1.0 Introduction to Cellular Communications Mobile Communications Principles Each mobile uses a separate‚ temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once‚ using one channel per mobile. Channels use a pair of frequencies for communication one frequency (the forward link) for transmitting from the cell site and one frequency (the reverse link) for the cell site to receive calls from the users. Radio energy dissipates over distance‚ so mobiles must stay

methods are the Tulsa Model and the Marzano model. The method of evaluation that will be utilized for this report will be the Tulsa Model.
