Overview
Wi-Fi IEEE 802.11 a/b/g/n
Wi-Fi continues to effectively penetrate
the wireless market with an installed
base of over 3.5B units with an annual
shipment rate exceeding a billion units.
Nine out of 10 Americans surveyed in
a consumer poll said they would rather
do without Starbucks for a year than
give up their Wi-Fi connection! It is
easy to see how the Internet of Things
(IoT) is expected to grow to 50 billion
connected devices by 2020.

How does Wi-Fi technology work?
Wi-Fi networks use radio technologies
based on the IEEE 802.11a, 802.11b,
802.11g and 802.11n to provide
secure, reliable, fast wireless
connectivity. Wi-Fi networks operate
in the unlicensed 2.4- and/or 5-GHz
radio bands at rates of 54 Mbps or
greater. They can provide real-world
performance similar to the basic
10BaseT wired Ethernet networks. For

Why TI Wi-Fi?
Texas Instruments is the world’s
leading supplier of Wi-Fi products for
portable, battery-powered products
leveraging nearly a decade of
experience and eight generations of
products which are optimized for the
needs of personal technology and
handheld products for the IoT. TI is
also the market leader in combined
wireless products such as the pre-
certified, preWiLink™ 8 module (single-
chip Wi-Fi/Bluetooth
®
/Bluetooth low
energy device) which further solve
issues such as coexistence, antenna
sharing in size-constrained devices,
cost and power consumption.
TI enables simple Wi-Fi connectivity
with the self-contained SimpleLink™
CC3000, which allows very short
design cycles by eliminating the need
for extensive RF and Wi-Fi expertise.
