Halo TD-XPAH: Open source 802.11ah scalable remote Wi-Fi development platform (schematic, PCB, etc.)

Halo TD-XPAH is the first open source hardware IEEE 802.11ah Wi-Fi development platform available to creators, manufacturers, engineers and experimenters. The IEEE 802.11ah Wi-Fi protocol builds on Wi-Fi 6, adding the ability to reach at least one kilometer (half a mile) from the access point to the client. 802.11ah is designed to support up to hundreds of clients per access point through restricted access windows, a form of time division multiple access (TDMA). It also supports 802.11s mesh networking, where remote nodes can link to and hop between nodes closer to home to further extend range.

The TD-XPAH board supports two operating modes: USB dongle mode connected to an external system and standalone mode. Since 802.11ah is a Wi-Fi protocol, TD-XPAH supports TCP/IP and works with standard networks. Our open hardware accessory board Kicad "hAT" template can be used to create custom hardware for remote control, monitoring and sensor systems that extend existing wired or wireless networks. We included three hardware hAT designs in the TD-XPAH release, adding Ethernet connectivity, standard 2.4 GHz Wi-Fi communications and an air quality sensor platform.

Here are a few examples of Halo TD-XPAH:

Long-distance wireless camera system
Distributed air quality sensor system
Remote solar field monitoring network Remote
airborne drone link
Wide-area soil moisture and plant health reporting network
RS-485 wireless communication to replace copper wire
Ad hoc emergency communication platform
