Embracing the Future with Personal Area Networks
If you have a wireless network for your computers, you'll love what's next: a Personal Area Network (PAN). This setup allows all your gadgets to connect wirelessly. Simply place your Bluetooth device near your computer, and they pair automatically. Bluetooth, first introduced in 1999, continues to gain popularity due to its security, affordability, and user-friendliness.
Bluetooth Classes and Range
Bluetooth devices come in two main classes:
- Class 2: The most common, offers a 10-meter (32 feet) range.
- Class 1: Rarer, but provides a 100-meter (320 feet) range.
How Bluetooth Works
Bluetooth offers more flexibility than 802.11 wireless networking, trading off a shorter range. A Bluetooth-enabled computer uses a single receiver to connect with up to 7 nearby devices. If a device supports Bluetooth, it's usually pre-installed.
Unlike old-style wireless gadgets needing a receiver, Bluetooth devices communicate seamlessly using radio signals. Bluetooth is integrated into many computers, especially Apple Macs. For others, USB to Bluetooth adapters or internal devices are available. Laptop users can also opt for PCMCIA Bluetooth cards.
Bluetooth Applications
Bluetooth is highly popular in mobile phones and PDAs for easy synchronization of contacts and calendars. Beyond phones, devices like digital cameras, MP3 players, printers, mice, and keyboards benefit from Bluetooth. Almost any USB device can potentially use Bluetooth, acting as a wireless USB alternative.
Beyond Computers
Bluetooth’s true power lies in its ability to connect a variety of devices, not just to computers but to each other. For instance, many hands-free headsets use Bluetooth to pair with phones. Some cars now feature built-in computers that connect with Bluetooth phones for hands-free calls, even from the trunk.
Bluetooth devices can also communicate directly. A fun example is "bluejacking," where users send messages to others in close proximity. The first known bluejacking involved a playful message, "Buy Ericsson," sent between Nokia phones.
Now, bluejacking even includes sending images and serves as an emerging advertising method, called "bluecasting," which enables billboards to send messages to phones. Whether you find this innovative or intrusive is up to you.
