duplex communication การใช้

• There are two types of duplex communication systems : full-Duplex and half-Duplex.
• All these three standards define both full-duplex and half-duplex communication.
• The two devices that communicate simulate full-duplex communication by quickly turning the link around.
• Circuits were character oriented and the network was oriented towards interactive character-by-character full-duplex communications circuits.
• Push-to-talk cellular calls similarly provide half-duplex communications  while one person transmits, the other ( s ) receive.
• These systems claim symmetric and full duplex communication in excess of 1 Gbit / s in each direction.
• The main difference is that it uses a single two-way communication data line for half-duplex communication rather than separate transmit and receives lines.
• In contrast, a PCI Express bus link supports full-duplex communication between any two endpoints, with no inherent limitation on concurrent access across multiple endpoints.
• A perhaps more efficient transport for real-time messaging is WebSocket, a web technology providing for bi-directional, full-duplex communications channels over a single TCP connection.
• Business frequencies in the UHF range are also licensed in pairs to allow for repeaters, though taxi companies usually use the pair for duplex communications.
• It offers the potential for full duplex communication ( transmitting and receiving at the same time with a single shared antenna over a single frequency ).
• Until approximately the 1970s most telephones used a rotary dial, which was superseded by the modern duplex communication, meaning they allow the people on both ends to talk simultaneously.
• Indeed, for example, that is the case for echoplex error checking, which " requires " full-duplex communication, so that received data can be echoed back as they are being received.
• IrDA data communications operate in half-duplex mode because while transmitting, a device s receiver is blinded by the light of its own transmitter, and thus full-duplex communication is not feasible.
• In developing HTTP Speed + Mobility, Microsoft built upon both Google's proven SPDY protocol and on WebSocket, which is a web technology providing for bi-directional, full-duplex communications channels over a single TCP connection.
• Inside the airtight enclosure are proprietary neodymium drivers and two opposing passive bass radiators along with a newly designed omnidirectional microphone, which is capable of 360-degree sound input with improved echo-cancellation and full duplex communication.
• Typical walkie-talkies resemble a telephone handset, with a half-duplex communication device; multiple walkie-talkies use a single radio channel, and only one radio on the channel can transmit at a time, although any number can listen.
• While the Internet phones allow full-duplex communications ( in other words, two people can talk at the same time ), in reality, it ends up more like half duplex, an experience comparable to two-way radio communication.
• There may also be an aggregation port for full-duplex traffic, wherein the " A " traffic is aggregated with the " B " traffic, resulting in one stream of data / packets for monitoring the full-duplex communication.
• Windows Communication Foundation ( WCF ) comes to the rescue when we find ourselves not able to achieve what we want to achieve using web services, i . e ., other protocols support and even duplex communication.
