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
