Why is uplink frequency higher than downlink frequency?
Why is the uplink frequency higher than the downlink frequency in satellite communication?
What are frequency bands in satellite communication? What is the highest radio frequency ever used for communications? How do satellite communications work? Why is communication on radio waves costly? What is the highest transmission frequency ever recorded? What is radio frequency interference? Where exactly inside the antenna can be the cause of radio frequency propagation? What is radio frequency? What is radio amplitude modulation? 610mhz626mhz658mhz706mhz…whats the next mhz frequency? Based on satellite cable receiver What are the advantages of frequency modulation? Why do we define bandwidth as range between frequencies corresponding to half power point and not any other point? Is that point special? What is the advantage of frequency modulation? How can the speed of data transmission be increased? What are the differences between the radio antenna and the antenna of the wireless router? What are the differences between AM and FM radio frequencies? Why do low frequency signals attenuate slowly as compared to a high frequency signal? How do satellites work in communications? What is frequency modulation? How do we get a frequency modulated signal from a carrier signal? What happens if you modulate a radio signal at radio frequency? What are the frequency bands for mobile communications supported in the UK? Why do we need carrier waves of very high frequency in modulation of signals? Does a cell phone transmit to a cell tower then to a satellite or straight to a satellite? What is the relationship between frequency and wavelength? What is meant by radio frequency waves? How is frequency shared by different telecom operators? What causes frequencies to get absorbed rather than scattered in the atmosphere or vice versa? If blue light is scattered by nitrogen and oxygen in the atmosphere then why high frequency satellite signals are not scattered in the same way? Is it true that WiFi router antennas have caps that prevent the signal from being broadcast in the direction the antenna is pointing? Why signals with same frequency interfere and with different frequency don't? Why is EarthLink so slow?
