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.
| Specifications | Bluetooth | Zigbee |
|---|---|---|
| IEEE Standard | 802.15.1 | 802.15.4 |
| 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 |
| Frequency Hopping | Yes | No |
| 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. |
