There are several technologies and protocols that are used while designing the IoT based applications, Bluetooth, wifi, radio protocols, LTE-A etc are some major IoT technologies and protocols.
Let's discuss all these protocols in detail.
Bluetooth
Bluetooth is one of the short range IoT protocols. Bluetooth is an essential part of most of the electronic devices that are available in the market.
Low energy bluetooth are technologies that support low power, long use of IoT function.
WiFi
WiFi had eliminated the need of an access point. It allows peer to peer connection with lower latency and with speed of WiFi. WiFi does not compromise with the speed.
LTE - A
LTE-A and LTE Advanced is an upgradation of LTE technology. This advanced LTE technology has reduced the latency and pricing and has increased its coverage.
NFC and RFID
Near field communication ( NFC) and Radio frequency identification (RFID) provides low energy and flexible options for accessing tokens, bootstrapping and payment methods.
Radio Protocols
Radio protocols such as ZigBee, Z-wave are radio protocols that create a low private area network. These are low power technologies but offer high output and increase the power of small local devices.
