Simplex provides the highest signal quality since the path between driver and receiver is uncomplicated.
Simplex architectures are also a better choice when the speed of an interface gets above a few hundred megabits per second.
When considering signaling rate for devices, it's important to note that a maximum signaling rate may often be featured based on a minimally acceptable parametric quality, such as output voltage, transition time, or jitter.

 Q&A Telephone Interconnects
Although the preferred method for interfacing a simplex interconnect is using Discriminator or Detector Audio, where internal COR mobile detection is used, it may not be possible in cases where this audio is only available as squelched-controlled audio in the receiver.
Using the receiver schematic diagram, determine the circuit that derives the squelch logic and verify that the signal is a DC level change of 0 to 5 or more volts from a no-signal to a received signal condition.
In some receivers there are similar functions that may be used as a signal strength indicator, and are DC levels that change too slowly, or that change proportional to the received signal level, and are not suitable to serve properly as COR logic.

If a new QoS signaling protocol is to be created or if an existing one is to be modified to alleviate this situation, it is necessary to first produce a set of requirements which cover all potential problem areas.
Must be independent from different mobility protocols Although the QoS signaling may be able to take advantage of specific mobility protocols for optimized operation, it should be designed independently from mobility protocols in the sense that it can still perform the same functionality when one or more of these mobility protocols are not used.
The signalling messages need to be visible to the network QoS nodes, but also the data packets that would need a specific QoS need to be identified.

 Re: newbie networker, old-timey networking parts query
The twisted-pair stuff uses "current-mode" amplifiers, which aren't well suited to either simplex signaling (where signals travel both directions in single coax or a pair) or the occasional "collision".
The network cards must then either be able to detect/correct collisions, or to setup for simplex (versus duplex) transmisions.
In a windoze world, where the user isn't permitted to know anything about what their hardware is doing, it is becoming increasingly harder to change the hardware settings from the defaults which either mickeysoft or the computer manufacturer desire.
