What is the Difference between Zigbee, Infrared, Wireless, Bluetooth and Wi-Fi
With the passage of time, we are going through more and more technological advancements. Now a day communication and data transfer between different devices become necessary and requires a faster speed. Wireless data transfer mechanisms are getting common and advancing day by day. Infrared, Bluetooth, zigbee and Wi-Fi are the different type of mechanisms used for wireless data transfer and multimedia communication. Let’s have an overview between the differences of them.
Wireless
It is a way of telecommunication between two or more devices without any physical connection. We can communicate or transfer data from any distance according to our device range. The distance can be some meters or thousands or million kilometers with radio transmission. Wireless computer mice and head sets are the simplest example of wireless communication.
Infrared
It is a short range wireless communication tool. Infrared rays are the electromagnetic radiations which contains a wave length longer than visible light. These are the radiations which emitted from an object at room temperature. Their frequency range is from 1 to 400 THz. Infrared rays are used for industrial, medical and scientific purpose.
Zigbee
It is another wireless communication tool. Zigbee is suitable for high level communication protocols which used low power digital radio base. It is used in different applications like electrical meters, wireless light switches etc. Zigbee is low-rate wireless data transfer in which data is transferred within short distance like Bluetooth.
Bluetooth
It was the alternate of data cables used for transferring of data between mobiles and PC. Bluetooth is a wireless technology for transferring of data in short distances. It uses short wavelength radio transmission of 2400 to 2480 MHz. It was also beneficial as compare to synchronization and limitation of connecting more than one device at a time.
Wi-Fi
It is the latest wireless technology now a day. It is used for long distance wireless communication. Between different electronics devices like computers, mobiles etc. devices are wirelessly connected with internet access points. The access point or hotspot range is 20 meters indoor and it may be in many square miles by overlapping of multiple access points.
Infrared vs Bluetooth vs Zigbee vs Wi-Fi vs Wireless
The difference between above mention wireless technologies is actually the advancement in technology by passage of time. Earlier when infrared devices used, there was a limitation of wireless data transfer between different devices and it is used to connect just two devices. With Bluetooth we can connect with many devices and it is safer and fast then infrared. Another difference between infrared and Bluetooth is distance enhancement. Zigbee technology is also for short range data transfer but the difference between zigbee and Bluetooth is that zigbee is low-rate and inexpensive wireless technology. It is also suitable for high level application. The difference between Wi-Fi and other wireless technologies is, it connects with internet access point or hotspot. It is most fast wireless technology as compare to infrared, Bluetooth or Zigbee. The major difference of Wi-Fi is that, we can increase the distance by overlapping multiple access points whish makes it more efficient and fast than old wireless technologies.
