Zig

bee v/s Bluetooth Technologies

1. Origin: Bluetooth was launched in the year 1994 by German telecom giant Ericsson

while Zigbee was devised in the year 1998. The name Bluetooth has been derived rom

!o!ular Euro!ean uniication "ing# $arald Blatand while Zigbee gets its name rom the

dance movements o a honeybee.

%. IEEE Standards: Bluetooth# though not under &EEE now# was deined under

8'%.1(.1 standard while Zigbee is deined under &EEE 8'%.1(.4 standard.

). Management Alliances: Zigbee is managed by Zigbee *lliance which tests and

certiies Zigbee based devices. *ll Zigbee based !rotocols get standardi+ed under

&EEE. ,n the other hands# Bluetooth is managed or standards and device by a single

body: Bluetooth -&G -!ecial &nterest Grou!/.



4. Protocol Updates: Bluetooth has been u!dated under version %.'# %.1# ).'# 4.' etc

while Zigbee received u!dates in %''4# %''0 and %''. 2ow Zigbee e3ists in two ty!es:

Zigbee and Zigbee ro which are dierent in terms o addressing algorithms.

(. Frequency: Bluetooth wor"s under %.4 G$+ while 5i67i wor"s at 808 $+# 91( $+

and %.4 $+ reuencies.

0. Channel Bandwidth: Bluetooth based channel consume bandwidths u!to 1$+

while Zigbee based networ"s consume bandwidths o '.)$+# '.0 $+ and % $+

de!ending u!on the reuency at which networ"s are communicating.

. ype o! Computer "etwor#: Zigbee has been designed to communicate under

ersonal *rea 2etwor" whereas Bluetooth based communication serves or 5ide *2

5*2/.

8. Ma$imum num%er o! cell nodes& &n Bluetooth# u!to 8 cell nodes can be connected

to each other while in Zigbee more than 0(#''' cell nodes can be connected together.

9. 'ange: Bluetooth based networ"s can e3ist u!to 1'm# while 5i67i based networ"s

can e3ist rom 1'61''meters.

1'. Sel! (ealing "etwor#s: -el $ealing networ"s are those where networ"ing is not

disturbed i one node gets damaged. &n sel healing networ"s# the nodes neighboring



the damaged node will create a reverting loo!# thus !reventing any inormation to be

sent to the damagednon wor"ing node. This "ee!s the networ" u! and ma"es it more

stable.

Zigbee based systems are inherently "nown to "ee! u! with sel6healing networ"

technology while Bluetooth doesn;t have this technology deined in it# though

ada!tations and research are being made or this.

11. "etwor# opologies: Bluetooth networ" can be established in a !oint to !oint

master6slave method# master and u!to slave !iconet networ"s and scatter net lin"ing

two or more !iconets/.

,n the other hand# Zigbee devices can be networ"ed in star# mesh and other generic

to!ologies. <arious Zigbee based networ" to!ologies can be connected to each other

in orm o a cluster. *ny Zigbee networ" would have three ty!es o nodes: Zigbee

=oordinator# Zigbee >outer andZigbee End!oint.

1%. )atarans!er 'ates: Bluetooth based networ"s have ma3imum data transer rates

o u!to 1b!s while in Zigbee# data transer rates are u!to %('?b!s.

1). Spread Spectrum echniques: -!read -!ectrum techniues count or the

!rocesses through which a signal is s!read over reuency domain.This is done so as

to accommodate more signals# increase signal security# reduce signal intererence etc.



*lmost all wireless networ" !rotocols have deined some ty!e o s!read s!ectrum

techniue.

Bluetooth wor"s on 7reuency $o!!ing -!read -!ectrum techniue while Zigbee uses

@irect -!read -!ectrum techniue. &n 7reuency ho!!ing# the carrier signal is made to

vary in terms o reuencies while in direct s!read s!ectrumA the original signal is mi3ed

and e3tracted rom a !seudo random code at transmitter and receiver# res!ectively.

14. Energy Consumption: 7or any networ"# !ower consum!tion de!ends on the ty!e

o data being e3changed# distance between transmitter and receiver# desired !ower to

be retained by signal and other actors.

Bluetooth is a !rotocol "nown or e3changing almost all ty!es o data such as te3t#

multimedia. ,n the contrast# Zigbee !rotocol is !recisely or o!erational instructions and

not much variety o data is "nown to be e3changed using it.

,bviously# Zigbee consumes signiicantly less !ower than its Bluetooth counter!art.

sually# Zigbee devices are %.(6) times more eicient than those wor"ing at Bluetooth.

1(. Applications: Zigbee based systems are designed or wireless networ"ing among

sensors and is more !reerred or devices which are smaller in si+e and consume less

energy. T< remote controls# -=*@* system sensor# medical instruments etc. are some

areas where Zigbee based networ"ing are done.



Bluetooth based a!!lications are !rimarily in com!uter !eri!herals such as wireless

"eyboards# mouse# headsets etc. *lso# some wireless remotes or gesture controlled

gadgets use Bluetooth to e3change data.
