Cell phones are so convenient, what would you do without one? They let you make those important on the spot calls and important text messages during the day.
In the early 1950’s cell phones were called Radio Phones, 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. 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 has 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.
In many ways, cell phones do make our lives better and more convenient. Let’s face it, what can’t the smartphones do? Big Brother and sharing personal information just seem to be growing at a faster rate, whether we like it or not.
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 to keep an eye on your naughty apps too.
I’m on my 3rd cell phone and my first “smartphone” and I love my phone. There, I finally said it. Me, the person who always said; “Why do I need a smartphone 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 headphones while talking or anything that keeps your cell phone away from your head is the best way you can protect yourself from these problems. Don't put cell phones in your bras women!
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.
Here are some cell phone facts:
- 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.
This has been updated in 2017 and cell phones have changed even more. I now have a Samsung Galaxy s7 and I love it! Soon, I'll get an s8.
