WLAN Channels and World Mode (Client Mode only)
Which channels are available for WLAN communication is restricted by the regulatory domain
where the unit is operating. Anybus Wireless Bolt supports regulatory domain detection
according to the IEEE 802.11d specification.
The unit is initially set in
World Mode
which enables only the universally allowed channels in the
2.4 GHz and 5 GHz bands (see the table below). World Mode can be disabled and additional
channels added using AT commands. The unit will then search for country information during the
scan. If the scan indicates that the unit is operating within either the European (ETSI) or North
American (FCC) regulatory domains, the additional channels will be enabled. A new scan will be
performed every hour to update the regulatory domain.
If no country information or conflicting information is detected, the unit will revert to World
Mode. The unit must then be restarted to update the regulatory domain.
See the
AT Commands Reference Guide
or the
Help
page in the web interface for more
information about how to use AT commands.

Notes
•
The maximum output power will be reduced on some channels depending on regulatory
requirements.
•
WLAN communication may take a longer time to establish during startup if World Mode is
disabled and additional channels are used.
