to provide secure, reliable, fast wireless connectivity.
Wi-Fi networks operate in the unlicensed
2.4- and/or 5-GHz
Introduction to Wireless
A Better Connected World
That's Smart. That's Bluetooth.
ZigBee is a low-cost, low-power, wireless
standard targeted at wide development of long battery life devices in
Wi-Fi (Wifi / WiFi), is a
local area wireless technology (also
: wireless local area network )
that allows an electronic device to exchange data or connect to the internet.
Bluetooth Low Energy
IEEE 802.11 Families
Medical devices and remote patient monitoring
Consumer devices (tablets, e-books,
media players), web browsing,
Internet connectivity, and streaming
Industrial and home automation,
remote monitoring, controlling, data-logging and diagnostics
Security and surveillance

ZigBee builds on the physical layer and media access control defined in IEEE standard
for low-rate WPANs.
ZigBee operates in the industrial, scientific and medical (
) radio bands:
in most jurisdictions worldwide;
784 MHz in China
868 MHz in Europe
915 MHz in the USA and Australia
. Data rates vary from
(868 MHz band) to
(2.4 GHz band).
The ZigBee network layer natively supports both star and tree networks, and generic Mesh networking.
ZigBee is accounting for almost
shipments in 2018.
