Company Profile

Udacomm is a start-up that is working towards commercializing through-air wireless ultrasound. For short-distance and low data rate applications, replacing the conventionally-used Radio Frequencies (RF) by ultrasonic frequencies enables an order-of-magnitude reduction in the communication power consumption. This prolongs the battery life significantly and thus reduces the need for frequent battery replacements. RF based wireless communications for small-form-factor devices use carrier frequencies of hundreds of MHz to several GHz. The associated electronic receivers and transmitters must be designed to handle these high speeds which come at the price of substantial power dissipation. Regular battery replacements are required, which are both difficult and costly. Ultrasonic carriers can have low carrier frequencies (from a few tens of kilohertz to a few MHz), which enables an order of magnitude reduction in the power consumption of the sensor electronics. A proof-of-concept has been demonstrated by building and field-testing a custom-designed ultrasonic receiver Integrated Circuit (IC).
