Japan’s National Institute of Information and Communications Technology (NICT) has successfully deployed mobile broadband communications systems at more than 40 Mbps throughput, and has successfully established a 3.7km link between two locations within the framework of the TV White Spaces Pilot organised by UK comms regulator Ofcom.
The trials of NICT systems have been deployed in central London where spectrum users such as TV broadcasters and active wireless microphone users need to be protected. NICT has also successfully developed a white space database which passed the qualification tests to be included in the Ofcom’s databases list.
This database provides protection from interference to the incumbents by calculating and providing information about available channels and maximum transmission power in each channel to the white space systems. NICT’s trial which deploys TV white space mobile broadband communications based on database information in a crowded city, is the first of its kind. The experiences obtained during the trials are expected to contribute to the development of TV white spaces regulations in the UK as well as other countries in the world.
NICT has successfully established the 3.7 km wireless link between two locations, and has successfully achieved more than 40 Mbps throughput for broadband mobile systems in the TV bands.
Based on the experiences and the results obtained from the trials, NICT plans to improve the performance of the devices and the database. NICT also expects to contribute these experiences to the development of white space relevant regulations in other countries, as well as to transfer its white space technologies to the stakeholders.
