Today, i had my project external and have been asked a few questions. I answered them but am not sure about them. The questions are -
It is known that GSM works in the frequency range 800/900 MHz. Now does that mean the tower transmits at 800 MHz and the mobile receives the same and while calling does the mobile transmits at 800 MHz and the tower receives the same. Also, when we are moving, and hand off takes place, does one tower communicates with the neighbouring tower for this hand off action. If yes, then does it also communicates in the same frequency of 800 MHz.
Can someone explain these to me,.please,.thanks a lot,..
