Which of the following WAN technologies has the HIGHEST latency?
A. ADSL
B. LTE
C. Satellite
D. WiMAX
Answer: C
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.
