"These measures have resulted in a substantial decrease in instances of dropped calls in almost all key areas in Goa under supervision of Department of Telecommunication (DoT) and TRAI, along with government's support," Rajan S Mathews Director General COAI told reporters here.
The industry body said operators have been working in service delivery, including unavailability of requisite and adequate tower infrastructure.
"More than 1,200 cell sites (cell tower) need to be added to the current total of 3,500 cell sites to facilitate efficient network quality and better connectivity for residents and as well as for tourists in Goa," he said.
Mathews highlighted several factors that are creating network problems in specific areas, which relate principally to availability of cell sites.

"More than half of the cell sites are either non- operational or have been shut down due to unfounded concerns about Electro Magnetic Fields (EMF) or delays in obtaining timely clearance from local authorities," he said.
Despite such challenges, the industry continues to undertake several measures in order to address network quality issues.
The telecom industry has stressed on the importance of support received from each state government, including Goa.
"Industry seeks partnership opportunities with state governments in order to understand major challenges facing them. It is also aiming at implementing the DoT's guidelines on tower infrastructure and EMFto ensure residents' safety.
These guidelines were framed by the DoT keeping in mind all regional concerns of tower installation and after a consultation process with State authorities," he said.
