Abstract
One of the most difficult task for any mobile network operator is to efficiently manage an
increasing number of mobile data users especially in a congested urban areas. These high number
of data users require higher bandwidth and high speed throughput. To overcome these problems,
high capital investments are required which are not economically viable. Mobile network operators
are forced to see another alternative to solve the problem by using mobile data offloading
technologies. Mobile data offloading is one of the technique to efficiently handle the growing
mobile data traffic by offloading cellular data traffic to other complementary networks. This will
decrease the burden on mobile network operators and increase the capacity of data network.
Collected data from ethio telecom shows that there is high number of mobile data traffic usage in
3G network that creates network congestion. Currently in Ethiopia ethio telecom solves the
problem by upgrading cellular network to 4G/LTE, using smaller cell/sector method and upgrade
cellular network by adding base stations/transmitters and enhance software resources. Since the
number of peoples in the urban areas like Addis Ababa are increasing dynamically, it is difficult
task for ethio telecom to manage rapid growth of mobile data usage using the above techniques
only. Hence offloading cellular network to other complementary network provides ethio telecom
an advantage to enhance the data network capacity easily.
This thesis also proposes Wi-Fi offloading technique as one of the alternative way to solve mobile
network congestion problems in a congested urban areas in Addis Ababa city Addis Ketema area.
The thesis also shows how Wi-Fi offloading will improve the capacity of the whole mobile
network using Atoll simulation tools and presents options on the technical integration of Wi-Fi
and cellular network. And finally the paper shows the challenges and future works of Wi-Fi
offloading in Ethiopia. The simulation result shows that after offloading a percentage of 3G data
traffic to Wi-Fi network the required grade of service for both voice and data improved.
