which mode of communication simplex half duplex full duplex is suitable when a computer communicate to a printer for printing?also give one more example of that mode
Answers
Answer:
communications via a single antenna on any wireless device. Also referred to as a Simultaneous Transmit and Receive (STAR) on the same frequency channel, PSI’s technology could effectively double the capacity of any wireless communication network within the existing allocated RF spectrum while saving wireless service providers billions of dollars in spectrum licensing and relocation fees.
First demonstrating this capability in 2009, PSI has now invented, developed and demonstrated STARbox™; a new radio front-end circuit (hardware that interfaces directly with the antenna) that provides high isolation between the transmit path and receive path inside any radio or wireless device. Some of the advantages of PSI’s STARbox solution include:
Enables STAR capability through a single existing antenna
Compatible with worldwide network standards
Simple, easy to include in existing radio designs
Does not require precise spacing among multiple antennas to form nulls
Can be made backward compatible with existing wireless networks
