most modern phones do not have infrared anymore. This technique was used with old phones to transfer data wireless form phone to phone or from the phone to the computer. However this technology is now deprecated because it was too slow.
There are new protocols for the technology making it much more effective then it use to be and also much faster but manufacturers have not embraced this.
No they do not they only thing they use is a short wave ffrequency to send messages etc. they also use bluetooth. there used to be a device called infrared but it wasnt actually infrared just a short wave frequency.
Some old phones use infrared to transfer files.
Instruments for detecting infrared radiation include heat-sensitive devices such as thermocouple detectors, bolometers, photovoltaic cells, and photoconductors.Pranay karnatak
Infrared rays are used in television remote controls
Radio waves
Radio waves, microwaves, infrared and visible light can all be used for communication. Radio waves – are used to transmit television and radio programs. Microwaves – are used to transmit satellite television and for mobile phones. Infrared – is used to transmit information from remote controls.
generally infrared rays or microwaves sometimes are used in a Bluetooth but it depends upon the usage,speed, and range for low range and less efficiency infrared rays are use whereas for high intensity and range microwaves are used.
One of the technologies used in mobile phones is a fractal aerial design.
Simple Mobile has a variety of phones on their website that are compatible with their service. Phones that are compatible with T-Mobile can also be used with Simple Mobile.
None, mobile phones arent made up of minerals
Used mobile phones can be bought from online trading and bidding sites such as eBay or at T-Mobile stores. Many local classified newspapers and websites also offer used mobile phones for sale.
No, they are not bad at all. Infrared rays are long wavelengths that supply heat and are often used therapeutically to warm tissues before and during thermotherapy.
IR rays are just electromagnetic rays so the properties of infrared rays resemble to those of EM waves which can be easily blocked by thick materials. Lead is commonly used to block them.
