3.2.8 Frequency Roaming
For a flexible management of frequency resource, higher noise immunity and
throughput optimization equipment supports frequency roaming capability based
on MINT protocol.
Any node of the network can be set up as a roaming leader. Roaming leader will
define required radio frequency parameters of the wireless network. Roaming
leader also works with a fixed radio interface parameters, however its radio
parameters configuration is transmitted over the network in special packets so
other node of the network knows whether it is connected to the roaming leader.
Roaming leader also supports DFS and Radar Detection features (if a special
license is installed for selected countries).
A network node can use roaming in order to search for the roaming leader. The
search is implemented by switching between different sets of radio parameters
that are defined in profiles. Each profile contains a fixed set of radio interface
parameters which are set at each search iteration.
Profile parameters:
 freq X[,Y,N-M,...] | auto - radio interface frequency or list of frequencies. Auto
keyword can be used - in this case all frequencies that the unit supports will
be used.
 sid X[,Y,..] - SID of the radio interface (or list of SIDs)
 bitr X - bitrate of the radio interface. Acts as a top limit for the bitrate if
autobitrate mechanism is turned on
 band {double|full|half|quarter} - defines the channel width for the profile. If
profiles use different channel widths, auto mode for frequency cannot be used
 type {master|slave} - node type
 key XXX - secret key
 nodeid N - node ID
NOTE
Profiles of the Roaming Leader are inactive.
