MIT4033- Wireless and Mobile Communication
Qus:1 Write a short note on different generations of
wireless network.
Answer: The
wireless communication network has undergone lot of evolution from the day of
its introduction. To study these history and evolution it is categories as
different generations. Every generation carries the features that are available
and supported by electronic devices of
Qus:2 Describe the concepts of followings:
(a) cell splitting
(b) frequency reuse in cellular networks
Answer: (a)cell splitting
This
method to increase the capacity of users is used in a network when the size of
each cell is same and the density of users on different. If the size of the
cell is large, then the transmitted radio wave must be of higher energy (called
strength of the signal) to reach the border of the cell
Qus:3 Describe BSC and MSC protocols.
Answer: BSC protocols Once
the information is communicated from the BTS to the BSC, the Abisinterface is
used to communicate further the information between the BT Sand BSC. At this
level, the radio resources at the lower portion of Layer 3are handled by the
Base Transceiver Station Management (BTSM) protocol rather than the RR
protocol. The BTSM layer acts as a
Qus:4 List and explain the different methods of
speech coding.
Answer: There
are three different speech coding methods. They are:
a)
Waveform coding
b)
Source coding and
c)
Hybrid coding
a) Waveform coding
This
approximates the speech signal as waveform. In this class of coding, the
objective is to minimize a criterion which measures the dissimilarity between
the original and the reconstructed
Qus:5 Explain the following with context to GSM
security:
a) A5 algorithm for encryption
b) A8 algorithm for key generation
Answer: GSM
encryption is the means by which phone conversations on networks using GSM are
scrambled, such that they cannot be descrambled and intercepted by others.

Qus:6What is Wimax? Discuss it’s architecture with suitable
diagram.
Answer: WiMAX,
which stands for worldwide Interoperability for Microwave Access, was designed
by the WiMAX forum and standardized as IEEE 802.16.
WiMAX
are being classified as a metropolitan area network (MAN). WiMAX is a
telecommunications protocol that provides fixed and mobile Internet access. Two
version of WiMAX are as
