In this paper I will go over the pros and cons 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 was the main form of communication in 1877 and this was the case up to the time when cellular phone came into the world. Fixed lines are in every home and building today so everyone has the ability to have telephone and data service. To receive or transmit data over the fixed line a modem is needed on each end of the line. The modem takes the digital information and turns it into tones that have been specifically selected for the transmission over the telephone network. The modem on the other end is responsible for turning the tones back into the digital data. Modems transmit data over a telephone network that is designed for voice so the data rates were limited until digital subscriber line (DSL) was introduced. DSL utilizes the existing analog phone line so no need for new equipment other than modems that can convert the digital data into high-frequency tones along with a filter at the subscribers end to keep the DSL transmission from being heard on the telephone. The conventional modem operated at the frequency range of 300 to 3,000 Hz but a DSL modem will need to operate a higher frequency range which will allow for a much higher

data rate. The data rate was capped at 56,000 bps with the conventional modem but with the DSL modem the data rate is based on several physical characteristics. One of the major physical characteristics is the cable length, the farther away from the central office the lower the data rate. The data rate for DSL can range from 256 kbps to 20 Mbps, which is a very big difference from the analog connection everyone used before DSL came along. Network security is very important on any network with a DSL connection on a fixed line there is no change in the network security. Network security would be handled by a firewall that would be handled by the modem and of course at the device itself. Then the subscriber or company would themselves use additional software for further protection. Troubleshooting is handled by both the subscriber and Telephone Company. There is a way to determine where one ends and the other begins this is known as the demarcation line. This is usually where the wiring enters the home or building. But this really depends on if this is a single occupant property or a multiple occupant property. The failover solution when using a fixed line service for Internet connection would be to have back up equipment available for the site and for the Telephone Company it would be good to know at the central office there is additional servers just in case there is a malfunction. When it comes to the data itself it is always important to have a backup ran on a daily or weekly basis depending on the importance of the data. When Cellular phones first came out the main use was to make phone calls. The first generation of the cell phone transmitted information the same analog format as a fixed line. The second generation (2G) transmission switched to digital which gave cell phones the ability to

transmit and receive voice and data. When 2G took off and the demand for Internet access was required the introduction of third generation (3G) technology which has a higher data rates and allowed for multimedia applications. 3G is still in use but there is now a fourth generation (4G) technology that will have 10 or more times the data rate as the 3G network. A cellular network system is broken into small geographical areas called cells;...
