EP 601 DATA COMMUNICATION

BASEBAND AND BROADBAND

TRANSMISSION TECHNIQUES The transmission speed of a system is

a rate of transmission bits per second.

The large bandwidth allows higher speed and load of high-bits data communication.

There are two methods of delivery techniques :->

Baseband Broadband

BASEBAND To provide a single channel for all the

bandwidth where the bandwidth is not divided into channels.

Can be used to carry different types of information by using TDM techniques where is the time slots are used in rotation.

The digital transmission does not require a modem , however for voice it require a modem.

Not only a big bandwidth can used a baseband cable between the PC .

Maximum data for Baseband transmission is (10Mbps or more).

ADVANTAGES AND DISADVANTAGES

ADVANTAGES :-> Low cost Ease of installation and maintenance

High rates

DISADVANTAGES :-> Limited distances Data and voice only

BROADBAND Bandwidth this divided into several

channels. Provided sub channel communication

and allow the transfer of information in parallel.

Broadband is using FDM techniques because each channels carrying a different frequency. FDM is commonly known as radio frequency (RF) modem.

Need a big bandwidth , so that we can put 20 to 30 channels per cable.

ADVANTAGES AND DISADVANTAGES ADVANTAGES :->

Data, voice and video can be accomplished on broadband channel.

Greater distances. Greater bandwidth.

DISADVANTAGES :-> Cable Design. Alignment and maintenance.  High cost, requires modems. Lack of well developed standards.

DIFFERENCE BETWEEN BASEBAND AND BROADBAND

Baseband BroadbandDigital signals are used. Analog signals are used.

Frequency division multiplexing is not possible.

Frequency division multiplexing is possible.

Baseband is bi-directional transmission.

Transmission of data is unidirectional.

Short distance signal travelling.

Signal travelling distance is long.

Entire bandwidth of the cable is consumed by a single signal in a baseband transmission.

The signals are sent on multiple frequencies and allow all the multiple signals are sent simultaneously in broadband transmission. 

QUESTION1) What is baseband ?

(a) Is a topology to connect all nodes in a form of circular chain. (b) Is a bandwidth to divide other channels (c) Is to provide a single channel for all bandwidth where the bandwidth is not divided into channels
