3G and LTE latency speeds do not get a lot of attention, even though numerous operators have cited improved latency as a major reason behind the push to LTE. Latency is defined as the time it takes for a source to send a packet of data to a receiver and is typically measured in milliseconds. The lower the latency (the fewer the milliseconds), the better the network performance.
FierceWireless, with partner OpenSignal, is hoping to shed some light onto the latency issue by reporting network latency speeds of the Tier 1 U.S. wireless carriers every month. Check out this month's results here.
