What is Bluetooth?

Bluetooth is a worldwide standard for digital wireless communication and data exchange between multiple devices. Bluetooth compliant devices exchange data by establishing a relationship with each other, the first device acting as a client, requests a connection, while the second device acting as a server accepts or rejects that request. Some Bluetooth devices can behave as client and server; however other devices can only behave as a client.

5.5 Bluetooth Applications

5.5.1 Overview

Some built-in Bluetooth applications provide full functionality for a specific task, such as locating other Bluetooth devices or synchronizing two Personal Information Managers. Other built-in Bluetooth applications provide a way for standard Windows applications to accomplish their tasks wirelessly. For example, a Bluetooth application may create a wireless serial connection between computers or provide wireless access to the Internet. The difference between Bluetooth Applications and Bluetooth Services are described as follows: Bluetooth Applications These are software programs running on the Bluetooth-enabled computer that allow the Bluetooth-enabled computer to use the Bluetooth services that are provided by other devices. In the Bluetooth configuration panel, these programs are referred to collectively as Client Applications.
Bluetooth Services These are software programs running on the Bluetooth-enabled computer that provide a service to other devices. In the Bluetooth configuration panel, these applications are referred to collectively as Local Services.
Note: Client Applications and Local Services usually have
coinciding names; e.g., there may be a Fax service and a Fax application.

5.6.1 Notifications

There are three types of notification: Authentication request, also called a PIN code request This notification appears automatically in a balloon over the Windows system tray if a Personal Identification Code is required before a connection can proceed. An audio file can also be associated with the notification. Authorization request, also called a connection request This type of notification can be visual, audio, or both. It notifies you of attempts to access a Bluetooth service on this computer; the connection will not proceed until you click the balloon that appears over the Windows system tray. If the notification balloon is ignored, the connection request will time out and fail. Notification only This type of notification does not effect access in any way; it is solely
for information purposes to let you know that a connection has been established. Example Both Authentication and Authorization request notifications are controlled by whether Secure Connection is enabled for an individual service. An example of how notifications might work when a remote device attempts to access a service on this computer, if all notifications are enabled: Authentication: a balloon notification (audio optional) appears to prompt for a PIN code. If the PIN code does not match the code entered on the remote device, the connection will not be allowed. Once the remote device has been authenticated this notification will not appear again, unless the paired relationship is broken and the devices must re-pair. Authorization: a balloon notification appears and/or a sound file provides audio notification that a remote device is attempting to access a Bluetooth service on this computer. Click the balloon to proceed. A dialog box appears that offers the option of letting the connection proceed this time only or to always allow this particular remote device to use the service it is attempting to access.
Once a connection has been authorized, an additional visual and/or audio notification may appear (if enabled). This notification is for information only to inform the operator that a connection has been established. After two devices are paired (step 1, above), the authentication notification will no longer appear when a connection is attempted. If Always allow is enabled during the authorization process (step 2, above), the authorization notification will not appear on future connection attempts. Connection notification (step 3, above) only happens if it has been enabled on the Notifications tab of the individual service being accessed. Service Access Notification Notifications lets you associate a sound (Windows *.wav file) and/or a visual indication with access attempts by remote devices. A different notification sound can be associated with each local Bluetooth service.

Open Opens the selected file on this computer, using the default application for this type of file. Print Sends the selected file to this computers default printer. Send To 3 floppy (A)the 3 inch floppy drive on this computer Public Folder on My Devicethe Public Folder on this computer. Rename Applies only to empty folders; file names and the names of folders that contain objects cannot be changed using this technique. Cut, Copy, Paste, Delete, Refresh, View & New Standard Windows functions.

5.6.7 Headset Service

The Bluetooth Headset Service allows this computer to provide audio input/output for remote Bluetooth devices. For example, if the remote device is a Bluetooth telephone, this computers microphone and speakers can be used as speakerphone input and output for that device. Note: Windows 98 has limitations. Windows 98 cannot convert audio files with the extension m3u (e.g., myfile.m3u) into the Pulse Code Modulation (PCM) audio format used by Bluetooth headsets; this is a limitation of Windows 98. Other versions of Windows (2000, ME and XP) can translate m3u audio files into the PCM format. Possible solutions are: Upgrade to a newer version of Windows Use an m3u-to-mp3 conversion utility to convert the file(s) into a format that is supported by Windows 98.

