Where Did Those Cell Phones Come From?

In 1949 the first car phone service was introduced. It was called “Mobile Telephone Service” (MTS). But the beginning of wireless communication started many years earlier, in 1895, when an Italian physicist named Guglielmo Marconi successfully sent wireless signals a distance of one and one half miles.

In 1896 Marconi was granted the world’s first patent for a wireless telegraphy system. In 1897 he formed The Wireless Telegraph and Signal Company. During that same year he successfully sent wireless signals a distance of twelve miles.

In 1901 Marconi proved the curve of the earth did not affect the successful sending of wireless waves. He proved it by transmitting signals from Cornwall, England to St. John’s, Newfoundland, which was a distance of over two thousand miles.

Marconi, along with other scientists and researchers, continued to work and do research on wireless transmissions. In 1932 the world’s first microwave radiotelephone link was established between the Pope’s summer home in the small Italian town of Caster Gandolfo and Vatican City, a distance of approximately thirty miles.

The first ship-to-shore radio conversation took place in 1922 from the ship S.S. America, which was 400 miles at sea. Inter-continent telephone communications between the United States and England occurred in the mid 1930’s.

As technology improved, interest in a car phone service developed. The first car phone service that was introduced in 1949 was a mobile service, but the equipment was big and heavy. The phone required a large receiver (about the size of a large piece of luggage). It was placed in the trunk of the vehicle. To talk on the phone, a button had to be pushed. To listen to the other person, the button had to be released. It was similar to using a two-way radio. A person couldn’t talk and listen at the same time. That technology came later.

All You Ever Wanted To Know About Cell Phone Batteries

Cell  phones run on various kinds of batteries depending on the manufacturer, phone size or shape and features. There are basically four types of cell phone batteries: Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.

Lithium Polymer is the most recent type and applies the latest technology in DC power. This type of battery is light in weight and will not explode even if pierced. The battery elements are enclosed in platic pouches and do not have memory defects. They last about 50 times longer than Nickel Metal Hydride batteries.

Lithium Ion is also memory efficient and longer lasting than Nickel Metal Hydride batteries but they are quite lighter. They tend to be expensive and would only fit new models of phones. Most Lithium-ion batteries apply a fast charge technique to quickly charge up your cell phone up to 80% capacity and then slowly bring it up to full power in about two hours.

Nickel Metal Hydride is also memory efficient and lasts longer than the NIM type about 40 times. This type of battery is good for people who need rapid charging and if used with a car charger can be fully charged under 1 hour. The special formula permits the concentration of energy in a single pack – sometimes about twice the power of Nickel Cadmium. This type is preferred by a lot of mobile phone users because it lasts long and is cheap. Again, they are non-toxic and appeals to environmentalists.

Nickel Cadmium are the oldest type and has a lot of memory defects. Another severe disadvantage is that they will have to be totally discharged before you can charge them again otherwise you may irreversibly damage them. Again this type is highly toxic due to the presence of Nickel Cadmium and is gradually being phased out by cell phone manufacturers.

2. What is a Dual Band Phone?
A Dual band phone is a phone that can operate on an analog and digital service.

3. What type of battery has the longest life?
Lithium-Ion or Li-Ion batteries have the longest life. They also happen to be the lightest in weight. The two pluses means there is minus attached, which is price. A li-ion battery will always be the most expensive type of battery available.

4. What's the difference between the Stand-by time and Talk time?
Your phone is in standby mode when your phone is on but you aren't talking. The power consumption is minimal and the phone can stay in this mode for a longer period of time. When you are using the phone you are using talk time. This consumes battery power at a much quicker rate. Your battery life will be somewhere between talk time and standby time

5. What is a roaming charge?
A roaming charge is when you make a call from outside of your calling area. Your calling area is defined by plan local, regional or national.

Top 9 Used Car Salesman Tricks, and How to Avoid Them

One of the biggest moments in many people’s lives is driving off in their brand-spanking-new automobile. It’s an exhilarating feeling. It’s also a big moment because in that very instant, that brand-spanking-new car loses a big chunk of its value—the difference between the retail price you paid and the car’s wholesale value. That’s typically thousands gone in an instant.

