Final Report Chapter 7 Outline of Scope of Works (4) Equipment to be introduced Details of the fiber optic cables planned to be introduced in each city are shown in the optical cables column in the following tables in Section 7.1.2. (a) Table 7.1-1 Yangon Metro New Fiber Routes (b) Table 7.1-2 Naypyitaw Metro New Fiber Routes (c) Table 7.1-3 Mandalay Metro New Fiber Routes At the same time, to increase the transmission capacity, the following DWDM transmission equipment will be introduced in each city’s metro network. (d) Yangon：100Gbps x 3 wavelengths, 10Gbps x 3 wavelengths (e) Naypyitaw：100Gbps x 1 wavelength, 10Gbps x 3 wavelengths (f) Mandalay：100Gbps x 3 wavelengths 7.1.4 LTE expansion in three metro cities (1) Current situation In Myanmar, LTE access networks will be established by construction of 17 (Node B) base stations in Yangon, 28 (Node B) base stations in Naypyitaw and 5 (Node B) base stations in Mandalay under the Project for Urgent Improvement of Communication Networks implemented with Japanese Government grant aid which was completed in December 2013. (2) Necessity (Relevance) To effectively utilize the cities’ LTE base stations constructed under the Project for Urgent Improvement of Communication Networks mentioned above and to meet future growth in data communication subscribers, it is desirable to build as many more LTE base stations as possible and expand the subscriber capacity. To design the required number of (Node B) base stations in each city, the functions of each city were categorized into city center, intermediate area and residential area and the area ratio was calculated. The number of LTE base stations (Node B) required in each city calculated from the results is shown in Table 7.1-4. The expansion plan for each city is shown below. (a) Yangon：17 → 615 (Node B) base stations (b) Naypyitaw：28 → 465 (Node B) base stations (c) Mandalay：5 → 420 (Node B) base stations Compared with fixed-line communication services, LTE communication services have the following advantages and will be an effective means of achieving early services. 1) The construction period for subscriber access and costs can be reduced.  Subscribers can connect to the internet using an all-purpose Wi-Fi adaptor simply by signing a contract with the network provider. 7-18
