The document provides an overview of the Indian telecom sector in 2002, including the key players and market structure at that time. There were three main types of players - state-owned companies (BSNL, MTNL), private Indian companies (Reliance Infocomm, Tata Teleservices), and foreign invested companies (Vodafone, Bharti). BSNL, MTNL and private operators like Bharti were making major investments and expanding operations. The sector was moving from a monopoly to increased competition and private sector participation under regulatory reforms, though it remained an oligopolistic market with high barriers to entry and price competition between major players.
