Telecommunications equipment

Smartphones are one of the most popular telecoms equipment.

Telecommunications equipment (also telecoms equipment or communications equipment) is a type of hardware which is used for the purposes of telecommunications. Since the 1990s the boundary between telecoms equipment and IT hardware has become blurred as a result of the growth of the internet and its increasing role in the transfer of telecoms data.^[1][2]

Types

Telecommunications equipment can be broadly broken down into the following categories:^[3]

• Public switching equipment
  • Analogue switches
  • Digital switches
    • Voice over IP switches
    • Virtual reality (VR)
• Transmission equipment
  • Transmission lines
    • Optical fiber
    • Local loops
  • Base transceiver stations
  • Free-space optical communication
    • Laser communication in space
  • Multiplexers
  • Communications satellites
• Customer premises equipment (CPE)
  • Customer office terminal
  • Private switches
  • Local area networks (LANs)
  • Modems
  • Mobile phones
  • Landline telephones
  • Answering machines
  • Teleprinters
  • Fax machines
  • Pagers
  • Routers
  • Wireless devices

Semiconductors

Most of the essential elements of modern telecommunication are built from MOSFETs (metal–oxide–semiconductor field-effect transistors), including mobile devices, transceivers, base station modules, routers, RF power amplifiers,^[4] microprocessors, memory chips, and telecommunication circuits.^[5] As of 2005, telecommunications equipment account for 16.5% of the annual microprocessor market.^[6]
