Frequencies

Wi-Fi Frequencies and Channels

When configured as a mini-Access Point, the CANlink® wireless 4000 can operate one of many channels.

The Server selects the channel (which defines the frequency), and the Client selects the band, and connects on that frequency if the SSID is found.
(This is not 100% true, if User-defined channels are utilized).

Note

Not all channels are available in all regions worldwide.
See Regions for details.
