The amazing technology of Bluetooth presents a great way of exchanging data between two wireless devices. Unlike telephones, there are no wires or messy leads to worry about.  You can enjoy wireless communications with short distances of up to thirty feet.

Bluetooth also offers interoperability, meaning that you can use your portable Bluetooth device to connect with existing Bluetooth points.  This way, you won’t have to carry a data lead or CDs of drivers around with you everywhere you go.  You can enjoy the best of wireless without having to worry about installing your software.

With today’s Bluetooth, you can use your PDA and cell phone to surf the net or check emails as you travel. If you are in the business field, this can be very beneficial, especially if you like to check your email throughout the day.  Bluetooth will enable you to check your email no matter where you are – which is great news for those who like to travel.

Bluetooth will also enable to you to transfer files as well, such as MP3 and photo to and from your mobile device. Bluetooth dominates the world of short range wireless, enabling you to do more than you may have thought possible.

One of the best things to Bluetooth and something everyone loves is the wireless headset.  Bluetooth offers wire free headsets for your cell phone or computer, which is great for those who like to walk around or talk on the phone in the car, without  having to worry about your hands getting in the way.

To make things even better, you can use a Bluetooth GPS device for satellite navigation on your PDA, laptop, or mobile.  If you travel – this can be really great to have.

Bluetooth is a high speed, low powered wireless link technology that’s designed to connect phones or other portable equipment together with little to no work required by the user.  Unlike infrared, Bluetooth doesn’t require line of site positioning to work.

Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed.

When one Bluetooth device comes in contact with another, they will automatically exchange addresses and details of capability.  Then, they can establish a 1 MB link with security that they will use as required.  The protocols involved with handle both data and voice, with a very flexible topography.

The technology achieves its goal by embedding tiny, non expensive short range tranceivers into the devices available today.  The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels.

Each devices offers a unique 48 bit address from the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power.  The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.

What’s important, is the fact that Bluetooth devices won’t drain battery life.  The specification targets power consumption of the device, limiting the drain on the battery.  The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.

Bluetooth will also guarantee security at the bit level.  The authentification is controlled by the user via a 128 bit key.  The radio signals can be coded with anything up to 128 bit.  With the frequency hopping, Bluetooth is already very
hard to listen into.

The baseband protocol is a combination of both circuit and packet switches.  Slots can be reserved for synchronous packets as well.  Each packet will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.

Bluetooth can also support data channels of up to three simultaneous voice channels.  Therefore, it’s possible to transfer the data while you talk at the same time.  Each individual voice channel will support 64 KB.

From a technical standpoint, Bluetooth is very different indeed.  It’s the best wireless method in the world, surpassing even infrared.  For communication on the go, Bluetooth is indeed very hard to compete with.

Bluetooth has a lot to offer with an increasingly difficult market place.  Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN (Local Area Network).

In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is infrared.  Infrared holds many key features, although the line of sight it provides doesn’t go through walls or through obstacles like that of the Bluetooth technology.

Unlike infrared, Bluetooth isn’t a line of sight and it provides ranges of up to 100 meters.  Bluetooth is also low power and low processing with an overhead protocol.  What this means, is that it’s ideal for integration into small battery powered devices.  To put it short, the applications with Bluetooth are virtually endless.

Disadvantages
Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition.  The only real downsides are the data rate and security.  Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.

For this very reason, infrared has yet to be dispensed with completely and is considered by many to be the complimentary technology to that of Bluetooth.  Infrared has inherent security due to its line of sight.

The greater range and radio frequency (RF) of  Bluetooth make it much more open to interception and attack.  For this reason, security is a very key aspect to the Bluetooth specification.

Although there are very few disadvantages, Bluetooth still remains the best for short range wireless technology.  Those who have tried it love it, and they know for a fact that Bluetooth will be around for years to come.

Below, are 10 benefits and reasons to use Bluetooth
technology.

1. Wireless
As you probably already know, there are many benefits and advantages to using wireless devices. Along with improving safety as a result of eliminating wires you don’t need, wireless also offers you plenty of other advantages. When traveling with your laptop or other wireless devices, you’ll no longer have to worry about bringing connection cables.