Settling on a standard is one of the most important decisions you'll make while putting together your network. The standard you choose influences everything, including the speed, the features, the reach, and the cost of your network. Making sense out of the alphabet soup of wireless technologies can be daunting, but here's a quick guide to what you need to know.
Network standards at a glance
Networking standards 802.11b 802.11a 802.11g Dual band Bluetooth Actual speed 5Mbps 22Mbps 20Mbps 22Mbps 500Kbps Range 150 feet 100 feet 150 feet 150 feet 30 feet Frequency and interference risk 2.4GHz; high 5GHz: low 2.4GHz; high 2.4GHz 5GHz; varies 2.4GHz; high Hot-spot access Excellent Poor Excellent Excellent Poor Power drain Moderate High Moderate Moderate Low Cost Low High Moderate High Moderate

802.11g

The 802.11g standard, long touted as the high-performance successor to 802.11b, was ratified in June 2003, but networking manufacturers flooded the market with 802.11g gear months before the final specification was approved as a standard. Most of the gear that was sold prior to ratification will need a firmware upgrade to bring it up to the final spec. 802.11g has two features that many believe will make it the new dominant Wi-Fi standard: great throughput at around 22Mbps and backward compatibility with 802.11b. That's right; 802.11g operates at the same frequency as 802.11b (2.4GHz) and is backward compatible with the granddaddy of Wi-Fi specs. This makes 802.11g the obvious choice not only for anyone building a new network, but also for those interested in adding onto or gradually upgrading a preexisting 802.11b network. The only downside to 802.11g is the fact that it uses a crowded slice of the spectrum, with room for only three nonoverlapping channels. This will make 802.11a a better choice for some environments, especially those populated with devices that share the 2.4GHz spectrum, such as cordless phones, baby monitors, microwave ovens, and Bluetooth radios.

802.11g facts Better range than that of 802.11a products Much faster than 802.11b products Low cost Subject to interference from other 2.4GHz devices Only three nonoverlapping channels Buffalo AirStation 54Mbps wireless broadband router

802.11b

The price of 802.11b gear has dropped dramatically over the last year. This gear operates at 2.4GHz and offers a real-world throughput of around 5Mbps at close range. In a typical indoor environment, without a lot of metal, 802.11b equipment can generally maintain a solid connection up to about 150 feet. It is also fully compatible with the faster 802.11g standard. The weaknesses of 802.11b are its comparatively low throughput and the potential for interference with other gadgets that share the
2.4GHz band, such as cordless phones, security radios, and microwaves.
802.11b facts Better range than 802.11a products More than adequate throughput for broadband sharing at around 5Mbps Slower than 802.11a and 802.11g Broad compatibility Low cost Subject to interference from other 2.4GHz devices Only three nonoverlapping channels
Proxim Orinoco World PC Card

802.11a

The 802.11a standard has a couple of advantages over the more prevalent 802.11g. It runs at a less populated frequency (5.15GHz to 5.35GHz), making it less prone to interference, and its practical throughput is about four times greater than that of 802.11b, typically clocking in at around 22Mbps. This gives it a lot more elbowroom than 802.11b for streaming digital audio and video or transferring large files over the network, with bandwidth left over for Internet sharing. Some manufacturers offer proprietary turbo modes that can push throughput even higher. 802.11a's downside is its shorter range. Because 802.11g and 802.11a operate at different frequencies, they can't talk directly to one another, which is why if you have an 802.11a adapter, you cannot connect to most hot spots. Another weakness is the increased power drain of the 5GHz radio, as compared to its 2.4GHz counterparts.
802.11a facts Great throughput at around 22Mbps or higher Operates at 5GHz Low risk of interference from other devices Eight nonoverlapping channels Higher cost than that of 802.11b and 802.11g Intel Pro/Wireless 5000 LAN access point

Dual band

Wouldn't it be nice if you could get all of the 802.11 standards into a single device? The latest wave of dual-band networking equipment gives you just that. 802.11a/b/g gear operates at both 2.4GHz and 5GHz and gives you the advantages of all three standards. You get the speed and the resistance to interference of 802.11a, the broad compatibility and the increased range of 802.11b, and the increased throughput of 802.11g--but you pay for it. Dual-band gear can cost more than twice as much as its single-band counterparts, but for some, the added flexibility will be worth the heftier price tag.

