The country's largest mobile telecom company, Bharti Airtel, has the most congested telecom networks followed by its rival Vodafone Essar, telecom regulator Telecom regulatory authority of India (Trai) has said.
Trai, which has been monitoring this aspect on a monthly basis, said, "The result reveals that in a number of areas, the degree of congestion between the operators is alarming. In a number of cities, the level of congestion between the networks of different operators is far more than this benchmark."
It further said amongst the private service providers Bharti Airtel has the largest number ofPOIs (Point of Interconnection) having congestion (41 POIs as of September '08) followed by Vodafone (22 POIs as of September'08), Reliance Communications and Idea (19 POIs each as of September '08), Dishnet Wireless (18 POIs).
Trai further said in as many as 129 places in the country, the congestion levels were way above the permissible limit during the quarter ended September'08. However, the number of POIs having congestion has decreased from 156 in June, 2008, to 129 in September, 2008.
Network congestion leads to call drops and deterioration in voice quality. The regulator tracks this by evaluating the congestion levels at the Points of Interconnection (PoI), which are the places where mobile traffic is exchanged between the networks of different operators.
Congestion level is one of the important parameters and signifies the ease by which a customer of one network is able to communicate with a customer of another network.
