Acknowledgement I am honored to prepare this research paper which titled “Why GSM Tech is more preferred than CDMA Tech in Yemen”. And I would like to pay my special thanks to Dr. Murad

Abstract
The cellular industry is in Yemen dominated by two technologies - Global System for Mobile Communication (GSM) and Code Division Multiple Access (CDMA). This paper will provide an overview of the two different technologies and will focus on why people in Yemen preferred to use the GSM technology rather than CDM technology A even though CDMA technology introduced after GSM with a more privileges.

Chapter 1 Background

Introduction

The mobile industry in Yemen is divided between the two technologies GSM and CDMA. While the earlier service providers had adopted the GSM technology, the new players have been using CDMA technology has notched up a significant share of the Yemen market. The number of subscriber’s mobile industry has increased significantly since 2001. The first company lunched in Yemen introduced the GSM technology which was the only choose for Yemenis people to grant, but in 2005 other company has been lunched by the government introduced the CDMA technology which provide a better services for the clients with privileges to overcome the GSM technology. After around five years a big number of people have subscribed with CDMA, but GSM was still demonstrated the market with a bigger number of subscribers until nowadays.

It is necessary for us to understand the basic differentiation of the two technologies as they may have an impact on the subscribers. GSM stand for Global System for Mobile Communications, one of the leading digital cellular systems. It uses narrow band TDMA, which allows eight simultaneous calls on the same radio frequency. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 MHz or 1800 MHz frequency band. GSM was first introduced in 1991. As of the end of 1997, GSM service was available in more than 100 countries and has become the de facto standard in Europe and Asia.

CDMA stand for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use TDMA, CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence. CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time, and it is the common platform on which 3G technologies are...
