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 - 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.
