Sony has newly developed a proprietary LPWA (Low Power Wide Area)-type radio communication system.
This system provides technology for efficiently recognizing situations and environments, and gathering information with ease.
Its greatest features are a long communication range and good mobile performance.
Proprietary technology supports a large number of connected units per base station for high investment efficiency.
Sony LPWA uses precise time information received from GPS satellites and proprietary error-correction technology to receive information from distant mountain and ocean locations with high sensitivity.
Transmission performance of
100 km or more (line-of-sight)
Even when moving at
a speed of 100 km/h
Even in noisy urban
areas with cross talk
a single button battery
Super-high sensitivity realizes long-range communication of 274 km (line-of-sight).
Mt. Hidegadake in Nara Prefecture to Mt. Fuji 5th station
Place a transmitter in a rucksack pocket when climbing mountains.Realizes continuous and stable communication over the extended distance of 150 km.
Mt. Nantai in Nikko City, Tochigi Prefecture to Atsugi City, Kanagawa Prefecture
Realizes stable communication while travelling at high speeds of up to 100 km/h.
Vehicle-borne transmitter to Atsugi City, Kanagawa Prefecture
Mountain activity observation service that makes use of the superior communication range
Unable to locate family
Users can determine where family members are skiing. This system can also be used as an accident countermeasure.
Monitoring of ocean equipment, vessels, and offshore fisheries taking advantage of a superior communication range
Maritime rescue in the event of accidents
Embedding this terminal in lifejackets can help in locating accident victims.
Asset management service in urban areas that makes use of the resistance to interference
Unable to determine whether there are bicycles in the bicycle garage (when drop-off is okay)
Users can check how many bicycles are available from a remote location, helping to increase operating rates.
Drone position monitoring service that makes use of good mobile characteristics
Conventional LPWA systems have difficulty acquiring and monitoring objects moving at high speeds (100 km/h).
Users can comprehend location data, which helps to achieve asset management and safe flight.
