Anatel to hold further discussions on 700MHz auction

10 Apr 2014

The Brazilian telecoms regulator Anatel is to meet today to discuss the planned licensing of the 700MHz band for Long Term Evolution (LTE) 4G mobile services. Among the items on the agenda are the possibility of issuing regional licences rather than national permits plus the opportunities for spectrum sharing between operators. Earlier this week the Media Council of the National Congress decided to postpone the 700MHz auction until August after it was ruled that more time was needed to examine the likelihood of interference between LTE services and digital terrestrial television (DTT) broadcasts in adjacent bands.

As reported by CommsUpdate in February this year, Brazil’s Society of Television Engineering (SET) voiced concerns that interference between LTE and DTT could cause ‘disruption in programming, frozen images or a black screen’. Anatel published Resolution 625/2013 last year, establishing the 698MHz-806MHz band for LTE-based services, while digtal TV transmissions in Brazil use the adjacent 470MHz-698MHz band. The TV organisation’s president, Franco Jose Olympio, commented: ‘… a combination of various mitigation measures are needed to preserve the quality of the reception of TV signal. Among them, change the antennae and add filters in TV and LTE transmitters.’
