RTX has launched what the company claims is the world’s smallest fully embedded Wi-Fi module, the RTX4100. The module features a small footprint (30x18mm), high efficiency, and low power consumption, incorporating Energy Micro's EFM32 Gecko MCU and the Qualcomm Atheros AR4100 Wi-Fi System-in-Package. The RTX4100 also features both a built-in and an external antenna, and can be integrated into devices supporting various wireless standards including 802.11 b/g/n. 

The RTX4100 Wi-Fi module is designed for fast and easy application development of low power sensor and actuator solutions, enabling devices, machines and other systems to connect directly to the Internet for a wide range of emerging machine to machine (M2M) applications. Embedding Wi-Fi directly inside a device makes installation simple as it can use existing infrastructure and works “out of the box” with applicable cloud services. Customers can choose from a range of different libraries to rapidly enable emerging white goods and smart energy applications to be integrated using a zero-cost tool chain..

The module is an expansion of the Qualcomm Atheros ecosystem that leverages the AR4100 low power 802.11n Wi-Fi, enabling use of small foot print, low cost, and low power microcontrollers for the ‘Internet of Things’ application space.


The RTX4100 Wi-Fi module will be demonstrated on Energy Micro's stand 1-523 during Embedded World from 28th Feb. to 1st Mar. 2012.
