The heart of Qualcomm’s FLO TV system is the network operations center, which is staffed 24 hours a day, seven days a week. A team of engineers sits at workstations around the dimly-lit room, but the key information is shown on this huge video wall of 24 rear-projection screens that show everything from the shape of the waveform being transmitted by the satellite to the status of all the FLO TV equipment. The screens also show the location and status of the UHF transmitters across the country, the images on every channel, and the bandwidth that each channel is using. The data center that transcodes and stores the TV channels being broadcast over MediaFLO is in the next room, and the transmission equipment is outside the building with the satellite dishes.
