With a Bluetooth mobile phone

The PC Card's XJACK antenna delivers clear, interference-free reception,* while the USB adapter's unique form factor gives Bluetooth connectivity to notebook and desktop PCs with a USB port. Bluetooth is an open, global standard for radio links that provides affordable wireless connections between PCs, handhelds, mobile phones, printers, and many other devices, along with access to network resources. The Bluetooth specification defines a low-power radio link optimized for secure short-range connections, and lays out standard steps for connecting various types of devices. Bluetooth radios--which can be incorporated into most any electronic device--offer a univer-sal wireless communication link that enables reliable interoperation between devices from different manufacturers. Bluetooth radios operate in the 2.4 GHz spectrum. With a Bluetooth mobile phone, users can dial-up the Internet** or connect to the LAN through a Bluetooth access point. As a member of the Bluetooth

This course introduces the JSR 82 Java APIs for Bluetooth, an optional J2ME package defined by the Java Community Process that provides a standard API for Bluetooth connectivity. It starts by introducing the Bluetooth technology, followed by the Java APIs for Bluetooth, and how to use them. All Bluetooth low-level implementations must satisfy a set of requirements with respect to the supported Bluetooth profiles and protocols, as follows: Table 1. In addition, Bluetooth devices must also support what is called the Bluetooth Control Center (BCC), which is the central authority for local Bluetooth device settings. The BCC is not part of the Bluetooth Java API itself, but the Bluetooth API depends on the BCC for things such as device level configuration and security settings. Using the Java APIs for Bluetooth consists of initializing the Bluetooth stack, discovering devices or services that are in proximity, open and close and waiting for or initiate

BluetoothAndMIDP

This technical report deals with the integration of Bluetooth into the framework of Java2 Micro Edition (J2ME). In the case of Bluetooth, the scheme of the URI should be "bluetooth:". Based on that syntax, the following examples could be used to establish a connection between a bluetooth equipped mobile information device (MID) and another bluetooth station: Bluetooth Profiles The approach shown here may be usefull in all scenarios, where the bluetooth connection can be seen as a channel for input and output streams. Protocol Handler The introduction of the bluetooth scheme ("bluetooth:") requires the implementation of a class exactly named com.sun.midp.io.j2me.bluetooth.Protocol.class. Bluetooth Connection Interface The bluetooth specific functions like device discovery etc. are not accessible by the CLDC or MIDP standard connection interfaces. Each time the device discovery is performed by calling the function deviceDiscovery() of the BluetoothConnection interface, a

Among the various wireless technologies available to-day, Bluetooth stands out as the most promising for use in low-power sensor networks. This is especially true for large networks of sensors with low data rates, where Blue-tooth's low power Hold, Sniff, and Park modes could be utilized during periods of low activity to reduce power con-sumption. We in-troduce a novel polling algorithm called Adaptive Share Polling (ASP) that is designed to perform well when the network consists of sources sending short data packets at constant rate that may ﬂuctuate over time. In ASP, the scheduler at the master implicitly learns the share of the bandwidth that needs to be allocated to each of the slaves in order to meet the latency and/or power requirements of the application. Our simulation results show that signiﬁ-cant power savings can be achieved in slaves whose data rates do not approach capacity of a Bluetooth piconet, and in masters when the composite data rate of the piconet

Atlantis: Location Based Services with Bluetooth

Thus end users will be hesitant to carry cumbersome and expensive GPS devices when they can multitask by using a Bluetooth enabled PDA, which they must carry anyway. Current known attempts at implementing a position aware computing service using Bluetooth appear to be limited to highly controlled, unobstructed environments. They also seem to only take into account the types of devices with low range that do not implement the Bluetooth protocol's well defined method of power consumption control. The motivation and objective of this project is to devise a centralized framework for predicting location and offering location based services for Bluetooth enabled devices. In an effort to offer context aware, location based services using the Bluetooth platform specification, a centralized framework has been developed that allows location approximation via sensor data from a ubiquitous Bluetooth sensor network consisting of numerous base stations. In this arena, Bluetooth technology

Monthly Asia Report-July

July 2001 Much has been said about the merits of each versus the other, but comparing the two as competing protocols would be a mistake. It is very common to hear someone say that Wi-Fi is better than Bluetooth because 11MB is better than 1.2MB, or because 1200ft range is better than 30. One could just as easily incorrectly generalize that Bluetooth is better since it uses less power and has a smaller footprint. As it happens, both Wi-Fi and Bluetooth meet their design requirements well, but they were not designed to fill the same role. Wi-Fi and Bluetooth are like motor oil and pepperoni. Bluetooth is better suited for: Wi-Fi is better suited for: LAN applications where high bandwidth (>2MB) Installation into low-power devices like phones and PDAs is desirable OEM installation into devices cheaper than $300 Applications where greater range is desirable Applications where high-bandwidth (>700k) isn't necessary An example of the fact that the two protocols serve different

Secure Access Control Using Mobile Bluetooth Devices

If the Bluetooth chip used in the mobile device is properly designed, the power consumption of doing inquiry scans should be negligible compared to continuous inquiries. Another important aspect is that any connection to a Bluetooth device takes power, and if the device is battery powered the lock device will use valuable energy on the given device with any unnecessary connection attempts. We there-fore choose to let the lock device inquiry for 6.4 seconds after an unsuccessful connection. ) there is 99% chance of If there are multiple devices found during the inquiry, the lock device has to choose which one to connect to ﬁrst, since it is only possible to establish a connection to one device at a time in Bluetooth. To limit the number of possible devices to connect to we can also choose to limit the number of devices in range of the lock device, which can be obtained by adjusting the Bluetooth radio on the lock device. Besides the trouble of many other Bluetooth devices

