Transmission
frequency is typically measures in MHz (megahertz) or GHz (gigahertz) the number of times in a second that an electrical signal can change
bandwidth is measures in Mbps (megabits per second) or Gbps (gigabits per second) refers to the data you could theoretically transmit
throughput is measured in Mbps (megabits per second) or Gbps (gigabits per second) refers to the data actually received across a connection

latency is the brief delay between the instant when data leaves the source and when it arrives at its destination
the duplex is the direction which the signal travels over the media and the number of signals that can traverse the media is the multiplex

Wireless Transmission
commonly called the airwaves, spans frequency ranges or bands between 9 kHz and 300 GHz
-
spectrums
FHSS (frequency hopping spread spectrum) short bursts of data transmitted from frequency to frequency
DSSS (direct sequence spread spectrum) transmits data in chips over multiple frequencies at the same time
