Description

AN APPARATUS FOR MACHINE-TO-MACHINE COMMUNICATION

Technical Field The present invention relates to an apparatus which enables to realize communication between interrelated embedded systems.

Background of the Invention Machine-to -machine (M2M) communication is a name given to technologies which enable wired or wireless systems to communicate with other devices having similar features.

Today, there is a modem in order to provide communication and a programmable microcomputer system in order to carry out functions in M2M embedded systems. In the most frequently encountered use, hardware is designed such that it will realize expected functions by taking into consideration hardware design requirements of components such as the said modem, central processor, memories, etc. Production of printed circuits, arrangement of circuit components, component and system tests are carried out so as to produce this specialized hardware and this process is repeated for every new M2M embedded system model and version. The design and production cycle required by this method leads to high costs particularly for low volume productions. As an alternative method, today there are integrated modules of modem and processor on which there is a limited processor and again has a limited programmability capability. Even though the hardware design and production necessary for using these modules are less than the model described in the previous paragraph, they are still in significant proportions. Due to the fact that SIM (Subscriber Identity Module) card cannot be provided on module in solutions using GSM (Global System for Mobile Communications) network, it is necessary to be added in design additionally. Costs of integrated modules may be higher in contrast with the cost advantage provided in design and production by means of this method. On the other hand, limited capability of processor and programmability creates another disadvantage.

The United States patent document no. US20070191007, another application in the state of the art, discloses a method and system which enables to realize highspeed wireless communication. Summary of the Invention
