Of the roughly 2,000 patents Mosaid now has in their vault, CEO John Lindgren claims that a full 1,215 of them are viewed as essential to the use and operation of wireless systems — much more than the 500 found among Nortel's patents.
Thus, radiating cables are used to distribute radio waves in sites where common antennas fail, besides being used as part of wireless systems such as radio detection systems and wireless indoor-positioning systems [5,6].
At the beginning of this paper, it was pointed out that radiating cables can be used as part of wireless systems such as in distribution systems, by providing coverage for in-building cellular scenarios, as well as in radio detection and wireless indoor-positioning systems.
Adaptive modulation is used in the new generation of wireless systems to increase the system throughput and significantly improve spectral efficiency by matching parameters of the physical layer to the time-varying fading channels.
Traditionally, computer simulation techniques are used to perform probabilistic analysis of wireless systems but they provide inaccurate results and usually require enormous amount of CPU time in order to attain reasonable estimates.
The increasing use of indoor wireless systems in office buildings, exhibition halls, factories,... gives rise to a need for indoor propagation prediction models that can be used for different building types, with a sufficient accuracy.
The increasing use of wireless communications systems dedicated to vehicles will require spectrum availability for V2V communication system.
The use of wireless sensor systems for monitoring concrete structures in civil engineering is reviewed.
However, the widespread use of wireless communication systems and continuous advances in archiving technology should overcome the current problems [4].
The growing public concerns about possible effects of microwave (MW) exposure from mobile telephones have been discussed in many countries because of increasing use of wireless communication systems.
