| dc.description.abstract | Quality of Experience (QoE) is a concept which represents measuring of end-to-end performance of a service from a
user perspective. This research presents the study of QoE offered by mobile network operators in Kenya. An android
prototype application was developed to benchmark user experience by way of making voice calls, internet sessions
and capturing signal strengths. In total, we analyzed 3,178 voice calls, 682 internet connections and 1,266 signal
strengths measured in nine major towns in Kenya. Parameters measured in voice calls included: Completed Call
Rate, Call Setup Success Rate (accessibility to the network), Dropped Calls (call retainability), Blocked Calls and
Call Setup Time. Parameters measured in internet calls are: File Download Speed, File Upload Speed, Network
Latency and Web Browsing Time. The results from the study enables consumers to be able to make informed
decisions while using any service offered by mobile network operators and also be able to compare service level
agreed between themselves and service operators. The results provide the regulator alternative ways to understand
the state of services provided by the mobile network operators and compare against what they promised when they
were issued with the license to operate. Mobile network operators may also use the results by cushioning themselves
against legal and regulatory pressures by how customers experience services offered. This study contributes to the
understanding of performance of services provided by mobile network operators and use of smart phone applications
to measure performance of the services. Finally, it suggests that having better signal strengths and network latency
does not guarantee you a better quality of experience. We recommend that the regulator not only checks if mobile
network operators meet key performance indicators related to voice but also those related to data (internet).
Currently Communication Authority of Kenya (CAK) does only for voice. | en_US |
