List out and discuss the evolution of different generations of wireless communication.
Draw Bluetooth Protocol Architecture stack and demonstrate each protocol in details.
List out the techniques to improve coverage and channel capacity in cellular systems?
If a signal-to-interference ratio of 15 dB is required for satisfactory forward channel performance of a cellular system, what is the frequency reuse factor and cluster size that should be used for maximum capacity if the path loss exponent is (a) n = 4, (b) n = 3? Assume that there are six co-channel cells in the first tier, and all of them are at the same distance from the mobile. Use suitable approximations.
Consider a transmitter which radiates a sinusoidal carrier frequency of 1850 MHz. For a vehicle moving 60 mph, compute the received carrier frequency if the mobile is moving:
List the factors influencing small scale fading and explain the factors.
Give the equation for average large scale-path loss between the transmitter and receiver as a function of distance.
Assume a receiver is located 10 km from a 50 W transmitter. The carrier frequency is 6 GHz and free space propagation is assumed, Gt = 1 and Gr = 1. Find the power at the receiver in dbm.
A mobile is located 5 km away from a base station and uses an antenna with a gain of 2.55 dB to receive cellular radio signals. Suppose transmitted power is 1 watt, find the received power at the mobile using the 2-ray ground reflection model.
Explain various methods to increase system capacity of a cellular network.
Explain in detail about Advantages and disadvantages of Wireless Adhoc Networks.
Describe how UWB radio functions, including its characteristics, benefits, and drawbacks.
