The use of One of the most interesting things about a cell phone is that it is actually a radio an extremely sophisticated radio. Mobile phones send radio waves to base stations and then the to the switch station and out to another base station or your fixed line phone. Mobile phones a one of the greatest inventions that has allowed the greater motivation within the subject of telecommunications. Cell phones provide an incredible array of functions. Mobile phone can be used to message, email and play multimedia game. Mobile phone have made it a lot safer for people in remote areas and people anywhere in general.
Although mobile phones seem innocent and like a great invention they also have their awful drawbacks. Mobile phones are similar to the radio and television systems, in that the number of frequencies available restricts the number of users within each base station. To enable a large number of users, regions are divided up into base station each with its own set of frequencies. Also antennas must be elevated and located clear of physical obstruction to ensure wide coverage and reduce them from no working. Electromagnetic radiation can be sent from such sources as radio or television transmissions, light globes and x-ray machines. The properties of electromagnetic radiation vary with wavelength or frequency.
These wavelengths just happen to be on the same as mobile phones. This therefore can interfere with the following which also use these same waves: radio communications, television, radar, microwave ovens, magnetic resonance imaging, toasters, cameras, lasers and X-ray machines. Mobile phones can have stunning health risk that many users don’t know of. After just two minutes of exposed to a mobile phones energy waves you can disable a defence mechanism in the body designed to prevent harmful proteins and toxins in the blood from entering the brain.
If these proteins enter the brain tissue there is a higher risk of brain and nerve diseases such as Alzheimer, Parkinson and multiple sclerosis. A group of independent experts led by Sir William Stewart has investigated the possible health effects posed by mobile phone technology including base stations. They said “The balance of evidence indicates that there is no general risk to the health of people living near base stations, on the basis that exposures are expected to be small fractions of guidelines.”.
