Are mobiles dangerous?

There is controversy and debate about whether mobile phones are safe. The Stewart Report was commissioned in 1999 to look into health effects of mobile phones and found that the balance of evidence of that time did not indicate adverse health effects.

Long term health damage may take many years to show up. Cancers typically take between 15 and 30 years to manifest but the carcinogen may start causing damage immediately.

Since the Stewart report, many studies have been published. All the independent studies show an association with brain tumours. Other studies indicate mobile phones may increase other cancer risks and damage fertility.

The Department of Health advises that children under 16 should only use mobiles for short essential calls.

How do you fix a virus on your cell phone?

Answer for mobile phone virusWell its plain and simple take your phone to the service provider and tell them to fix it!

--->yeah, well, that's what i would do if i was stupid enough to not even be able to fix my own darn phone.

here's what you should do, try to secure a copy of a PC studio software (the CD that came in with the phone upon purchase) for your PC. install it. from here on, you should be able to access your phone freely on your desktop computer. then scan your phone using your desktop computer antivirus, and that should do the trick.

instead of doing what Mr. Genius here is suggesting and waste a lot of money, try that as some kind of first-aid. if it doesnt work, then just post here again, I'll give you a few more steps.

How do you find out the carrier of a cell phone?

Carrier and Cell Numbers That BC area code is the same for all cellular users. In Bc and Canada the numbers will still be different as the number is owned by the company not the person using it. Come march of next year they will be introducing what is called phone number portability in which case customers will be able to take their phone number with them to any carrier they choose.

In BC I know that the area code 778 is usually FIDO. celluar carriers are given blocks of numbers within a certain range. Is there any way to find these blocks of numbers?

Try the free website called fonefinder.

How did cell phones have a bad affect on society?

Cell phones are integral to modern societies because of their usefulness in transmitting the information upon which post Industrialized societies depend. However, this technological leap forward is not without repercussions. Teachers are having increasing difficultly maintaining their student's focus in class. This is due in part by the increase in both cell phone ownership amongst younger individuals as well as the increasing sophistication of the devices they own. Safe to say, one could easily understand why a young adult, bored in his or her last class of the day would rather turn to tetris than spend another hour repeatedly solving Linear inequalities or texting their friends instead of reading Oedipus Rex. Tweeting could bring about a radical shift towards narcissism but that's an opinion of mine not a fact. There are other consequences and others are sure to arise in time but a problem developed nations are dealing with today is the issue of teens ignoring their studies during school to play with cell phones.

What are four types of communication?

AnswerWire, fiber-optic, or wireless (IR or RF).

-DJ Craig

AnswerMedia used for communications:
  • recorded media (books, newspapers, CD ROMS, memory sticks, etc) physically delivered from transmitter to receiver and decoded visually, mechanically, magnetically or electronically;
  • air and other fluids (sound or pressure waves, light, IR, RF, often modulated)
  • solids (mechanical motion or vibration, electrical signals, magnetic tapes and disks, visible light in glass)
  • vacuum (RF, visible light)
Answer">Answer">Answer">Answercommunication media (transmission media)are of two types:-

guided and unguided

guided communication media includes :-Twisted pair ,fiber optic ,coaxial cabel

unguided media includes: antenna ,Broad cast radio

Answer

Communication media (also called transmission media or communication channels) may be wired or wireless.

Wired media include copper cables (e.g., twisted-pair copper wire cable - the "telephone cable", coaxial cable, UTP cable - the "LAN cable", etc.) and optical fiber cables (made of glass or plastic). Copper cables allow the propagation of electric signals (i.e., electric voltage or current pulses), whereas optical fiber cables allow the propagation of light pulses.

Wireless media include the free space, the ionsphere, etc. Wireless media allow the propagation of electromagnetic waves. The transmission/reception of electromagnetic waves requires the use of some wireless link(also called radio link, due to the fact that radio broadcast was one the first commercial wireless communication system in use), such as terrestrial microwave links, satellite links, etc.

Other types of channels include storage media (e.g., hard disks, cd, dvd, etc.) and underwater acoustic channels(which allow the propagation of sound waves).

Communication channels vary in capacity (i.e., the amount of information per time unit that can be carried in a reliable fashion), attenuation (i.e., reducing of transmitted signal's strength; attenuation increases with the channel length), distortion (i.e., alternation of signal's variation pattern, where is impressed the information), noise (i.e., random unwanted signals that corrupt the signal shape), etc.

What country invented the phone?

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first portable handset and the first person to make a call on a portable cell phone in April 1973. The first call he made was to his rival, Joel Engel, Bell Labs head of research. AT&T's research arm, Bell Laboratories, introduced the idea of cellular communications in 1947. But Motorola and Bell Labs in the sixties and early seventies were in a race to incorporate the technology into portable devices. Cooper, now 70, wanted people to be able to carry their phones with them anywhere. While he was a project manager at Motorola in 1973, Cooper set up a base station in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public. In 1973, when the company installed the base station to handle the first public demonstration of a phone call over the cellular network, Motorola was trying to persuade the Federal Communications Commission to allocate frequency space to private companies for use in the emerging technology of cellular communications. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public. On April 3, 1973, standing on a street near the Manhattan Hilton, Mr. Cooper decided to attempt a private call before going to a press conference upstairs in the hotel. He picked up the 2-pound Motorola handset called the Dyna-Tac and pushed the "off hook" button. The phone came alive, connecting Mr. Cooper with the base station on the roof of the Burlington Consolidated Tower (now the Alliance Capital Building) and into the land-line system. To the bewilderment of some passers-by, he dialed the number and held the phone to his ear. Who is he? Cooper grew up in Chicago and earned a degree in electrical engineering at the Illinois Institute of Technology. After four years in the navy serving on destroyers and a submarine, he worked for a year at a telecommunications company. Hired by Motorola in 1954, Mr. Cooper worked on developing portable products, including the first portable handheld police radios, made for the Chicago police department in 1967. He then led Motorola's cellular research.

What could the first cell phone do?

The first cell phone was just like the home phones when Bell Telephone dominated the industry. You could make and receive phone calls. No voice mail. No text messages. It might have had redial, or even a speed dial. But very likely not much more than that. Oh, it was also about the size of a brick (but weighed half as much) and the battery wouldn't last more than an hour or two of talk time. Yeah, we've come a very long way since then.
