According to the Economic Times, Indian cellco Sistema Shyam Teleservices (SSTL) aims to grab a 10% market share in the wireless sector within the next five years. The operator has reiterated its plan to have launched in all telecoms circles by mid-2010, and has confirmed it will roll out commercial services in the Delhi and Mumbai metro circles in December this year. The claims came as SSTL officially launched its CDMA-based network in Calcutta, its fourth circle of operation; it is already active in Rajasthan, Tamil Nadu and Kerala. Commenting on the plans SSTL president and CEO Vsevolod Rozanov added: ‘SSTL is targeting around 35-40 million subscribers in five years. We plan to start services in two to three new circles every quarter. Next in line are the circles of West Bengal, Bihar and Jharkhand.’ The operator has also said it plans to expand the number of base stations in operation from the 4,000 it currently has to around 20,000 by 2010, and expects to invest around USD5.5 billion in the next three to five years.
