Prompt Restoration of Communications Services

Leveraging mobile equipment to restore services

Power supply vehicles

When communications building and wireless base station backup power sources (batteries, engines) have ceased functioning after prolonged grid power outages, we dispatch power supply vehicles capable of supplying up to 2,000 kVA (equivalent to the electricity consumption of several hundred households) to keep the facilities running.

Power supply vehicles

Portable satellite equipment

These units use satellite links to provide Internet access and connect emergency use public phones deployed at evacuation centers.

Portable satellite equipment

Portable digital wireless units

When trunk lines connecting communications buildings have been damaged, these units are deployed on both sides to restore transmissions between the buildings as a stopgap measure until lines are repaired.

Wireless IP communications vehicles (nicknamed "WiFi Car") and communications rescue vehicles

We provide prioritized calling under Japanese law to assist in disaster response and recovery, and in the maintenance of public order.
Because prioritized calling transmissions are given precedence over ordinary calls, they are less likely to be affected by network congestion in the aftermath of the disaster.

Satellite entrance mobile base stations

These satellite circuit-equipped vehicles are mobilized when an earthquake or other disaster strikes to provide coverage in areas in which mobile phone communications have been disrupted.
