Switched Ethernet
A collision occurs.
Collisions
Two way radios can both transmit and receive signals. It uses two different radio frequencies to carry the two conversations simultaneously.
half duplex modem is each station can transmit and receive but not at the same time. full duplex modem is both stations can transmit and receive simultaneously.
spread-spectrum technology
Omnidirectional
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once
The way a duplex functions in a cell phone is by having a two - way communication in which both terminals can transmit simultaneously.
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once
Multicasting
transmit a clear message in multiple view
Orthogonal Frequency Division Multiple Access. It has something to do with the way cell phones transmit signals.
