MEASUREMENT AND ANALYSIS THE QOS & KPIS OF CELLULAR NETWORK OPERATORS AT CAPITAL OF YEMEN SANA`A

Key performance indicators (KPIs) and drive tests are used to evaluate the performance of an operational cellular communication network. These counters are converted into a more readable way. The objective of this paper, study KPIs and Quality of Service (QoS) of the performance of the cellular network in the city of Sana'a, the capital city of the Republic of Yemen. This paper discusses three subjects. In the first section Measurement and Analysis the parameters for circuit-switched Voice services and packet-switched data services which is one of the major KPI, which should be optimized to improve QoS, in the second section, Measurement and Analysis the Received Signal Level And Quality of cellular stations. In the third section Measurement and Analysis, the Called Passive Method. Hence, it can be concluded that it has been analytically proved that we can optimize an existing cellular network using different methodologies and fine parameter tuning to offer remarkable QoS to the end-users, despite its positive results. This research in the Republic of Yemen is considered to be, a rare research and it can be said from the first researches on this subject in the Republic of Yemen.
