Draft Final Report 7.1.12 Chapter 7 Outline of Scope of Works Thilawa SEZ Circuit (1) Current situation Optical fiber equipment with a transmission capacity of 1Gbps and an LTE base station were installed at Marine University under the Project for Urgent Improvement of Communication Networks implemented with Japanese government grant aid by December 2013, but other communication equipment has yet to be upgraded. (2) Necessity (Relevance) Thilawa SEZ is currently in the planning stage and plant layout in the area and the state of infrastructure development are not clear, but in order to provide communication services promptly upon the opening of SEZ, effective use of the current communication infrastructure is desirable. The current situation is described from that perspective. It is meaningful to strengthen the functions of the transmission equipment at Marine University, which was installed under the Project for the Urgent Improvement of Communication Networks implemented with Japanese Government grant, while it would be useful to install fiber optic communication lines to the Thilawa SEZ boundary. Fiber optic cable to be laid to Thilawa SEZ boundary, transmission equipment to be connected, routers and switches shall all correspond to the capacity of 10Gbps. The capacity shall be judged adequate for the following reasons: Average traffic of one subscriber from the communication speed shown in Table 5.2-7 is; ・Voice by mobile telephone: 0.06 (kbps) ・Data communication by fixed broadband: 57.87 (kbps) ・Data communication by mobile telephone: 11.57 (kbps) Thilawa SEZ populated approx. 334 thousand, is classified as a small city from the Table 5.2-8 shown in Chapter 5 and subscriber predicted is; ・Voice subscriber: 96 % ・Data subscriber: 60 % (Fixed broadband:3 %, Data mobile: 57 %) The traffic data of Thilawa SEZ populated 334 thousand will be theoretically calculated as follows: ・Voice: 0.06 (kbps) x 334 (thousand) x 0.96 = 19.2 (Mbps) ・Data mobile: 11.57 (kbps) x 334 (thousand) x 0.57 = 2,202.7 (Mbps) ・Data fixed broadband: 57.87 (kbps) x 334 (thousand) x 0.03 = 579.9 (Mbps) ・(Voice + Data) x 1.5 (Ave/Max Ratio) = 4,202.7 (Mbps) The equipment facility, however, shall have a twice capacity of calculated data of 4,202.7 (Mbps), that is, 8.405Gbps, which is expected to be concentrated the traffic in day time. 7-40
