Cell phones are undersized hand-held phone like devices with built-in antennas. They are frequently called cellular, wireless, mobile, or PCS phones. Cell phones are all the rage with people, particularly those who are frequently on the go, given that they can be carried easily.
Basically, cell phones are two-way radios. When you speak into a wireless phone, it picks up your voice and converts the sound to radio frequency energy or radio waves. The rf waves then travel through the atmosphere until they reach a receiver at a nearby base station. From here, it is the base station that sends your call through the phone network until it reaches the individual you are calling.
Health Concerns over Cellular Phones
The most current issue about cell phones is their supposed health hazards. As declared earlier, cell phones are radios. On the other hand, to be more accurate, cell phones are low-power, single-channel, two-way broadcasting devices. When you speak on your cell phone, you are in fact talking to a nearby base station. Cell phone base stations are low-power, multi-channel, two-way radios. Their purpose is to send your phone call into the conventional land-line phone system so you can start talking with the individual you are calling.
Now, as cell phones and their base stations are two-way radios, they generate radio-frequency (RF) energy which is what they use for communication. The people who are in close proximity to them are of course exposed to the RF energy. Nonetheless, because both the cell phones and the base stations are low power, meaning they only display short range energies, the RF energy exposure levels from them are generally very low.
The scientific community both in the United States and globally agree that the power from these cell phone base station antennas is far too low to produce health hazards and as long as people keep away from direct access to the antennas, they are safe from any supposed health risks.
Cell Phones – Buying and Savings Tips
Cell phones are the “in” thing these days and it’s difficult not to find anyone without one. However, in spite of cell phones being an absolute must, there’s no need for you to pay much for a device that you barely even use. So, if you don’t use cell phones very often, select a low conversation service plan for your mobile. Many areas offer cell phones for as low as $19.99. This allows you the handiness of mobile phones but without making too much of a dent on your wallet.
Another outstanding tactic to save on your cell phones is to only get features you require. Call your wireless provider to stop extra features if you are not using them. This will permit you to save some on your cell phone service plan.
