9. Nokia 30 as an M2M Communications device
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
■ User control 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.
