Bluetooth vs Zigbee-difference between Bluetooth and zigbee
This page covers comparison between bluetooth and zigbee wireless PAN technologies. It covers difference between bluetooth and zigbee technologies.
|RF Frequency Band||ISM bands country wise as mentioned below: USA and Europe-2400 to 2483.5MHz , Japan-2471 to 2479MHz, France-2445 to 2475MHz, Spain-2446.5 to 2483.5MHz||868MHz in Europe 915 MHz in Australia/USA, 2450 MHz worldwide|
|Channel Spacing||1 MHz||5 MHz, Occupied bandwidth is about 2 MHz.|
|No. of Channels||USA & Europe- 79, Japan, France and Spain-23||16 channels for 2450 MHz band, 10 channels for 915 MHz band, 1 channel for 868 MHz.|
|Distance||10 cm to 100 meters based on Bluetooth device power class||10 to 100 meters based on transmit power, antenna etc.|
|Data rate||Devices as per Bluetooth 1.0 Specifications offer about 1 Mbps, Devices as per Bluetooth 2.0 offer up to about 3 Mbps.||868/915 band provides about 20/40Kb/s respectively. 2450MHz band provides about 250 kb/s data rates|
|Modulation||GFSK (Gaussian Frequency Shift Keying)||BPSK(Binary Phase Shift Keying) for 868/915 MHz and OQPSK(Orthogonal QPSK) for 2450 MHz, Uses DSSS to convert bits/symbols to chips.|
|Protocol Stack||Core protocols- (Physical layer called baseband layer, Link Manager Protocol, Logical Link Control and adaptation protocol, Service Discovery Protocol),cable replacement protocol layer(RFCOMM) Telephony Control Specification Binary Existing protocols- PPP, TCP,UDP,IP,OBEX,WAE/WAP||Physical layer, MAC layer, network, security and application|
|Security||128 bit AES||128 bit AES|
|Topology||Bluetooth device can communicate with about 7 devices in one piconet region.||Star, tree, mesh topologies are supported. Zigbee works as per master-slave configurations. Max. Number of network nodes is 65536.|
|Medium Access scheme||FH-TDD-TDMA||CSMA/CA|
|Applications||It is alternative technology to replace cable for data communication. Used for Home automation, consumer electronics, smart energy, automotive.||It is mainly used for monitoring and control applications. Used for Home automation, consumer electronics, smart energy, automotive.|
