Long Distance Communications these days is handled by Microwave Towers. The good news is that these towers can be placed large distances away from each other so large distances are covered. The bad news is the towers must be in line-of-site of each other or the signal will be lost. Hilly areas are a good example of bad line of site.

What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
What is the method of boosting a digital signal's strength?
Boosting a digital signal's strength typically involves using signal amplifiers or repeaters. Amplifiers increase the amplitude of the signal, while repeaters regenerate and retransmit the signal to extend its range. Additionally, techniques like error correction and modulation can enhance signal integrity and resilience against noise, ensuring clearer transmission over longer distances.
What is DP in welding process?
DP is not actually to do with welding it is a form of NDT which stands for non destructive testing; DP is dye-pen where a white liquid formation is placed over the weld & a normally red enhancer is then placed over the top; this then identifies surface cracks.
What is the purpose of semiconductor over XLPE?
The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
What is engine force?
pressure in cylinder over piston area = force force over stroke = work
How much force is placed over an area?
force
What is a scattered settlement?
in a scattered settlement dwellings are spaced over an extensive area. found in hilly tracks, thick forests and regions of extreme climate.
Is Norfolk Island flat or hilly?
Norfolk Island is quite hilly with the main hill being over 1,000 ft. The land slopes down to the sea and there are many cliffs on the coastline
What is scattered settlements?
In a scattered settlement dwellings are spaced over an extensive area. This type of settlement is mostly found in hilly tracts, thick forests, and regions of extreme climate.
How are 2 meDals where are they placed on female dress blues?
over the left breast pocket area........................
What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
Explain the advantages and disadvantages of repeaters?
1.It is very expensive as according to the distance the no.of repeaters can be fixed and accordingly the budget or the expenditure will increase or decrease. 2. it takes a lot of time to set a repeaters between two stations.
Is Norfolk flat or hilly?
Norfolk Island is quite hilly with the main hill being over 1,000 ft. The land slopes down to the sea and there are many cliffs on the coastline
Why do fiber-optic cable span much longer distance before requiring repeaters?
They lose less energy over distances
What was normally placed over sump?
duckboards were placed over a sump
Why is cattle-rearing important in the hilly west?
Cattle rearing is important in this area because crops cannot be grown in such hilly terrain. Livestock like cattle are much more advantageous to raise in such terrain than wheat or corn because they aren't apt to flip over on you like a tractor would on the steep hills that often exist in such topography.
Is an outside antenna required when a satellite radio is used in the house?
Not if you are in a fairly large metropolitan area where they have XM repeaters all over town. If that doesn't work well, put your antenna on a window sill. Most indoor XM antennae have a 20' cord for this purpose.
