#Wifi vs bluetooth vs xbee vs 3g Bluetooth#

While there is more than sixty five thousand (65000) cell nodes in zigbee.īluetooth networks can be built using the point-to-point master-slave approach in which there is one master and up to seven slaves form a piconet, which leads to forming a scatter net which is a linking of two or more piconets. There is maximum of 8 cell nodes in Bluetooth. Whereas it also uses BPSK and QPSK modulation techniques like UWB. There are seventy nine RF channels in Bluetooth. While the frequency range supported in Zigbee mostly 2.4 GHz worldwide.

#Wifi vs bluetooth vs xbee vs 3g Bluetooth#

The frequency range supported in Bluetooth vary from 2.4 GHz to 2.483 GHz. IEEE standardizes all Zigbee-based protocols. The Zigbee Alliance is responsible for managing Zigbee and testing and approving Zigbee-based devices. The Bluetooth SIG (Special Interest Group) is the organization responsible for managing Bluetooth standards and devices. Besides these similarities, there are some differences which are given below in the tabular form. each run within the pair of.4-GHz unlicensed band, and each use tiny kind factors and low power. In the above figure, we can see that the data transfer rate is faster in Bluetooth than in Zigbee whereas Zigbee covers larger distance than Bluetooth.īoth Bluetooth and Zigbee have a lot in common which is, each area unit styles of IEEE 802.15 WPANs. It covers more distance as compared with Bluetooth. the frequency range supported in Zigbee is mostly 2.4 GHz worldwide, which means 2.4 GHz is not supported at all times. Whereas in Zigbee, BPSK and QPSK modulation techniques are used like UWB (Ultra-Wide Band).
