Do You Need Bluetooth?

When buying any digital electronic device, whether a cellphone, PDA, or notebook computer, it is important to check the specifications to ensure that it will serve your purposes. bluetooth is becoming an increasingly popular offering in personal electronics, but do you need it?

What Is Bluetooth?

Bluetooth is a wireless PAN (Personal Area Network) transmission protocol standard. In laymans terms, Bluetooth is a technology that enables a device to communicate and share data with other bluetooth capable devices cellphones, headsets, PDAs, notebook computers, desktop PCs, computer peripherals, printers, cameras, and others through radio wave transmission (so there is no need for wires) at a range of around 1, 10, or 100 meters, depending on the class of your bluetooth device (Class 1 has the longest range and Class 3 the shortest).

If a device has a bluetooth chip, it can communicate with other devices that have a bluetooth chip. Users can share pictures, movies, datasheets, documents, and all sorts of information among them as long as their devices are in range (they do not need to be in direct line of sight). For instance, a bluetooth-capable digital camera can communicate with a bluetooth-capable printer for direct printing. Likewise, a bluetooth-capable cellphone can be connected to a bluetooth-equipped headset so that a person can take and make hands-free telephone calls.

bluetooth can be used for internet connectivity as long as a bluetooth-enabled computer is in range of a bluetooth modem. bluetooth devices can also form a small wireless network (called a piconet) of up to 8 devices. For security, devices can be paired and transmissions encrypted. So that it causes only minimal interference, bluetooth periodically changes frequency channels.

bluetooth uses the same radio frequency that 802.11 Wireless Networking does, but it is much simpler than 802.11 technology, negating the need for complex network configurations. bluetooth also has lower power consumption, making it more economical, though its range is shorter.

You Need bluetooth

If you wish to have an extremely basic home network, bluetooth is for you. There are no wires to trip you and there are no complex configurations like network permissions or addresses to deal with. Piconets are temporary, so a new device can immediately join or leave a bluetooth network with nothing more than a simple device discovery. It is important to note, however, that piconets are no substitution for a traditional home network (whether through Ethernet or 802.11 Wireless), which are much more reliable and offer much more full-bodied security options.

If you have a notebook computer, there is a good chance you will want to have bluetooth connectivity so that you can take advantage of the many bluetooth-equipped peripherals, thereby eliminating the need for bulky wires. You can also easily synchronize data between your handheld devices and your notebook computer. Moreover, if you are fond of sharing data with other handheld device users, you definitely need to have bluetooth for easy and convenient data sharing.

You Dont Need bluetooth

It is important to note that bluetooth can present a security risk if you store sensitive information on your bluetooth-enabled device. If you are traveling with sensitive information on your computer, cell-phone, or PDA, it is wise to disable bluetooth temporarily to prevent data theft or exploitation. Please also note that some corporations and government entities disapprove of bluetooth and similar convenience-based additions, so please check with your employer if you intend to use your bluetooth-enabled notebook for business.

The Perfect Golf Swing

It has been estimated that there are some 50 million golfers worldwide and that 80% of all golfers will never achieve a handicap of less than 18. Also, despite the advances that have been made with golf instruction videos, books and equipment, the golf handicap of players has not improved over the last 20 years. What, then, is the problem?

Most golf players experience the ups and downs of the game. One minute they think they have found the perfect golf swing, for example, as they could do little wrong in their last game. The very next game they are lamenting about they just couldnt do anything right and had a disastrous result. They then go onto that continuous merry-go-round, it seems, of searching for the perfect golf swing.

I too have been one of those golfers searching for the perfect golf swing. I have hacked my way through a game on many occasions, vowing countless times that I would never play this frustrating game again. I have practiced non-stop for hours on end. I have searched and searched for that secret bit of instruction that would turn my game around dramatically, but without success until now!

I have been introduced to an amateur golfer who has shared my frustrations and who, after a 4-year search, has found the perfect golf swing. He has discovered that once he understood just what the golf professionals were doing to execute a consistent and repeatable swing, he was able to introduce this discovery into his own game with unbelievable results. Other players, of course, are also benefiting from his discovery.

I was skeptical at first as I had tried various bits of golf instruction over the years, without notable success. The very first game I played after reading my friends instruction, though, changed my mind. On my best days I play to a 17 handicap. On my worst days well, lets just say I struggle. My first game yesterday after my enlightened instruction, though, was inspiring.

Of the 9 holes I played, here are my results:

1) Hit the par 3 green with my straight-as-a-die tee-shot and looking at a possible birdie. Settled for par.
2) A great drive and a great second shot to hit the par 4 green in regulation. Settled for par.
3) Because I was hitting the ball so well, I decided to step well back of the tee in case I over-hit the short par 3 green. Big mistake as my straight shot was just short of the green. Settled for a one-over.
4) My tee shot to the long par 3 was just slightly right of the green. Settled for a one-over.
5) Two great shots saw me on the par 4 green in regulation. Par.
6) Hit two great shots into a strong head-wind, so disappointed to have not made the green on the courses longest par 4. It must have affected me because I played the only bad shot of the day, a fluffed chip onto the green. Three putted for a two-over.
7) Three great shots to the edge of the par 5. One over.
8) A good drive, but a bit left. A great recovery shot just to the edge of the par 4 green. One over.
9) My best drive of the day, leaving an 8 iron shot to the par 4 green. Just missed a birdie. Par.

I had just played the most enjoyable 9 holes I have played for quite some time. Now that I understand just what the pros are doing to execute a repeatable swing and incorporating that information into my own game, I am getting results. I am confident on continuing on this path of improvement. I have found the perfect golf swing.
