Define the following terms and state their usage.
The near-far problem is a condition in which a receiver captures a strong signal and thereby makes it impossible for the receiver to detect a weaker signal.
Write short note on Call setup of GSM network for mobile-to-mobile call.
GSM (Global System for Mobile Communications), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by wireless phones.
What is spread spectrum technique? Name two standard spread spectrum techniques and state the main difference in their principles of operation.
Spread-spectrum techniques are methods by which an electrical, electromagnetic, or acoustic signal generated with a particular bandwidth is deliberately spread in the frequency domain,
What are tunnelling and encapsulation in the context of mobile IP?
The encapsulation process creates a logical construct called a tunnel between the device that encapsulates and the one that decapsulates.
Draw the system architecture of GSM and explain the functionality of HLR and VLR. Why is the cell structure supposed to be a hexagon in a mobile network?
The GSM network can be divided into five main groups: 1) Mobile station(MS): It include mobile equipment(ME) and the subscriber identity module(SIM)
Explain the concept of frequency reuse in cellular systems.
Frequency reuse is the process of using the same radio frequencies on radio transmitter sites within a geographic area that are separated by sufficient distance to cause minimal interference with each other.
What do you mean by co-channel interference and system capacity?
Co channel interference is the interference between two access points(APs) or base stations operating at the same frequency.
Discuss the three different mechanisms to improve the cell capacity and coverage area in a cellular system.
When a cells capacity is no longer able to provide an acceptable QOS, several methods can be to increase system capacity.in areas where there is poor reception of radio signals, the use of repeaters can improve radio coverage
Describe the architecture of a 3G network. What are the various services associated with a 3G network?
The 3G system consists of two main parts: the User Equipment (UE) and the UMTS Terrestrial Radio Access Network (UTRAN). The UE is the mobile phone and the UTRAN is the base station and the network intelligence.
Define packet switching and circuit switching. What is MANET?
In packet switched network, the message is divided into packets of fixed or variable size. In packet switching, there is no allocation for a packet and there is no scheduled processing time for each packet. Resources are allocated on demand.
