Final Report Chapter 7 Outline of Scope of Works 7.1.5 Network plan for towns along the backbone network connecting the three metro cities (1) Current situation In Myanmar, the density of communication services at national level is low, but there is also a huge regional divide and the density of fixed-line telephones outside the three metro-cities is especially low. With regard to the internet, although some broadband services are provided by ADSL or domestic satellite communication, density of services is far from that in three metro cities. (2) Necessity (Relevance) Improvement of communication services in small regional cities is an urgent issue for the development of Myanmar by the political and economic reforms currently promoted by the Thein Sein administration. Construction of a communication network and improvement of communication services will be easier in those small cities located along the backbone network between the three metro-cities than in other provincial cities and suitable for the construction of model case for telecommunications in local cities. Therefore, by selecting a sample cities from the mid and small cites surrounded in backbone network of 3 Metro cities and by constructing internet communications network in those cities, model case of telecommunications network in local cities for future shall be built. Average traffics per subscriber from Bit Stream shown in Table 5.2-7, are projected as follows, ・Internet speed per user of fixed broadband: 57.8 kbps ・Internet speed per user of mobile phone: 11.57 kbps These cities being classified small cities, from Table 5.2-8, Subscriber Number Forecast ・Voice subscriber penetration: 96.0% ・Data subscriber penetration: 60.0% (Fixed broadband subs. 3% (= 60 % x 1.5/30), Mobile phone subs. 57% (= 60% x 28.5/30)) Then, theoretically, per 100,000 population ・mobile subs. data: 11.57 (kbps) x 100 (thousand) x 0.57 = 659.5 (Mbps), Considering average/max. Ratio of 1.5, the necessary capacity is as follows: ・mobile subs. data: 659.5 (Mbps) x 1.5 = 989.2 (Mbps) ≒1,000 Mbps Where, supposing maximum radio transmission capacity of 200 Mbps per LTE, 5 LTEs (1,000/200=5) shall be provided, i.e., 1xLTE shall be provided for 20,000 of population. For the fixed broadband line, FTTx shall be applied and the capacity per 100,000 population is calculated as follows: ・Capacity for fixed broadband subs.: 57.87 (kbps) x 100 (thousand) x 0.03 x 1.5 = 260.4 (Mbps) 7-22
