1) A spectrum of 30MHz is allocated to a wireless FDD cellular system that uses two 25KHz simplex channels to give full duplex voice and control channels, calculate the number of channels available per cell if a system uses:
i. Five-cell reuse
ii. Seven-cell reuse
iii. 10-cell reuse
2) Explain Hand off strategies in detail.
3) Write a detail note on several variations of the CSMA strategy.
4) In IS-95 CDMA system, if W=1.25MHz, R=9600bps and N=14 users
i. Compute Eb/No
ii. When no voice activity is there, calculate Eb/No for omnidirectinal antennas
iii. If voice activity = 3/8 and three sector antennas are used, calculate the total number of users per cell.
5) Write a detailed note in traffic routing in wireless networks
6) Explain the two data-only mobile services developed to provide packet radio connectivity throughout a network.
