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.
