What else can I help you with?
Why can't the signals used in radio be used for mobile communication to make it harmless?
They are; mobile phones are no more dangerous than a radio station.
What radio is a form of broadcast radio that is used widely for mobile communications specifically wireless modems and telephones?
The form of broadcast radio widely used for mobile communications, particularly in wireless modems and telephones, is known as cellular radio. This technology allows for the transmission of voice and data over a network of radio cells, enabling seamless communication across vast areas. Cellular radio employs various frequency bands and modulation techniques to ensure efficient and reliable communication for mobile devices.
What is a wave with the longest wavelength and lowest frequency?
The type of wave with the longest wavelength and lowest frequency is a radio wave. These waves have frequencies ranging from about 3 kHz to 300 GHz and are used for various forms of communication, including radio broadcasts and mobile phone signals.
Define downlink frequency?
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
Does any radio frequency used for laser communication?
no. LASER uses light frequencies.
Which types of electromagnetic waves are used for radio communication?
Radio communication typically uses electromagnetic waves in the radio frequency range, specifically in the Very High Frequency (VHF) and Ultra High Frequency (UHF) bands. These waves have wavelengths that are suitable for transmitting signals over long distances and are commonly used for broadcasting, two-way radio communication, and cellular communications.
What term is often used to describe interference of radio waves?
The term often used to describe interference of radio waves is "radio frequency interference" (RFI). RFI can disrupt the normal operation of electronic devices that rely on radio frequency signals for communication.
What part of the electromagnetic spectrum has the lowest frequency?
The part that we call "Extremely Low Frequency Radio Waves".
What is 26B in a HF?
26B typically refers to the specific frequency band within the HF (high frequency) spectrum, specifically around 26 MHz. This band is commonly used for various radio communication purposes, such as amateur radio, shortwave broadcasting, and maritime mobile communications.
Do cell phones use radio waves or microwaves?
Microwaves are radio waves.Technically, "microwave" is the term used to designate radio communication onfrequencies above 3 GHz. Cellular and mobile data service doesn't operate inthat frequency range. But microwave systems operating in bands between5.8 GHz and 80 GHz are used to link the individual cellular and mobile data sitesto each other, and to the mobile switching centers.
What are two portions of the EM spectrum are most commonly used for communication?
The two portions of the electromagnetic spectrum most commonly used for communication are radio waves and microwaves. Radio waves are utilized for various communication technologies, including AM and FM radio, television broadcasts, and cellular networks. Microwaves are primarily used for satellite communications, mobile data transmission, and point-to-point communication systems. Both of these frequency ranges enable efficient transmission of information over long distances.
What type of radiation is used in mobile phone communication networks?
radio waves (part of the electromagnetic spectrum)
