Assuming a half-duplex operation mode, a node cannot transmit and receive simultaneously.
VHF (138MHz-225MHz), UHF (406MHz 512MHz) and 869MHz (863MHz--870Mttz) versions of the AutoLog WSN are available for simplex or half-duplex operation. Applications include oil and gas applications with complicated narrow band SCADA networks.
* The ability to support full-duplex and half-duplex operation, high-speed non-blocking, store-and forward switching and auto-negotiation as well as Layer-2 switching.
And because SCSI protocols are not restricted to half-duplex operation, SAS will also support full-duplex transfers, allowing data to be transferred simultaneously in both directions to maximize bandwidth.
Supporting both full and half-duplex operation, the devices meet a range of voice applications.
Half-duplex operation is accomplished with SPDT switches and the corresponding control logic.
By contrast, SATA is restricted to half-duplex operation, in which data transfer in one direction must be completed before transfer in the opposite direction can occur.
Available in multimode or single-mode (1,300 nm or 1,550 nm), the switch supports both full- or half-duplex operation, and distances up to 100 km.--TC Communications
The software automatically negotiates the Ethernet speed (10Base-T or 100Base-T), as well as choosing between full- and half-duplex operations. It has a built-in MDI/MDI-X auto crossover function.
It automatically negotiates the Ethernet speed (10Base-T or 100Base-T) as well as to choose between full- and half-duplex operations. It has a built-in MDI/MDI-X auto crossover function, and it acts as a wireless Ethernet bridge that is transparent to all Ethernet protocols.
