Bluetooth IEEE 802.15.1 vs. Wi-Fi IEEE 802.11 in networking

Bluetooth and Wi-Fi have many applications in today's offices, homes, and on the move: setting up networks, printing, or transferring presentations and files from PDAs to computers. Both are versions of unlicensed wireless technology.

Wi-Fi is intended for resident equipment and its applications. The category of applications is outlined as WLAN, the wireless local area networks. Wi-Fi is intended as a replacement for cabling for general local area network access in work areas.

Bluetooth is intended for non resident equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any ambience.

Operating systems of Bluetooth

* Linux: Initial. A2DP support was added to BlueZ in version 3.15. The instructions to set up A2DP can be found in the BlueZ Wiki.
* Mac OS X: As of version 10.5, Mac OS X includes native support for A2DP on Bluetooth-equipped Macs.[3] Version 10.4 does not support A2DP, but can be hacked to enable limited functionality.[4] Softick Audio Gateway for Mac OS X also supports A2DP. The iPhone variant of OS X supports this, but only in version 3.0.
* iPhone: Version 3.0 of the iPhone operating system, due to be released Summer 2009, support A2DP.
* Palm OS: A2DP support was introduced in 2006 by Softick with their Softick Audio Gateway shareware program.
* Symbian Series60: Devices running Series60 3rd Edition FP1 (S60v3.1/Symbian 9.1) and newer support A2DP [5]
* Motorola P2K: Motorola L9 running on P2K supports A2DP Profile.
* UIQ: UIQ 3.0 (Symbian 9.1) and newer support A2DP.[5]
* Windows Mobile (previously Pocket PC): Version 5.0 and newer (with AKU 2.0), thus far based on the Windows CE 5.0 kernel, fully support A2DP if an appropriate device is present.
* Windows XP: Does not natively support A2DP, but newer Bluetooth USB dongles and built-in adapters include drivers with A2DP support.[6]
* Windows Vista: Supports A2DP after installing an April 2007 update to the Bluetooth stack, which enables A2DP for supported dongles.[7] No update has been made available through Microsoft as of Feb. 13, 2008, though a Widcomm update may be available to some.
* Windows 7: Supported.
* BlackBerry: Supports A2DP in Operating System 4.2.
* Android: Not supported until cupcake release.[8]

[edit] Audio/Video Remote Control Profile (AVRCP)

This profile is designed to provide a standard interface to control TVs, Hi-fi equipment, etc. to allow a single remote control (or other device) to control all of the A/V equipment to which a user has access. It may be used in concert with A2DP or VDP.

It has the possibility for vendor-dependent extensions. Additionally, with the version 1.3 release of the specification, there is now capability to transmit information on the status of the music source (playing, stopped, etc), including information on the track itself (artist, track name, etc).

[edit] Basic Imaging Profile (BIP)

This profile is designed for sending images between devices and includes the ability to resize, and convert images to make them suitable for the receiving device. It may be broken down into smaller pieces:

Image Push
Allows the sending of images from a device the user controls.
Image Pull
Allows the browsing and retrieval of images from a remote device.
Advanced Image Printing
print images with advanced options using the DPOF format developed by Canon, Kodak, Fujifilm, and Matsushita
Automatic Archive
Allows the automatic backup of all the new images from a target device. For example, a laptop could download all of the new pictures from a camera whenever it is within range.
Remote Camera
Allows the initiator to remotely use a digital camera. For example, a user could place a camera on a tripod for a group photo, use their phone handset to check that everyone is in frame, and activate the shutter with the user in the photo.
Remote Display
Allows the initiator to push images to be displayed on another device. For example, a user could give a presentation by sending the slides to a video projector.

A Bluetooth profile

A Bluetooth profile is a wireless interface specification for Bluetooth-based communication between devices. In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the desired services. A Bluetooth profile resides on top of the Bluetooth Core Specification and (optionally) additional protocols. While the profile may use certain features of the core specification, specific versions of profiles are rarely tied to specific versions of the core specification. For example, there are HFP 1.5 implementations using both Bluetooth 2.0 and Bluetooth 1.2 core specifications.

The way a device uses Bluetooth technology depends on its profile capabilities. The profiles provide standards which manufacturers follow to allow devices to use Bluetooth in the intended manner.

At a minimum, each profile specification contains information on the following topics:

* Dependencies on other profiles
* Suggested user interface formats
* Specific parts of the Bluetooth protocol stack used by the profile. To perform its task, each profile uses particular options and parameters at each layer of the stack. This may include an outline of the required service record, if appropriate.

