WIND ranks behind which Rome-based telecommunications company?
Telecom Italia Telecom Italia is an Italian telecommunications company headquartered in Rome, which provides telephony services, mobile services, and DSL data services. It was founded in 1994 by the merger of several state-owned telecommunications companies, the most important of which was Società Italiana per l'Esercizio Telefonico p.A., (known as "SIP", from the earlier "Società Idroelettrica Piemontese"), the former state monopoly telephone operator in Italy.
CSELT Centro Studi e Laboratori Telecomunicazioni (CSELT) was an Italian research center for Telecommunication based in Torino, the biggest in Italy and one of the most important in Europe. It played a big role internationally especially in the standardization of protocols and technologies in telecommunication: perhaps the most widely well known is the standardization of mp3. It was active from 1964 to 2001, initially as a part of the Istituto per la Ricostruzione Industriale-STET – Società Finanziaria Telefonica group, the major conglomerate of Italian public Industries in the 1960s and 1970s; it later became part of Telecom Italia Group. In 2001 was renamed TILAB as part of Telecom Italia Group.