3Com Bluetooth and Wi-Fi

Well, thanks to Bluetooth and Wi-Fi (IEEE 802.11b) wireless technologies, this kind of connectivity is becoming a reality. Bluetooth is an open, global standard for radio links that provides afford-able wireless connections between PCs, handhelds, mobile phones, print-ers, and more, as well as giving these products access to network resources. The Bluetooth specification defines a low-power radio link optimized for secure short-range connections, and lays out standard steps for connecting various types of devices. Bluetooth radios, which can be incorporated into most any electronic device, offer a universal wireless communication link that enables reliable interopera-tion between products from different manufacturers. How Bluetooth Wireless Bluetooth radios operate in the 2.4 GHz spectrum. The Bluetooth specification defines two radio choices: a low-power level with up to a 10-meter range primarily intended for client devices and a high-power level with a 100-meter range for

The Bluetooth technology eliminates the needs for numerous and inconvenient cable attachments for connecting computers, mobile phones, mobile computers and handheld devices. The Bluetooth technology is a result of nine companies (3 COM, Ericsson, Intel, IBM, Lucent, Microsoft, Motorola, Nokia and Toshiba) putting their expertise and achievements toward a common goal for the telecommunications industry. More than 1300 manufacturers all over the world have joined Bluetooth to become the fastest growing industry standard in history. At this pace, Bluetooth technology will be built into most electrical devices that we use today. The Bluetooth technology includes a tiny microchip that is put in digital devices that uses a radio transmitter to make connections instantly. Bluetooth makes network connections fast and easy by connecting to different types of networks through a Bluetooth connection. Another great advantage is that all Bluetooth enabled devices can be set up with

Interference from UWB to Bluetooth & GSM DCS 1800RTCG Project Report 639

This report details the measurements made for RA2/TSU concerning the effects of UWB interference to Bluetooth and GSM DCS 1800. The C/I values being 18 to 19 dB for Bluetooth wanted signals and ~8dB for GSM at 1800 MHz. The Bluetooth equipment was two evaluation kits (to create a transmit and receive link) designed for this system and the GSM tests were performed with a sample mobile phone of modern design. It does, however, use a wide frequency spectrum that covers many other users including Bluetooth and GSM cell phones. As part of the investigation into UWB possible interference into other services for CEPT SE24, this report details the work done to examine the compatibility of UWB signals with Bluetooth and GSM DCS 1800 signals. Three Bluetooth tests were performed :- File transfer with a failure of 10% increase in transfer time for a large (1 Mbyte) file. BER tests using the software in the Bluetooth kit failure being 0.1% BER. Figure 2 shows the
Bluetooth SIG reserve the right to adopt any changes or alterations to the Publication as it deems necessary or appropriate and to adopt a process for adding new Bluetooth wireless profiles after the release of the Publication. The Bluetooth combination keys would be much more appropriate to use for almost any Bluetooth unit and therefore we do not recommend the use of unit keys. Adequate implementation of Bluetooth security and Bluetooth passkey can also prevent illegal use of a stolen headset. Furthermore, the HS implementation should make sure that changing the Bluetooth passkey is only possible over an authenticated and encrypted Bluetooth link or a wired connection. If the Bluetooth passkey for a headset can be changed, it might be good practice to allow someone with physical access to the HS to reset the HS to its original (factory) Bluetooth passkey. This makes it possible for someone to continue to use their headset if they lose or

Bloomington, Minn -- A new line of hearing and balance systems called OTOflex, including the first implementation of Bluetooth technology in an immittance system called OTOflex 100, was launched by GN Otometrics at the American Academy of Audiology convention in Salt Lake City. The new line is designed to eliminate testing equipment that is tethered via wires to computers or other diagnostic hardware, making testing more mobile while reducing space requirements. The new instruments use Bluetooth wireless technology to transmit data between the hand-held units and the computer and software. The hand-held instruments will have a range of about 33 ft. The USB antenna that receives the Bluetooth data snaps into the back of any computer and costs around $40. OTOflex 100 features a full battery of tests including multiple probe-tone tympanometry to 1000 Hz, reflex screening, reflex decay, and eustachian tube testing (intact and perforated). It is capable

A hardware prototype was built and software programs were written to implement the headset profile in the Bluetooth specification. With the use of dynamic Bluetooth links be-tween various mobile devices, a large number of new products and services will become possible. A Bluetooth link, with one side called "the master device" and the other side called "the slave device," uses one channel in each time slot and jumps to another channel in the next time slot. A pair of Bluetooth transceivers forms the wireless link, and each transceiver is connected to a host contro the software protocol stack. To ensure interoperability between Bluetooth devices, the protocol layers and application profiles defined in the Bluetooth Specification need to be followed. Application profiles for different scenarios are also included in the Bluetooth Specification to guide implementa-tion, since devices following the same profile are guaranteed to be compatible with each other [17].

In addition, we conducted a first-time use study of Bluetooth-enabled devices. They were assigned a different task to complete with each pair, including transfering calendar entries, pictures, and personal contact information between devices using Bluetooth wireless technology. Although the subjects were generally unfamiliar with both the specific devices used and Bluetooth in general, most tasks were completed within an arbitrary 40-min limit, and the average task completion time was about 15 min. First-time Usability Testing for Bluetooth-enabled Devices The initial phase of the current set of studies was concerned with determining the interoperability of a large sample of Bluetooth-enabled telecommunications and computer devices. Within this set, some devices and pairs were found to be more-or-less easy to use, readily accepted Bluetooth connectivity, and facilitated rapid transfer of information from one device to the other. The goal of the research was
