Technology, Applications and Compatibility (Word Doc, 800kb)
What is Bluetooth? Is it the technology? Is it the applications?
Is there compatibility amongst itself and other standards? Are
there products? This is an overview of the Bluetooth wireless
technology and its key features. Through exploring the concept of
a Personal Area Network (PAN) discover how the Bluetooth Special
Interest Group (SIG) plays a key role in maintaining standards for
specification of the protocol, profiles, testing and
qualification, interoperability and compatibility. As well as
giving a flavour of the sort of devices and products Bluetooth
Technology can be applied to.

Together the Bluetooth/Mobile Phone Puzzle (3/02) Mobile
phones are seen as the biggest growth sector for Bluetooth radios.
Embedding this radio in a mobile architecture, however, causes big
RF and software integration challenges. Integrating Bluetooth
functionality in to a cell phone is not an easy task. While
Bluetooth and cell phones operate at different frequencies, costly
interference can be encountered in the RF front end. Additionally,
implementing Bluetooth in a mobile architecture forces design
engineers to make some tough hardware and software choices in the
baseband section of a mobile architecture.

- Part 1 Baseband vs. Host Stack Implementation (6/04, 419Kb, PDF)
When two or more independent, non-synchronized Bluetooth piconets
overlap, a scatternet is formed in a seamless, ad-hoc fashion
allowing inter-piconet communication. While Bluetooth stipulates
the use of time-division multiplexing for enabling concurrent
participation by a device in multiple piconets, it leaves the
choice of actual mechanisms and algorithms for achieving this
functionality open to developers. Some implementation proposals
suggest that the host stack handle the complex inter-piconet
communication of a scatternet...

Real World (7/02) Right now in order to get two Bluetooth
devices to work together you generally need to be technically
inclined, and have lots of time to figure out the lengthy setup
and connection process. There are pleasant exceptions, however,
and signs that real world Bluetooth product interoperability and
connection management user interfaces are improving quickly.
- Java Community Process
- JSR 82 Java APIs for
Bluetooth Bluetooth is an important emerging standard for
wireless integration of small devices. The specification will
standardize a set of Java (J2ME) APIs to allow these Java-enabled
devices to integrate into a Bluetooth environment.
- Portable Design Bluetooth
suits mobile information management
- Bluetooth is emerging as the standard that will enable devices
to connect to a global network. Technological innovation is
rapidly transforming how we use and manage information when we're
on the move. As the workplace changes from a stationary office to
a moving platform, the PC era is giving way to mobile devices that
extend our ability to manage and exchange information wherever we
go and whenever we choose. Increasingly, mobile workers need to
access, manage, and update information on demand, regardless of
their physical location.

Application Programming with J2ME and Bluetooth (2/03) This
two-part series of articles will show you how to use J2ME and
Bluetooth to develop next-generation wireless applications for
tomorrow's market. This first article covers the basics of
Bluetooth; the next one will concentrate on using the Java APIs
for Bluetooth Wireless Technology (JSR 82) to develop Java
technology-enabled applications for Bluetooth-enabled devices.
- Part
II: The Java APIs for Bluetooth Wireless Technology (4/03) The
Java 2 Platform, Micro Edition (J2ME) and Bluetooth technology are
two of the most exciting offerings in the wireless industry today.
J2ME, most compact of the three Java platforms, is inherently
portable because it shares the Java "write once run
anywhere" philosophy and thus enhances developer
productivity. Bluetooth is a short-range universal wireless
connectivity standard for electronic appliances and mobile
devices.

versus WLANs If asked to construct a wireless local area
network (WLAN), most IT managers would think of 802.11b wireless
Ethernet technology. Few would consider using another short-range
radio technology, Bluetooth, on its own or in combination with
802.11b-based equipment. The reason for its neglect is that
Bluetooth has been marketed as a technology for linking devices
such as phones, headsets, PCs, digital cameras and other
peripherals, rather than as a technology for LANs. However,
Bluetooth could become a serious WLAN option, partly because a lot
more Bluetooth devices will be released over the next 12 months.
But IT managers may think twice before supporting this technology
because 802.11b and Bluetooth use the same 2.4GHz spectrum to
transmit data, interference is a real possibility.

SOC and Silicon Articles:
- Grasping Particle-Beam
Isolation Technology, and Winning in Coming SOC Era (PDF)
- The advent of ultra deep sub-micron silicon technology (of gate
length 0.13 µm and below) has triggered a strong motive to
integrate multiple existing functions onto a single chip, called
system-on-a-chip or SOC. This is desirable from the consumers’
perspective, as it will, eventually, reduce the overall system
cost, size, and power consumption dramatically while enhancing
product performance and functionality. However, this worldwide
trend provoked mixed feelings among production firms. On the
bright side, it gives enormous hopes for a variety of potentially
large markets; on the dark side, SOC-related problems are much
more involved and deceiving than at first glance. Aside from
complicated verification issues related to IP (intellectual
property) re-use integration in general, it is technically very
challenging to place extremely noise-sensitive RF or analog blocks
side by side with relatively noisy digital (or even analog) blocks
on the same silicon (or SiGe) substrate.
