Technically Speaking

Bluetooth.

If you use low-powerradio communications to wirelessly link phones, computers, and other network devices over short distances, it’s likely those devices use Bluetooth technology.

Bluetooth, named for a Danish king who ruled more than 1000 years ago, is a technology that primarily supports simple wireless networking of personal devices and peripherals like wireless headsets, mobile phones, and PDAs. Bluetooth devices generally communicate at speeds less than 1 Mbps and are divided into three power classes.

Class I Bluetooth devices are consideredlong-rangeunits. They have a range of up to 100 meters (328 ft.) and a maximum power output of 20 dBm.

Class II Bluetooth devices have a standard range of up to

68400-01

10 meters (32.8 ft.) and a maximum power output of 4 dBm. Class III Bluetooth devices are definitely built for shortrange communication, with a range of up to 10 centimeters

(3.9 in.) and a maximum power output of 0 dBm. Bluetooth networks feature a dynamic topology called a

piconet or PAN. These networks contain a minimum of two to a maximum of eight Bluetooth peer devices that use protocols that are part of Bluetooth standard. The current Bluetooth standard is version 2.0, and it’s actually the specification’s third version, following its 1.1 and 1.2 incarnations.

Although the Bluetooth standard uses the same 2.4-GHzrange as 802.11b and 802.11g, it’s much slower thanWi-Fi,more limited in range, and supports fewer devices.

Why Buy From Black Box? Exceptional Value. Exceptional Tech Support. Period.

Recognize any of these situations?

You wait more than 30 minutes to get through to a vendor’s tech support.

The so-called“tech” can’t help you or gives you the wrong answer.

You don’t have a purchase order number and the tech refuses to help you.

It’s 9 p. m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say

that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—andcertainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.

Don’t waste time and money—callBlack Box today.
