Nov 12, 2013In consumer and industrial applications, end users appreciate the convenience of cable-free connectivity, and the license-free 2.4 GHz ISM band is often a suitable choice. Protocols of technologies such as Bluetooth or ZigBee are robust enough to overcome the interference that 2.4 GHz transceivers encounter, but these protocols are feature-rich, which means they are applicable to a wide range of applications, but are over-specified for simpler applications. What's more, the microcontroller (MCU), normally intended for other functions, must deal with the heavy overhead of running a large protocol software stack. To address these shortcomings, AMS' Prashant Dekate discusses a transceiver architecture that removes almost all processing overhead from the MCU and allows for an easy and quick implementation of the radio network.
