We designed HamWAN this way because it offers a number of technical advantages around frequency use, throughput, signal strength, and others.</div><div class=""><br class=""></div><div class="">“Mesh” as most people know it treats every node as a router on the network, and uses a single wireless channel. This somewhat forces the use of Omni antennas so that things can talk to each other. Low gain in the antennas, plus low output power from the common gear folks use (the stereotypical WRT54G), means that it’s very difficult to actually form a “Mesh” over any sort of real world distance. Once you do have a connection, then you start running into issues with contention from the single wireless frequency, and throughput halving for each hop in the network.</div><div class=""><br class=""></div><div class="">I think in your case, it’s going to be important to determine what the use cases are, and the area you want to cover. HamWAN has the cost structure shifted towards the cell sites being expensive to keep the client side cheap. We believe we’ve engineered it to provide a better, more reliable and performant network than Mesh can provide at any sort of real world distance, but your use case or situation may vary.</div><div class=""><br class=""></div><div class="">I’d encourage you to join us on our IRC channel, where there are folks online most anytime, who are happy to answer more specific questions.
