How can you broadcast from an item with a 3.5mm jack to multiple wireless headphones. Bluetooth. Radio?
A wireless in-ear monitor system can be used to broadcast an audio signal. The 3.5mm audio is connected to a transmitter. Each listener then wears an in-ear receiver belt pack, and connects their own earphones or earbuds into the receiver. These are the systems you see musicians using on stage. A pro system like this isn't cheap, however, with a single transmitter/receiver package (in stereo) selling for at least $500.00. Each additional listener will need a receiver and phones (an additional $300 or so per person). These systems are UHF radio frequency. Bluetooth is not used in this fashion because of its limited range, audio quality and 1-1 pairing topology.
What is LOS and NLOS?
Line-of-sight (LOS) is a condition where a signal travels over the air directly from a wireless transmitter to a wireless receiver without passing an obstruction. LOS is an ideal condition for a wireless transmission because the propagation challenge only comes from weather or atmospheric parameters and the characteristic of its operating frequency. In LOS environment, signal can reach longer distance with better signal strength and higher throughput. Conversely, non-line-of-sight (NLOS) is a condition where a signal from a wireless transmitter passes several obstructions before arriving at a wireless receiver. The signal may be reflected, refracted, diffracted, absorbed or scattered. These create multiple signals that will arrive at a receiver at different times, from different paths, and with different strength. Consequently, wireless systems developed for NLOS environment have to incorporate a number of techniques to overcome this problem and that make the systems more complex than those for LOS. But NLOS capable systems simplify network planning and site acquisition.

What is Wireless transmission system?
A wireless transmission consists of at a minimum: input signal (the data or analog signal you wish to transmit), transmitter, 2 antennas, space (the final frontier) and a receiver/reproducer. This only makes one way transmission possible. You would need an additional: transmitter, receiver/reproducer and 2 antenna couplers (allows both a transmitter and receiver to use the same antenna) to have 2 way communication. A basic transmitter consists of a power source, a signal generator (oscillator), signal converter/amplifier, mixer (mixes the oscillator and amp signals to create the transmitted signal), output amplifier. a receiver is similar to a transmitter except instead of mixing the signal with the oscillator signal it removes the oscillator signal. Systems can be much more complicated depending on power needs (distance between antennas, frequency interference...) and application (encoder/decoder, security or digital conversion).
Where and when did the radioman rate originate?
The beginnings of the radioman rate in the Navy dates back to the early 20th century...approximately 1914-1918 with the advent of the Marconi wireless transmitter/receiver. The actual rate of radioman was established in 1921 and was merged with IT (Information Systems Technician) in 1999.
How do you improve wireless power?
You are not alowed to modify the power of your WiFi transmitter (by law) because if you did this you would spoil the WiFi systems of your neibours.
What is a duplexer?
A duplexer is a device that allows bi-directional (duplex) communication over a single channel. In radar systems, a device that isolates the receiver from the transmitter while permitting them to share a common antenna. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter. Note 2: A duplexer must provide adequate rejection of transmitter noise occurring at the receive frequency, and must be designed to operate at, or less than, the frequency separation between the transmitter and receiver. Note 3: A duplexer must provide sufficient isolation to prevent receiver desensitization.Braimah prosper
How does wireless remote control for crane works?
Radio remote control: The wireless equipment or machines works on radio waves technology. The artificial radio wave is generated to control the electronic machine such as the overhead crane is called radio remote control. The overhead crane is used for industrial purposes which move and travels above the head at a particular height. The device can move the EOT crane in different directions like cross travel, long travel, and hoist. The hoist is used for lifting and lowering heavy objects. The transmitter and receiver are the two main components that are used for sending and receiving the signal for communication. The radio transmitter has various types such as 8 button radio remote, 12 button radio remote, and joystick radio remote control devices. These all types of devices have their features and specifications. Principle of wireless remote control for crane: The transmitter and receiver are used for communication to control the machines. The transmitter is a handy and small device that can be easily carried by one hand. The operator uses the transmitter device while the receiver is attached to the overhead crane. Communication happens between the transmitter and receiver when the transmitter sends the signal. Whenever the operator pushes the button on the transmitter device a data-packed is sent to the receiver in an encryption form. That means data is first converted to the cipher text from the plain text. When the signal reaches the receiver first decodes the data, the data is converted from cipher text to plain text. This encryption technique is used for the safety of data packets and the communication is not affected by the external entity. More than 10 times in a second communication happens between the transmitter and receiver. And the transmitter device can range from 10 meters to 200 meters distance for communication. While communicating with the receiver the transmitter device detects many things like how many data packets are sent, the communication, the speed of communication, the loss of data packets, successful transmission, number of errors, the signal quality, the distance, and many more. The hopping method is followed by the transmitter and receiver to circumvent unnecessary interference. The EOT crane remote control device provides the interlocked systems in a pair while in use. That means two buttons in a pair cannot be used at the same time. If an up button is pressed on the transmitter device at that time down button cannot be pressed. And we have to keep pressing the up button until the overhead reaches its destination. Features of overhead crane remote control systems: The radio remote control can range from 10 meters to 200 meters. The device uses the 2.4 GHz frequency band technology. The transmitter device is made in such a way that it prevents corrosion and shock. More than 10 times in a second communication happens between the transmitter and receiver. The communication can range from 10 meters to 200 meters. The transmitter device is highly optimized and customized while in use. The crane remote control coating is so strong that it can be used for harsh industrial conditions. The transmitter is a wireless device and works on the battery or charging systems. The remote control adjusts the power automatically according to the distance. The transmitter device works well at a very low battery also. Precedence of crane remote control: The main advantage of the crane remote control system is that it works on the battery or charging replacement system and hence the overhead crane can be operated from a long distance also. And the operator doesn't have to sit inside the crane which makes risk free. The battery used in the transmitter device is durable and can last long up to 6 months. The communication is very safe and secure between the transmitter and receiver. The communication happens rapidly i.e. 10 times in a second. The transmitter uses wireless technology for communication and if any error or lag is found in the systems then the transmitter stops working immediately. According to the distance, the power is automatically adjusted by the transmitter device. That means if the distance is less between the transmitter and receiver then less power is consumed by the device. And if the distance is far then the power is adjusted according to the distance.
What is radar system?
Radar systems usually use wavelengths and are associated with digital signal processing. They consist of a transmitter, antenna receiver, switch, data recorder, processor, and display. Radar systems are used to track things including weather.
