Cellular Mobile Communications - Essay Example However, the question â€Å"how cell phone works† emerges in the minds of people (Brain, Tyson and Layton). The main intention of this research is to discuss and provide a detailed analysis of the new cellular telephony technology, mobile communication principles, cellular system architectures, and cellular system components that participate in establishing cellular mobile communications. Brain, Tyson, & Layton (2009) stated that it is a really interesting fact that cellular mobile communication technology is an advanced form of radio. In other words, it can be said that new mobile phones are very complicated radio; however it is not a radio.
