Californian technology firm Qualcomm has announced that it is to wind down its mobile TV service, Flo TV, and sell the spectrum in which the service operated to US carrier AT&T fro $1.925bn. It has been expected for some time that Flo TV would be shut down because of weak sales. However, Qualcomm had suggested that it might reposition its mobile TV broadcast network as a supplemental offering for US operators for the transmission of mobile data. The sale of the spectrum to AT&T indicates that this alternative was not viable for Qualcomm.
