PTS finds no TV interference from 800MHz services

Sweden’s telecoms watchdog, Post & Telestyrelsen (PTS), reports that it has found no evidence of interference to terrestrial TV broadcasting from 800MHz mobile services. Licences in the ‘digital dividend’ 800MHz band were issued in March 2011 to cellular operators Hi3G, Telia, Telenor and Tele2, which are using the spectrum to expand 4G coverage. Because terrestrial TV broadcasts use adjacent frequencies, reception interference is a risk, but the PTS says that although it has received 33 consumer complaints of interference in the last year, its field measurements have not been able to establish that it is 800MHz transmitters causing the problem.
