Nigeria. Received 23 August, 2013; Accepted 24 June, 2014 Mobile network communication system offers the users with seamless communication and this has caused wireless communication to increasingly become the preferred method of carrying multimedia traffic or messages such as voice, video, images, and data files. Time division multiple access (TDMA) is the multiple access scheme used in global system for mobile communication (GSM), while third generation (3G) system uses wideband-code division multiple access (W-CDMA). The former is designed majorly for voice and a little of data. Due to the increase in number of phone users and the services enjoyed by the users, there is higher demand for non-voice services, mobile extensions to fixed-line services and richer mobile content. This has caused the network operators to develop 3G system with the goal of providing a network infrastructure that can support a much broader range of services than existing systems in which its penetration level has reached market saturation. This paper presents a comparison of the two wireless systems performance based on their modulation techniques. From the constellation gotten, the two systems were analyzed and the analysis shows that W-CDMA (that is, 3G) provides a network infrastructure that can support a much broader range of services than existing systems (GSM) because the main forces behind development of the 3G have been driven by the second

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
