 Look provided its digital television and wireless Internet services using a Multichannel Multipoint Distribution System (MMDS) technology, operating with 90 MHz of capacity in the 2.5 GHz band (the only company in Canada with approximately 90 MHz of spectrum and a broadcast license for mobile video services in Canada).Look had exclusive use of these frequencies since it received licenses from the Canadian Radio-television and Telecommunications Commission (CRTC) as a "broadcast distribution undertaking".With this MMDS technology, television, audio and data signals were received at Look's headend and digitally transmitted via fibre optics links to broadcast sites.
