5. Broadband and Wide Area Network Services > A Definition of Broadband

A Definition of Broadband

Broadband services are defined as high-capacity network access services able to transmit large amounts of voice, data, and video simultaneously. The definition of broadband is not limited to signals carried over wireline media such as fiber optics, coaxial cabling, or twisted-pair copper cabling deployed in carrier networks. It applies to highspeed wireless services, as well. See Table 5-2 for a list of broadband services used on wired networks. Wireless broadband services are discussed in Chapter 7, “Mobile and Wi-Fi Networks,” and Chapter 8, “Mobile Carriers Worldwide.”

A report commissioned by the Broadband Forum and conducted by the market analyst firm Point Topic revealed that there were a total of 484 million fixed-broadband subscribers at the end of the first quarter of 2010. The report covers only broadband access over cabling and fixed, point-to-point wireless services. China had the most subscribers at 112.6 million. The country with the second most was the United States, with 87 million subscribers. These findings were reported in a June 16, 2010 ZDNET article by Victoria Ho, titled “China Adds More Broadband Lines.”
