Why up-link frequency is different from down-link?
To allow duplex operation or talk and listen at the same time.
If the energy of a wave goes up does the frequency go down?
As the energy of a wave goes up, the frequency goes UP
What happens to the frequency when the wavelength of an electromagnetic wave goes up?
As wavelength goes up, the frequency comes down.
Setting Up dial Up connection By using CDMA Wireless modem?

What happens if the frequenCy of wave and its length increase?
That is impossible. Speed of wave c = frequency f times wavelength λ. To have a constant speed, the frequency goes up and the wavelength goes down or the frequency goes down and the wavelength goes up.
In GSM which frequency uplink or downlink is greater?
The main reason of selecting a lower frequency for up-link channel in GSM is because of free space path loss. The more is the frequency the more is the loss. As mobile phones, being a battery driven device, have limitation in terms of power we should always look for lower path loss. Whereas BTS antennas can transmit the signal (in down-link channel) with a comparatively high power, which will compensate the path loss. And that is why it is chosen to have lower frequency for up-link and higher frequency for down-link in GSM standards. The same theory applies in almost all type of radio communication. NOTE: Frequency and power are independent of each other. For example you can control the transmission power of BTS antenna, which still transmits in the same frequency.
Why do CDMA phones get heated up while talking?
Calculations!!! CDMA Does lot more calculations than CDMA and Chip gets heated. its GSM rather
What are up link and down link frequencyof gps?
GPS satellites transmit on two primary frequencies; band L1 is 1.57542 GHz, and band L2 is 1.22760 GHz. The uplink frequency is restricted and/or classified information.
How do you change the frequency of a thing?
Slow it down or speed it up
Why is it not possible to increase the wavelength and frequency at the same time?
Wavelength times frequency equals speed (of the wave). Therefore, unless you also change the speed, if wavelength goes up, frequency goes down, and vice versa.Wavelength times frequency equals speed (of the wave).

What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
When talking about waves as frequency increases wavelength do what?
Wavelength and frequency are reciprocals: as one goes up the other goes down.
