802.11n Smart Meter Communications Module

The RS-SE-201 module is a complete IEEE 802.11bgn 1x1 Wi-Fi module for in-home smart-energy device communications. It provides low-power wireless transport to any device with a serial interface for data transfer. The RS-SE-201 hardware integrates a MAC, Baseband, RF transceiver, power amplifier, a frequency reference, and an antenna. The embedded firmware implements all WLAN protocol and configuration functionality, networking stack, and HTTP server to make a fully self-contained 802.11n WLAN solution for a variety of applications. No networking functionality or WLAN configuration is required on the host system or data source. RS-SE-201 provides advanced Wi-Fi security, ultra-low power operation and standards compliant wireless connectivity to in-home smart-energy devices and appliances. As a wireless modem, it originates and terminates TCP and UDP connections, enabling a variety of applications at low cost and small footprint. It uniquely provides connectivity in the single stream 802.11n mode, preserving overall network throughput.
