Data Communication and Net-Centric Computing (COSC 2061)
Assignment 2
Student Name: Weibin Zhong
Number: s3503887
Introduction
This report is identifying what are FDMA, TDMA and CDMA and how to maintain the communication seamlessly and the roaming service as well as the cost of roaming service. Furthermore, the 1G, 2G, 3G and 4G generations will be discussed. Finally, the potential issues or risks while using the mobile wireless will be discussed.
1. the technical details of FDMA, TDMA and CDMA
(1) FDMA
Frequency Division Multiple Access (FDMA) bandwidth is divided into narrow frequency slots and is use to allocate a unique frequency band or channel that a user is free to transmit or receive all the time over the shared …show more content…
The issues and possible risks in using wireless communication.
There are few security risks occurring in mobile and wireless user:
A. Intrusion - networks are more open to intruder access unless protective measures (such as passwords, encryption and identifier disabling) are adopted and this may result in a greater susceptibility to theft or misuse of information contained on networks, unauthorized destruction or modification of data, and abuse of network capacity
B. Leeching - bandwidth can be used by intruders at the expense of legitimate businesses and users
C. Exploitation - network access can be misused to launch denial of service (DoS) attacks against third parties, transmit illicit material such as child pornography, or engage in other criminal activities. [10]
5. Conclusion:
The report introduced three wireless generations which have been using for the last few decades. The wireless technologies have developed rapidly. In addition, I presented information about FDMA, CDMA and TDMA. However, I known that we need to keep our personal security information privacy when we are using
