In this paper, we present the world’s first prototype of the IEEE 802.11af-based baseband (BB) integrated circuit (IC) enabling compact, low power consumption and even low cost TV white-space (TVWS) devices. Although it has been already over three years since the IEEE 802.11af was standardized in December 2013 as a wireless local area network (WLAN) system utilizing the TVWS, the IEEE 802.11af-based...
Since the FCC stated a policy on unlicensed use of the TV white-spaces (TVWS) in November 2008, a number of countries and regions have studied utilization of the TVWS, and some communication systems using the TVWS have been globally discussed and standardized. It has been three years since the IEEE 802.11af has been standardized, while the IEEE 802.11af-based system is not yet applied for commercial...
TV White Spaces (TVWS) technology allows wireless devices to opportunistically use locally-available TV channels enabled by a geolocation database. The UK regulator Ofcom has initiated a pilot of TVWS technology in the UK. This paper concerns a large- scale series of trials under that pilot. The purposes are to test aspects of white space technology, including the white space device and geolocation...
Utilization of the TV white-spaces (TVWS), which are spatially or temporally unused frequency in TV bands, is promising technology to alleviate spectrum resource shortage. Services using the TVWS have been already started in the U.S.A., and the TVWS pilot program has been performed and test operation of qualified white-spaces database (WSDB) has been started by the Ofcom in the U.K. Authors have developed...
Recently, a spectrum resource shortage problem has been aggravated in a cellular system due to growth of service or application business based on high-speed and high-capacity communication. To solve this problem, data traffic offloading to “white-spaces” has been promoted worldwide. In particular, white-spaces in the TV band (TVWS, TV White-spaces) has attracted attentions for securing more channels...
