The ever increasing mobile data speeds are causing an ever increasing need for more bandwidth by the Mobile Operators. This can only be met by moving up in frequency. We now see 2.6 GHz being deployed for LTE mobiles. What band do we use next? 3.5 GHz and 5 GHz are both possibilities but both these bands have very limited coverage. The answer at some point will be mesh networks.
The focus on mesh in the Kernel is timely. One problem that needs to be solved is the time it takes for route discovery. If we do end up with "mobile mesh" then vehicles will be one of the most important nodes (large power source with decent antennas at a good height). The problem is that most of these nodes move at significant speed (when compared with the size of the mesh cell at 3 GHz and above).
Low latency rebroadcast of messages or some smarter route discovery algorithm need to be priorities if mesh is to work in the next generation of mobile networks or beyond (5G or 6G).
