Overview
Bluetooth
Bluetooth wireless technology is one
of the most prominent short-range
communications technologies with
an installed base of more than three
billion units. Bluetooth is intended
to replace the cables connecting
portable and/or fixed devices while
maintaining high levels of security, low
power and low cost. A fundamental
strength of Bluetooth is the ability to
simultaneously handle data and voice
transmissions. Bluetooth is designed
to have very low power consumption
by allowing radios to be powered
down when inactive. The Bluetooth
specification defines a uniform
structure with global acceptance
to ensure interoperability of any
Bluetooth-enabled device.

How does Bluetooth technology
work?
Bluetooth technology operates in the
unlicensed industrial, scientific and
medical (ISM) band at 2.4 to 2.485
GHz, which is available and unlicensed
in most countries. Bluetooth uses a
spread spectrum, frequency hopping,
full-duplex signal which was designed
to reduce interference between
wireless technologies sharing the
2.4-GHz spectrum. Bluetooth tech-
nology provides greater performance
even when other technologies are
being used along with Bluetooth
technology. Information above cited

Why TI Bluetooth?
TI is one of the leading semiconductor
companies providing Bluetooth
wireless technology for portable,
battery-powered devices leveraging
nearly a decade of experience and
seven generations of products
which are optimized for the needs
of handheld products. TI is also the
market leader in combined wireless
products such as the WiLink™ 8
solution single-chip Wi-Fi
®
/Bluetooth/
Bluetooth low energy device), CC2560
(Bluetooth), CC2564 (Bluetooth/
Bluetooth low energy), which further
solve issues such as coexistence,
antenna sharing in size-constrained
devices, cost and power consumption.
Dual mode
Dual-mode Bluetooth low energy
technology is available as a part of
TI’s proven WiLink connectivity combo
solutions. These solutions support
Wi-Fi and dual-mode operations by
providing classic Bluetooth technology
capability along with Bluetooth low
energy technology. The WiLink 8
module solution includes on-chip
coexistence, which yields size, cost,
performance and power advantages
that ease customer development
cycles. WiLink brings connectivity
features to mainstream products such
as smart phones, mobile Internet
devices (MIDs), portable media players
(PMPs), gaming devices and personal
navigation devices (PNDs).
For longer range, higher throughput
and ability to connect to any mobile
phone or tablet on the market, TI also
has a Bluetooth dual-mode solution,
the CC2564. It is used for audio
and data applications and supports
Bluetooth and Bluetooth low energy,
assisted audio (SBC encode/decode)
or ANT™ running simultaneously.
