We are trying to construct a wireless mesh network. We currently have single band routers that operate on 2.4GHz. We have also succeeded in meshing the two routers.
We have chosen B.A.T.M.A.N Advanced layer 2 mesh protocol. Therefore for mesh devices we do not need IP address to communicate. Currently the router is flashed with OpenWRT and operates on two modes simultaneously.
- Adhoc mode (for mesh) forms the backbone network.
- AP mode (for allowing non-mesh devices to connect via layer 3) for client network.
We know this setup with only single band router with single radio will be unusable over the long run since the same radio have to operate on both adhoc and AP mode at the same time causing interrupts.
We were looking out for dual radio routers and found a lot of dual band routers, so that 2.4GHz can be used for client networking in AP mode and 5GHz band can be used for mesh backbone in Adhoc mode. Therefore two different channels.
What we are confused at the moment is, does the simultaneous dual band routers mean they have dual radio (or) they manage using single radio?
