Bluetooth Basics – Bluetooth Technology Tutorial

Bluetooth Basics

Bluetooth technologies are not new, but people still it appears to become much more of a buzz word as opposed to a well understood, generally recognized technology. The thing is advertisements for Bluetooth enabled mobile phones, PDAs, and laptops, along with a search from the website shows a variety of different devices benefiting from this wireless standard. But, what exactly is it?


Prior to getting in to the technology, the term Bluetooth is intriguing by itself, and needs a look. The word is way less hi-tech than you may imagine, and finds its roots in European history. The King of Denmark from 940 to 981 was famous for his ability to help individuals communicate, his name (in British)… Harald Bluetooth. Possibly a little obscure, however the reference is suitable for any wireless communications standard.

Another item worth investigating may be the Bluetooth emblem. According to figures in the runic alphabet (utilized in ancient Denmark), it had been selected because it seems is the mixture of the British letter B as well as an asterisk.


The FAQ around the (https://world wide website provides a fundamental definition: “Bluetooth wireless technologies are an international specs for any small-form factor, low-cost radio solution that gives links between mobile computers, cell phones, other portable handheld devices, and connectivity to the web.”

Much like 802.11 b/g wireless networking systems and lots of cordless telephones, Bluetooth devices work on 2.4 GHz radio signals. That band appears to become obtaining a bit crowded, and interference between devices might be hard to avoid. Telephones are increasingly being offered around the 5.8 GHz band to remedy this, and Bluetooth has had its very own steps to lessen interference and improve transmission quality. Version of the Bluetooth standard greatly reduces interference issues, but requires different hardware in the original 1.0C standard, thus eliminating any possibility of backwards compatibility.

The normal specifications of Bluetooth indicate an optimum transfer rate of 723 kbps and a variety of 20-100 meters (65 to 328 ft – with respect to the type of the unit). This speed is a small fraction of that provided by 802.11 b or g wireless standards, so it’s apparent that Bluetooth does not pose a menace to replace your wireless network. Although it’s very much like 802.11 in lots of ways, Bluetooth never was supposed to have been a networking standard, but comes with many practical applications.
