What else can I help you with?
Where does wireless transmit and receive signal from?
It has an access point which transmit signal to the client and receive.
How can you configure a mobile device so it cannot connect to any network?
Configure the mobile device to use airplane mode, tap the settings app and turn Airplane Mode on which disables all antennas so the device can neither transmit nor receive signals.
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 are the Differences between horn antenna and waveguide?
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
What is the need for antennas what are transmitting antennas what are receiving antennas?
Antennas transfer energy from a cable into the airwaves efficiently. Any transmit antenna can also be a receive antenna and viceversa. If you wish to transmit high power from an antenna, usually heat generation or high voltage is a concern that can destroy the antenna. To prevent problems, high power antennas require thicker wires and sometimes insulators to prevent overheating/burning and arcing. Many antennas can simply be made of wire of a simple length and they'll be very efficient. The length of an antenna changes it's efficiency to the cable. If you want the antenna to be efficient, you must size it to match the cable impedance. Usually the length of a single wire exiting above a metal plate is one quarter wavelength or 1/4 x 11,803/frequency in megahertz. For FM radio on an automobile, some antennas have motors that extend out of the body of the car. The height (inches) should be 1/4 x 11,803/100 megahertz or just under 30 inches. TV antennas above a house are most often a set of half wavelength wires, so change the 1/4 to 1/2 in the formula above. They use many different wire lengths to cover all the frequencies in the television band, which extends from about 50 megahertz to around 600 megahertz. Cell phone frequencies were picked partly to make the antennas small and partly so that cell phone reception can enter buildings with rebar reinforcement. Cell phone frequencies are roughly 800 megahertz and 1800 megahertz. Receiver antennas are often made smaller than either transmit or transceiver antennas. If you open up the back of an older transistor radio, you are likely to find a bar made of ferrite material with an insulator and wire wrapped around that. The wire is wrapped a number of turns to match the impedance required by the circuit. The ferrite bar is able to focus signals to itself which in turn induces a current in the coil. While impedance is an important issue, simple dipole antennas can be sized by the 468/Frequency in mHz formula. It will give the the length of an antenna in feet. You divide the outcome by 2 to find out what each side length should be. The impedance of an antenna can ofter be adjusted by its shape. The 90 degree V shape yields a near perfect 50 ohms impedance which is commonly used for transmitters and transceivers where as the flat top diode has a higher impedance. The ARRL has good books on antennas. You might want to go to the library and look at a few of them.
What is the minimum vertical distance you must maintain between the midpoints of the transmit and receive antennas?
5ft. (1.5 m)
Which brand of antenna is best?
Omnidirectional is the best brand for antennas because its ideal for high gain and wide coverage. They transmit or receive effectively in every direction.
Why do radio altimeter have 2 antennas where as weather radar have 1?
A RADAR altimeter must have 2 antennas (one transmit, one receive) so that it can operate continuously making altitude measurements by matching modulation and carrier phase of received signal with transmitted signal.A weather RADAR needs only 1 antenna because it operates in a pulsed multiplex mode: the antenna is used as a transmitter antenna to send a short pulse of carrier, then is used as a receiver until the last possible reflection from the furthest distance could return. During this time the antenna has rotated only a tiny amount. The transmit/receive multiplex cycle continues as the antenna rotates 360 degrees.A targeting RADAR operates much like the weather radar but it sweeps back and forth over a limited angle instead of in a full 360 degree circle. (e.g. 120 degrees, 90 degrees, 60 degrees, 45 degrees)
Where does wireless transmit and receive signal from?
It has an access point which transmit signal to the client and receive.
How do antennas work to receive and transmit signals?
Antennas work by converting electrical signals into electromagnetic waves for transmission, and vice versa for reception. When a signal is sent through the antenna, it creates an electromagnetic field that propagates through space. This field can be picked up by another antenna tuned to the same frequency, allowing for communication.
What are the uses of antenna?
A transmit antenna sends radio energy from an electronic circuit into space. A receive antenna captures radio energy from space and connects it to an electronic circuit. Most people own several antennas, for example in transistor radios, mobile phones, keyfobs for locking the car, television satellite dishes or antennas on chimneys.
How do satallites get signals from earth?
Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
What does radar look like?
like a poke radar
What is Half- duplex?
Half duplex communication means that a system may transmit and receive signals, but not at the same time. It has to switch over from transmit to receive, and vice-versa. Think of an analogy of a walkie-talkie; when you press the transmit button you cannot hear or receive a message until you release the transmit button.
What does TX and RX stand for?
They are abbreviations for Transmit and Receive, respectively.
What is the opposite of transmit?
The opposite status is to receive. The failure to transmit would be to withhold or cut off.
What does receive mean on your modem?
Part of your modems specs are its Transmit and Receive levels . It varies from company to company but the basic rule is transmit between 32-52 and receive between -10 and +10.
