Abstract
  • Experimental results from various studies have proved that the 2.4 GHz ISM band has become increasingly congested. Widespread use of Wi-Fi (802.11) along with incumbent technologies already utilizing this band have made it difficult to provide other wireless services within the same band without an increase in bit error rate and a drop in throughput. The 802.15.4 protocol which has been defined for low data rate networks is currently also being deployed in the 2.4 GHz band. This paper suggests the use of Ultra Wide Band (UWB) as a feasible alternative to deploying a Zigbee based Home Area Network (HAN) on the 2.4 GHz spectrum using Direct Spread Spectrum (DSSS). The FCC has approved the 802.15.4a standard for an UWB PHY layer in a sensor based networks. This study gives an analysis of the standard. The performance evaluation for this standard leads our focus to multi-user interference effects on preamble detection which affects synchronization and timing acquisition in a non-coherent energy detector receiver. The paper also considers two approaches that can be taken up to overcome multi-user interference so that, the inherent robustness of UWB is not overcome by inaccuracy in data reception introduced by interference.
