Mesh Intercom
Mesh intercom is a multi-hop technology mesh network intercom (Communication
frequency 470-488MHz). On account of large number of participants and
unrestricted location, people are able to move at will within the effective
range. It is not only superior to the traditional Bluetooth chain intercom,
but has a longer transmission distance and better anti-interference ability.
Features: Intercom with up to 20 people, 5 channels in total. Voice can
be relayed and teams have a maximum communication distance of about 2
kilometers. If participating in campaign mode as a listener, there is no limit
