Q:

What is the difference between C-band and Ku-band satellite transmission?

A:

The major difference between C-band and Ku-band satellite transmission involves the allocation of the frequencies. C-band is assigned to terrestrial microwave radio communications while Ku-band is allocated solely to satellite communication networks.

Because of its broader allocation, C-band frequencies can overlap with other communications. It is, however, considered more robust because it is not as affected by rain and for that reason is the frequency of choice in Africa in regions prone to torrential rain.

C-band frequencies are preferable where there are requirements for large bandwidth. Ku-band uses smaller antennas and less expensive equipment and so is the choice of smaller networks, broadcasting and two-way internet connections.

    What is the difference between infrasonic and ultrasonic waves?

    A:

    The key difference between infrasonic and ultrasonic waves is that infrasonic waves include sounds emitted at levels below frequencies of noise that can be heard by humans while ultrasonic waves are those that exceed 20 kilohertz, which is the upper limit of human noise perception. Ultrasonic waves are waves that have high amplitudes. These waves are also called micro sound, and exist primarily as longitudinal waves.

    How does satellite Internet operate?

    A:

    Satellite Internet services use a dish similar to satellite television services, but a satellite Internet dish contains a broadcast element as well as a receiving element. The dish broadcasts requests from the user's PC, which the satellite bounces to a terrestrial station and into the global Internet. When the response comes back, the data is uploaded to the satellite and downloaded to the user's system via the dish.

    What is a dual-band router?

    A:

    Dual-band routers are wireless routers that use two different radio frequencies, 2.4Ghz and 5Ghz, to handle multiple devices. A dual-band router provides coverage compatible with several communication protocols by transmitting on both bands at the same time.

    Where can you view live satellite images of your house?

    A:

    While it is possible to view live satellite images of hemispheres of the earth, it is not possible to view live satellite images of your own home or of any other specific location on earth, for that matter. Live satellite images of locations that specific are not made public because of the many security and safety hazards they would provoke. It is possible, however, to view older static satellite images of your home by visiting Google Earth at www.earth.google.com.
