   Abstract : As the wireless technology maturing, the wireless systems are evolving towards the development of new applications with broad band access and also the higher data rate. This necessity will give rise to the new WLAN standards as well as minimizing the cost, high QoS and security features of the wireless setup. READ MORE

4. 3. UWB Measurement Techniques and RF Coexistence in a Mobile Handset

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Erik Holmgren; [2006]
   Keywords : ;

   Abstract : There are two typical interference problems in a multi-radio platform, i.e. blocking due to the saturation of the front end of a receiver by the high power radiation from another transmitter, and desensitization of the receiver by the in-band noise generated by the other transmitter. The UWB device is not an exception. READ MORE
