Wi-SUN (Wireless Smart Utility Network) radio equipments have been adopted in smart meters and HEMS controllers in Japan and are in the practical stage. In the future, further development is expected as a means of communication for realizing smart cities and smart grids in Japan and overseas. TELEC provides the testing services necessary for the Wi-SUN radio equipment to acquire Wi-SUN certification issued by Wi-SUN Alliance.
About Wi-SUN
Information and communications equipments that use radio waves, such as mobile phones, have become a familiar existence in our daily lives. Recently, wireless sensors have been embedded into car, home appliance, agricultural machinery, plant equipment, robot, etc., and IoT communications, which automatically exchanges information between things, has become common.
Under such circumstances, the introduction of smart meters, which incorporate small, long-life wireless equipments in various meters such as electric energy meters and gas meters, is going forward in Japan. Wi-SUN HAN (Home Area Network) is a wireless communication standard adopted for networking such high-performance smart meters. Wi-SUN HAN is also used for wireless communication between a Home Energy Management System (HEMS) controller and smart home appliances.
Wi-SUN FAN (Field Area Network) also makes the realization of smart cities and smart grids feasible by forming a large-scale mesh network outdoors. It can be applied to various applications such as smart meters, smart streetlights, parking management, and traffic management, etc.
Wi-SUN is a radio communication standard, based on global standard IEEE 802.15.4g/4e and IPv6, which is led by National Institute of Information and Communications Technology (NICT) with propelling research, development, and standardization. The Wi-SUN Alliance, an international industry organization, is promoting standardization and dissemination of specific applications.

About Wi-SUN Certification
Wi-SUN certification is issued by Wi-SUN Alliance based on test results of an accredited laboratory, which is approved by Wi-SUN Alliance as having the required testing ability, and use of the logo mark of the alliance is authorized by Wi-SUN once the certification is obtained.

Wi-SUN Alliance Certification Test
As for Wi-SUN Alliance certification testing, we conduct two types of tests: the Conformance Test for verifying conformance to standards and the Interoperability Test to Wi-SUN radio equipment Certified Test Bed Unit (CTBU), which is the reference standard approved by Wi-SUN Alliance.
The test is divided further as shown in the table below.

Testing and Certification of ECHONET Lite
ECHONET Lite is the communication protocol standardized by ECHONET CONSORTIUM to establish connections between HEMS (Home Energy Management System) controllers and some electrical equipment in houses.
TELEC has been authorized by the ECHONET CONSORTIUM as Testing Body and Certification Body for ECHONET Lite and has been providing testing and certification services based on ECHONET Lite Standards.
TELEC may accept self-testing results submitted by applicants for certification generally. However, just in case of SMA (Smart Meter Application) Certification, the test must be conducted by the authorized Testing Body according to the regulation of ECHONET CONSORTIUM, and TELEC will provide the test for it.
Testing and Certification of ECHONET Lite AIF
ECHONET Lite AIF (Application Communication Interface) is the interface specification standardized by ECHONET CONSORTIUM for HEMS (Home Energy Management System) controller and other PRINCIPAL APPARATUSES which works together as HAN (Home Area Networks) on the bases of ECHONET Lite Standards.
TELEC has been authorized by the ECHONET CONSORTIUM as Testing Body and Certification Body for ECHONET Lite AIF and has been providing testing and certification services based on ECHONET Lite AIF Specification.
PRINCIPAL APPARATUSES of ECHONET Lite AIF are as follows;
- Low-Voltage Smart Electric Energy Meters
- High-Voltage Smart Electric Energy Meters
- Home Air Conditioners
- Lightings
- Fuel Cells
- Instantaneous Water Heaters
- Household Solar Power Generations
- Heat Pump Water Heaters
- Storage Batteries
- Electric Vehicle Chargers/Dischargers
