An implication of defining telecommunications broadly is that every layer involved in communication at a distance becomes, at least partially, part of the telecommunications industry. The broad range and large number of companies that contribute to the telecommunications industry are evident in the following list of examples:
Networking service providers across the Internet and the PSTN, wireless carriers, and cable operators. Examples include AT&T, Comcast, Verizon, and DirecTV.
Communications equipment suppliers that are the primary suppliers to service providers. Examples include Cisco, Lucent, and Motorola.
Networking equipment suppliers selling products to end-user organizations and individuals. Examples include Cisco’s Linksys division and Hewlett-Packard (local area networking products).
Semiconductor manufacturers, especially those supplying system-on-a-chip solutions for the telecommunications industry. Examples include Texas Instruments, Qualcomm, Broadcom, and STMicroelectronics.
Suppliers of operating systems that include a networking stack. Microsoft is an example.
Software suppliers, especially those selling infrastructure and applications incorporating or based on real-time media. Examples include IBM, RealNetworks (streaming media), and BEA (application servers).
Utility or on-demand service providers selling real-time communications-oriented applications. Examples include AOL and Microsoft (instant messaging) and WebEx (online meetings).
Consumer electronics suppliers with communications-oriented customer-premises equipment and handheld appliances. Examples include Motorola and Nokia (cell phones), Research in Motion (handheld e-mail appliances), Polycom (videoconferencing terminals), Microsoft and Sony (networked video games), and Panasonic (televisions).
What is striking about this list is how broad and inclusive it is. Even though many of these firms do not specialize solely in telecommunications, it is now quite common for firms in thelarger domain of information technology to offer telecommunications products or to incorporate telecommunications capability into an increasing share of their products.
