Nagaoka University of Technology: Drone using 169 MHz: Expanded communication range to 5 km
-Nagaoka University of Technology and ShinMaywa Industry-
Using the frequency band 169 MHz, we succeeded in a drone wireless communication experiment at Sado Airport.
Uses a new frequency band of 169 MHz that can be used for drone operation.
We verified that there were no problems compared to the conventional frequency.
Conventional frequency: 2.4 GHz
Drone operation generally has the same frequency as Wi-Fi equipment, such as 2.4 GHz.
It was easily affected by the building and had the drawback that communication could only reach about 600 meters.
This frequency: 169 MHz band
The 169 MHz frequency has been approved for use since August 2016.
The communication range has expanded, and the communication range is as wide as 5 kilometers.
Maneuver a fixed-wing drone in the 169 MHz band.
This is the first time in Japan that we have investigated how radio waves are transmitted.
Via base station-relay station:
In the experiment, in addition to the base station, a relay station was also installed on the shore of Lake Kamo in Sado City.
Succeeded in remote control and information communication via a relay station.
Install a relay station on the ship:
If you install a relay station on the ship, you can fly at sea from land.
Since it can fly over a wide range, it can also be applied to the observation of air pollutants.
