Qualcomm’s FLO TV is tackling one of its big challenges – coverage – head on with the launch of its service in 19 more markets around the country.

The expansion, coming ahead of the DTV transition in June, is a precursor to its nationwide expansion, which will reach more than 200 million consumers in 100 U.S. markets by the end of this year.

FLO TV’s service now covers previously unserved portions of 16 existing markets and provides coverage for the first time in three new markets: Atlantic City, N.J.; Greensboro, N.C. and Wilmington, Del. The expansion is the result of approvals obtained from the FCC ahead of the DTV transition. Some TV stations are going ahead with their conversions even though the FCC pushed back the DTV transition deadline from February to June.

Existing service markets that will receive enhanced FLO coverage include: Austin, Texas; Baltimore/Washington, D.C.; Chicago; Dallas, Texas; Jacksonville, Fla.; Kansas City, Mo.; the greater Los Angeles area; New York City; Oklahoma City, Okla.; Orlando, Fla.; Phoenix, Ariz.; Pittsburgh, Pa.; Portland, Ore.; Reading, Pa.; San Antonio, Texas and St. Louis, Mo.

FLO TV also says it continues to expand service with the availability of tools and support for OEMs to integrate FLO TV on Windows Mobile platforms.

FLO TV is available to AT&T subscribers as AT&T Mobile TV and to Verizon Wireless customers as V CAST Mobile TV in 68 markets nationwide.
