Hi All
I'm interested in a long-range, low bandwidth, low power mesh network.
I'm wondering if it's as easy as buying a Tplink 3020, sticking OpenWrt on it and plugging in a LoRa USB
The exceptional high range of LoRa (and other IoT radios) comes at the price of several constraints. Mainly limited throughput, packet size and duty cycle.
I dare to say that none of the popular 802.11 based mesh protocols are suitable in combination with IoT-focused wireless technologies.
Within IoT-based wireless technologies it's not uncommon to talk about messages at the size of just a few bytes instead of kilobytes and how few messages per day can be transmitted to a node.
In this respect I'm pretty sure a routing protocol needs to be an integral part of the IoT infrastructure itself to not eat up all the available ressources and those leave room for some real application payload.
While also the application software itself needs to be adapted to such an environment to not create too many (or too big) messages and those render the network useless for concurrent access.
Kind regards, Franz
