∙ 13y ago
Remote control employs a frequency modulation (FM) radio frequency of 433 MHz transmission that has a strength range of 400 mt outdoors or 200 meters indoors
[ through a wall ] to operate any electronic /electric relay driven gadget through a radio frequency decoder.433 MHz frequency can be produced by a small (size of a postage stamp) simple 4 bit chip that has no complicated circuit and better than complex inconvenient ones for higher range.
433 MHz frequency modulation radio waves are best suited for short range applications produced from compact micro circuit and therefore useful for short range use

What two windows applications use the RDP protocol and port 3389?
RDP. Remote Desktop Protocol (RDP) is used by the Windows Remote Desktop and Remote Assistance utilities to connect to and control a remote computer. Remote Desktop and Remote Assistance listen at port 3389.
What are the uses of a PC remote?
Remote controls for personal computers are generally used to control movie, TV, radio, and music applications. A remote control, relatively smaller than a keyboard, is suitable for playing, pausing, stopping, and rewinding or fast-forwarding files, or changing channels.
What are the applications of power line communication?
used for remote metering & control. The existing line in a building can be used as a local area network backbone or integrated in to a wide area network.
What is the function of variable frequency drive?
The function of a frequency drive is to control the speed of an electric motor. In general, a frequency drive converts the ac supply voltage into a dc voltage and then converts this dc voltage into a ac voltage of which the amplitude (voltage) and the frequency can be varied. Giving you the possibility to fully control the speed of the motor. Applications: (big) ventilators, pumps, cranes, elevators and virtually all other applications where electric motors are used.
Will the frequency used to control a remote controlled toy interfere with any household appliances?
There will be no problems whatsoever. Remote controlled toys operate on special frequencies cleared for use by the FCC, so they do not overlap with other devices.
What is a Canon remote controller RC 1 used for?
The Canon remote controller RC 1 is used to control the RC 1 remote control car. A remote control car is usually a small car that can be controlled from a distance with a controller.
Can a projector be used with a remote control device?
Yes one to use would be the Hitachi Projector Remote Control
In what products do microwave tubes find application?
Microwave tubes were primarily used in high and ultrahigh frequency applications such as radars, telecommunications equipment, military communication and control systems
What is a remote control used for?
A remote control is used to control an electronic device form a distance without wires. It uses infrared or radio frequencies to transmit the data to the device.
How does radio technology work, and what are the applications of radio remote control?
Radio waves are used to control any type of equipment and machines wirelessly, such kind of a control system is called a Radio Remote Control. How does radio technology work? The signal transmitted or received by the antenna If the transmitter transmits the signal or the receiver picked up the signal, a bandpass filter allows only desired frequency and attenuates the other frequency signal. While Radio waves passing through an air medium, there are many different RF waves are present so, the antenna tunned the required frequency and receives the specific signal. For selecting the length of the antenna, the formula is λ = c/f where λ = wavelength C = Speed of light (3x108 m/s) F = desired frequency Now, we see the applications of crane wireless remote control The remote radio control is used in different applications. The control panel used in various cranes such as • Electric Hoist • EOT Cranes • Tower Crane • Goliath crane • Mobile Crane • Gantry Crane Electric Hoist: An electric hoist is an appliance used to lift or move heavy or light equipment. Hoist crane wireless remote control is used for lifting the crane and avoid the accident. Electric hoists are available in different types. EOT Cranes: EOT stands for Electric Overhead crane. It is the most common type of overhead crane remote control system called a bridge crane. EOT crane control panel operated by crane pendant with the help of electricity. EOT cranes lift load up to 500 tonnes with 60 meters span. Tower Crane: Tower crane remote control is used in civil construction sites. It handles the heavy materials, tools related to construction. All the self-erecting tower cranes are remote controls. Most of the construction sites prefer remote control cranes to avoid accidents and safety purposes. Goliath Crane: Goliath crane is similarly an overhead crane that has a single girder or double girder establishment and it is supported by separate legs that move on along the track. These cranes are used in outdoor applications. Mobile Crane: A Mobile crane is a wired-controlled crane with a lifting capacity of up to 160 tones. These cranes are mounted on crawler or rubber tire carriers. This type of crane can move to different locations very easily. Gantry Crane: To lift extremely heavy objects then a gantry crane is a great option. Gantry cranes are mainly used in shipbuilding because of its handle very large engines and parts. It is the type of overhead crane control with a single girder or double girder configuration.
What is the meanting of a remote controller?
A remote control toy is a toy that can be controlled from a distance using a handheld device.
What is the apple white remote control model a1156 used for?
The apple white remote control model a1156 is used for controlling the Mac, iPod or iPhone
