What is simplex in networking? |
|
Answer» In a Simplex operation, a single signal is transmitted and continuously goes in the same direction. The transmitter and receiver operate on the same frequency. When two stations transmit to each other on the same frequency at the same time, the mode is known as half-duplex (not simultaneous). Half-duplex, however, is commonly known as Simplex (not simultaneous). Sometimes, at high and microwave wireless frequencies, simplex or half-duplex mode will not be adequate for providing enough range for communications. To increase the effectiveness of the range, wireless repeaters are employed. There are several different frequencies that the incoming signal might be than the outgoing signal, thus preventing the transmitted signal from overwhelming the repeater receiver. Repeaters, strategically positioned at significant locations with wide line-of-sight coverage areas, may greatly enhance the range of a wireless communications system. |
