Network Latency

A second measure of network performance is network latency, which is the amount of time it takes for a network packet to make a round trip between endpoints. Wireless carriers rarely quote latency figures for their networks, but latency can have a dramatic effect on the perceived performance of your application. Like bandwidth, there are many factors that impact the latency experienced by your application. The primary factor is the inherent latency of the wireless network technology used to connect the device to the rest of the world. Figure 7-3 shows the best-case latency figures for common network standards.
