Whether you call it Internet of Things (IThings) or machine-to-machine communications, or their English shorthand IoT and M2M, this use of the relatively mainstream IP position and wireless communication technology, It will change the world forever.

Making many—or even most—objects embedded in the “cloud” function will change the nature of these objects and their derivatives; and the dialogue between these machines and machines will be carried out in secret, doping such as mobile phone tapping events A general, disturbing echo. Some people may think that "humans are good, machines are not good"; or it is more practical to think that "some humans are not good, but machines are neutral"; but in any case these are simplified ideas, and before conclusions are made Remember, technologies such as M2M have the potential to bring unlimited benefits to the world as long as they can be properly controlled and utilized.

Freescale Semiconductor recently held a seminar in Scotland, UK, inviting industry leaders from Oracle, IBM, Google and other industries to explore how to create useful, reliable, and secure M2M. /IoT application. For example, Freescale pointed out that as many as 1.2 million people accidentally die in traffic accidents worldwide every year, but if you can use the communication technology between vehicles and vehicles, you can start the vehicle braking system faster before the driver reacts. Or make better use of ABS to prevent collisions from happening.

Such considerations and other potential applications lead to a necessary conclusion: If the M2M revolution really happens, it will definitely be based on wireless networks and security.

In addition to saying that the M2M technology in the car will be realized, Freescale’s people also told me that the lines in some high-end car models on the market currently total 6 kilometers (kilometers), which means that the subsystems in the car will be heading in the future. "Wireless" development can reduce weight and save energy. However, the wireless communication between vehicles and vehicles and inside the vehicle, together with various legal/unlawful interventions, and malicious software, will still pose challenges related to safety and reliability.

In addition, IoT applications will have to be considered. Many of them may only use existing wireless infrastructure, such as Wi-Fi, 3G and LTE, but their IP locations are inherently limited, and more and more are dedicated to IoT channels. Demand may seriously crowd out communication between people. So then we may have to ask, in the end what applications are so economically attractive that they can justify the need for a dedicated wireless infrastructure?

There is already a plan to use M2M, called “Electric Sheep”; this is a collective art of abstraction and software installed in thousands of ordinary PCs. When those computers that have installed software enter hibernation, the “e-sheep” programs will communicate with each other to create abstract animations. In addition to security issues, I think another problem with IoT/M2M technology lies in human trust and feelings. . When a vehicle can spontaneously activate a braking system because it knows that it is "better than not doing it better," what would humans feel? If people are thinking about changing their tastes, but what is the feeling in the fridge that has been ordered automatically by the refrigerator in accordance with a repetitive rule? Or when the smart grid automatically shuts down/turns on the appliances in the home just because it thinks that it's time to sleep, how would we feel?

You may or may not like it, but the machine will not care about it.