Linksys WRT55AG

Bluetooth
Bluetooth offers more flexibility than Wi-Fi but on a smaller scale. Its throughput is a poky 500Kbps, and its range is just a couple dozen feet, but devices with a Bluetooth radio and an antenna can speak to each other with little or no preparation. Meeting attendees can immediately transfer files across a conference table using their Bluetooth-equipped notebooks, or they can send a file to a Bluetooth-equipped printer without downloading drivers. Bluetooth may soon be standard equipment on many cell phones and handheld computers. There's even talk of putting Bluetooth into home appliances. But for all the theoretical benefits of Bluetooth, the reality is that it's currently a mess of incompatible hardware and software. Because Bluetooth operates at 2.4GHz, it is subject to the same interference problems as 802.11b and 802.11g.
Actiontec USB Bluetooth adapter
Bluetooth facts Not compatible with 802.11 standards Slow throughput at around 500Kbps Expensive Short range of about 30 feet Few Bluetooth devices or services Interferes with other 2.4GHz devices Low power requirements

HomePlug

Power-line gear may be the best-kept secret in home networking. Though overshadowed by Wi-Fi, power-line networking (also known by the Powerline Alliance's name of HomePlug) is a good solution either as an alternative to wireless or as a way to extend a wireless network to the far reaches of a home. Devices based on the HomePlug standard use your home's electrical wiring to connect a digital network. At throughput speeds of around 5Mbps, HomePlug routers and adapters are plenty fast enough to share a broadband connection between a few computers. The power-line solution is also a great way of connecting wireless access points in a large house or building.
HomePlug facts Practical throughput speeds of about 5Mbps Inexpensive Great for environments with 2.4GHz or 5GHz cordless phones Guaranteed interoperability between HomePlug devices

Gateway PLU-300

Ethernet
Nothing tops Ethernet for speed and reliability, and Ethernet also has the advantage of being a lot cheaper to deploy than power line or any flavor of wireless. Most computers already have Ethernet adapters built in, but unfortunately, most homes do not. Still, if you are after high bandwidth, it's worth considering pulling Ethernet cable through your home. Even if you decide not to cable your home for Ethernet, you might find that an Ethernet hub or switch is a good complement to your wireless network. In fact, many wireless routers come with a four-port Ethernet switch built in.

Figuring out what gear you'll need to build your network can be a challenge. We'll help you put together the pieces of the puzzle.

Routers

Routers act as the gateway between your broadband connection and your home network. Wireless routers come in various configurations, but most are amalgamations of a four-port wired Ethernet switch and a wireless access point. As the name implies, these devices route traffic between your network and the Internet. Most include built-in DHCP servers that automatically assign the right IP address information to each computer on your local-area network, or LAN. A separate WAN, or wide-area network, interface on the router connects your entire home or office network to your broadband modem, allowing you to share your Internet connection through the router. Most routers also have firewall capabilities, and some include more advanced security features. Some routers even have an integrated cable or DSL modem, eliminating your need for two separate devices.

Access points

The access point is the hub of a wireless network and the central transit point for all of the data flowing between your wireless network and your wired network. There are as many types of access points as there are networking standards: 802.11b, 802.11a, 802.11g, and Bluetooth. Wireless access points do not offer the rich feature set and the high configurability of most routers because they are designed to add a wireless extension to your network and not to play the role of a central gateway. Nevertheless, access points do typically include some security features, such as encryption.

Adapters

An adapter connects your computer or your PDA to a network. If your computer doesn't already have the adapter that you need built in, you can add one. As with access points, there are as many types of adapters as there are networking standards--802.11b, 802.11a, 802.11g, dual band, and Bluetooth--and each type comes in a variety of shapes and sizes, including PC Cards, PCI and mini-PCI, USB, CompactFlash, and SD. Some wireless adapters are decked out with special features, such as retractable or removable antennae, encryption support, or connection-monitoring software. Before making your purchase, always confirm that the adapter is compatible with your operating system. If you plan to use an adapter at work, you should also check to ensure that it is compatible with any encryption schemes in use, such as LEAP or WPA.

