GPS function

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.

Supported modules

KYM11, WM-M300, WM-M320, WM-M200A, WM-M210A, KCMV-200

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.