2. Bluetooth is actually inexpensive

The technology of Bluetooth is cheap for companies to implement, which results in lower costs for the company. These savings are then passed from the company on to you.

3. Bluetooth is automatic
Bluetooth doesn’t have you set up a connection or push any buttons. When two or more devices enter a range of up to 30 feet of each other, they will automatically begin to communicate without you having to do anything.

4. Standardized protocol
Bluetooth is standardized wireless, meaning that a high level of compatibility among devices is guaranteed. Bluetooth will connect devices to each other, even if they aren’t the same model.

5. Low interference
Bluetooth devices almost always avoid interference from other wireless devices. Bluetooth uses a technique known as frequency hopping, and also low power wireless signals.

6. Low energy consumption
As a result of Bluetooth using low power signals,
the technology requires very little energy and will use less battery or electrical power as a result. This is an excellent benefit for mobile devices, as Bluetooth won’t drain the battery.

7. Sharing voice and data The standard for Bluetooth will allow compatible devices to share data and voice communications. This is great for mobile phones and headsets, as Bluetooth simplifies driving and talking on your cell phone.

8. Instant PAN (Personal Area Network)
You can connect up to seven Bluetooth devices to each other within a range of up to 30 feet, forming a piconet or PAN. For a single room, you can also set up multiple piconets.

9. Upgradeable
Upgradeable is the standard for Bluetooth. There are newer versions of Bluetooth in the works, which offer many new advantages and backward compatible with older versions.

10. The technology stays
Bluetooth technology is a world wide, universal wireless standard. With it being as popular as it is, you can count on it being around for years to come. As more and more devices start to use Bluetooth technology, more manufacturers will be eager to make their products compatible. A chain reaction will occur, making Bluetooth the standard for cutting edge wireless.

Is it really possible to run a free reverse cell phone lookup on the internet? Many of us have become disillusioned and frustrated in the past with websites which appear to offer free products or services online but in fact do not. Is this the case with cell phone lookups?

Firstly let us examine exactly what we mean by a phone number lookup. If you have in your possession a residential phone number but no idea who the number belongs to or what address it relates to you can use a “reverse lookup” service to find out those details. This can obviously be very useful in situations where you have lost contact with someone but still have a record of their phone number, or simply wish to verify who owns the number before mistakenly phoning the wrong number. There are many places you can perform such residential and business phone lookups online for free, including toll-free numbers.

However a problem arises when you need to run a reverse lookup on a cellular phone as the free directories do not contain any such numbers. Similarly they do not contain fax numbers as this information is only held by the carriers and telecommunications companies. Do these records exist, and are they free?

The good news is there are websites which claim to offer large numbers of cell phone numbers, but they are not free. These websites naturally have to pay for access to some of this information, and go to the considerable trouble of pulling all the various resources together in one place, and as a result you will be charged a small fee before you can access the lookup databases. However the fee is a one-off payment and with some websites you can run as many searches as you like once you have access, with others they offer a single lookup for a lower fee. The records they claim to offer include cell owner details, address history, carrier details, and the phone connection status. It is also worth noting that the databases offered by each company differ to some degree, but most include cell phones and often residential, business, toll-free, even pagers, and these websites say your searches are guaranteed legal and confidential.

In addition to reverse lookups there are also similar websites which offer access to information such as background checks and background reports, people finder databases, bankruptcies, liens, public records databases including births, deaths, marriages, divorces and adoptions, sex offender records, police records, and much more. These sites operate in the same way, offering access to specific types of information for a set fee, however it should be noted that you will not receive access to such information as part of your cell phone lookup site membership.

I have seen websites claiming to offer free cell lookups, but they always lead eventually to the paid sites in the end, even allowing people to search for free and then charging to view the results. It is the sad truth that the only place where you are likely to find detailed reverse cell records is within the legitimate paid directories. In conclusion, the answer is no, free cell phone lookups do not currently exist. However if you really want to access such records then I believe paying a small fee is a price worth paying.

For more information including a list of popular reverse cell phone lookup sites visit Cell-Phone-Pages.com. Cell Phone Pages also contains hundreds of cell phone and telecommunications articles and resources covering all aspects of cell phone safety, security, accessories and shopping.

The use of traditional telephone services (POTS) are declining. The use of cell phoens and VOIP has increased significantly.

