Mobile Latency

wifivslte.pngIlya Grigorik, developer Advocate at Google, has an interesting new post on his blog comparing the latency of WiFi and 4G networks. He concludes that WiFi can deliver low latency for the first hop in the network if the network is idle. 4G requires more coordination between the device and the radio tower but can provide more predictable performance.

He recommends apps don’t trickle data and instead aggregate network requests to both reduce energy use and reduce the overall latency.

I have previously written about chatty APIs, a call for more energy efficient apps and latency.
