Question

How did satellite communication impact the undersea cable telephony business? Was it complementary or competitive?

Answer 1

These 2 kinds of communication have to be compelled to be thought of along since early satellite broadcasting was involved with manufacturing signals to be distributed on a cable television service. These were notably prevailing within us by the Nineteen Seventies in localities wherever a satellite/ cable television service might give higher reception of, and larger diversity than, terrestrial channels

There is the link between satellite and cable systems within us was created by HBO, a cable provider, WHO used a satellite to transmit a flick service to cable operators for distribution. Hotels and bars within the US and North American country were presently construction satellite receiving instrumentation so as to capture the signal while not subscribing, and therefore the marketplace for direct broadcasting by satellite had been established.

From the middle Nineteen Seventies it'd be an extra decade before the technology was powerful enough, and therefore the receivers low cost enough, for wholesale domestic use, however by the late Eighties this had become a reality, not solely within the us however throughout Western Europe additionally with the launch of the European Astra satellite. By the middle, Nineteen Nineties television system was on the market throughout most of the globe, either distributed via cable or DBS. 10 years on, the immediacy of tv from, and in, nearly any a part of the globe is taken mostly with no consideration.

Cable, each area unit Cable. each carries signals, however, the submarine cable will carry power and signal.

More serious note.

Just totally different sort of technologies to send info, across distances.

Submarine cable:
pros
- sometimes will carry a lot of info and in some instances power.

- the weather seldom has an effect on the transmission capabilities of those cables.

Cons
- takes a protracted time to get the physical cable, and meet up with the “opposite” finish.

- susceptible to physical injury, such a anchors dragging or hit the cable.

- repairs take time, as somebody (lots of individuals and typically with a ship) got to physically raise up the cable to repair it.

Satellite,
pros
- will bridge distance faster, than submarine cable, because the transmission and receiving station want solely see the satellite to change information transfer.

cons
- however, sometimes have a slower rate.

- weather will have an effect on the transmission rate.

- repairs arduous to implement for the satellite, sometimes transaction another service supplier satellite is quicker and cheaper.

Which technology to use, depends on what's the requirement and therefore the value.
