InstructionsTotal Questions: 38Total Minutes: 38This Free Online Test or Quiz or Trivia tests your knowledge on various Channels, their types and their functionalities. These Channels are defined in GSM Architecture or Structure. Each channel has its own function or use. Most of the channels work in Air Interface between a Mobile Station and a BTS (Base Transceiver Station). You can easily clear Job Interview Questions and College exams after taking this test.
