Bluetooth
1.2 & Bluetooth 2.0 The recent release of cores based
on preliminary Bluetooth 1.2 and speculation on the abilities
of Bluetooth 2.0 means that far-sighted developers should not
stand still in approaching Bluetooth optimisations. This
article explains the features on a broad level of Bluetooth
1.2 and examines the reports on Bluetooth 2.0. Read

Bluetooth
Additional Profiles - Overview
The Bluetooth SIG has released 12 new profiles. In conjunction
with this, palowireless has also published on-line new
tutorials to these profiles. However, with the
proliferation of profiles and acronyms it is sometimes hard to
see what these profiles are designed to do. As an entry-level
introduction, this article gives a very brief outline of these
new profiles and what roles they will allow Bluetooth units to
fill. Read

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

the two. In fact both have their own advantages and
disadvantages, and both technologies can complement each
other... Read

Bluetooth Mobility
& Roaming Two major current limitations of
Bluetooth are: that communication between devices must be
direct; and secondly that they do not support the movement of
an active terminal from one network interface device to
another. Essentially in Bluetooth, a device in a piconet A
cannot communicate with another bluetooth device in a
different piconet B, regardless if it was a member of piconet
A previously. This article briefly examines several
theoretical ways in which these interpiconet issues could be
handled and developed... Read

Bluetooth Security
- Part 1 Nothing has caused more concern and confusion in
Bluetooth than the nature of Bluetooth security
implementation. From those who insist that its security is a
disaster area, prey to any half-capable opportunist, to the
contrary view that’s its security is second to none...

Bluetooth Security
- Part 2 Last month we examined the lower level of
Bluetooth security (Link Level security). This month we look
at the Security Mode 2 ( the service level enforced security )
and a possible implementation of it. We also evaluate the
overall merits/drawbacks of Bluetooth in the security
arena.... more... |

- Part 3 As shown in parts 1 & 2 of this article,
Bluetooth has a comprehensive set of security features, at
both upper and lower levels. However for all of it's security
features, Bluetooth does have some security
