Problem statement:

Radios have a age old history they were once integral part of human

life arrival of television threw radios out of our life, but now once

again radio have gained popularity and this time radio has

entered our life with a fleet of new features.

Radio today is not just source of entertainment but has come a long

way to become a useful tool of information Sharing, with the

arrival of community and campus radios, Radios have change

their face and use, Now radio is used for announcements,

information, notice and verity of training programs.

Yet the problem is every one cannot carry a radio in their pockets

though many mobiles have radio integrated in them again not many

have it. Therefore there is a need of as system wherein multiple day-

to-day devices can be used as radio.

Possible solution


3/6

To add to this transforming technology we propose to design an

Intranet campus radio which will again be a breakthrough in

communication technology.

The proposed project is building a radio transmission system for a

campus where in what ever relayed from our radio station

through a software can be heard on software radio on the

computer in the LAN or it can be heard on the computers in WI-

FI network, This project takes audio from the microphone and

computer software and will output the data to a specified port to

the radio software program and then output the sound to the

Radio.

Through a routing mechanism the signals will also be transmitted via

FM transmitter so that conventional FM radio users can also

listen to the radio.

Protocols usedA socket is a software endpoint that establishes bidirectional

communication between a server program and one or more client

programs. The socket associates the server program with a specific

hardware port on the machine where it runs so any client program

anywhere in the network with a socket associated with that same port

can communicate with the server program.

A server program typically provides resources to a network of client

programs. Client programs send requests to the server program, and

the server program responds to the request.


4/6

One way to handle requests from more than one client is to make the

server program multi-threaded. A multi-threaded server creates a

thread for each communication it accepts from a client. A thread is a

sequence of instructions that run independently of the program and of

any other threads.

Using threads, a multi-threaded server program can accept a

connection from a client, start a thread for that communication, and

continue listening for requests from other clients.

Future enhancement

This project is already an enhancement to existing system, right now

there is nothing which can be enhanced but in future If Bluetooth

becomes more advanced then devices with Bluetooth connectivity can

also be included in this project, further the range of Wi-Fi wireless

network can also be increased.

Advantages


6/6

This project will be a boon for college students if implemented in the

college, personality development, exam tips, interview preparation,

announcements etc can be continuously relayed and students in the

campus can benefit by availing this service through various devices.

Disadvantages

The only disadvantage is the users will not be able to avail the service

if they are out side the Wi-Fi or FM range.
