How many frequency bands does the military use?
The military typically uses several frequency bands for various communication, radar, and navigation purposes. These bands can be broadly categorized into low frequency (LF), high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), super high frequency (SHF), and extremely high frequency (EHF). Each band serves different operational needs, with some dedicated to secure communications, while others are used for surveillance and targeting. The exact number of frequency bands may vary based on specific military applications and technology advancements.
Why dipole antenna not used for high frequency?
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
What is a high end frequency scanner?
A: It is a terminology to imply that the scanner will be used at the hi end of frequency as opposed to low frequency
What is the frequency range used in wireless communication?
2.4GHz is used & OFDM
What is fdd interface?
The FDD (Frequency Division Duplex) interface is a communication method used in wireless systems where separate frequency bands are allocated for uplink (transmitting data from a user device to a base station) and downlink (transmitting data from a base station to a user device) transmissions. This allows simultaneous two-way communication, improving efficiency and reducing interference. FDD is commonly used in cellular networks, such as LTE and 5G, enabling better performance in high-capacity environments.
What are the characteristics and properties of high frequency waves?
High frequency waves have a short wavelength and high energy. They can travel long distances and penetrate through obstacles easily. High frequency waves are commonly used in technologies like radio communication and medical imaging.
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.
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 does Sending out a pulse of high frequency radio waves?
Sending out a pulse of high frequency radio waves involves transmitting electromagnetic radiation at a fast rate. This can be used for applications such as communication, radar systems, and medical imaging. The high frequency allows for fast transmission and reception of data or information.
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 sound has a frequency too high to be detected by humans?
Ultrasound has a frequency higher than the upper limit that humans can detect, which is typically around 20,000 Hz. This type of sound is used in various applications such as medical imaging, cleaning, and communication.
What are the characteristics and applications of low frequency waves?
Low frequency waves have longer wavelengths and lower energy compared to high frequency waves. They can travel long distances and penetrate obstacles like buildings and walls. Low frequency waves are commonly used in radio communication, submarine communication, and medical imaging techniques like MRI.
What are the characteristics and applications of high frequency signals?
High frequency signals have a short wavelength and high energy. They are used in applications such as telecommunications, radar systems, and medical imaging. These signals can carry large amounts of data quickly and are also used in wireless communication technologies like Wi-Fi and cellular networks.
What are the characteristics and applications of high frequency waves?
High frequency waves have short wavelengths and high energy. They are used in various applications such as telecommunications, radar systems, medical imaging, and industrial processes. These waves can penetrate materials and provide detailed information for imaging and communication purposes.
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 the uses of UHF?
UHF (Ultra High Frequency) is commonly used for television broadcasting, two-way radio communication, GPS systems, and RFID (Radio Frequency Identification) technology. It is also utilized for wireless networking, satellite communication, and remote control devices.
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.