This article summarizes the current definitions and possible applications of each profile.

Bluetooth profiles

In order to use Bluetooth, a device must be compatible with certain Bluetooth profiles. These define the possible applications and uses of the technology.

Uses of Bluetooth

Bluetooth is a standard and communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters) based on low-cost transceiver microchips in each device.[5] Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other.[4]

Implementation

Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 frequencies. In its basic mode, the modulation is Gaussian frequency-shift keying (GFSK). It can achieve a gross data rate of 1 Mb/s. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, Global Positioning System (GPS) receivers, digital cameras, and video game consoles through a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group (SIG). The Bluetooth SIG consists of companies in the areas of telecommunication, computing, networking, and consumer electronics.[4]

Origin of the Bluetooth logo

The Bluetooth logo design merges the Germanic runes analogous to the modern Latin letters H and B: (for Harald Bluetooth) (Hagall) and (Berkanan) merged together, forming a bind rune.

Origin of the name

The word Bluetooth is an anglicized version of Old Norse Blátönn or Danish Blåtand, the name of the tenth-century king Harald I of Denmark and Norway, who united dissonant Scandinavian tribes into a single kingdom. The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard.[1][2][3]

It is possible that the name may have been inspired less by the historical Harald, than by the loose interpretation of him in The Long Ships by Frans Gunnar Bengtsson, a Swedish Viking-inspired novel.[citation needed]

Bluetooth

Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs). It was originally conceived as a wireless alternative to RS232 data cables. It can connect several devices, overcoming problems of synchronization.

Palm OS

Significant player with strong enterprise following in the important US market.

Pocket PC and Microsoft Smartphone

Ideal for enterprise applications with an existing PC infrastructure and options for significant development investment. However not cross platform and limited to Microsoft devices.

BREW

Ideal for deploying applications for deployment on CDMA-based networks (also supports GPRS/GSM models) with a deployed Brew Content Platform especially if OTA app deployment is desired. Little penetration in Europe.

.NET Compact Framework

Ideal for deployment on homogeneous Pocket-PC devices. However not cross platform and limited to Microsoft Windows Mobile devices.

Python

Ideal for initial prototyping and concept testing when functionality falls outside Java ME.

Lazarus

Ideal for prototyping and quickly developing database powered applications. Also useful for porting Object Pascal software to mobiles. Can access the native APIs when translated headers are available.

iPhone

The iPhone and iPod Touch SDK uses Objective C, based on the C programming language. Currently, is only available on Mac OS X 10.5 and is the only way to write an iPhone application. All applications must be cleared by Apple before being hosted on the AppStore, the sole distribution channel for iPhone and iPod touch applications. However, non-Apple approved applications can be released to for jailbroken iPhones via Cydia or Installer.

BlackBerry

supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services as well as a multi-touch interface. It has a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type. The BlackBerry devices soon took a dominating position on

the north-american smartphone market. Also important for BlackBerry are the BES (Black Berry Enterprise Server) and the Mobile Data System (BlackBerry MDS).

Android

Recently announced by the Open Handset Alliance, whose 34 members include Google, HTC, Motorola, Qualcomm, and T-Mobile, Android is a new Linux-based platform currently available only as a developer pre-release. Although it does not yet have any fielded implementations, its support by 34 major software, hardware and telecoms companies makes it likely that it will be rapidly adopted from 2008. The Linux kernel is used as a hardware abstraction layer (HAL). Application programming is exclusively done in Java. You need the Android specific Java SDK. Besides the Android Java Libraries it is possible to use normal Java IDEs.

Symbian

Very powerful for general purpose development. The Symbian based S60 platform is strongly supported by Nokia with some support from other device manufacturers. In Japan NTT DoCoMo's Symbian based MOAP platform is also well supported by a number of manufacturers (Fujitsu, Sony Ericsson Japan, Mitsubishi and Sharp amongst others). It should be noted, however, that MOAP is not an open development platform. Another Symbian based platform, UIQ, is less well supported (principally by Sony Ericsson and Motorola). Currently large device deployments in Europe and Japan, with little penetration in the US market.

Java ME

Ideal for a portable solution, if the Java ME platform provides the needed functionality. Good for vertical applications that must be portable. Device-specific libraries exist for many devices and are commonly used for games, making them non-portable. Applications (including their data) cannot be larger than around 1 MB if they are to run on most phones. They must also be cryptographically signed in order to effectively use many APIs such as the filesystem access API. This is relatively expensive and is rarely done, even for commercial applications.