With the decreased use of traditional phone lines, local, state and federal governments are taking a hit to the pcket book as well.

Without the tax revenue generated from these traditional phone lines, governments have to seek their revenue elsewhere.

Cell phone users are being hit at a cyclic rate with additional taxation by government to compensate for the lost revenue from traditional phone services.

According to USAToday,
“The new charges are adding $2 to $10 or more a month to cell phone bills on top of existing federal and state taxes and fees for emergency 911 communications.”

So what does this mean to you?

Let us know here on our blog.

Trying to find out what is new in the cell phone regulatory world today, I plugged “cell phone legislation” into a couple of search engines.

I noticed that there where several listings focused solely on states and not federal government.

Now for those that like less government control in our lives this should be a relief that they are leaving it to the states to control this.

Wireless laptops in cars while driving perhaps?

I am sure some of you have seen the following e-mail and it goes something like this:

Subject: Here is something worth knowing if you have a mobile phone

Have you ever wondered why phone companies don’t seem interested in trying to prevent the theft of mobile phones? If you have ever lost, or had one stolen, andif you are on a plan, you still have to pay the plan approximately up to 24 months, and you have to buy another handset and enter into another
contract. This is more revenue for the phone company.

There is a simple way of making lost or stolen mobiles useless to
thieves and the phone companies know about it, but keep it quiet.

To check your mobile phone’s serial number, key in the following on your phone:

star-hash-zero-six-hash ( * # 0 6 # ) and a fifteen digit code will appear on the screen. This is unique to your handset.

Write it down and keep it safe. Should your mobile phone get stolen, you can phone your service provider and give them this code. They will then be able to block your handset, so even if the thief changes the sim card, your phone will be totally useless. You probably won’t get your phone back, but at least you know that whoever stole it can’t use/sell it either. If everybody did this, there would be no point in stealing mobile phones. You may want to send this to as many people with mobiles as possible. No charge for directory assistance. Phone companies are charging us $1.00 or more for 411- information calls when they don’t have to.When you need to use the 411 / information option!, simply dial 1-800-FREE-411 or 1 800 373 3411 without incurring a charge.Works on home phones and cellphones.

Well, this is somewhat false. As I stated before in another post about cell phone myths, please visit snopes.com.

You will ifnd this particular myth at Snopes.

The results are in. I tallied a some associates of mine about how they use cell phones in their personal and business life.

The results surprised me. Most use the cell phone for the basic features that it offers.

Below are some of the quotes:

” I’m a total junky. I just picked up a Motorola Q , I can surf the net, email, pictures, video, microsoft word, excel, PowerPoint and PDF Files contact management, calendar, windows media, MP3 player, Bluetooth, connect my laptop to the net, pc synchronization, and about 100 other things I haven’t figured out yet.
Oh yeah, i’m pretty sure I can make phone calls with it too “

“I use my cell for emergencies, basically. It takes pictures and such, but I’m not big on that stuff. It’s a phone.
When I got my first one back in ‘98, my daughter was little and I wanted to be available when she was at school, in case she got sick or whatever. Now, we use it to locate one another in the mall. LOL
I like being available for some clients whenever they need me, but nobody ever does.”

“Like Pat, mine is basically for emergencies. I purchased one only after a friend of mine was in a car accident and ended up at the bottom of a ditch in the middle of a Michigan winter in a snowstorm. Had she not had her cell phone to call for help, she would have died there within the hour.
It would have come in very useful when our vehicle stalled in the fast lane on an extremely busy 6 lane highway in Georgia as well! Thankfully, a gentleman behind us had a cell phone and was able to call for emergency help. ”

“I’m a junkie.
While I’ve yet to figure out all the functions of my cell phone I use it exclusively for business. I only keep it in my office when I’m at home, so if i’m watching a movie or spending time with my son ….I let voice mail get it. If I leave home, the cell goes with me. “
Jennifer Herold
TDH Central

That is just a few of the comments I received when I asked them if they were a cell phone junkie. I was very surpirsed as to the results from the folks who own their own business. I can honestly say it seems most use their cell phones just like everyone else.

How does everyone else use their cell phone?

Well, like a phone silly. How else?
