The Internet of Things has been called for many things, and it can be termed as the “Future of Technology,” it can also be coined as the “Greatest Innovation,” and so many others. However we only know that the Internet of things or referred to as IoT as the interconnected device and for a machine or device to work, one must have software. IoT is the network of physical objects that carry embedded technology to communicate or interact.
The most important thing about the Internet of Things is the connectivity among these devices or objects. However, how can these be adopted and how are these connected devices being able to communicate with each other? It is simple; it is through the use of wireless connectivity. Let’s run down some of the IoT protocols and how can these wireless communication brought about by IoT evolve.
Bluetooth
Bluetooth has become an essential aspect when it comes to communicating and computing many consumer product markets. It is only known as the wireless technology used for exchanging data over short ranges. Bluetooth exists in many products such as tablets, phones, media players and the wearable devices we used. Bluetooth technology is already a widely used and established technology, but if people will switch it off, there might be issues on the usage of this technology.
Wi-Fi (Wireless Fidelity)
For some reasons, it can always be associated with Bluetooth as there are comparisons between these two especially when it comes to their usage and application. Wireless Fidelity provides access to devices that are within the range which is about sixty-six feet from the access point. It can be protected and controlled, but there might also be inconsistency because of the signal.
Radio Frequency
This might be the easiest way of communication. It is with the help of frequencies that make this technology work. Phones, radio, wireless television are using this technology. Although this communication is considered as one of the oldest, however, it is simple, and it has a wide variety of frequencies on which different gadgets or devices can transmit. However, it should be noted however that the radio frequency technology is not used in smartphones.
Satellite
We use satellite communication to connect our smartphones to communicate with each device. They are called in different ways like GPRS, GSM, 3G, 4G, and others. When it comes to the Internet of Things, this form of communication can be preferred as Machine to Machine or “M2M”. This technology works like it will allow the device which is the phone to transmit data through the use of cell network.
Message Queue Telemetry Transport (MQTT)
MQTT is a protocol that is lightweight and sends simple data from sensors to different applications. This IoT protocol functions on TCP/IP (Transmission Control Protocol/Internet Protocol) and is composed of three components namely: subscriber, publisher and the broker. Message Queue Telemetry Transport suits low power devices and those who have low memory.
There are many IoT protocols and to choose which the best is a big question. It will be determined on how you use this technology. However, one thing is for sure, the Internet of Things is still emerging, and with that, there will still be a lot of protocols that can be used.
