A special transmit polarization signalling scheme is presented to alleviate the power reduction as a result of polarization mismatch from random antenna orientations. This is particularly useful for hand held mobile terminals typically equipped with only a single linearly polarized antenna, since the average signal power is desensitized against receiver orientations. Numerical simulations also show...
The development of handheld mobile terminals (MT) capable of operating over both cellular networks and Wireless Local Area Networks (WLAN) is an important step towards the evolution of next-generation integrated networks. For real-time applications, maintaining a seamless connectivity and an acceptable level of quality is essential, and efficient vertical handover (VH) algorithms are required. This...
Handheld mobile terminals have developed from simple phones to devices featuring a wide variety of modern multimedia functions, being in fact multimedia computers. In today's mobile terminals, computational demand is closes to that of personal desktop computers only a few years ago. All these new features need more power and bandwidth in interconnections. New innovations must be implemented in these...
This paper considers a realistic evaluation of the power mobile handsets are able to transmit and receive. It has been suggested to use the so-called total radiated power (TRP) and the total isotropic sensitivity (TIS) for the uplink and downlink, respectively, which may be seen as special cases of the general mean-effective-gain (MEG) measure. These measures are computed from the spherical radiation...
