Gateworks GW16146 is an 802.11ah WiFi HaLow Mini PCIe module

Gateworks GW16146 is an 802.11ah WiFi HaLow Mini PCIe card designed to provide long-range wireless to IoT applications utilizing the company’s Venice and Newport single board computers. We first noticed 802.11ah WiFI LPWAN standard operating at 900 MHz for the Internet of Things in 2014, followed by Newracom NRC6101 chip in 2015, and the following year the Wi-Fi  Alliance decided to call the new standard “Wi-Fi HaLow“. I was expecting it to compete with the likes of LoRa and NB-IoT, but I have not heard much about it, and when I asked a WiFi module and board supplier earlier this year, they seemed surprised I would even be interested in this type of hardware and, obviously, did not have any… So it’s good to see some new hardware coming out. Gateworks GW16146 specifications: 802.11ah Halow connectivity Silex SX-NEWAH 802.11ah Module based on Newracom NRC7292 System-on-Chip (US only) Compliant with IEEE […]
