GPS Jacket Phone
This is a PHS terminal (jacket phone) equipped with GPS. It uses a W-SIM (Willcom-SIM.)
It can perform location searches making use of the characteristics of both GPS and PHS. Out in the open, GPS can precisely identify your location. Inside or underground, PHS can roughly determine where you are.
It has all the basic necessary functions, so you can let your children use it without any worry.
This is a tool that uses cellular phone networks and GPS to send messages from the terminal and identify the location.
The terminal uses cellular phone public networks to send messages.
The messaged location of the terminal can be somewhat determined from the location of the base station the terminal has acquired, or the location measured by GPS.
This is a system that uses PHS and low-power wireless to get messages from the handset.
The moving handset communicates through low-power wireless with the base whenever it can connect. The base delivers the information from the moving handset via the PHS public network. If it cannot communicate with the base, the moving handset uses the PHS public network itself to send messages.
A non-moving handset communicates with the registered base through low-power wireless, and messages from a non-moving terminal are always delivered via the PHS public network from the registered base.
The position of the messaging handset can be somewhat determined from the location of the base, which received a message from the handset, or the position of the PHS public base that the moving handset is connected to.
