wireless Ethernet

An invisible technology, it is similar to a LAN in that the computer to which the network is connected responds the same way it would to an ordinary wired Ethernet. The only difference is that the data packets are transmitted and received over radio waves, not cables or wires. Network devices "built to spec" transmit signals around the 2.4 GHz band. The only problem is that Wi-Fi, HomeRF, and Bluetooth (which all share the same 2.4 GHz frequency range) are not compatible with each other. That could mean disruption, interference, or obsolescence if a different standard should emerge.
