Study Notes

Overview of Broadband Access Technology

The main objective of this chapter is to understand broadband, its need, various technologies, and broadband network.
The evolution of computer networking and packet switching has led to a new era of integrated communication in the telecom world.

Definition of Broadband

Broadband refers to high-speed digital Internet access.
It indicates a means of connectivity at a high or broad bandwidth.
Various definitions of broadband include:
- A term for evolving digital technologies that provide customers a high-speed data network connection.
- A signal-switched facility offering integrated access to voice, data, video, and interactive delivery services.
- An advanced telecommunications capability defined by the Federal Communications Commission (FCC).
- Delivers services and facilities with an upstream and downstream speed of 200 Kbps or more.
- In India, Broadband connectivity is defined as an "always-on" data connection with a minimum download speed of 512 kbps.

Characteristics of Broadband

Broadband refers to greater bandwidth or transmission capacity of a medium.
Broadband technology allows for high-speed transmission of voice, video, and data over networks like the Internet.

Implementation of Broadband

The Government of India has formulated a Broadband Policy to:
- Establish a regulatory framework for the carriage and content of information in the scenario of convergence.
- Facilitate development of national infrastructure for an information-based society.
- Make available broadband interactive multimedia services to users in the public network.
- Provide high-speed data and multimedia capability using new technologies to all towns with a population greater than 2 lakhs.
- Make available Internet services at the panchayat (village) level for access to information.

Need of Broadband

The concept of socio-economy has an important role in the field of communication of data, audio, video, speech, or any other kind of application.
Service providers and customers are interested in economy with the fastest tool of communication with more throughput.
Technology divisions are shaped by geography and infrastructure.

ADSL Technology

xDSL refers collectively to all types of digital subscriber lines, including ADSL, SDSL, HDSL, and VDSL.
xDSL technology is backed by telephone companies to provide next-generation high-bandwidth services to the home and business using existing telephone cooper cabling infrastructure.
xDSL technology uses a greater range of frequencies over the telephone cable than traditional telephone services, allowing for greater bandwidth.
xDSL technology has evolved greatly over the past few years and is still in development to achieve even greater bandwidth as demand rises.
