Researchers at the Karlsruhe Institute of Technology (KIT) suggest governments should not auction off old TV frequencies to the highest bidders-- instead they be used to create a free "super wifi" network.
Old TV frequencies allow the transmission of wifi over lower frequencies , resulting in coverage as wide as several kilometres in radius. Such a network could replace pricey mobile services of the 4G variety, leading to far wider mobile internet use.
Current wifi technology operates at high frequencies of 2GHz and above.
The KIT researchers say they also have a technique for the prevention network congestion via the reserving of a 90MHz interval in the UHF bands. Another argument in favour is that in any case the general public should be given preference to the use of electronics communications.
