One-seg Mobile TV Saved Many Lives during the 3.11 Disaster A huge earthquake struck on March 11 in the north-east area of Japan. Right after the end of the violent shakes caused by the earthquake, Mr. Takahashi, Senior Managing Director of TOYO KNIFE, an industrial cutlery company located in Miyagino district, Sendai City, immediately turned on the one-seg TV function on his mobile phone in his office, to which the power supply was cut off. He got an emergency warning alarm for a tsunami on his one-seg TV (mobile phone). Regrettably his office was located very near the port (about 500m from Sendai-Shiogama Port), so he and other staff did not have much time to evacuate, but 100 people managed to rush to a shelter on a hill. By the time they arrived at the shelter (Tagajyo Public Cultural Center) at 3:30 pm, the TOYO KNIFE office and factory had been completely destroyed by the long-lasting, huge tsunami. Mr. Takahashi said “ We couldn’t watch TV because of the power cut, but we could get information on the disaster quickly from our one-seg TVs.”
Note: the one-seg TV function on a mobile phone is powered by the phone’s battery

Two policemen saved 40 lives from the train with the tsunami warning alarm from mobile TV(one-seg) right after the earthquake occurred at 14:46 on March 11, 2011.They got a tsunami warning alarm from the passengers mobile phone with TV when checking if everyone is fine in the train. They quickly decided to lead the 40 passengers to the hill to avoid the disaster of tsunami. All passengers were safely evacuated from the tsunami area before the tsunami struck the train.
The cars of train derailed off the track by huge tsunami waves. (March 12, 2011)

Media used at the time of earthquake
33
Immediately after the earthquake, the usefulness of mobile phones, mobile phone messages and terrestrial broadcasts received higher evaluation and at the end of April, the evaluation of the usefulness of mobile phones, mobile phone messages and terrestrial broadcasts exceeded that of radios.
During the period from the occurrence of the earthquake until the end of April, the websites and search sites of administrative agencies and news media received higher evaluation
At the time of occurrence of the quake, AM radios received the highest evaluation (60.1%) followed by FM radios.
At the time of occurrence of the earthquake
Immediately after the quake
Until the end of April
Immediately after the earthquake, radios were the only means to obtain information. However, radios were insufficient to grasp the actual state of damage in the area and it took a long time to know of the enormous damage caused by tsunami. We were unable to know who was doing what and felt highly anxiousness.

TV stations suffered significant damages and 120 stations in eleven prefectures were out of service. As there was no power supply in the large part of the disaster areas, both transmitters and receivers were not usable.

Mobile TV in the Evacuation Center
(Summary from Sankei Shimbun (major Japanese national newspaper), June 24, 2011)
Many people watched mobile TV in the evacuation center. As power was disrupted, mobile TV was very important information source for the people in the disaster area.
36
Local Disaster FM stations
The Studio of “Natori Saigai(disaster) FM” established at Natori City office building, Miyagi prefecture
Radio also played a very important role in the disaster area, as many radio receivers work with batteries and people can receive information even during a power outage. MIC also provided 10,000 radios to the disaster areas free of charge. Temporary radio stations have been set up which have been actively providing information needed at local level. Many volunteers and local government officials contributed to the operation of such local radio stations.

Digital signage network is effective tool for information provision at the time of disaster. After the earthquake, all the train services stopped and there was terrible traffic jam in Tokyo. About 5 million people were not able to go home. Digital signage system was used as media to provide information.

Some car navigation system gathers driving information from navigation unit and the system consolidate information and send traffic information to users. On March 14, Honda released this driving information gathered through their navigation system on the website. This information became instantly available through Twitter and Facebook. Many people thanked that “We could deliver relief supplies”, or “We could reach family and relatives” by using this system.

R&D for relieving service congestion in the mobile network caused by disaster
Under a disaster, a vast amount of voice calls are made in mobile carrier networks and an unprecedented level of traffic (congestion) is generated.
New network technology applicable to current and next generation networks to relieve service congestion in the network will be explained.
R&D on the reconfigurable communication “resource unit” for disaster recovery
A “Resource Unit” which can meet the wide variety of communication demands under a disaster will be explained.
The “Resource Unit” can be transported by means such as a high-mobility vehicle, can be connected to surviving communication networks, and can reconfigure the damaged networks immediately.
Developments of next generation VSATs effective for severe disasters
Even in the event of a destroyed ground communication infrastructure by disaster, easy and prompt establishment of satellite communications networks secures alternative communication paths.
New multimode VSATs that can connect to heterogeneous satellite systems using easy procedures in a disaster will be explained.
