Japan Telecom Recovery - NTT's emergency vehicle lineup, 3/20

, ,

As a mother of 2 young boys, I have seen so many "work vehicles" videos with them, and I have realized how much that experience influenced my mind these days.  Every time big vehicles like "Hyper Rescue Special Fire Truck" come out, I cannot help but get excited. So here is a little share of "big work vehicles" in telecom industry.

NTT Public Relations was kind enough to share photos of the emergency vehicles, utilized by NTT East (local carrier) and NTT DoCoMo after the earthquake.

Japan Telecom Recovery - ITU deploys Satellite phones, 3/16

, ,

Not only DoCoMo and KDDI, but also ITU is bringing in more satellite phones to Northern Japan. Geneva, 16 March 2011 — ITU has dispatched emergency telecommunications equipment to areas severely affected by the tsunami that struck the coastal areas of Japan following Friday’s devastating earthquake measuring 9.0 on the Richter scale.

ITU has deployed 78 Thuraya satellite phones equipped with GPS to facilitate search and rescue efforts along with 13 Iridium satellite phones as well as 37 Inmarsat Broadband Global Area Network terminals. An additional 30 Inmarsat terminals are also ready for dispatch. The equipment can be charged by car batteries and are also supplied with solar panels to enable operations during power outages....(see below for full text)

Japan Telecom Recovery - Web sites for rescue, 3/16

,

Many web/net service players are working hard to support the recovery effort, by providing critical information for affected people.  I already have reported about the emergency bulletin board service by telecom carriers, so here are some other useful ones. "Google Person Finder":  Simple service to upload and search whereabout of people.  Available in Japanese, English, Korean, Chinese (mainland/Taiwan), Portuguese and Spanish.

"Google Crisis Response":  Total portal site for related information, including government announcement, medical info, emergency bulletin board access, rolling blackout map search service, Red Cross donations and many more.  Available in Japanese, English, Chinese (mainland) and Korean.

"Google/Honda/Pioneer Road Map":  This is pretty amazing.  The map shows the blue mark on roads where actual automobile traffic happened on the previous day, grey shows roads with no traffic, informing which roads are open for automobiles.  It utilizes the GPS data uploaded from Honda Internavi Premium users' navigation devices, service operated jointly by Honda and Pioneer.

"Google Person Finder BB Photo Album":  Photos of person finder bulletin boards are shared.

"OLIVE":  Non-profit wiki site to share useful ideas for everyday life under the crisis, such as how to keep you warm with newspaper and stylofoam, how to cope with toilet situation, map of food distribution locations, etc.  Available in Japanese, English, Korean and Chinese (mainland).

"Yahoo! power info page":  Shows detailed info about rolling blackout, and provide tips to save energy.

"Anti rumor info":  Blog "Ogigami-Shiki" and "Dema Chain Mail" list the typical false rumor on the net regarding the quake, and show the facts against them.  There are some serious false rumors about relief operations, environmental polution etc., and some donation scams have started to pop up on the Net.

My friends over at AMN have gathered and auto-ranked the sites (utilizing data of social book marks, Facebook/Twitter mentions etc.).  Some corporate sites, such as TEPCO and Tokyo Metro (subway), are included on this ranking as well.

Japan Telecom Recovery - Another quake, another disruption, 3/16

,

At 3/15, 10:31pm, another quake struck eastern Japan.  This time, epicenter was Shizuoka prefecture, and the magnitude was 6.4 - equivalent of New Zealand earthquake a few weeks ago.  Oddly, nobody takes it seriously in Japan now - it is just another tremor. Due to this quake, some more telecom service became unstable.  NTT DoCoMo placed 80% traffic restriction on calls to Shizuoka, Yamanashi, Kanagawa prefectures, and some parts of Tokyo and Aichi prefectures right after the quake.  However, they lifted the restriction on 3/16, 0:22am.  Current restrictions are effective in Miyagi, Iwate and Fukushima (up to 50%), Ibaragi (up to 30%), Gunma (up to 60%) as of 3/16, 11:34am.

Unfunctional cell site number is down to 1970 sites as of writing.  No effect was made by the Shizuoka quake.

Japan Telecom Recovery - Mobile cell sites deployed, 3/15

As previously reported, mobile operators are working hard to recover their cell sites. Source:  Nikkei Newspaper 3/15

DoCoMo, whose 6720 sites damaged at the peak on 3/12, has reduced the unfunctional sites down to 2130 by 5pm on 3/15, which corresponds to 20% of total 11,000 sites, orignially deployed in Tohoku area.

KDDI's damage was down from 3800 to 1500 sites, Softbank from 3786 to 1157 sites, both compared to the peak of the damage.

Damage by the tsunami will take a long time, and the carriers are deploying mobile cell sites to the emergency shelters.  As of the time of reporting, DoCoMo has brought in 30 trucks, KDDI 5, and Softbank 1.

Still, traffic restriction is in order, with DoCoMo 80% restricted and KDDI 20%, as of morning of 3/15.  I suppose it is because DoCoMo has a lot more customers in the area.
