‘Verizon Wireless will plug in a mobile cellular site that it calls "cell on wheels" for the Buffalo Bills game, the company said. More than 70,000 fans can fill the stadium’s bowl during games, the equivalent of a small, garrulous city that can overload Verizon’s four transmitters in the area, marketing director John O’Malley said. "We did have instances where some sites experienced blocking of calls," he said. Cellular companies can divide their frequencies among an almost unlimited numbers of users, but the feat takes multiple transmitters to accomplish. The temporary site, hidden in 12-foot enclosure near a stadium gate, can connect 100 calls at once, effectively doubling Verizon’s capacity in and around the stadium, O’Malley said. It will be in place throughout the football season, using an antenna mounted on the stadium’s administration building. The temporary tower is part of Verizon’s deal with the Buffalo Bills as its official provider of wireless service, O’Malley said.’
