The answer is also False, from the Network + Guide to networks 5th edition.

Line-of-sight propagation is also said as electro-magnetic radiation or acoustic wave propagation. This includes light emissions traveling in a straight line.
The biggest problem with satellite broadband connections is the latency (time it takes to make a connection). Instead of your signal traveling through a wire with 40-100ms travel time, you can take 800-1200ms to complete the connection. Satellite may be good for streaming videos, but it is almost worthless to use for playing high-speed interactive video games. During the 1+ second it takes you to see an opponent move on your screen, the bad guy may be able to shoot at you several times before you even know he is there.
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.
You could attach an external directional antenna. Google for 'wireless antenna'.
False. You probably have figured it out already, but video signal (dubbed CATV or Cable TV) was previously the only thing traveling through the cable coax you use today to transport IP data and video data. As a result, the downlink is going to be much higher than the uplink due to the bandwidth of the signals traveling through the coax. With that in mind, Cable Broadband remains asymmetrical.

Noise and Latency
Checking VoIP latency and voice quality and signal transmission.
nerve signal
It is the traveling of the electrical signal down the length of a neuron.
Signal LOSS per 100 feet.
You should receive your radio signal nationwide.
Latency of course. It is often called "ping" on multiplayer online games.
