Frequency Shifters for Wi-Fi

Doodle Labs’ family of Wi-Fi Frequency Shifters (WiFi-FES) provide flexibility to system integrators looking to deploy their existing wireless modems at special frequency bands to expand the market opportunities. The WiFi-FES is an in-line module placed between the radio modem and the antenna. Our Prism® frequency shifting technology helps achieve the use of state-of-the-art MIMO performance in any frequency band. Additionally, the WiFi-FES amplifies the Tx power and Rx gain to increase the wireless range. A large family of form factor compatibile modules in the 100 MHz – 4 GHz range means a simple swap of the WiFi-FES module to switch to a different band to meet customer’s requirements in any market or country. One of the primary use of the WiFi-FES blocks is to integrate with newer generation SBC boards with built-in Wi-Fi connectivity to develop Industrial Internet applications that require long range and avoid interference.
