tion, mobile services don't limit customers to a single location for Internet access. Along with their broadband and network offerings, carriers now offer managed services, which they use to induce existing customers to purchase expanded business packages. Some managed services include operating data centers remotely for custom- ers, developing and managing custom software applications, and consulting. Managed services are a source of increased revenues for carriers. They also cement relationships with business and commercial customers. Managed services are one way that carriers differentiate themselves from other providers, who for the most part offer the same technologies. In addition, large carriers distinguish themselves from smaller carriers by promoting their international presence. This is important for enterprises with a global infrastructure. In most areas, there are only one or two large carriers able to offer broadband on this scale. Thus, multinational organizations have fewer choices for their primary carrier than do smaller or more localized organizations. The next challenge for multinational carriers is to offer afford- able, uniform mobile services, worldwide. This is particularly true in high-growth, less-developed parts of the world such as Africa and parts of Asia and Latin America. Broadband and Wide Area Network Services A DEFINITION OF BROADBAND Broadband services are defined as high-capacity network access services able to trans- mit large amounts of voice, data, and video simultaneously. The definition of broad- band 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 high- speed wireless services, as well. See Table 5-2 for a list of broadband services used wired networks. Wireless broadband services are discussed in Chapter 7, "Mobile and Wi-Fi Networks," and Chapter 8, "Mobile Carriers Worldwide."
