Abstract:-
Now, days so many technologies are developing in every field but most in mobile technology field. Here we will introduce different cellular technologies like GSM, CDMA, 3G, WIMAX, WIFI, UMTS, GPRS, EDGE etc. also provide comparisons & differences amongst them.
We can differentiate & compare each technology on the basis of frequency, bandwidth, voice code, data bit rate, short message services (SMS), sim card, capacity, economics etc.
I. Introduction
Now, days so many technologies are developing in every field but most in mobile technology field. Here we will introduce different cellular technologies like GSM, CDMA, GPRS, 3G, WIMAX, WIFI, UMTS, and EDGE etc. also provide comparisons & differences amongst them. Each technique can be differentiating by their frequency, bandwidth, voice code, data bit rate, short message services (SMS), sim card, capacity, economics etc.
In a cellular network, cells are generally organized in groups of seven to form a cluster. There is a “base station” at the centre of each cell, which houses the transmitter/receiver antennae and switching equipment. The size of a cell depends on the density of subscribers in an area: for instance, in a densely populated area, the capacity of the network can be improved by reducing the size of a cell or by adding more overlapping cells. This increases the number of channels available without increasing the actual number of frequencies being used.
There is Different Technologies introducing as time passes like GSM, CDMA, GPRS, 3G, WIMAX, WIFI, UMTS, and EDGE etc. We will see all those technologies in details they are as following.
