and disadvantages of both a cellular network and landline network in an enterprise environment. Both offer great advantages and both have their disadvantages. However‚ most organizations use both due to the fast paced‚ technologically advanced society we live in today. As stated above‚ most companies use both landlines and cellular networks. The reason for this is because of the flexibility this configuration offers. They get the reliability of the landline network and the mobility and functionality

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

Propagation: Large-Scale Path Loss 1. (a) Explain the advantages and disadvantages of the 2-ray ground reflection model in the analysis of path loss. (b) What insight does the 2-ray model provide about large-scale path loss that was disregarded when cellular systems used very large cells? 2 .In a 2-ray ground reflected model‚ assume that must be kept below 6.261 radians for phase cancellation reasons. Assuming a receiver height of 2 m‚ and given a requirement that be less than 50 ‚ what are the minimum

of having a purely fixed line network vs. a purely cellular network. When making this decision there are several things to consider‚ the most important is what this network is going to be used for. I am going to first go over the fixed line network then follow up with the cellular network. At the end of this paper I will do a recommendation to a new company that wants to open up a Skype- style service as to whether they should use a fixed line or a cellular network. Fixed line telephones

Wireless network refers to any type of computer network that uses wireless (usually‚ but not always radio waves) for network connections. It is a method by which homes‚ telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building‚ or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place
