BYOMesh – New LoRa mesh radio offers 100x the bandwidth
A new development in 2.4GHz LoRa radio technology promises a 100x increase in bandwidth for long-range mesh networks. This innovation allows for high-bandwidth, long-distance communication without the power, complexity, or licensing overhead of alternatives like WiFi or Halow. It opens up significant new possibilities for robust, high-capacity backhaul links, especially in challenging environments.
The Lowdown
The "BYOMesh" post introduces a significant advancement in LoRa radio technology, specifically leveraging 2.4GHz to deliver a substantial increase in bandwidth for long-distance communication links. This development aims to bridge the gap between traditional low-bandwidth LoRa and more power-intensive or complex alternatives, offering a compelling solution for robust mesh networks. The discussion highlights the technical implications and potential applications of this enhanced LoRa.
- The core innovation lies in using 2.4GHz LoRa, which enables up to 100 times more total bandwidth compared to existing LoRa setups.
- This higher bandwidth is achieved without the typical drawbacks of other high-throughput wireless technologies, such as increased power consumption, system complexity, or stringent licensing requirements (common with WiFi, Arden, or Wifi HaLow).
- The author highlights the potential for "long meshcore backhaul links," citing examples like those found between high mountains in the Pacific Northwest, as beneficiaries of this improved capacity.
- The underlying technology appears to be related to the Semtech SX128X transceiver, as indicated by a linked datasheet.
This advancement represents a meaningful step forward for long-range, low-power wireless communication, potentially enabling more capable and widespread mesh networks by drastically increasing data throughput while maintaining LoRa's core advantages.
