Broadband Modem is a digital equipment used for high speed internet services. They are used by both DSL or cable internet services and will be supplied by your internet service providers. They connect to internet at high speeds. This has come as the erstwhile internet connectivity as using dial up proved to be slow and also impaired the use of a telephone.
In a basic transmission model, information is transmitted in a single channel as against in broadband model of transmission, wherein a wider transmission channel is used facilitating transmission of multiple traffic and signal types, etc such as in computer networks, telecom, video, and computer networks where broadband is being used extensively.
Broadband Modem has come into existence as an answer and solution to the problem of speed at which one can access the internet, browse information and download data. With the previous method of connecting to internet, the dial up, the time to download a song was almost close to 5 minutes and a movie of 700 MB was about 28 hours. This was proving time consuming and therefore a need to devise a high speed internet access method has evolved.
Broadband in internet service is defined as transmission channels that can support the carriage of higher bit rates than 1.5 to 2 bits which were considered primary transmission rates. With it's ability to help you browse and access at a very high speed, Broadband came into existence in 1997, but gained popularity only in 2001. And by 2004 most families were connected to internet using broadband networks.
Broadband Modem are being used in a variety of services as they help speedy transmission of signals across different traffic. The three most common types of broadband available are: cable modem, wherein the data is transmitted in a neighborhood over a cable, and if all the users are connected, the speed decreases because of the heavy traffic. DSL or digital subscriber line is the next best alternative that provides speeds at a higher rate than cable modem. In a DSL model unused frequencies are used in the existing telephone connection. Satellite is the fastest connection model using broadband system, combined with a satellite service and an antenna provides for faster data access.
