1.	A spectrum of 30 MHz is allocated to a cellular system which uses two 25 KHz simplex channels to provide full duplex voice channels. What is the number of channels available per cell for 4 cell reuse factor?(a) 150 channels(b) 600 channels(c) 50 channels(d) 85 channelsI had been asked this question in examination.I'd like to ask this question from Frequency Reuse in division The Cellular Concept – System Design Fundamentals of Wireless/Mobile
Answer» Correct ANSWER is (a) 150 CHANNELS Easiest explanation: Total bandwidth is 30 MHz. And the channel bandwidth is 50 KHz/duplex channel (25KHz*2). Therefore, total available channels are 600 channels (30,000/50). For 4 cell REUSE factor, total number of channels available per cell will be 150 channels (600/4).
