BT Sport has selected Ericsson to design, build and run the technology behind a variety of new products, as it ups its game in live sports, having won the Champions Leagues broadcasting rights.
Ericsson will work on BT's three new sports channels, BT Sport Europe, BT Sport Showcase, and BT Sport ultra high definition, which will launch on 1 August.
Ericsson has also had its contract extended on existing BT Sports channels from six years to nine years.
