State-owned BSNL is preparing to conduct trials for 4G network technology, and it is being known that major technology companies such as Tata Consultancy Services (TCS), Tech Mahindra, HFCL and L&T are shortlisted for conducting the trial to test the telecom service provider’s local equipment. As per a Financial Express report, the trials will be conducted at five locations to test the equipment. TCS, which has partnered with C-DoT for core network and Tejas and Altiostar for radio equipment, will conduct the trials at Chandigarh. Also, the report stated that Tech Mahindra will conduct the trials with core equipment of Pertsol and the radio network of Sterlite and Altiostar at Pune. Similarly, HFCL will conduct trials with Pertsol and Mavenir at Chennai and L&T, too, will do along with Pertsol and Mavenir at Bangalore. State-run ITI will conduct trials at Ambala. These companies are given four months to conduct the trials and provide proof of their 4G network technology. Accordingly, a suitable company will be selected for rolling out 4G network technology for BSNL. The trial is required as BSNL is mandated to use equipment from local firms for its 4G network.
