TDD time division duplex radio, in the mesh network communication, implements Store Forward Repeater. In this way, every time a packet passes through a relay, it needs to increase the transmission time T of a link. That is to say, the same data packet is transferred once and the total transmission time is increased by one T. So, multiple transits are the actual broadband after multiple hops, from 1 hop, 2 hops, 3 hops, 4 hops... N jumps, D/T, D/(T+T), D/(T+T+T), D/(T+T+T), D/(T+T+T+T)... D/nT equals 1,1/2,1/3,1/4 of the original link bandwidth... 1/n.
A MimoMesh wireless broadband MESH using frequency reuse-wavelength division multiplexing technology, it can ensure that after the third hop, the actual data rate will not decrease. That is, 2 jumps fall to 1/2, 3 jumps fall to 1/3, 4 jumps, 5 jumps... N jump still is 1/3, no longer falling.

From the statistical data in the table, comparing the uplink and downlink data of three to four hops, it can be seen that the bandwidth of MimoMesh ad hoc radio stations does not decrease after three hops.
The 2km test uses a backpack radio station with a 20M bandwidth that can reach 44Mbps and 3km in locations where other stations cannot be directly connected, and our station has achieved direct access.
