Question: What is the required accuracy for a User Equipment (UE) modulated carrier frequency at each antenna connector, relative to the carrier frequency received from the Node B, over a period of one timeslot?
Option 1: ±0.1 ppm (parts per million)
Option 2: ±1 ppm (parts per million)
Option 3: ±10 ppm (parts per million)
Option 4: ±100 ppm (parts per million)
Explanation: This high level of frequency accuracy (±0.1 ppm) is crucial for maintaining reliable and efficient wireless communication between the UE and the Node B in a cellular network, ensuring minimal interference and optimal use of spectrum resources. Such precision is vital for the proper functioning of modern telecommunications systems, particularly in Frequency Division Duplexing (FDD) modes where uplink and downlink transmissions occur simultaneously on different frequencies.
