With more and more cars coming equipped with Bluetooth technology, imagine the convenience as well as safety of conversing with family, friends and business associates without taking your hands off the wheel. Won t it be nice to be able to wirelessly navigate even the most difficult routes in foreign cities using Bluetooth and GPS technologies? Now you can. Bluetooth is here! 4

5 The Freedom of Bluetooth Introduction Bluetooth is a standard for a small, low-cost, power efficient radio chip that can be used by computers, printers, mobile phones, headsets, headphones, and numerous other consumer electronics. This technology allows multiple devices to communicate with each other, or one device can control and manage several other devices. Background Much in the same way that King Harald Bluetooth united Denmark and Norway, Bluetooth was designed to unite computers, phone equipment and many other electronics devices. Back in 1994, Ericsson Mobile Communications began a feasibility study on an inexpensive low-power radio solution between cell phones and phone accessories. Four years later, Ericsson, along with Nokia, IBM, Toshiba and Intel formed the Bluetooth Special Interest Group (SIG). This association represented leading companies in mobile telephony, notebook computers and a market leader in digital signal processing technology. Bluetooth was positioned as easy to use link that would create a personal area network. Immediately, the media and public raised unrealistically high expectations even before the first hardware products arrived. The technology initially delivered more failures than successes, with numerous bugs, complexities, and incompatibilities. By 1999 the year Bluetooth Spec 1.0 was introduced 5

6 The Freedom of Bluetooth companies had joined the SIG. A year later, when spec 1.1 was accepted, the Group boasted well over 1,000 members and a full 2000 companies had become involved by Fall 2003 when Bluetooth Spec 1.2 was announced. Today, the Bluetooth SIG counts among its members 3,400 companies. Instant Multi-device Network A Bluetooth to USB Adapter such as IOGEAR s GBU311 or GBU211 allows any computer to become a Bluetooth-enabled computer, and be able to send to and receive information from a wide variety of other Bluetooth products. 6

7 The Freedom of Bluetooth How does it work? Bluetooth takes the information normally carried by a wire and transmits it at a special frequency to another Bluetooth device. Both the sending and receiving devices have what is called a Bluetooth receiver chip, which translates data into a wireless transmission and then back to normal again, depending on if it is sending or receiving data. 7

8 The Freedom of Bluetooth Bluetooth vs. WiFi Perhaps pitting these two wireless technologies against each other is unfair since both offer unique advantages and complement rather than compete with each other. WiFi offers a means to wirelessly connect one or more computers to each other and to a router so they can access the Internet. WiFi range can reach longer distances than Bluetooth and transfers data faster as well. Bluetooth is a short-range wireless medium but offers a means to link not just computers, but PDAs, headphones, headsets, printers and other technology with each other.

You can sync the address book on your computer with your cell phone. Using your Bluetooth headset, you can wirelessly communicate with friends using SKYPE, Vonage or other Voice over IP (VOIP) phone system. A computer can use both Bluetooth and WiFi simultaneously. A wireless WiFi connection can connection the computer to the Internet access point, while Bluetooth adapter can allow the computer to print wirelessly and well as speak with other Bluetooth-enabled devices such as a headset, PDA, etc. Designed for infrequent mobility IP-based data transmission Medium range High data rate Ideal choice for WLAN Yes No Extremely high data rate Range is limited by cables Perfect choice for LAN Expensive Power-hungry Only for network cable replacement Wired cable solution 9

10 The Freedom of Bluetooth Bluetooth Specs and Classes Since its introduction in 1994, the specifications for Bluetooth have continuously improved. Bluetooth 1.0 and 1.0B The original Bluetooth specifications had numerous problems and the various manufacturers had great difficulties in making their products interoperable. Because of the way Bluetooth devices had to communicate with each other, anonymity was impossiblel Bluetooth 1.1 In version 1.1 added support for non-encrypted channels was added Bluetooth 1.2 This version is backwards compatible with 1.1. Major enhancements include: Adaptive Frequency Hopping (AFH), which improves resistance to radio interference by avoiding the use of crowded frequencies Higher transmission speeds Bluetooth 2.0 This version is backwards compatible with 1.x. The main enhancement is the introduction of Enhanced Data Rate (EDR) of 2.1 Mbit/s. 3X faster transmission speed (up to 10 times in certain cases). Lower power consumption 10

11 The Freedom of Bluetooth Classes Bluetooth devices are known as Class 1, Class 2 or Class 3. Class Range Power consumption Applications 1 Up to 330 ft (100m) Greater Typically used by devices that require extended range, such as Bluetooth to USB Adapters (IOGEAR GBU311) and more. 2 Up to 66 ft (20m) Lesser Typically used by devices which do not require great range and should conserve notebook battery power, such as Bluetooth MiniMice (IOGEAR GME225B), Bluetooth GPS (IOGEAR GBGPS201), Printer Adapters (IOGEAR GBP201), and more. 3 Up to 33ft (10m) Least Used by devices require very short range, such as cell phones, PDAs 11

