Multichannel Multipoint Distribution Service (MMDS) is one of the currently used FixedrnWireless Broadband (FWB) systems that provide multichannel broadcasting, broadband internetrnand other interactive services. It works mostly at 2.5-2.7 GHz frequency band through terrestrialrnpropagation. As its name implies, it provides multiple television channels because of its highrnfrequency band. It is more cost efficient than cable and satellite broadcastings for relatively smallrncoverage areas like cities and towns.rnAddis Ababa is a city with a population size of more than 4 million that have complex linguistic,rncultural, religious and ideological varieties. The city is the site for many diplomatic communityrnand hosts many international organizations. Moreover, it accommodates many internationalrnconferences. Addis Ababa, which has now only few television channels, needs to benefit fromrnbroadcast communication systems like MMDS that can provide far more number of channelsrnwith relatively lower cost to foster its national and international values for maximum benefit.rnIn this thesis, coverage planning of MMDS, which is an integral part of the entire planning, isrncarried out for Addis Ababa. In coverage planning, propagation models are used to predict thernpath loss at a certain distance from the transmitter site considering terrain and otherrnenvironmental effects. The planning involves two steps; firstly, system dimensioning is donernusing the Institute of Electrical and Electronic Engineering, IEEE 802.16 (Stanford UniversityrnInterim) model. Secondly, detail planning is accomplished using the InternationalrnTelecommunications Union Recommendation, ITU-R P.1546-5 model.rnIn coverage planning, the important parameters are the transmitter output power, number ofrntransmitters needed, locations of transmitters for maximum coverage, and the positions andrnoutput powers of repeaters to cover small shadowed areas. Most of these parameters arerndetermined based on the propagation models used.rnThis work took 10 high altitude locations in the city as candidate sites for maximum coverage.rnThe result shows that one 70 meter transmitter with 57dBm output power located at a mountainrnaround Lebu area (South-Western part of Adds Ababa) and a 25 meter repeater with 32 dBmrnMMDS Coverage Planning for the City of Addis Ababa Page Vrnoutput power located around Country Club Developers Homes (North-Eastern tip of AddisrnAbaba) can cover 96.14% of the area of the city, which is satisfactory coverage.rnKeywordsrnMultichannel Multipoint Distribution Service, Propagation models, Broadcasting, Coveragernplanning, System dimensioning, detailed planning, ITU-R P.1546-5 model.
