Which of the following WAN technologies has the HIGHEST latency?
A.
ADSL
B.
LTE
C.
Satellite
D.
WiMAX
Explanation:
Satellite WAN latency is the delay caused by the physical distance a signal must travel from earth,
to the satellite, and back to earth to complete a round-trip transmission. Because of the physics
involved in the round-trip-time (RTT), end-to-end latency can take 600 milliseconds or more due to
geosynchronous satellites orbiting miles above the earth.