That’s why some car buyers choose to shop around for a used car. You save yourself that steep initial drop-off in value. More importantly, you get a car that runs just as well, is just as dependable, and looks and feels as good as that new car—that is, if you play your cards right.

For if there is one pitfall of buying a used car, it’s the risk of buying a lemon, a junker—call it what you want, you get the point: the wrong car. Used car dealers, after all, have nearly as bad a reputation, if not worse, than lawyers do. This holds true for individual people selling their cars through newspapers, Web auctions and classified sites, or with the old-fashioned signs in their car windows. The saying, “Buyer Beware,” no where has more meaning than with cars.

The opposite to that, of course, is that there are some real steals out there in used cars. We’re talking about quality vehicles that will perform beyond your expectations at a low price. Here’s how to find these perfect used vehicles, and avoid the top 10 scams that used car dealers everywhere try to pull on you.

1. Get a second opinion for the hype. Used car dealers will bombard you with every adjective under the book to sell you on a car—sporty, thrifty, fast, and etc. Don’t take their word for it. Instead, find someone you know, whether a neighbor, a colleague, a family member, or a friend, who owns the same make and model of the vehicle, and ask them for their opinion.

5 Steps To Buying Your Car

Most people do not enjoy buying a car. A survey conducted by CNN revealed that 75% of people would rather visit a dentist than face visiting a car dealership. It's not that people don't want a car - it's just that there are so many pitfalls to negotiate and not everyone can be sure of the right steps to take. Here are a few points to keep in mind to make the process easier.

1. Ask questions, lots of questions. Try to ask sensible questions that will enable you to base your decisions on solid ground. But don't be afraid to just ask and only stop when all your concerns have been properly addressed.

2. Do not let emotion drive you. Pretty cars with all the bells and whistles can blind you to the truth. More often than not you will end up paying more than you need to if you buy with emotion. Be impartial and see the car for what it is and not what you may have fallen in love with.

3. Know exactly what you want before you put a single foot inside the dealership door. An open mind can be easily manipulated, and usually not in your favor. Use brochures, etc, beforehand to determine exactly what you want within your budget, and don't be swayed by smooth talk.

4. Talk to the dealer about the price and not the payments. Dealers who keep referring to the "easy" payments could be avoiding the issue of overall price, and you need to know why. Do your homework and you will know exactly what price fits into a payment plan to fit your budget. But if you focus on payment, you may end up paying more than you bargained for.

Understanding Low Carb Diets

With all of the conflicting studies and fuzzy interpretation of information, it's no wonder that confusion reigns when it comes to the value and safety of low-carb diets. It seems like heated debates are raging everywhere!

Whether it's Atkins, the South Beach or some other low-carb plan, as many as 30 million Americans are following a low-carb diet.

Advocates contend that the high amount of carbohydrates in our diet has led to increasing problems with obesity, diabetes, and other health problems. Critics, on the other hand, attribute obesity and related health problems to over-consumption of calories from any source, and lack of physical activity. Critics also express concern that the lack of grains, fruits, and vegetables in low-carbohydrate diets may lead to deficiencies of some key nutrients, including fiber, vitamin C, folic acid, and several minerals.

Any diet, weather low or high in carbohydrate, can produce significant weight loss during the initial stages of the diet. But remember, the key to successful dieting is in being able to lose the weight permanently. Put another way, what does the scale show a year after going off the diet?

Let's see if we can debunk some of the mystery about low-carb diets. Below, is a listing of some relevant points taken from recent studies and scientific literature. Please note there may be insufficient information available to answer all questions.

- Differences Between Low-Carb Diets

There are many popular diets designed to lower carbohydrate consumption. Reducing total carbohydrate in the diet means that protein and fat will represent a proportionately greater amount of the total caloric intake.

Atkins and Protein Power diets restrict carbohydrate to a point where the body becomes ketogenic. Other low-carb diets like the Zone and Life Without Bread are less restrictive. Some, like Sugar Busters claim to eliminate only sugars and foods that elevate blood sugar levels excessively.
