4.73 per cent of calls get dropped in India, globally its 3% @telecom_india

The report by  RedMango Analytics says 59.1 per cent of call drop in India is due to poor quality and 36.9 per  due to network faults. Poor quality can be defined as high interference in the radio signal from the mobile phone to the tower and vice versa.According to the report, higher-priced smartphones worth Rs 30,000 and above experienced lowest call drops followed by mid-range smartphones. The survey was carried out across 20 cities across India, including Mumbai, Kolkata, Bengaluru and Jammu.Most operators have call drop rates higher than the 2% limit prescribed by TRAI.

Marconi Prize winer India-born engineer-scientist and Stanford University Professor Emeritus Dr.Arogyaswami Joseph Paulraj finds system engineering is a major reason behind the currernt high percentage of call drops in India.Recently he was in Bangalore to deliver the IEEE-VITM lecture on 'Mobile Communications-Past and Future.' It may be noted, that Dr. Paulraj has made profound contributions in building  MIMO technology which every wifi router and 4G phone uses today.
