	Lower-end microcontrollers can by attached via TTL serial to a wireless-capable terminal server. Implementing a wireless chip set requires careful RF board layout and is not recommend for those without microwave experience. Some vendors include a reference board layout with their chips.

	Wireless Ethernet uses unlicensed spectrum in the 2.4 and 5.8Ghz range in the U.S. 14 channels are usually avaialble, and a wireless site survey is recommended before choosing equipment and install locations. Typical implementations include wireless access points that function similarly to wired Ethernet switches and wireless radios on particupating nodes.
