What are some examples of RF technology?
Radio Frequency is a wireless technology consisting of a transmitter and receiver tuned to the same frequency
What is the frequency range used on all audio receivers?
The frequency range used on all modern audio receivers is 10.7 to 12.75 GHz. The IF range is 950 to 2150 MHz. Audio receivers are also known as radios.
Why high frequency is used in communication than low frequency?
High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.
What is voltage sweep generator?
A: Sometimes a spectrum of frequency must be analyzed a voltage to frequency converter can be used to sweep a range of frequency just by changing some DC level.
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
In most cases the frequencies used by wireless networks are in what frequency band?
The common wireless frequency is 2.4 Ghz. Some wireless networks may use the 5 Ghz frequency range.
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 are some examples of RF technology?
Radio Frequency is a wireless technology consisting of a transmitter and receiver tuned to the same frequency
What are 2 most common wavelengths used for public wireless communication?
Infrared (IR) technology and Radio Frequency (FR) technology.
What is the price range to set up a wireless network connection from different communication companies?
The price range to set up a wireless network connection from different communication companies is between 20 and 50 dollars. The price differers depending on the hardware and software used.
What were the early wireless keyboards used for?
they are used for communication.
What is the difference between frequency division multiplexing and freq division multiple access?
The basic difference between fdm and fdma is that fdm is used in wired system where as fdma is used in wireless communication.
What are the various physical and wireless transmission media?
Physical Media Twisted-Pair Cable Coaxial Cable Fiber-Optic Cable Wireless Media Broadcast Radio Cellular Radio Microwaves Communication Satellite
What is the operating frequency of optical fiber?
In Optical Fiber Communication system 1300-1550 nm range wavelengths are used.. Reason for tis s "In this range only we can acheive low attenuation with zero dispersion"
Function of radio frequency?
Radio frequency refers to the range of electromagnetic waves with frequencies between 3 kHz and 300 GHz. The primary function of radio frequency is to facilitate wireless communication. It is used in various devices and technologies such as radio, television broadcasting, cell phones, Wi-Fi, and Bluetooth, allowing for the transmission and reception of audio, video, and data over long distances without the need for physical cables. Additionally, radio frequency is also used in other applications such as radar systems, satellite communication, and medical imaging.
What is the possible reason for degradation of wireless communication when microwave is in used?
Wireless communication is usually a form of radio communication. Radio communication uses a part of the electro-magnetic spectrum of radiation. Microwave ovens also use electro-magnetic radiation. If you have a radio that's operating close to the microwave range, or maybe an microwave oven that has a wide spectrum, then the oven can interfere with the radio.
Which part of the electromagnetic spectrum is commonly used by wireless LANs?
Radio Frequency
