Project Deliverable/Outputs 5.1 EBAN System There are 2 main sub systems that are needed build complete EBAN solution. First is communication platform. This platform consists of two parts, backhaul communication part and access communication part. For both parts, team used wifi technology as the solution, but works in different frequency. For backhaul, the frequency is 5.8 GHz and for access is 2.4 GHz. Second sub system is the balloon platform, which is used as low altitude platform station. To maintain the stability and height of the platform, team used two balloons connected with 2 meters hub and tethered using ropes. Each balloon has diameter about 6 meters, thus both can lift payload up 40 kg 500 m height. This solution is ideal considering the coverage up 24 km diameter, which is large enough covers the communication system with broadband capability. 5.2 Enhancement of HRM Competency All researchers involved in this project have obtained some advantages improve their technical capabilities and project experiences, especially in scope of low altitude platform station. And also the team got the experience on how deal with people, especially whom are not related IT in their daily activities. 6. Field Trial

12 In order examine the EBAN system and get some data from the measurement, team performed the field trial of the system. The project trial is done in Sulaeman Airport, which is one non-operational airport in Bandung, operates by Indonesian air force. After completion the project, all team members consider continue the research of the system, enhance the capability and stability. 6.1 Objectives The main objectives of the project trial are: Examining the performance of EBAN system. Performing system testing, including functional tests, response time and stability of the EBAN system. Doing measurement get the data of stability, performance, duty cycle and other related facrs. 6.2 Schedule of the EBAN Trial The EBAN system project trial was held on May 15 June 30, The trial is divide in two phases, 1 week on May and other on June. During the trial all team members performed functional and stability test make sure that EBAN system is ready act as a communication platform. To get some data, team using measurement device capture the traffic that flow from user device access point in balloon platform. In second phase of the trial, Japanese team jointed do measurement and also gave the suggestions get more accurate data. 6.3 Place of Trial Place of trial is mainly in Bandung, in Sulaeman Airport. Sulaeman airport is one of airports in Bandung, operates by Indonesian air force. This airport is not use as a commercial airport, because the location is near the public s house. Regularly, the airport is used as a landing area for parachute trainee. 6.4 System Configuration of the Trial Based on the original system configuration, we modified a little bit, so the connection from satellite goes direct the internet, where the measurement was done by accessing the content from internet.

13 Internet 6.5 Trial Analysis Summary Based on the trial, the summary analysis of the system is as follow: Assumptions: - Antenna model: ITU envelope model for Patch Antenna with max gain of 6 dbi. - Transmit level of 26 dbm. Using those assumptions, team summarize the result as follows PDF of EBAN attitude

16 Coverage of EBAN System The detail analysis can be read in the separate document, attach in Annex-2 Document Analysis of EBAN. 7. Impacts of the EBAN Project Some advantages of the EBAN system are: For team member: Some advantages for the team are: a. Having a simple, easy, fast deployment, and in-expensive communication system for emergency/disaster area with broadband capability, provides video, voice and data communications. b. Using general CPE with wifi capability connect the system. But there is a repeater needed strengthen the signal. c. New experience for the team research new communication platform that can be implemented in the air using low altitude platform station. d. With the system, there is wide-open possibility for others create service and content, specific for disaster area.

17 For Non-Government Organization Some advantages for NGO are: a. The system will be part of the bigger system as a solution for disaster area, especially for broadband implementation. b. To show the government of Indonesia, that there is new platform, which is low altitude platform station, that can carry communication system in the air serve for restricted area. c. The system is stable enough as a data carrier, thus many application can be served include video and real time communication. 8. Project Sustainability In order ensure the continuity of the project, all team members have considered continuing the research of EBAN system. Some efforts ensure the sustainability of the implementation of EBAN system are: Improvement of the EBAN system based on the trial measurement; such as enhance the stability of the platform, improvement of the antenna and securing the communication part avoid fraud. Implement application that is needed most for disaster victims, for example victim management, video streaming application and voice over IP. These applications should be light and very easy use. In addition, the EBAN system is very needed as a completion part of disaster management system ensure that communication part can be implemented very easy and fast. So the sustainability of the implementation of the system based on the market need is very promising. 9. Lesson Learned Some lessons learned from this project are as follow: a. The implementation of IT is very important for human being, not only for people live in the city, but also in the disaster area. And we realized that the distribution of IT knowledge is not equal in every area. Because of that, IT related project should be developed gradually in more areas. b. Collaboration among researchers from some different locations can be effectively accomplished electronically via both Internet and telecommunication facilities. c. Intensive coordination between team members, non-government organization and also people is very needed make sure that the implementation of the system is running well. d. The problems/limitations of this limited EBAN trial may be in the area of: o Stability of the balloon platform for a specific height, where there is strong wind can happen anytime.

18 o Client CPE for wifi. Because for long-range distance, regular CPE can not be used, because of signal strength can not reach the station. o Security of the system during internal communication, where there can be fraud during the connection. o Lack of team s knowledge about low altitude platform station technology, especially this is the first trial for that. 10. Future Plan a. All team members consider do further research regarding low altitude platform station and communication system, that can give more stable solution from interruption of wind, whether and flying living (bug, bird). b. In future implementation team agree collaborate with non-government organization that has task as a disaster work force. In this collaboration, EBAN system will be used as a main solution solve communication problem between center of coordination and team in the field. c. This model of low altitude platform station is the first research in this area, thus team consider publish the result in the national and international forum, get the input enhance the system and also get opportunity for wide implementation. 11.
