The telecommunications industry delivers telephone, television, Internet, and other services to customers throughout the world. Providing the primary means of communication to virtually all businesses, households, and individuals, telecommunications firms supply an essential service to the economy. In addition to offering traditional services such as wired phone and cable TV, telecommunications companies also offer services such as cellular phone, broadband and mobile Internet, and satellite TV, among others.
Opportunities in Wireless Networking
Wireless telecommunications carriers provide telephone, Internet, data, and other services to customers through the transmission of signals over networks of radio towers. The signals are transmitted through an antenna directly to customers, who use devices, such as cell phones and mobile computers, to receive, interpret, and send information. A large component of this industry segment consists of companies that provide cellular phone service, which has grown rapidly over the past decade. Another component includes establishments that deliver mobile Internet services to individuals with Internet-enabled cellular phones and computers.

Opportunities in Fiber Optics
Telecommunications carriers are expanding their data transmission capabilities, known as "bandwidth," by replacing copper wires with fiber optic cables. Fiber optic cable, which transmits light signals along glass strands, permits faster, higher capacity transmissions than traditional copper wire. In some areas, carriers are extending fiber optic cable to residential customers, enabling them to offer cable television, video-on-demand, faster high-speed Internet, and conventional telephone communications over a single line.

Wireless telecommunications carriers are deploying several new technologies to allow faster data transmission and better Internet access in an effort to make them more competitive in a market that includes wired Internet carriers. With faster connection speeds, wireless carriers can transmit music, videos, applications, and other content that can be downloaded and played on cellular phones, giving users mobile access to large amounts of data. In addition, as use of this mobile technology increases, wireless companies continue to develop the next generation of technologies that will allow even faster data transmission.
