Overview
Our earth stations can be easily set up and can quickly start performing their mission in an area stricken by a disaster. Our terminals ensure a transmission speed of up to 384 kbits/s for the return link, which can simultaneously carry ten VoIP (Voice over Internet Protocol) channels. Their transportability has been greatly improved through equipment miniaturization and weight reductions. Moreover, our remote uplink access test program and two satellite auto-tracking antennas will dramatically improve the operator’s convenience.
Features
- The terminals can be applied to portable earth station systems without concern for network congestion because they use an exclusive frequency band operated by NTT East and NTT West.
- Our terminals are much more portable and convenient compared with the currently available portable earth station system.
- The equipment composition can be configured to suit the stricken area.
- Vehicle-mounted type: Can be installed in a normal-sized car, so it can reach a stricken area quickly to help
restore communications.
- Flyaway type: Easy to carry to a disaster area because it can be broken down and packed into four separate
carrying cases. - Our terminals can start performing their mission in less than 15 minutes owing to the satellite auto-tracking function (compared with 60 minutes at present).
- The uplink access test can be executed by remote control.
Application scenarios
- Free public telephone services and web171 services (Disaster Emergency Broadband Message Board) will be provided to a disaster-stricken area.
- Free public telephone services and Internet services will be provided to an event site.
