NEC: Software Defined Radio for Self-Defense Forces: Sending and receiving emails and displaying location
NEC:
On June 21, a briefing session on “outdoor communication system” was held at the Tokyo Fuchu Plant for the media of about 60 companies.
From this year, the Ground Self-Defense Force has introduced the “outdoor communication system”.
New outdoor communication system:
This is a new outdoor communication system that uses software signal processing to replace wireless communication that was previously processed by hardware.
Software defined radio:
As it stands, communication was performed using different devices depending on the type of wireless.
With the new software radio, a software installation can accommodate different types of radios.
Compatible with various radios:
For example
Normally used as a radio for the Ground Self-Defense Force,
In the event of a disaster, you can use the disaster prevention radio used by the local government.
Communication with US military is also possible:
Areas and SDF personnel can communicate directly.
played an active role in the Great East Japan Earthquake.
In the future, it will be possible to operate it jointly by the Land, Air, and Air Self-Defense Forces and communicate with the US military.
NEC Public Business Unit:
At the press conference, he said, “Software radios were effective in reducing costs and miniaturization.”
Low cost and miniaturization:
In the conventional wireless device, it is necessary to prepare a device for each communication network.
With a software defined radio, one unit can support any number of communication networks.
Tablet device: Android
The big change in operation is the newly added “tablet terminal” to the wireless device.
The tablet device runs on Android, and almost all operations are possible.
Sending and receiving emails and displaying maps:
Location information using emails and maps,
Supports data communication.
Traditional radios rely on voice to tell you where you are.
With the new radio, you can use a tablet to inform you of the location using maps and pictures.
demonstration:
Information marked on the map is wirelessly skipped and displayed on other terminals.
Self-defense personnel can use wireless devices as if they were smartphones.
Since the operation is done on the screen, it is possible to eliminate the buttons and switches from the transceiver itself.
Autonomous decentralized network: (Ad hoc)
When communication is cut off from the access node, which is at the center of the communication network, “a mechanism that automatically establishes a network between communicable terminals”
Allows mutual communication within the unit even when the unit is far away from the base.
This communication is mainly used for defense applications.
Constructed a mechanism that does not cause IP network delay.
This is of paramount importance when operating weapons.
Even if the network conditions change, the delay time and transmission capacity are guaranteed by the technology that selects the communication path optimally and the priority processing technology.
Used for private business:
Train radio is currently in operation and has been introduced to Odakyu Electric Railway.
Research has shown that software defined radio is in demand overseas as well.
In the future, we are thinking not only in Japan but also overseas.
