Teledatics, in collaboration with Newracom, is developing the TD-Halom, a 1W (30dBm) Wi-Fi HaLow module featuring the NRC7394 IC. The module, measuring 18 x 13.5mm and 2.4mm high, will operate over 902 – 928 MHz, the maximum power allowed by the FCC. It supports AP, station-client, and 802.11s mesh operations up to 15Mbit/s.
“This has been the fruition of a lot of hard work and support from both Teledatics and Newracom engineers, and the TD-Halom will showcase the true distance and signal penetration capabilities of Wi-Fi HaLow as a technology allowable by federal regulations,” said Teledatics CEO James Ewing.
The module features an Arm Cortex-M3 for stand-alone use, an on-board RF transceiver, and a u.FL IPEX connector for an external antenna. It will be available with an evaluation kit for Raspberry Pi or an M.2 interface board. Applications include drone operation, industrial sites, and wide-area outdoor connectivity.
An M.2-compatible board carrying the module will also be available, featuring USB, UART, SPI, and I2C interfaces, and can act as a Linux USB Wi-Fi dongle or operate in stand-alone mode.
Wi-Fi HaLow?
Wi-Fi HaLow is a brand for communication conforming to IEEE 802.11ah, which uses sub-GHz bands to augment Wi-Fi for long-range operation – up to around 1km. It aims to serve as a physical layer for wireless IoT nodes in sensor networks or wearables, potentially allowing them to operate for months or years on a coin cell.
