BusinessWi-SUN Testing Service

We provide the necessary testing services for obtaining Wi-SUN certification, issued by Wi-SUN Alliance, relating to Wi-SUN (Wireless Smart Utility Network) radio equipment, which is expected to be the next big development as a means of M2M communication, such as smart meter application (SMA).

About Wi-SUN

Telecommunications equipment that utilizes radio waves, as exemplified by cellular phones, has gained familiarity in our daily lives. However, recently radio equipment is also installed in vending machines and various sensors, and M2M communication, where machines automatically exchange information between themselves, has also become common. In this environment, the introduction of smart meters installed with small-scale and long-life radio equipment in electricity meters, gas meters and various meters is ongoing. These high-function smart meters are networked with what is known as a smart utility network (SUN) or Wi-SUN. As shown in the diagram below Wi-SUN is aligned in coordination with a wide area network (WAN) to make utility operations more efficient.


Wi-SUN is a communication standard based on global standards of IEEE802.15.4g/4e. Currently, the international industrial organization Wi-SUN Alliance is focusing on devices that utilize a 920MHz band and pursuing their standardization and related promotion activities with concrete application in mind.

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.
As shown in the table below, each test is divided further, thus five test items are conducted in total. (As of December, 2014)


Conformance Test PHY Conformance Test
MAC Conformance Test
ENET Conformance Test
Interoperability Test PHY Interoperability Test
ENET Interoperability Test

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
- Electric Vehicle Chargers/Dischargers, Electric Vehicle Chargers
- Commercial-use package air conditioner

- Lighting system
- Expansion Lighting system
- HEMS controllers

Inquires information

TELEC will provide applicants assistance for their application and also preliminary testing service prior to actual testing or certification procedures to get for Wi-SUN Alliance Certification, ECHONET Lite Certification or ECHONET Lite AIF Certification. Applicants may apply “Technical Regulations Conformity Certification” regulated by the Radio Act and “Technical Standards Conformity Approval” regulated by the Telecommunications Business Act, which are occasionally essential to permeate the telecommunication equipment in the Japanese market, to TELEC in conjunction with the application for Wi-SUN Alliance Certification/Testing, ECHONET Lite Certification/Testing or ECHONET Lite AIF Certification/Testing.
