Internet of Things (IoT) Technology and Protocols - Internet of things (IoT)

What are the different protocols and technology used by IoT?

The standard protocols and networking technologies are exploited by IoT. Some of the technologies and protocols of IoT are RFID, NFC, low-energy Bluetooth, low-energy wireless, low-energy radio protocols, LTE-A, and WiFi-Direct. The networking functionality required by IoT system is supported by these technologies against the standard uniform network.


A simple low energy and versatile option for identity and access tokens, bootstrapping connection and payments are facilitated by RFID (radio-frequency identification) and NFC (near-field communication).

  • A 2-way radio transmitter receiver is employed by the RFID technology for identifying and tracking the object associated tags.
  • The communication protocols for electronic devices such as a mobile device or a standard device is provided by NFC.

Low-Energy Bluetooth

The low-power, long use need of the IoT function is supported by this technology during exploiting a standard technology supporting the systems.

Low-Energy Wireless

The hungry aspect of the IoT system, which is most powerful, is replaced by this technology. The communication links should always remain in listening mode in spite the sensors and other elements power down over long periods. Consumption is reduced and the life of the device is extended by less usage through low-energy wireless.

Radio Protocols

Low-rate private area networks are created by radio protocols such as ZigBee, Z-Wave, and Thread. Even though the technologies are low-power, they offer high throughput thus enabling to increase the small local device network power without additional costs.


An important upgrade to LTE technology is LTE – A or LTE Advanced, which increases the coverage, raise the throughput and reduce the latency. By expanding its range, LTE – A provides huge amount of power for IoT by using the most significant applications like vehicle, UAV, and similar communication.


The requirement for an access point is eliminated by WiFi-Direct. P2P connection is facilitated with WiFi speed at lower latency. The element of the network which bogs the network down is eliminated by WiFi Direct without compromising on speed or throughput.