Switches and hubs

Ethernet is the glue that holds together most networks. It's fast and cheap, and it is integrated into just about everything. If you need to expand your network, an Ethernet hub or switch can come in very handy since most desktops and notebooks include a built-in Ethernet adapter. Accordingly, most wireless broadband routers come with a three- or four-port Ethernet switch built in, allowing you to connect to the router via a fast, wired Ethernet connection. Switches and hubs perform similar functions, but switches can handle multiple simultaneous users without any significant decrease in network throughput.
You may already have a home network and now want to connect it with your friend's network across the street, or perhaps you want to create a public hot spot to draw customers to your business. With the right equipment, you can expand your network for more extensive coverage in your own home or bridge the digital divide in your neighborhood by starting a community network.

Repeaters

As a digital signal travels down a cable or through the air, it gradually gets weaker. To get the signal to go farther, you need a device that can pick it up, then send it off again at full strength. Repeaters do just this. Repeaters are easy to confuse with bridges, and in fact, some access points and bridges include a repeater mode that allows the device to receive a signal from another access point and repeat it to adapters or other access points within its range. However, some bridges are capable only of talking to other bridges. Look carefully at the feature set to see if the product you are considering offers a repeater mode.
Things to consider about a repeater Is it compatible with your other repeaters and access points? Does it have a removable antenna or an external connector? How many Ethernet ports, if any, does it have? Does it include both point-to-point and point-to-multipoint modes?
Buffalo Wireless repeater

Wireless bridges

A bridge connects two or more wireless networks in a large home, across the street, or across campus. Bridges attach networks together either through point-to-point or point-to-multipoint connections. Not long ago, bridges were expensive high-end products, but now you can find consumer bridges at very reasonable prices. Unfortunately, this technology varies based on the chipset and the firmware, so bridges tend to work only with other bridges of the same type and model. Before you lay down your cash, make sure that the bridges you're considering will work together.

Antennae

A good way to increase the range of your wireless network is to add an antenna that is better suited to your needs. Antennae transmit signals in different ways. For example, if you want to share Internet access with your immediate neighbors, install an omnidirectional antenna on your roof. If you want to cover a specific location, such as the park across the street, a directional antenna works best. For faraway areas, you will need a high-gain antenna capable of bridging the gap. In general, the higher the gain of the antenna, the further its reach will be. Look for an antenna that has been certified by the FCC to work with the router, the access point, or the adapter that you plan to use with it. Also be sure that the antenna has the right type of connector to mate with the connector on your networking gear.
Things to consider about antennae Do you want to cover a broad area or make a long-distance link to another location? What is the gain of the antenna? What type of antenna connector do you need? Is the antenna certified by the FCC for use with your equipment?
Buffalo AirStation extended range antenna

Power-line bridges

A power-line bridge can take your wireless network into places it might not otherwise be able to penetrate. For example, you may have a room with a wall that is covered with metal shelving. This would probably put it outside the reach of your wireless router. However, you can use a pair of power-line bridges to connect your router to an access point via your electrical wiring, which lets you add wireless connectivity even to those hard-to-reach areas. You can buy power-line bridges with both USB and Ethernet interfaces, so make sure you get the right interface for the device you intend to connect it to.
Things to consider about power-line bridges Does it have the right interface for your access point or router? Is the bridge HomePlug compliant?

The components and the layout of your network will determine what you'll need to secure local computers, but some things are musts for any network that is connected to the Internet. A few simple preemptive measures can go a long way toward protecting your data and keeping your systems safe.

