AT&T 3G Network Outperforms Verizon Wireless Network - AT&T and Verizon Wireless' legal battle may be over, but the war over their respective network coverage rages with the two companies attacking each other's 3G coverage, speed and capabilities. But an independent examination of the real performance of the two providers' 3G networks shows that while Verizon's map may cover more areas, its claims of a superior mobile data network may be overblown. Root Wireless, a start-up network performance monitoring company, mapped out the network conditions of AT&T and VZW's network in 7 major markets where both operators offer 3G services and found that AT&T's high-speed packet access network (HSPA) consistently beat VZW's EV-DO network in a bevy of different metrics, ranging from download speeds to optimal signal strength. While AT&T still has weak spots in its urban footprint, they are no more pronounced than in Verizon's network, and when extrapolated across the entire market footprint AT&T's fairs far better, producing far fewer peaks and valleys in network capacity and much greater data speeds.
