Opto 22's Snap PAC programmable automation controllers are the first to offer wireless networking and standard Ethernet networking. This wireless technology is based on the IEEE-802.11 specification with support for a, b, and g networks operating in the license-free 5 GHz (802.11a) and 2.4 GHz (802.11b/g) frequency bands. Snap PAC wireless supports both infrastructure and ad hoc mode.
