3 1. Purpose The satellite communication systems used in the local goverunments operated by the Local Authorities Satellite Communications Organization (hereinafter called the LASCOM ), must be renewed several years later. We think that we must obtain data to prepare basic designs and the like by performing demonstration tests with actual equipment for candidates of a system to be introduced as a first step to prepare basic design documents, equipment specifications, operation procedures, etc. for installation and maintenance of equipment to revise the current system. Based on the above, the purpose of this Request for Information (hereinafter called RFI ) is to obtain information about next generation system equipment used in Local Authorities Satellite Communications Network provided by the LASCOM and information about demonstration tests which use the next generation system equipment to refer those information items for the future demonstration tests and equipment procurement. (Reference) What is the Local Authorities Satellite Communications Network? The purposes of the Local Authorities Satellite Communications Network are as follows: (1) Expanding/strengthening disaster prevention/administration radio communications (2) Optimizing administration information transmission (3) Enhancing information transmission from local areas The network uses three transponders of the geostationary satellite owned by SKY Perfect JSAT Corporation. We started operating the network in December, 1991 and currently it is used as the satellite communication networks for prefectures, and firefighting and disaster prevention agencies. Establishing the Local Authorities Satellite Communications Network in all prefectures was completed in 2007 fiscal year and as the largest satellite system with more than 4700 earth stations nationwide in Japan.

4 2. Next Generation System Requirements 2.1. Next Generation System Overview The next generation system consists of the Next Generation VSAT System with IP communications functionality by satellite communications and the Next Generation Video Transmission System connected to the next generation VSAT system as a video baseband equipment. Figure 2-1 shows the next generation VSAT system network model. The next generation VSAT system consists of an aggregate station as a hub, a sub-aggregate station as a redundant station of the aggregate station and VSAT stations (earth stations other than VSAT stations included) which are user side earth stations with startype network topology. Figure 2-2 shows the network model where the next generation video transmission system operated on the next generation VSAT system. The baseband video signal converted to IP with the next generation video transmission system is transmitted with the next generation VSAT system and the user side earth stations (VSAT stations, etc.) have roles of material transmission stations (video materials are transmitted to the aggregate station/sub-aggregate station via TDMA inbound of the next generation VSAT system) and remote stations (data are received as multicast streaming via TDM outbound from the aggregate station/sub-aggregate station). Figure 2-3 shows the earth station configuration model example where the aggregate station/sub-aggregate station (HUB stations) and remote station (VSAT station) facilities are indicated with function blocks. The next generation VSAT system consists of the TDM/MF-TDMA modulation/demodulation function and other IP platform facilities and the high frequency facilities and the next generation video transmission system indicates the baseband facilities connected to the Satellite MODEM facilities. In addition, Figure 2-4 shows subsystems which comprise the next generation video transmission system in the aggregate station/sub-aggregate station. 2
