The Dynamic Spectrum Alliance, a group pushing governments for more open access to wireless spectrum, said Monday it is holding its first-ever global summit in Bangkok. Membership in the group, which launched in June, includes technology firms such as Microsoft Corp., Google Inc. and Facebook Inc. It calls on governments around the world to provide more access to spectrum, saying in a release that an “artificial sense of scarcity” of spectrum exists due to tight regulations. “The diversity of our membership demonstrates strong support throughout the industry for more efficient and effective spectrum utilization,” Alan Norman, of Google’s access strategy group, said in the press release. “The policies we’re promoting wouldn’t just create an advantage for one company or another, but rather would benefit consumers and businesses alike on a global scale.” Some of the Canadian members of the alliance include Ottawa-based 6Harmonics Inc. and Canadian Spectrum Policy Research. A separate release from Microsoft last week said TV white spaces were used for communications during relief efforts for the 7.1 earthquake that hit the Philippines on Oct. 15, and after typhoon Haiyan struck on Nov. 8.
