Verizon CTO Tony Melone in a speech at the TIA conference said Verizon would be using Wi-Fi to help offset heavy cellular demand. He was adamant that it wouldn't "cover up flaws and capacity limitations," a slam against AT&T's public hotspots often going up in areas where its 3G network is poor, but admitted it would be used to bolster performance. Rollouts would primarily center around homes using routers as well as at stadiums, where even the best networks can struggle coping with tens of thousands of simultaneous users in a small area.
