Why is Radio Frequency used in mobile communication?
the frequency used in mobile communication should be greater then 30mhz so cannot be reflected by the ionosphere thats why we are using a frequency of range less ghz so called "radio waves"
What is the telephone frequency range used for communication?
The telephone frequency range used for communication typically falls between 300 Hz to 3.4 kHz.
What is the correct term when describing the frequency range of 3khz to 300ghz?
The frequency range of 3 kHz to 300 GHz is commonly referred to as the "radio frequency (RF) spectrum." This range encompasses various types of electromagnetic waves used for communication, radar, and other applications. Within this spectrum, different segments are designated for specific uses, such as television, mobile communications, and satellite transmissions.
Which frequency do humans hear the best?
Humans hear best at frequencies between 2000 to 5000 Hertz. This range is where human hearing is most sensitive, allowing us to detect sounds with greater accuracy and clarity. Sounds within this frequency range are key for speech recognition and communication.
What are the potential applications of extra low frequency technology in modern communication systems?
Extra low frequency technology has potential applications in modern communication systems for long-range communication, submarine communication, and earthquake detection.
What was the first ever mobile phone invented?
Wasnt a phone as such, first wireless communication was through Morse code using long range frequency devices. Very primative now but still effective if you know how.
What frequency range of tetra?
Tetra communication systems typically operate within the frequency range of 380-400 MHz for uplink and 390-410 MHz for downlink transmissions.
What is the down link frequency to earth?
The downlink frequency to Earth, in the context of communication satellites or spacecraft, refers to the frequency at which data is transmitted from the satellite to Earth. The specific frequency used can vary depending on the satellite system and the communication protocol being employed. Generally, downlink frequencies for satellite communication are in the microwave frequency range, typically between 1 to 50 GHz. The choice of downlink frequency is influenced by factors such as transmission range, atmospheric absorption, and regulatory requirements.
What type of wave has a frequency of 10 to the 8 power hertz?
A wave with a frequency of 10^8 hertz falls within the radio frequency range of the electromagnetic spectrum, specifically in the UHF (Ultra High Frequency) band. This frequency is commonly associated with television broadcasting, mobile communications, and various wireless technologies. UHF waves can travel long distances and penetrate buildings effectively, making them ideal for communication applications.
What is the wave length of mobile?
In mobile telecommunication wave length is another word for frequency. and the length can be anything provide that it is allowed by the government
What is 3 -30 megahertz?
3 - 30 megahertz is a frequency range within the radio frequency spectrum, commonly used for radio broadcasting, television broadcasts, and various communication systems. It falls in the low frequency range compared to higher frequency bands like microwaves or infrared.
What is the difference between the side band and a side frequency?
In radio communication, a sideband refers to the band of frequencies containing the signal that is beside (or adjacent to) the carrier frequency. A side frequency, on the other hand, refers to a specific individual frequency within a sideband. Think of the sideband as a range of frequencies and a side frequency as a single frequency within that range.
