US cellco MetroPCS has announced that it has launched its 4G wireless network in Detroit, Michigan, the third city in its planned nationwide rollout. As previously reported in CommsUpdate, MetroPCS switched on its inaugural Long Term Evolution (LTE) wireless network in Las Vegas in September, cementing its place as the first mobile operator to launch commercial LTE services in the United States. Shortly afterwards the company initiated a second 4G network, in Dallas, Texas. Further network rollouts – in Boston, Atlanta, Jacksonville, Los Angeles, New York, Miami, Orlando, Philadelphia, Sacramento, San Francisco and Tampa – are scheduled for deployment late this year, and early 2011. Roger D. Linquist, president, CEO and chairman of MetroPCS commented: ‘Expanding our 4G LTE network to Detroit marks a key milestone for the company – [we are] bringing 4G mobile broadband services to customers and consumers who want to experience more, and who demand more value. We look forward to expanding 4G LTE coverage throughout Eastern and Western Michigan throughout 2011’.
