Telecommunications equipment (alsotelecoms equipment orcommunications equipment) is a type of hardware which is used for the purposes oftelecommunications. 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]
Telecommunications equipment can be broadly broken down into the following categories:[3]
Most of the essential elements of modern telecommunication are built fromMOSFETs (metal–oxide–semiconductor field-effect transistors), includingmobile devices,transceivers,base station modules,routers,RF power amplifiers,[4]microprocessors,memory chips, andtelecommunication circuits.[5] As of 2005, telecommunications equipment account for 16.5% of the annualmicroprocessor market.[6]
