Bluetooth Basics

Bluetooth technology is nothing new, but in many respects it still seems to be more of a buzz word rather than a well understood, commonly accepted technology. You see advertisements for Bluetooth enabled cell phones, PDAs, and laptops, and a search of the Geeks.com website shows all sorts of different devices taking advantage of this wireless standard. But, what is it?

History

Before getting into the technology, the word Bluetooth is intriguing all on its own, and deserves a look. The term is far less high tech than you might imagine, and finds its roots in european history. The King of Denmark from 940 to 981 was renowned for his ability to help people communicate, his name (in English)... Harald Bluetooth. Perhaps a bit obscure, but the reference is appropriate for a wireless communications standard.

Another item worth investigating is the Bluetooth logo. Based on characters from the runic alphabet (used in ancient Denmark), it was chosen as it appears to be the combination of the English letter B and an asterisk.

Capabilities

The FAQ on the Bluetooth.org (https://www.bluetooth.org/) website offers a basic definition: "Bluetooth wireless technology is a worldwide specification for a small-form factor, low-cost radio solution that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet."

Just like 802.11 b/g wireless networking systems and many cordless telephones, Bluetooth devices operate on 2.4 GHz radio signals. That band seems to be getting a bit crowded, and interference between devices may be difficult to avoid. Telephones are now being offered on the 5.8 GHz band to help remedy this, and Bluetooth has taken its own steps to reduce interference and improve transmission quality. Version 1.1 of the Bluetooth standard greatly reduces interference issues, but requires completely different hardware from the original 1.0C standard, thus eliminating any chance of backwards compatibility.

The typical specifications of Bluetooth indicate a maximum transfer rate of 723 kbps and a range of 20-100 meters (65 to 328 feet - depending on the class of the device). This speed is a fraction of that offered by 802.11 b or g wireless standards, so it is obvious that Bluetooth doesnt pose a threat to replace your wireless network. Although it is very similar to 802.11 in many ways, Bluetooth was never intended to be a networking standard, but does have many practical applications.

practical Applications

There are a variety of products that take advantage of Bluetooths capabilities, from laptops and PDAs, to headphones and input devices, and even wireless printer adapters.

Many Laptops include an onboard Bluetooth adaptor to allow the system to connect to any Bluetooth device right out of the box. For laptop or desktop systems that do not have an adaptor built in, there are many usb Bluetooth adaptors available.

Bluetooth enabled PDAs allow for convenient wireless synchronization and data transfer.

headphones can take advantage of Bluetooth for two purposes audio playback and mobile phone communications. Using something a mobile headset with a Bluetooth enabled mobile phone allows anyone to go hands free, as well as wire free.

Logitech, and other manufacturers, also produce input devices that eliminate wires thanks to Bluetooth. You can add a Bluetooth mouse to your system, or both a mouse and keyboard. One advantage that Bluetooth wireless keyboard/mouse combinations have over the standard RF wireless keyboard/mouse combinations is range. Where most standard RF keyboard/mouse combinations have a range up to 6 feet; a Bluetooth keyboard/mouse combination will usually have a range of up to 30 feet.

Bluetooth printer adaptors make sharing a printer extremely convenient by eliminating the need for any wires or special configurations on a typical network. Printing to any compatible HP printer from a PC, PDA or mobile phone can now be done easily from anywhere in the office.

Final Words

At this point the popularity of Bluetooth might not be as large as some proponents would have hoped, but many devices are available for those interested. The cost and competition from other standards have hindered the widespread acceptance, but Bluetooth does offer a viable solution to many devices that might not have wireless connectivity without it.

Computer Geeks tech tips and computer advice

Do you do Bad Things? Even though you know you shouldn't?

It's not your fault. It really isn't. You know you should stop doing it, but no matter how much you know that, and how much you try, you just can't stop!

Everyone knows how to lose weight. Don't eat fattening foods. exercise. Everyone knows how to give up smoking. Dont light the cigarette. Yet having this knowledge just isn't enough. Sometimes even having the desire isn't enough! Time and again I hear about people who get really close to quitting smoking. They can get all the way down to one or two cigarettes a day, but just can't give up those last two. Many even make it all the way down to zero, but the cravings, oh the cravings! They are wretched, those cravings. Most will go back to smoking within the first few days. They can cut away most of the "stuff" that keeps them glued to the cigarettes, even not be addicted to nicotine anymore(!), but there is just something deep in their core that magnetically pulls them back in, like two lovers who know they are bad for each other but just can't help themselves.

What is this thing? What is at this core?

Let me take a step back for a moment. How many adults do you know who are happy? I mean really, truly happy? Think that question is foolishness? Let me ask you this. How many people do you know who love their work? I'm talkin' jump out of bed in the morning, can't wait to start. Sadly, the percentage is very small. Why is this?

We live in an interesting quick-fix culture. People don't really have to deal with their issues. We've got:

* television
* movies
* shopping
* toys
* and hitting the gym

to distract us and make us feel better. Even more than that, many people's issues are quite buried. Think of dreams that were squashed when we were young. "An artist? You could never make a living at that! You should be a doctor!" People often forget what their dreams once were.

As a result, I see an awful lot of unhappy, unfulfilled people walking around. They don't know what is bothering them, they just have that gnawing feeling that there must be more. Advertisers pray on this, selling us more and more bottles and gizmos to give us that ever elusive Happiness.

True inner needs? People either:

* think they're impossible to fulfill
* are too scared and resigned to fulfill them
* or are so disassociated from those needs that they don't even know what they would be even if they had to guess!

All those "bad" things -- smoking, overeating, gambling, alcohol, the list goes on and on -- are easy ways to fill the void. Smokers will be able to relate to this one -- if you've just had a fight with your family, what do you do? You go for a smoke. Smoking makes it feel like the problem goes away. (I call this the "smokescreen." Har har!)

I'll let you in on a little secret--the real reason it's so hard to quit is not the nicotine. It's this void-filling. When you quit smoking (or any bad habit), you're suddenly faced with real life. All those stresses and needs that you've been avoiding? There they are, pulling at your coat tails, yelling, "Pay attention to me! Pay attention to me!" If you got in touch with your real inner needs and took baby steps to start fulfilling them, you would actually have little desire for cigarettes. It's true! I see it happen time and again in my Stop Smoking Coaching practice.

How do you do that, you ask? Here are some baby steps that you can start trying out now:

* Next time, instead of taking that quick fix--stop.
* Have a little quiet time and listen to what your insides have been trying to tell you.
* Try journaling -- don't edit your thoughts, just write.
* Some people find meditation and yoga to be great accesses.
* Try deep breathing.
* Go for a quiet, leisurely walk by yourself.
* Personally, I find it easiest to just start noticing where in life I seem to be avoiding things the most, or if I want something more immediate and active, doing a mindmap (a word drawing) to figure out what I'm really thinking.

For each person, the key to figuring out your needs is different. play around with it, don't give up! You'll be glad you did!
