Question

The frequency of an outgoing call for a cell phone?

Answer 1

The frequency of an outgoing call is different from tht of an incoming cll to avoid interference

Answer 2

Answer:

• For all cellphones there are two types of calls incoming and outgoing calls hence to discourage any kind of interference with each other both the calls must have separate frequencies.
• If there is no change in frequencies the calls will interfere and the weaker one could be swamped by the stronger one.
• Frequency division duplex or FDD is a way of separating both the frequencies such that two frequencies operate at the same time.
