Many have predicted that the Internet of Things is “the next big thing” in the world of information technology, it is because the “Internet of Things” offers a lot of potential that can be extracted. A simple example of implementation of the Internet of Things is a refrigerator that can notify the owner via GSM or web about food and drink anything that has run out and should be stocked again.

Internet of Things The initial idea was first raised by Kevin Ashton in 1999 in one of his presentation. Currently, many large companies began to explore the Internet of Things just call Intel, Microsoft, Oracle, Samsung and many others.

Device IOT how to communicate?

An IOT has a radio device that can send and receive wireless connection. IOT wireless protocol designed to meet some basic services: Operates with power and low bandwidth, and work in a mesh network. Some devices work on the 2.4 GHz frequency field, which is also used by Wi-Fi and Bluetooth, and a sub-GHz coverage. The sub-GHz frequencies including 868 and 915 MHz, have an advantage in the low interference.

IOT devices connected in a mesh network with each other and send signals like runners in a relay race. This network is the opposite with a centralized network. Coverage transmission of IOT devices in a mesh network is ± 9 meters to over 90 meters. Because the devices in a mesh network capable of “transfer” signal, of course they can connect with thousands of sensors in a large area, such as a city, and operate in harmony. Mesh networks have the additional ability to work around the area of ​​the device that failed (not connected).
