Dishnet Wireless Ltd, a part of Aircel group that offers GSM mobile services in northern and eastern states, emerged as the most congested mobile network in April-June this year, telecom regulator TRAI said today.
As per the analysis by the Telecom Regulatory Authority of India, Dishnet Wireless had 20 congested points of interconnection (PoIs) in June. A PoI is a geographical location where two networks interconnect and exchange traffic.
Against this, BSNL had eight congested PoIs, followed by Vodafone and Aircel with six and three such PoIs respectively.
TRAI says the benchmark for the level of congestion at PoIs between various networks is kept at less than 0.5 per cent. This means, of every 200 calls between two operators, only one call should face a problem.
This also reflects as to how effective is the inter-connection between two networks.
During the said period, the mobile subscriber base has increased from 391.76 million in March 2009 to 427.29 million in June 2009, while the number of PoIs with congestion has decreased from 76 in March to 42 in June 2009.
The telecom circles or states being most affected due to congestion are Bihar with 9 PoIs, followed by Uttar Pradesh (east) with eight PoIs and Orissa with six POIs, TRAI said.