12 The Freedom of Bluetooth What can I do with Bluetooth? Wirelessly Transfer Data Transfer pictures, files, s, and other data between Bluetooth devices such as desktop computers, PDAs, cell phones, printers, notebooks, and more Print files, documents and pictures from your computer or PDA Use the address book on your PDA to dial phone numbers on your cell phone Hot Sync a PDA or mobile phone with your computer without plugging in wires; when you update your calendar or contact list, all your other Bluetoothenabled devices will update automatically Compute Wirelessly Use a Bluetooth-enabled mouse Print to a Bluetooth-enabled printer Network to other local Bluetooth-enabled computers 12

GPS The Bluetooth GPS receiver allows you to receive positioning data from satellites and deliver the data to mobile computing devices wirelessly via Bluetooth. 18

19 Connecting with Bluetooth Software and hardware requirements To Bluetooth-enable a computer, the following are required: One Bluetooth USB Adapter such as IOGEAR s GBU311 and GBU211 One available USB port One CD-ROM Drive For PC: Windows 2000/XP For Mac: Mac OS X (10.3.9) or better We invite you to keep up to date on the latest IOGEAR Bluetooth communication innovations at 19

20 Connecting with Bluetooth Can anyone connect with my Bluetooth devices? You can easily connect with your friends and colleagues Bluetooth devices to share information, pictures, Internet access, and a wide range of other uses. However, Bluetooth features three types of built-in security to prevent unwanted connections with your equipment: Pairing, Encryption, and Pass Key Protection Bluetooth Built-in Security: - Pairing - Encryption - Pass Key Pairing This function enables Bluetooth devices to remain permanently linked to each other. Even if a paired Bluetooth device is turned off, or just out of range, it will be visible to the Bluetooth devices it has been paired with when it is powered on again or comes within range. 20

21 Connecting with Bluetooth Encryption Bluetooth features 128-bit security encryption to make sure that no other devices can receive transmissions that you send. Pass Key This is a unique, case-sensitive password that is set by the user and is required in order to access and communicate with the Bluetooth device. The Pass Key is continually incorporated into the 128-bit Encryption; also it reinforces pairing by only allowing devices to pair if the password matches. Bluetooth on the Road As noted earlier, nowhere is Bluetooth more at home as on the road. By eliminating wires, Bluetooth allows drivers to converse telephonically without jeopardizing safety. Voice operated Bluetooth-enabled cell phones and Bluetooth headsets were quite literally made for each other, and give drivers complete freedom to get to their destination safely while staying in touch. Car manufacturers from BMW to Chrysler to Toyota equip their cars with Bluetooth technology as standard equipment. With a compatible Bluetooth-enabled phone, drivers can place and answer calls as well as browse and select phone book contacts simply by using buttons often found on steering wheels and keys on their radios. 21

22 Connecting with Bluetooth On some vehicles, it s even possible to activate these functions using voice commands that interface with the vehicle itself. Just say, Phone home, and you ll be connected in moments, without having to lift a finger off the wheel. Getting lost while driving is becoming a thing of the past with Bluetooth GPS systems such as IOGEAR s GBGPS201. This palm-sized device wirelessly communicates with GPS satellites and Bluetooth-enabled PDAs, notebook computer, or car-mounted PCs that are gaining in popularity. Guidance information is transmitted from the satellites to the GPS and wirelessly from the GPS to the PDA/notebook/dashboard-mounted PC monitor. These GPS systems can be carried from one vehicle to another, including rental cars, ending frustration and optimizing business travel. 22

23 Bluetooth Networking Can I use Bluetooth to create a network? All that is needed to connect to a network is a Bluetooth enabling device, such as IOGEAR s Bluetooth to USB Adapter. 23

24 Bluetooth Networking As many as eight Bluetooth devices can be connected at once! For example, you can have a couple of Bluetoothenabled computers, a mobile phone, a video camera, a printer, a PDA, and a Bluetooth access point all working together to share an Internet connection, synchronize address books and calendars, share a printer, and perform various other functions. If there are more than eight Bluetooth devices in the same area, only eight of them can be linked together via pairing to communicate at the same time. Any other devices will not interfere with the Bluetooth network. 24

25 Bluetooth Networking Will Bluetooth interfere with other wireless devices? Bluetooth operates at the 2.4 GHz range. While wireless Ethernet and some cordless phones do share the 2.4 GHz band range, Bluetooth is designed to operate in a noisy-frequency environment; moreover, by using constant frequency hopping, any possible interference would be minimal and intermittent. Summary Bluetooth offers a very affordable, high-speed, secure, simple and dependable way to communicate and share data wirelessly. Today Bluetooth technology spans the technology, automotive, medical, gaming, entertainment, communications and other industries worldwide. That s why companies including Lexus, Texas Instruments, Apple, Hewlett Packard, BMW, Sony Ericsson, Chrysler, Microsoft, Motorola, Nokia, Toshiba, and hundreds of other developers are introducing more and more new Bluetooth-enabled products that incorporate this new proven standard in communications.
