Nokia 30 GSM 사용자 설명서

M2M stands for machine-to-machine, man-to-machine and machine-to-man communication. M2M 
is a simple way to use wireless data transmission as a link between systems, remote devices or 
locations and individuals.

With the Nokia 30 connected to a machine through a control application, you can remotely control a 
pool of devices and receive status information, for example storage statuses. The Nokia 30 can be 
easily integrated into various applications such as vending, security, elevator control and so on.

As an M2M communications device the Nokia 30 can be used in  three operation modes:

• User control mode

• AT command mode

• M2M system mode

■

A user can control and monitor devices by mobile phone using text messages. An example of 
controlling a device would be to lock a door remotely with a mobile phone.

With the User Control mode of Nokia 30 it is easy and economical to develop e.g. this kind of door 
locking system. This is possible using the built in services of the Nokia 30 and the specific input and 
output pins located on the M2M System Connector, see page 15. For more information on User control 
mode, see the Nokia website www.forum.nokia.com for more specific documentation.
