Why does upload and download have different frequencies?

The download and upload streams operate on two different frequencies above the voice frequency, which being fairly high, decay pretty quickly over any distance. There’s not much room for more bandwidth in copper wires, so keeping the lines biased toward download is probably for the best.

What is the relationship between the satellite uplink frequency and downlink frequency?

Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.

What is difference between uplink and downlink?

In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite.

Why must a satellite communication have distinct uplink and downlink frequencies explain?

In order to avoid interference, the satellite must have distinct uplink and downlink frequencies. The satellite receives the signal on one frequency and it transmits on another frequency, the reason is to avoid the interference of signals. To obtain clear transmission, the frequency must be distinct between them.

Why is download faster than upload?

This is usually normal, because most high-speed Internet connections, including cable modems and DSL, are asymmetric — they are designed to provide much better speed for downloading than uploading. So if your upload speed appears to be slower than your download speed, this is probably expected.

Why uplink frequencies are always less than downlink frequencies?

It say basically the power at ground stations is more as compared to power available at satellites.So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.

Why are uplink and downlink frequency not the same in satellite Mcq?

3. The downlink frequency is lower than the uplink frequency. Explanation: The original signal being transmitted from the earth station to the satellite is called the uplink, and the re-transmitted signal from the satellite to the receiving stations is called the downlink.

What is the uplink frequency?

The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite. The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver.

What is the difference between uplink and downlink frequency?

Why download speed is slow and upload speed is high?

The main culprit of slow upload speeds, especially when compared to your download speeds, is the internet plan itself. If you already have internet service, you may want to consider upgrading to a faster plan. You’ll likely not only get faster upload speeds but also a nice boost in download speeds.

Why download speed is slow but Internet fast?

Some may be much slower, not because your internet is slow, but because the server you’re downloading the file from is busy or slow. You can back this up by heading to a site like speedtest.net, which measures your internet speed in megabits, just like your internet provider does.

Why is the uplink frequency higher than the downlink frequency?

It say basically the power at ground stations is more as compared to power available at satellites.So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.

Why do we use a lower frequency as downlink in satellites?

The attenuation faced by a high frequency wave is more than a low frequency wave. Higher frequency means higher energy and it’s need more power to transmit. But power in satellite is limited with respect to ground station. Thats why we use lower frequency as downlink so that it’s require less power and face low attenuation to transmit.

Why does BTS have to transmit on uplink using higher frequency?

So lets suppose that BTS (as in case of GSM) transmits using low frequency on the downlink. So, that means lower attenuation. Hence, data is received as it should be (without attenuation). So, MS (mobile) has to transmit on uplink using higher freq. in order to avoid interference. But high freq. means higher attenuation.

What is the range of uplink and downlink speeds for Deep Space?

For deep space, Sband uplink is at 2.1–2.120 GHz (correction – near earth is 2.025–2.1, deep space is 2.1–2.12), Downlink at 2.2–2.3. Xband uplink is at 7.15 GHz, downlink at 8.4-8.45 GHz. Ka-band is upside down from that.
