When DSSS and FHSS fail: Avoiding interference on the 2.4GHz wireless desktop

Posted: 06 Nov 2007     Print Version  Bookmark and Share

Keywords:2.4GHz  wireless desktop protocol  DSSS  FHSS 

The three popular IEEE-based wireless technologies, Wi-Fi, ZigBee and Bluetooth, employ Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) schemes respectively to maintain the link integrity and cope with interference problems of the 2.4GHz band. These schemes work well but when it comes to ultra-low power wireless connectivity, these schemes demand power resources that just are not available. This article proposes the use of an asynchronous, high performance wireless desktop protocol (WDP) as a way around the 2.4GHz band traffic.
