The resulting application overcomes the major shortcomings of IR-based remote control. Included in the application note are descriptions of the system architecture and associated functional modules and PSoC projects.
Introduction
This application note focuses on an RF-based remote control device operating over the 2.4-GHz ISM (industrial, scientific, and medical) band. Because it uses Cypress’s proprietary WirelessUSB-NL radio, the device overcomes the following shortcomings of IR-based remote control:
- line-of-sight pointing
- limited operating angles
- short transmission range
- reflection problems
- high current consumption
