In this paper I will go over the pros and cons of having a purely fixed line network vs. a purely cellular network. There are several things to consider when making a decision regarding fixed lines vs. cellular network, I think the, most important one is finding out, when, and where is the network going to be used. 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. In today’s society, every home and building owner have the ability to choose to have a fixed line network or cellular (wireless) network, to receive or transmit data over the fixed line a modem is needed on each end of the line. The modem/ router take the digital information and turn it into segments that have been specifically selected for the transmission over the telephone network. The modem on the other end is responsible for turning the segments back into the digital data. Up until the DSL was created, the modem’s job was to transmit data over a telephone network that is designed for voice so the data rates were limited. Since DSL utilized the same telephone line, there was 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.
Most modems these days are capable of acting as a gateway in a very limited capacity. But typically, a modems job is to do just that
