What are IoT technologies?

a. NFC and RFID: Both NFC and RFID are responsible for providing simple, low energy and versatile options for identity and access tokens, connection bootstrapping and payments.

RFID employs 2-way radio transmitters receivers for identifying and tracking tags that are associated with the objects.
NFC consists of communication protocols for electronic devices usually mobile and a standard device.

b. Low Energy Bluetooth: This supports low power, long-used need of IoT functions while exploiting a standard technology along with native support across the systems.

c. Low Energy Wireless: The sensors and other elements can power down the long periods, communication links and need to remain in the listening mode. The low-energy helps in reducing consumption along with extending the life of the devices.

d. Radio Protocols: Protocols such as ZigBee are used for creating low-rate private area networks. They are low power but offer high throughput. This results in an increased power of small local device networks without including the typical costs.

e. LTE-A: LTE-A or LTE Advanced is used for delivering increased coverage along with reduced latency and a raised throughput

f. WifFi-Direct: It eliminates the need for an access point. It allows P2P connections at a WiFi speed with lower latency. WiFi-Direct eliminates an element of the network that lowers it and doesn’t compromise on the throughput speed.
