In recent tests conducted by Computerworld, Sprint's 4G Xohm network showed latency performance far superior to the AT&T "Broadband Connect" 3G network, with higher throughput as well. Where downloads ran at about 1.3 Mbps to 1.7 Mbps for Broadband Connect and 3.4 Mbps to 4.4 Mbps for Xohm, the more-important statistic might have been the latency figures.
Where the AT&T 3G network had a "ping" response of about 234 milliseconds, the 4G Xohm network had 97 millisecond pings. In layman's terms, Xohm-delivered applications responded faster to user requests.
Low-latency performance--sometimes described as latency performance identical to a traditional wired network--has been a key design goal for the Xohm network, and has been deemed important for support of real-time applications.
