Mutual interference effects in closely-located HDR and LDR WPANs

Wireless Personal Area Networks (WPANs) are short-range ad-hoc networks centered around a person that make use of unlicensed bands for data transmission. Several transmission schemes such as Ultra Wide Band (UWB) or Spread Spectrum (SS) have been proposed for both Low Data Rate (LDR) and High Data Rate (HDR) WPANs. Such transmission schemes are designed to comply with the different requirements of LDR and HDR WPANs. These requirements are complementary in terms of data rate, but not in terms of coverage. It is thus an interesting topic to integrate LDR and HDR air interfaces in a dual-mode wireless device.
