<p>Dismissing telecom regulator Trai's results showing increasing call drops in Delhi, telecom operators on Thursday said it is limited to an area where there are problems installing towers.<br /><br /></p>.<p>"While the area of Delhi NCR is 46,208 sq km, these results are limited to a route covering 600 km only. Hence, the quality of service (QoS) results from the test drive are not strictly comparable with the standard QoS for dropped calls regularly published by Trai for the entire service area," COAI said in a statement.<br /><br />The Cellular Operators Association of India (COAI) represents telecom majors, including Bharti Airtel, Vodafone, Idea Cellular, Aircel etc.<br /><br />The Telecom Regulatory Authority of India (Trai) on Wednesday published its report on drive tests of mobile service quality in Delhi and found that "all 3G networks; 2G networks of Airtel and MTNL and CDMA network of RCom have shown degradation in performance compared to the previous drive test".<br /><br />In the latest tests, state-run telecom operator MTNL also failed on all network-based quality of service parameters.<br /><br />The industry body also called the report on using radio link time out technology being used for masking dropped call as misleading but did not contest the findings of the Trai report that telecom operator Aircel is using it beyond the levels being used by its peers.<br /><br />"It is also interesting to note that the big headlines regarding masking of call drops using the RLT (Radio Link Timeout) parameter proved misleading as Trai's own published results in the test drive show only one operator out of parameter," COAI said. <br /><br /></p>
