Final Report Chapter 10 Assessment of the Project The traffic to and from most telephone subscribers (fixed-line and mobile) will flow through the backbone network and the Metropolitan network, the capacity of which will be increased through the development of the communications infrastructure. The increase in capacity will enable the net increase in the number of telephone subscribers (fixed-line and mobile) to be covered. The development of communications networks in small and medium-sized cities will also enable the net increase in the number of telephone subscribers (fixed-line and mobile) to be covered. The LTE (Long Term Evolution) infrastructure will mainly result in a net increase in the number of Internet subscribers, and also lead to a net increase in the number of mobile phone subscribers. Therefore, the net increase in the number of telephone subscribers (fixed-line and mobile) will be used as the main index for assessment of communications infrastructure development. 2) How to determine the target value As described in Chapter 7, the capacities to be increased in this project are as follows: Backbone: 500Gbps Metropolitan network: 700Gbps (Yangon; 300 + Naypyitaw: 100 + Mandalay: 300) However, the average traffic capacities required to meet the demand on achieving a diffusion rate of 80% are as described in Chapter 7: Backbone: 420Gbps (419.50Gbps)×2 = 840Gbps (non-ring structure is assumed, and the capacity is half as high as the ring structure.) Metropolitan network: 45 to 250Gbps in each city As described above, the Metropolitan network will provide a supply capacity of 700Gbps (Yangon 300 + Naypyitaw 100 + Mandalay 300) for the demand capacity of 45 to 250Gbps in each city so as to obtain a balance between supply and demand. Demand can be satisfied 100%. As the supply capacity of the backbone network is 500Gbps against a demand of 840Gbps (non-ring structure), approximately 60% (500/840) of the total demand will be satisfied. If the calculation method to cope with the bottleneck (conservative calculation) is used, the net increase in the number of telephone subscribers (fixed-line and mobile) allowable to maintain the current level of service is: 48 million×0.6 = 29 (28.8) million This number is deemed to be the target value. (The total demand= 48 million, as shown in Table 5.2-7.) This target number includes the net increase in the number of telephone subscribers (fixed-line and mobile) that will result from the addition of the LTE systems and the development of communications networks in small and medium-sized cities. 10-2
