### AI overview

This article introduces OpenMANET, an open-source long-range wireless mesh networking project using Raspberry Pi hardware and Wi-Fi HaLow chips. It compares OpenMANET with LoRa-based Meshtastic, noting higher bandwidth and features such as push-to-talk, GPS sharing, video streaming, and ATAK integration, alongside higher hardware cost and power consumption.

### Source excerpt

OpenMANET is an open-source project for building long-range wireless mesh Mobile Ad-hoc Networks (MANETs) using Raspberry Pi SBCs and Wi-Fi HaLow (802.11ah) chips from Morse Micro. This came up when we wrote about Morse Micro USB WiFi HaLow adapters, and an X user commented that "OpenMANET is going to explode with these available, no more adapter boards or M.2 cards". OpenMANET targets search and rescue, disaster response, airsoft events, and other off-grid or infrastructure-failed situations. So it looks like an alternative to LoRa-based Meshtastic and Meshcore, with higher bandwidth, at the cost of more expensive hardware and higher power consumption. OpenMANET supports field communications, including push-to-talk, sharing GPS positions, cameras/video streams, and ATAK (Android Team Awareness Kit) integration. The mesh network can access the Internet through a single "mesh gate" over Starlink or cellular connectivity. The project supports a range of hardware platforms including Gateworks Venice, Raspberry Pi Zero 2 W, [...] The post OpenMANET - A higher-bandwidth Meshtastic alternative leveraging 802.11ah WiFi HaLow appeared first on CNX Software - Embedded Systems News.
