This paper assesses both CDMA and GSM network qualities in South West, Nigeria. Some marketing mix strategies of CDMA and GSM operators were put together in a questionnaire and were administered to respondents of different status, locations and different states. Consequently, hypotheses relevant to the study were formulated for test. These hypotheses were later analyzed and tested using Chi-Square. The results showed tariff as the determinant factor for subscribers to choose their preferred network. Keywords CDMA, GSM, Chi-Square, Hypotheses, Communication 1. Introduction Nigeria is often identified as the fastest-moving economy, and one of the most advanced ICT market sectors in Africa. Little wonder it easily became the telecom hot spot[1]. The deregulation of the communication sector led to the issuance of the first Global System for Mobile (GSM) licence, by the Nigerian Communication Commission (NCC), on 9 February, 2001, after a much-lauded bid sessions earlier, to MTN Nigeria. MTN consequently made its first GSM call on May 16, 2001[2], and later launched full commercial presence in Lagos, Portharcourt and Abuja. Following MTN’s monolithic success, and Nigeria being regarded as one of the fastest growing GSM markets in the world[3], other network providers soon put a foot in the door. They included Econet (Zain), Glo, and Etisalat, in that order. Further, some Code Division Multiple Access (CDMA) network providers evolved too, comprising Starcomms, Visafone and Zoom. This development had been explosive, as the NCC comparatively reckons that as at 2001, the number of working lines was approximately 450,000. This jumped to 7 million and over 70 million respectively by August 2004, and December 2009[3]. Nine years on, and with intense competition, the network providers’ focus seems to be shifting from coverage to improved quality. This study seeks to evaluate the * Corresponding author: olojasegun@yahoo.com (Oloja S. V) Published online at http://journal.sapub.org/computer Copyright © 2014 Scientific & Academic Publishing. All Rights Reserved performance of GSM and CDMA network generally in the South-West, Nigeria. Specifically, it intends, among others, to: Determine the most patronized GSM network, Ascertain and rank the attributes for GSM network patronage, Determine whether network performance is associated with choice of network by subscriber, Evaluate the significance of network attributes in network preference. Mobile number portability is the new services introduced by Nigeria Communication Commission (NCC) in other to get subscribers opportunities to port to network of their choice. As the network providers are wooing subscribers to their network each claiming that they have better performance than the other. How can we ascertain their claims? This work is set to provide answer for this question raised above. That is, this work will investigate how the performance of each network is seeing by the subscriber. This research work is set to get appropriate performance of different network providers. 2. History of CDMA and GSM Technology CDMA technology dates right back to the pre-WWII America. Invented by HedyLamarr and George Antheil in the 1940s, it was used to control the movement of torpedoes by means of using multiple radio frequencies. The military used this as their standard means of communication, as it allows them make completely secure broadcasts, known during that time as frequency-hopping, this technology kept changing and evolving till it reached its present-day status. CDMA was patented by Qualcomm and then adopted by all
