Cell phones are so convenient, what would you do without one? Even if it isn’t a smart phone they let you make those important on the spot calls and to die for text messages during the day. (Hey, I don’t text and drive.)
What a lot of people don’t know, and cell phone companies have been keeping from the world is that a cell phone is nothing more than a radio. It is a complex radio, but a radio none-the-less. Let’s take a look at a brief history of cell phones.
In the early 1950’s cell phones were called Radio Phones because in select urban areas, there were large, central antennas that were specifically allocated for these radio-phones. Since radio technology itself was only in the building phase, only about 25 channels were available for private use. So basically only 25 people could be talking on their radio-phones at the same time. And they only worked in cities.
It wasn’t an efficient system to say the least and a better system was needed so they came up with the cell approach.
The cell approach divided each city up into small divisions, or "cells". The technology behind cells have changed dramatically over the years, just as cell phones have, only now most standard cells are about 10 square miles large. They are usually in the shape of a hexagon. Nowadays, every individual cell has its own base station, rather than only one for an entire city.
Now modern cell phones (meaning they were created in the last 20 years or so) are made to be low-power transmitters (either 0.3 watts or 6 watts), which is much lower wattage than in past decades. This means that the same frequency can be used in the same city, at the same time, but in different cells. This is what makes our current system what it is today.
I got my first cell phone in 1998 and at the time hardly anyone had them that I knew. They were simple but they did the job with very clear reception with an antenna that you pulled up when you got a call. It had an old style (green) digital screen with no pictures or texting but it’s convenience was obvious! They were really cheap to have in 1998 but I didn’t have it for long and I wasn’t to buy another one until 2007.
In many ways cell phones do make our lives better and more convenient. Let’s face it, what can’t the smart phones do? Big Brother and sharing personal information just seems to be growing at a faster rate, whether we like it or not.
Just consider how much personal information you put on your cell. Losing it is one thing, but all the applications you put on your cell use your personal information to some extent. Next time you download an application take the time to read just what it does use on your cell to function. It usually lists this information after it tells you all the cool things the application can do for you and how you can’t live without it.
Cell phones that have internet can give you the same problems that you encounter on your home PC. Better have a virus checker on that cell, most people who have cell phones don’t think they need them. Always run a virus checker on anything that has an operating system if you want to protect your data.
I’m on my 3rd cell phone and my first “smart phone” and I love my phone. There, I finally said it. Me, the person who always said; “Why do I need a smart phone when I have an awesome computer at home?” The Android cell phones cannot be denied, I have an Evo5 4G with a 3D camera.
To top it all off now there are studies that say our cell phones are possibly carcinogenic causing brain tumors and cancer.
Just lately the World Health Organization put out a new classification for cell phones. The new classification indicates that there is some link between cancer and radiofrequency electromagnetic fields that are emitted by cell phones, but extensive study is still necessary. The panel found that the evidence that cell phone radiation was linked to one type of brain cancer was “limited” and the disassociation with any other type of cancer was “inadequate.” According to the report, the “limited” classification is just one step above the “inadequate” classification.
The problem is with the antennas or certain circuit boards in the cell phones. Holding them up to your head while you talk and exposing this directly next to your brain is what causes these tumors or serious problems. Using your head phones while talking or anything that keeps your cell phone away from your head is the best way you can protect yourself from these problems.
The panel that did this study consisted of 31 scientists pulled from 14 different countries that reviewed two large studies that found a relationship between cell phone use and Glioma, a form of brain cancer. The scientists reviewed those studies and other scientific literature for eight days at a meeting in Lyons, France.
There’s no doubt in my head that using cell phones, especially as much as we rely on them now is not a good thing for us. Just consider how many minutes you use yours a month and how you use it. You might be concerned by the answer you come up with!
Here are some cell phone facts that you are probably unaware of:
- About 20 percent of teenagers have cell phones, many of whom are girls.
- About ¼ of all Americans have cell phones, but nearly 2/3 of all Europeans do. There was also digital phone technology in Europe about 10 years before there was in the United States.
- In 1994, 16 million Americans were subscribers to a major cell phone service. Today, more than 110 million Americans currently subscribe. 1.2 billion people are estimated to be subscribers by 2010.
- There are also disposable cell phones. They are available online and only cost about $12.95.
Whatever your opinion on cell phones it’s hard to live without the convenience of having them. The fact that they are incredibly useful and fun means they will be around for a long time, until the next thing comes around to take their place.
