1 How “wireless and mobile are two different concepts”. Explain any two applications that use wireless networks and mobile communications.

Answer: TDMA is the access method used by the Electronics Industry Alliance and the Telecommunications Industry Association for Interim Standard 54 (IS-54) and Interim Standard 136 (IS-136). Using TDMA, a narrow band that is 30 kHz wide and 6.7 milliseconds long is split time-wise into three time slots. Narrow band means channels in the traditional sense. Each

2 What is modulation? Briefly explain Amplitude Modulation (AM), Frequency Modulation (FM) & Phase modulation (PM).

Answer: Modulation

The modulation technique used on the radio channel is Gaussian Minimum Shift Keying (GMSK). GMSK belongs to a family of continuous-phase modulation procedures, which have the special advantages of a narrow transmitter power spectrum with low adjacent channel interference, on the

3 Explain the GSM TDMA frame with the help of frame structure.

Answer: There are five kinds of burst GSM TDMA frame:

Normal Burst (NB): The NB is used to transmit information on traffic and control (except RACH) channels. The individual bursts are separated from each other by guard periods during which no bits are transmitted. At the start and end of each burst are three tail bits which are always set to logical ‘0’. These bits fill a short time span during which transmitter power

4. Explain Source Coding and Speech Processing.

Answer:

Source Coding and Speech Processing

Source coding reduces redundancy in the speech signal and thus results in signal compression, which means that a significantly lower bit rate is achieved than needed by the original speech signal. The speech coder/decoder is the central part of the GSM speech processing 

5. Write short notes on Cluster-based routing protocol.

Answer:

In Cluster Based Routing protocol (CBRP) [Jiang99], the nodes are divided into clusters. To form the cluster the following algorithm is used. When a node comes up, it enters the "undecided" state, starts a timer and broadcasts a Hello message. When a cluster-head gets this hello message

6. Mention and explain different Table-Driven Routing Protocols.

Answer:

Table-driven Routing Protocols: Keeps routing tables at each node, which is updated periodically, and the routing procedure is based on this data.

One routing-table driven method is the next-hop model. In this model, each node keeps the best next-hop node

2 What is Message and Packet switching?

Answer: Message switching

Message switching was the precursor of packet switching, where messages were routed in their entirety and one hop at a time. It was first introduced by Leonard Kleinrock in 1961. Message switching systems are nowadays mostly implemented over packet-switched or circuit-switched data networks.

Qus:3 What is Stop-and-Wait Automatic Repeat Request? Briefly explain.

Answer:

Stop-and-Wait Automatic Repeat Request:

This protocol adds a simple error control mechanism to the stop-and-wait protocol. To detect and correct corrupted frames, we need to add redundancy bits to our data frame. When the frame arrives at the receiver site, it is checked and if it is corrupted, it is silently discarded. The

3 Find the Taylors expansion of f(x) = Sin x at x = 0.

Answer: Taylor's Theorem is an extension of the Mean value theorem.

Though Taylor's Theorem has applications in numerical methods, inequalities and local maxima and minima, it basically deals with approximation of functions by polynomials.
