Telecom Regulatory Authority of India (TRAI) is an independent regulatory body established by the Telecom Regulatory Authority of India Act 1997 to oversee the telecommunications industry in India.
TRAI is charged with ensuring the orderly growth of the telecom sector while protecting the interests of both telecom service providers and consumers. It encourages technological improvements and makes recommendations for how providers can improve efficiency and technical compatibility. To that end, TRAI establishes standards for quality of service (QoS) and supervises how service providers share revenue. TRAI also conducts periodical surveys to ensure that telecom service providers are acting in the best interest of consumers and are operating in compliance with universal service obligations.
