SINGAPORE Singapore's communications regulator has issued new regulations governing the use of ultrawideband (UWB) technology in the city-state.
Brushing aside some industry concerns that UWB devices could interfere with existing mobile and broadcasting networks, the Infocomm Development Authority (IDA) said any devices complying with its technical and emission standards would be exempt from licensing requirements to allow "keen industry players to develop and commercialize [UWB] with greater ease."
The authority has allotted the 3,400- to 10,600-MHz spectrum bands and set an emissions cap of -70 dBm/MHz for most UWB applications, though it noted that devices exceeding those limits could be used in Singapore with IDA approval "on a case-by-case basis."
While some operators had called for tighter controls on UWB technology, the IDA argued its approach was similar to those adopted in the United States, Europe and Japan. The authority said it had no reason to believe UWB devices would degrade mobile services.
The regulator also turned down requests to specify a list of locations where UWB could be used, saying it would be "impractical to produce such an exhaustive list," but it did promise to investigate and "take appropriate measures to resolve" any cases where UWB interfered with other transmission systems.
Hoping to establish Singapore as a testbed for commercial UWB applications, the IDA has been fleshing out a regulatory framework for the technology since 2003. Its new regulations are expected to be formally adopted and instituted by the end of the year.
