For technical reasons, fixed wireless and DSL are un-competitive with cable for most people. Wireless suffers severely from limited capacity due do a shared transmission medium. Cable has this problem as well but less so because coax supports much greater bandwidth and it is easier to split a cable node than to build more wireless stations. DSL suffers from limited bandwidth and spotty coverage due to loop length limits. In practice few people are able to get DSL service at speeds exceeding 20 Mbps. That leaves cable as sole practical option even for many people in urban areas.
