Wireless Communication Protocols for Internet of Things (IoT)

This presentation discusses the various wireless communication protocols used in IoT, including Zigbee, RF Links, NFC, Bluetooth, BLE, Wifi, and more. It explains how these protocols work, their range, data rate, and applications. The presentation also provides references for further reading.

Wireless Communication Protocols
for Internet of Things (IoT)

• It stands for Internet of Things.
• It is one of the revolution technologies of
this decade which will transform the
standard of living of the society.
• In this technology smart devices are
connected with each other so that they
can share information and communicate
without human involvement.
What is IoT

 Communication is achieved through
electromagnetic waves.
 Air is used as channel.
 There is one transmitter and a receiver.
Both uses antenna to change electrical
signals to electromagnetic waves and vice
versa.
Wireless Communication

 It follows IEEE 802.15.4 standard.
 Range is 10-100 metres.
 Data rate is 250 kilobits per second.
 Zigbee has low data rate, hence it is mostly
used in home automation, collecting data
for medical devices, smart energy devices
and other application which require low
power and low bandwidth
Zigbee

 It uses radio frequencies for identification
(RFID).
 Two main components are tag and reader.
 Range depends on the transmission power.
 Near field Communication (NFC) also uses
radio frequencies.
 NFC is used in range of 4cm.
 Used in smartphone payment systems.
RF Links and NFC

 It follows IEEE 802.15.1
 Developed by Jaap Haarsten in 1994
working for Ericson.
 Typical range is within 10 metres.
 BLE stands for Bluetooth Low Energy.
 Upgraded version of bluetooth with low
energy consumption with same
communication rate.
Bluetooth and BLE

 It follows IEEE 802.11 standard.
 It stands for Wireless Fidelity.
 Most widely used for IoT.
 It uses two frequency bands which are,
2.4GHz UHF and 5.8GHz SHF ISM bands.
 Range depends up on the power of
transmitter and receiver.
 Security is less as compared to wired
networks.
Wifi

 WiMAX: It stands for Worldwide
Interoperability for Microwave Access. It has
a high data speed of 40 megabits per
second which was upgraded to 1 gigabit per
second.
 Z-wave: It was developed by Zensys in
2001. It is widely used in home automation.
Range is up to 100 meters and is uses 800-
900MHz radio frequency range for
communication.
