Therefore improvements in the quality of service, power efficiency and reduction of parasitical interference and radiation are a must as presented in this paper. It is especially true for the new 3G and 4G cellular generations where the system handset power levels and bandwidth are increased. The mitigation techniques described in this paper for systems base stations and mobile handsets can contribute to the required improvements. However considerable more efforts are still needed in order to improve mobile radio communication to an efficient, secure and convenient system useful for the welfare and positive advancement of our global society.
