Telcos question Trai’s call drop test results

New Delhi: Questioning regulator Trai’s drive test results showing worsening call drop situation, telecom operators on Thursday said the issue is limited to area where there are problems in installing towers. Hence the QoS results from the Drive Test 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. Given the limited coverage of these Drive Tests, the results show problems limited to the known problematic areas where the industry faces issues in obtaining cell sites.” The industry body also called report on using radio link time out technology being used for masking dropped call as misleading but did not contest finding of Trai report that telecom operator Aircel is using it beyond the levels being used by its peers. “It is also interesting to note that the big headlines regarding masking of call drops using the RLT parameter proved misleading as Trai’s own published results in the Drive Tests show only one operator out of parameter,” COAI said.
