B L U E T O O T H ® TECHNOLOGY
What is Bluetooth® Wireless Technology?*
Bluetooth is a wireless communication system standard that
allows connectivity and collaboration between disparate products
and industries. It allows the headset to work with mobile phones,
leak detector equipment and a wide variety of other Bluetooth
compatible devices.
How does Bluetooth technology differ from other radio technologies?
Mobile phones, FM radio and television all use radio waves to send
information wirelessly. And while Bluetooth technology also uses radio
waves, it transmits them over a shorter distance. Bluetooth technology sends
information within your Personal Area Network or “PAN” (aka your own
personal space) at distances up to 100 meters (328 feet) depending upon
device implementation. Bluetooth technology operates in the unlicensed
industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a
spread spectrum, frequency hopping, full-duplex signal at a nominal rate of
1600 hops/sec.
Is Bluetooth technology hardware or software?
It’s a combination of both. Bluetooth includes a small computer chip
containing the Bluetooth radio. But it also needs software to connect, via
Bluetooth wireless technology, to other products. This is accomplished
through adaptive frequency hopping (AFH) capability. AFH was designed
to reduce interference between wireless technologies sharing the 2.4 GHz
spectrum. AFH works within the spectrum to take advantage of the
available frequency. This is done by the technology detecting other devices
in the spectrum and avoiding the frequencies they are using. This adaptive
hopping among 79 frequencies at 1 MHz intervals gives a high degree of
interference immunity and also allows for more efficient transmission within
the spectrum. For users of Bluetooth technology this hopping provides
greater performance even when other technologies are being used along
with Bluetooth technology.
