Domestic IoT Solutions
Wide coverage area
LTE, CDMA 1X WIN, CDMA 1X are available in a wide coverage with a stabilize signal.
|CDMA 1X WIN||144kbps||2.4Mbps|
- In some areas, the maximum receiving speed is 37.5Mbps and the maximum sending speed is 12.5Mbps.
- Since this service is provided as a best-effort service, communication speed is subject to the influences of the communication environment and traffic conditions. Even within the service area, data communication may not be available in locations with weak signals.
- Service area and speed vary depending on the model of your communication module and your rate plan,
KDDI Module Remote Management Service (KDDI MRMS)
This service allows users to monitor and operate communication module devices remotely via the Internet.
You can check the installation site (GPS information) of a product equipped with a communication module device as well as the signal condition in the surrounding area, and confirm and change the setting of communication module devices.
|Remote monitoring function||Allows users to check the received signal condition of communication module devices via a network.|
|Remote operation function||Allows users to check and change the detailed setting of communication modules via a network.|
|Monthly basic charge||¥10,000/ID|
|SMS distribution charge
(number of distributed SMS mails)
|50,001 and over||¥20,000 is added every 50,000 mails|

|Usage fee/Information charge||Free|
Due to the adoption of the gpsOne system, which uses the GPS satellite positioning information in combination with the au base station location information, approximate location can be positioned even in places like underground or indoor locations where satellite signals cannot reach, as long as the device is in the au service area. In addition, shorter time is needed for positioning compared to the conventional system of positioning only using the GPS signal.
- Location positioning is possible without a GPS unit.
Protocol conversion function
Data transmitted from a device with embedded communication module is automatically converted to TCP/UDP protocol to be sent out as packets. This saves customer products from having a TCP/UDP stack, enabling product development with reduced cost.

OTA (Over The Air) function
Lines can be opened or stopped by writing or deleting the ID information of a phone number via wireless operation.
This function can prevent communication charges from being incurred during the manufacturing process of a product or while a product is in stock.
Date & Time / Easy location information acquisition function
The accurate time information and the approximate location information based on base station can be acquired with AT commands. This enables the omission of a time server and allows users to know the location the device is used at.
- All of the indicated amounts exclude tax unless otherwise specified.
