Sony’s LPWA

The Connected Future has Arrived

Features

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.

LPWA (Low Power Wide Area) Features

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.

Use cases

Use case 1Ski resort

Mountain activity observation service that makes use of the superior communication range

Problem

Unable to locate family

Solution

Users can determine where family members are skiing. This system can also be used as an accident countermeasure.

Use case 1 Ski resort

Use case 2Maritime watch

Monitoring of ocean equipment, vessels, and offshore fisheries taking advantage of a superior communication range

Problem

Maritime rescue in the event of accidents

Solution

Embedding this terminal in lifejackets can help in locating accident victims.

Use case 2 Maritime watch

Use case 3Ride-sharing

Asset management service in urban areas that makes use of the resistance to interference

Problem

Unable to determine whether there are bicycles in the bicycle garage (when drop-off is okay)

Solution

Users can check how many bicycles are available from a remote location, helping to increase operating rates.

Use case 3 Ride-sharing

Use case 4Drones

Drone position monitoring service that makes use of good mobile characteristics

Problem

Conventional LPWA systems have difficulty acquiring and monitoring objects moving at high speeds (100 km/h).

Solution

Users can comprehend location data, which helps to achieve asset management and safe flight.

Use case 4 Drones
