North Carolina meter manufacturer Sensus has announced it is using a trial in urban Japan to demonstrate the effectiveness of long range radio technology for smart metering applications.
Sensus said in a statement that the aim of the test is to show connectivity and performance of long range radio working at 280MHz in dense urban areas of the capital Tokyo for advanced metering infrastructure (AMI) systems.
Communication for urban AMI
In Japan, the 920MHz low power radio band may face challenges as the number of devices using the shared spectrum increases, making long range radio an attractive option, said Sensus in a statement.
Toshiyuki Naka, country manager for Japan at Sensus, said: “Long range radio has been proven to provide dedicated, resilient and secure network infrastructure to utilities, municipalities and cities around the world.
“It offers the reach, coverage and stable connectivity that simply can’t be achieved by mesh or cellular networks.”
Sensus is partnering with Japanese communications engineering company MIRAIT Technologies for the trial, which kicks off in Q1 2015.
Results will be shared with a range of groups, including utility companies, commercial organizations, potential partners, local government and regulators.
Application in residential meters
Sensus is known for using long range radio technology in its meters with the launch of a new residential meter in August 2014 fitted with the communication mode.
The iConA Generation 4 allows utilities to turn off and on all radio frequency transmissions remotely.
The company says by deploying long range radio technology, the FlexNet communication system acts as a two-way communications highway for investor-owned utilities, municipalities and electric cooperatives.
Sensus uses the communication technology in its iPERL residential water meters that to better monitor and control water leaks.
The company is also providing the core communications technology to support the UK smart electric and gas meter rollout.
