function that would be required to prevent interference. “Our members are alarmed by preliminary public reports about… View this story

Monday, January 28, 2008PSW Staff 01/28/08 01:42 PM, 0 CommentsThe Commission’s Office of Engineering and Technology (OET) announces that it will begin a second phase of laboratory bench testing on the performance of prototype television white space devices on January 24, 2008. The second phase of testing (Phase II) will be conducted openly and transparently. This testing is part of a proceeding to consider authorizing the operation of new, low power devices in the television (TV) broadcast spectrum at locations where channels are not being used for authorized services.… View this story