Basic security features

The first step to securing your network is to use the standard features that are built into your gear. Many networking devices come with security features that will protect your network against hacker attacks. If you are buying a broadband router, look for one with a NAT firewall and MAC address filtering. NAT firewalls conceal your network behind the router, and MAC address filtering allows you to grant or deny access to your network to specific machines. NAT usually runs automatically and requires no configuration. MAC address filtering requires you to enter the MAC addresses of the computers you want to allow or deny. Wireless-networking devices typically include WEP or WPA encryption. Both forms of encryption help protect your network, but WPA is much more secure than WEP. To implement WEP or WPA, you'll need to enter an encryption key on all of the wireless devices on your network; the product user manual typically includes a detailed explanation of how to do this. Some wireless devices add authentication schemes, such as 802.1x or LEAP, but these technologies are better suited to large enterprises than home or small-office use.
Things to consider about basic security features Do you have a NAT firewall between the Internet and your network? Have you enabled MAC address filtering? Have you enabled WPA or WEP encryption for your wireless clients? Do you need 802.1x or LEAP to connect with your office LAN?

Antivirus software
A home or office network makes it easy for you to share files between computers, but that also makes it easier for viruses and worms to wind their way through your computers. Fortunately, you can immunize your computers with antivirus software. Antivirus software detects and eradicates viruses before they have a chance to spread. If you plan to connect your network to the Internet, antivirus software is a must.
Things to consider about antivirus software How long is the software automatically updated to detect new viruses? How fast does it scan for viruses? Does it scan and clean instant-messenger attachments? Does it come with a software firewall? Does virus eradication require your involvement?

Software firewalls

When you open an e-mail message, an e-mail server somewhere on the Internet is sending the data to a certain port on your computer. A Web server uses a different port on your computer to send you a Web page, and an instant messenger yet another to send you a message. These are software ports, so you can't see them, but trust us, they're there. A firewall manages the data traffic coming to and flowing from your computer on specific ports--sometimes allowing data to get through, sometimes blocking it, and other times asking you if you want to permit a connection that is about to be opened. Most firewalls include a general set of rules about what is and what is not allowed, others may allow you to set your own rules.
Things to consider about firewall software Is it easy to install? Does it come with phone support? Does it pass CNET Labs' firewall tests? Does it come with antivirus software?
Zone Labs ZoneAlarm Pro 4.0

Hardware firewalls

A hardware firewall works the same way as a software firewall but has certain other advantages. Whereas a software firewall must be installed on each computer in your network, a hardware firewall centralizes the control of connections between your network and the Internet, so you can be sure that all of the machines on your network are playing by the same rules. Hardware firewalls also use their own processors for port filtering and encryption tasks, which means that there is little or no resource drain on the computers in your network, giving you better overall performance. Some firewalls also allow you to set up VPN connections from the Internet to your personal LAN, providing you with a secure way to access your computers while you're on the road.
Things to consider about hardware firewalls How many ports does it have? Does it perform stateful packet inspection? Can it establish VPN connections? How many simultaneous VPN tunnels can it support?

Today, home networks are used primarily to connect PCs for performing traditional tasks, such as sharing an Internet connection, exchanging files, and printing. But it won't be long before these same networks will be used to transport all types of data, including audio and video, to a wide range of gadgets throughout the home. In fact, this is already becoming a reality. With the right components, you can stream MP3s directly to your stereo and connect your gaming console to your home network.

Digital audio receivers

Adding your stereo to your home network is easy, thanks to a new type of networking device called a digital audio receiver, or DAR. A DAR sends music from your PC to your stereo using any one of a number of networking protocols: wired Ethernet, 802.11g, USB, and/or power-line networking. These vary a great deal in terms of design and features, so it's a good idea to research them all before choosing one.
Things to consider about digital audio receivers How good is its sound quality? What type of networking standard does it support? What audio outputs does it have? Does it have a TV output? What versions of Dolby Digital does it support?
Creative Sound Blaster Wireless Music

Gaming consoles

Some gaming consoles, such as the Microsoft Xbox, come with a built-in Ethernet jack, making them network ready. Not every home is cabled for Ethernet, though. Fortunately, there is an easy way around this that allows you to place your console next to your TV and hook it up to the network without stringing Ethernet cable across the room: just attach a wireless bridge or a wireless Ethernet adapter to the console, and it will play happily with the rest of your network.

Wireless presentation gateways
Presentation gateways provide a central networking node for the distribution of digital and audio content. You connect the wireless presentation gateway to a projector or a monitor, and, after doing so, anyone can connect wirelessly to the gateway to display images, slide shows, or other content on the screen. Some gateways come with internal memory and allow you to store a presentation directly onto the device so that you can leave your computer at home and take your show on the road.
