About Us

As Internet of Things (IoT) becomes increasingly popular, more and more devices, including open (SIM free) devices that uses cellular module, are expected to be connected to a carrier’s network.

To help promote such devices to a wider audience. To enable an ever easier connection to our network.

Bearing in mind the goals above, we provide all the necessary information to conduct our connectivity verification (IOT: Interoperability Testing) on this site.

IOT Goals

Overview

Overview
  1. ①:Products that have passed IOT (IOT-verified products) are listed here
  2. ②:Products offered by KDDI are listed 「here」 (in japanese only)
  3. ③:Customers who wish to use IOT-verified modules are advised to read the Guideline for Embedding Communication Module~KDDI LTE Network Specification Outline and Legal Compliance~ available in our Member's Page

Connectivity Verification (IOT : Inter-Operability Testing)

A protocol test to confirm the interoperability between manufacturer-branded products and the KDDI Network.
For IOT, there are two separate connectivity verification services available: "KDDI Network IOT" for testing connectivity with KDDI base stations and "au Starlink Direct IOT" for testing connectivity with Starlink satellites.

IOT Type

1 KDDI Network IOT Verification of connectivity with KDDI base stations (LTE/5G/LPWA).
2 au Starlink Direct IOT Verification of connectivity with Starlink satellites.
The test subjects are Android-based devices that support Satellite Mode.

Test Outline

1 Pre-IOT Tests conducted using simulator
2 IOT-L (Lab Test) Test(s) conducted in KDDI's lab (※1)
3 IOT-F (Field Test)(※2) Test(s) conducted in KDDI's commercial network. (Parts of the test are conducted using simulator)
  1. ※1: KDDI's lab is located in Tama, Tokyo.
  2. ※2: Technical Regulations Conformity Certification or Attestation of the Construction Design of Specified Radio Equipment is required to conduct field test.

Network Architecture

KDDI's connectivity verification is for both LTE and 5G systems.AS such, the information provided on this site also relates to LTE and 5G systems.
