Course Outcome:

After learning the course the students should be able to:

Understand mobile and wireless network systems such as 2G/3G/4G mobile

telephony/data networks,

Understand GSM and GPRS

Understand the working of wireless local area network, Bluetooth.

List of Experiments:

1) Write a program to simulate Fixed Time Division Multiplexing. Take 12 stations. Every

station has time slice of 417 microseconds. Delay should be 10ms. Every time the station

gets turn, it shows message.

2) Write a program that identifies the bluetooth devices in the wireless range.

3) Write a program that prints the signal strength of WiFi connection of the given computer.

4) Prepare a wireless ad hoc network and show its working.

5) Write a program to find hamming distance. For example Hamming distance d(v1,v2)=3 if

v1=011011,v2=110001.

6) Write a program to perform infrared communication.

7) Write a program to perform Bluetooth file transfer.

8) Develop an android app which displays “Hello, welcome to Android Lab” message.

9) Develop an android app which displays a form to get following information from user.

Username

Password

Email Address

Phone Number

Country

State

State

Gender

Interests

Birth Date

Birth Time

Form should be followed by a Button with label “Submit”. When user clicks the button, a message

should be displayed to user describing the information entered.

Utilize suitable UI controls (i.e. widgets). [When user enters country in AutoCompleteTextView,

list of states should be displayed in Spinner automatically.]

10) Using Android, Create a login Activity. It asks “username” and “password” from user. If

username and password are valid, it displays Welcome message using new activity.

11) Develop calculator Android Application.

Design based Problems (DP)/Open Ended Problem:

1) Radio connectivity is inherently poor. How to ensure data delivery without retransmission?

2) Resource manager might have allocated resources to applications. How to revoke those

resources? How to utilize available resources optimally?

Major Equipment:

ACTIVE LEARNING ASSIGNMENTS: Preparation of power-point slides, which include videos,

animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate

chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point

slides should be put up on the web-site of the College/ Institute, along with the names of the students of the

group, the name of the faculty, Department and College on the first slide. The best three works should
