Q4 MESH Group Intercom System is a multi-rider
mesh network communication model developed for all the
motorcycle enthusiasts.
Allows for maximum 4 riders freely group talking and
ensures connected for varies of directions movement under
the effective distance. The mesh network technology
enables each unit to pair with the nearest Q4 automatically
while the riders changing their queue outside. If one is out
of the distance, it will make a own group itself. When it
reaches to the effective distance, it will back to the previous
group again.
The development of EJEAS MESH Group Intercom
System solved the problem of intercom disconnection that
most motorcycle riders often encounter during outdoor
riding, promoted a better communication though out the
group. The Q4 is a necessary communication tool for all the
motor riders.
