AT&T today announced that it is boosting the footprint of its Long Term Evolution 4G network on November 20. The handful of new markets include Charlotte, N.C.; Indianapolis, Ind.; Kansas City, Mo.; Las Vegas, Nev.; Oklahoma City, Okla.; and San Juan, Puerto Rico. These six markets bring the total number of markets covered by LTE to 15, increasing AT&T’s LTE coverage to 70 million Americans — which was its goal for 2011. For a limited time, customers who purchase the new LTE-enabled Samsung Galaxy Tab 8.9 will also receive a Samsung Galaxy S II Skyrocket or Samsung Galaxy S II smartphone at no cost. A two year agreement is required on the smartphone.
