Bluetooth
and IEEE 802.11b Although aimed at different markets and roles,
there has long been speculation about the effects 802.11b and
Bluetooth have on each other, not just technical interference, but
also whether they are in competition with each other commercially.
Often these are simplistic press reports attempting to compare the
two and seeking to decide a winner. This article however explains
the similarities and differences between Bluetooth & 802.11b on
a broad level and tries to show that there is no serious competition
between the two.

Minimizing
Bluetooth Interference (7/02) Bluetooth provides relatively low
data rates for supporting short-range, wireless personal area
network (PAN) applications. Bluetooth radios are starting to appear
more often now in laptops, headphones, cell phones, and PDAs, which
results in much less cabling for users to deal with. The deployment
of both Bluetooth and 802.11 networks in the same area is a bit
risky, though, because of the potential for interference. Similar to
802.11b, Bluetooth devices operate within the 2.4 GHz band. The
difference is that that Bluetooth uses frequency hopping (at 1,600
hops per second) to hop over the entire 2.4 GHz band. 802.11b, on
the other hand, uses direct sequence and only occupies approximately
one third of the 2.4 GHz band. As a result, Bluetooth hops all over
802.11b transmissions. |

A
comparison of Bluetooth and 802.11 (PDF, 2MB) This document
provides a comparison of Bluetooth and 802.11. It provides
information on forecasted markets, an 802.11 technical overview, OSI
models, modes, features, international band plans, usage scenarios
and interoperability. |

Conflicts
between Bluetooth and wireless LANs called minor (2/01) Wireless
Bluetooth links and 802.11b wireless LANs can clash, but the
conflicts are within acceptable limits, according to tests from two
systems makers. However, clouds still hang over the expected rollout
of Bluetooth products later this year and some notebook makers said
they will not build Bluetooth into their portables until 2002. |

Bridging
Bluetooth and 802.11b (10/01) Many people seem to have the
misconception that Bluetooth and 802.11b are competing standards -
but in reality, they compliment each other. Wireless network access
through the 802.11b standard, delivering a maximum transfer speed of
10 Mbps, has grown to become immensely popular both in workplaces,
homes and as access points in hotels, cafes and other public
hotspots like airports. However, Bluetooth, which only has a range
of approximately 10 meters compared with 802.11b's approximately 300
meters (both best case scenarios), hasn't been greated equally
welcome when it comes to establishing semi-permanent wireless
connections to networks of various kinds.

Bluetooth
can coexist with 802.11 (2/01) Wireless solutions will not only
need to provide seamless connectivity but since they will operate in
the unlicensed bands, they will have to be robust to prevent
potential interference. Interference resistance is going to be a
"must have" feature for all radios that operate in
unlicensed bands. But the problem is not the band-it's building the
right solution. |

Reliability
of IEEE 802.11 Hi Rate DSSS WLANs in a High Density Bluetooth
Environment (PDF) The issue of coexistence between IEEE 802.11
high speed Direct Sequence Spread Spectrum (DSSS) and Bluetooth
radios with both radio types located within a mixed environment is
studied. A network topology, propagation model, and user traffic
loads are postulated. The reliability of IEEE 802.11 Hi Rate DSSS
radios is then estimated under the stated conditions. |

Bluetooth
vs. WiFi: Why it's NOT a death match (5/02) Does the world
really need two wireless networking technologies? Bluetooth and WiFi
(aka 802.11b) have both been much in the news lately. Of the two,
WiFi got the fastest start. But Bluetooth is gaining traction in the
marketplace; Microsoft, for example, has announced that it will
build native Bluetooth support into a future version of Windows
