Q.1 Explain CDMA technique. Draw necessary diagram.
Answer: – A CDMA communication system, comprising:
- A plurality of base transceiver stations spatially distributed to communicate with mobile communication devices via radio links;
- A plurality of base station controllers, each coupled to a plurality of base transceiver stations;
- A mobile switching center connected to couple said base station controllers to a public telephone network.
- A data communication system comprising (1) a plurality of packet control function devices respectively connected to said base
Q.2 List and explain the different kinds of domains available in wireless communication.
Answer:- The most mature wireless network technology today is 802.11b, which is what we will focus on. Let’s briefly go over the IEEE 802.11b standard.
IEEE 802.11b makes use of the 2.4 GHz ISM band and provides speeds from 1 Mbps up to 11 Mbps, with the range about 1500 feet. (Although in reality, you are hard
Q.3 What do you mean by mobile operating system? Explain Symbian operating system. List the mobile operating systems which are currently popular in market.
Answer:- A mobile operating system, also referred to as mobile OS, is an operating system that operates a smartphone, tablet, PDA, or other mobile device. Modern mobile operating systems combine the features of a personal computer operating system with other features, including a touchscreen, cellular, Bluetooth, Wi-Fi, GPS mobile navigation, camera, video camera, speech recognition, voice recorder, music player, near field communication and
Q.4 Explain WAP forum and mobile wireless devices.
Answer: – Wireless Application Protocol (WAP) is a technical standard for accessing information over a mobile wireless network. A WAP browser is a web browser for mobile devices such as mobile phones that uses the protocol. Before the introduction of WAP, mobile service providers had limited opportunities to offer interactive data services, but needed interactivity to support Internet and Web applications such as:
- Email by mobile phone
- Tracking of stock-market prices
Q.5 what are the two methods of Spread Spectrum modulation? Explain in detail.
Answer:- Spread spectrum communication is the modulation method used in the current standard wireless systems such as wireless LAN, Bluetooth, ZigBee and other public-use radio. You may have heard of spread spectrum communication, but wouldn’t you like to know what it actually means?
There are two types of spread spectrum communication, direct sequence spread spectrum (DS) and frequency hopping (FH) spread spectrum. However, as a general term it’s called spread spectrum communication, but the only thing it has in common
Q.6 What is demand routing protocols? Explain cluster based routing protocols.
Answer: – A stub router can be thought of as a spoke router in a hub-and-spoke network topology—as shown in Figure 34—where the only router to which the spoke is adjacent is the hub router. In such a network topology, the IP routing information required to represent this topology is fairly simple. These stub routers commonly have a WAN connection to the hub
