Unlicensed frequencies called “white space” make up the uncharted territory of the television broadcast range. The Federal Communications Commission (Federal Communications Commission) has proposed starting white space to the public for mobile systems. The release of white space unlocks huge possibility of wireless networks. Some are calling the emerging technology “Wi-Fi on steroids. White space wireless will enable supercharged networks that could end hunting for a Wi-Fi hot spot forever. Gadgets with capabilities not a soul has thought of yet will be made possible by Wi-Fi on steroids. The economic potential of having the white space range available without a license for smaller businesses is projected to be within the billions.
Exactly how white space will power innovation
The Federal Communications Commission has been formulating white space policy for a while. An announcement on the agency’s future plans is expected Sept. 23. A New York Times article regarding Wi-Fi on steroids said that white space became available when the conversion from analog to electronic digital broadcast created a greater unused portion of the TV broadcast spectrum. Digital transmission uses a narrower band of the television broadcast spectrum, creating more white space around each broadcast signal. Wireless technology developers are excited about white space. Wi-Fi on the lower frequency of the Television spectrum could have far greater range, penetrate barriers more very easily and provide more dependable Web access . By making the white space spectrum accessible free of charge, the Federal Communications Commission could start a technological movement the exact same way it did in 1985, when starting unlicensed range led to Television remotes, garage door ! openers and today’s wireless systems.
Can super-charged Wi-Fi cause difficulties?
Reaction to the wireless potential of white space has not been entirely good. PC World reports that broadcast television networks and businesses using mobile microphones, for instance theaters and sports arenas, have opposed the liberation of white space. The concern is that wireless networks with a range of several miles, instead of various yards, will interfere with their signal. However, to keep devices using the white space spectrum from interfering, the FCC has created a database of Television channels and wireless microphone usage. Devices would need to be configured to stay away from the frequencies being used in a given area.
White space networks tested
Wi-Fi on steroids using the white-space spectrum is being tested in a number of locations. The Register reports that Microsoft has installed a white space network on its campus in Redmond, Wash. Microsoft’s network, dubbed “white-fi,” uses just two hot spots allowing users Internet access on shuttles and offices throughout its 500-acre campus. The Times white space report highlights super Wi-Fi in New Hanover County, N.C.. Remote cameras connected through white space keep an eye on traffic patterns for the transportation department. Without the expense of sending workers into the field, the parks department meets federal needs by collecting and transmitting environmental information . Other breakthroughs to expect within the future could possibly be remote medical networks, more efficient power distribution and new industries valued in the billions.
