4. Problem Statement
Despite of the availability of several mobile telecom network companies in Yemen, the quality of services provided by those companies has been still unsatisfied.
Although, those companies spend a huge sum of money to improve quality of service (QOS), however, the progression is slow.
There are different methods available in literature to improve the efficiency of sharing the companies’ infrastructure. Nevertheless, currently there are no available studies specifically discuss the Mobile Telecommunication Network Infrastructure Sharing in Yemen.
Therefore, there is a vital need to find an efficient method for expanding the mobile networks in Yemen and maintaining limited of towers depending on infrastructure telecommunication sharing.

5. Research Aim & Objectives
The aim of this study is to enhance the infrastructure sharing of Telecommunications companies in Yemen (ISTC) and the resulted quality of service (QOS).
To identify the enablers and obstacles of the application of Mobile Telecommunication Infrastructure Sharing (M.T.I.S).
To determine how the current infrastructure sharing of Mobile Telecommunication can enhance the (QOS).
To develop a framework for Mobile Telecommunication Infrastructure Sharing in Yemen to adapt the new technology such as (4G &5G) for future to improving the (QOS).

6. Research Scope The study will focus on:
1-Current Mobile Network Infrastructure Sharing for mobile network operators in Yemen (operators target ,MTN,SABFON ,YEMEN MOBIL,Y-TELECOM).
2-Infrastructure Sharing for second generation called Global System for Mobile Communication (GSM) and the third generation called Code division multiple access (CDMA),(2G,3G ).
3-On how to accommodate the new technologies in wireless network, such as 4G & 5G.
