How fast is that wireless technology?

Use the pulldown menus below to match the approximate transmission rate with the the wireless technology that achieves that rate. Of course, sender/receiver distance, noise and other factors determine actual transmission speed, so "your mileage may vary" (YMMV).

Infrastructure Mode.

What is meant when we say that a network of devices is operating in "infrastructure mode"?

All network equipment, except the mobile devices, must be racked in a temperature-controlled and power-smoothed building.

Devices communicate with each other and to the larger outside world via a base station (also known as an access point).

The mobile device is operating in a reduced power mode, forcing the network base station and routers to take on additional functionality that would normally be done by the mobile.

Network devices can communicate directly with each other, with no need for messages to be relayed through a base station. The devices are the "infrastructure".
