Bharat Sanchar Nigam Limited (BSNL) is now handling around 6 petabytes (PB) of data every day<\/strong> on its indigenous 4G network, highlighting the growing usage of the state-run telecom operator\u2019s upgraded mobile infrastructure.<\/p>\n\n\n\n The figure was shared by Rajkumar Upadhyay, Chief Executive Officer of the Centre for Development of Telematics (C-DOT), as BSNL continues to expand its homegrown 4G network and attract more users.<\/p>\n\n\n\n 1.75 Lakh 4G Base Stations Deployed<\/strong><\/p>\n\n\n\n According to Upadhyay, BSNL has deployed around 1.75 lakh 4G base stations across 1 lakh sites<\/strong>. These installations are currently serving millions of 4G subscribers across the country.<\/p>\n\n\n\n BSNL has around 9.3 crore subscribers nationwide<\/strong>, although the current 4G network is serving a smaller subset of that base. The growing data traffic suggests that customers are increasingly using BSNL\u2019s 4G infrastructure for mobile internet services.<\/p>\n\n\n\n The development is particularly significant because the network is based on technology developed in India rather than relying entirely on foreign telecom equipment.<\/p>\n\n\n\n TCS, Tejas Networks and C-DOT Behind the Network<\/strong><\/p>\n\n\n\n The indigenous 4G rollout has been implemented through a TCS-led consortium<\/strong>, with Tejas Networks providing the radio access network (RAN) and C-DOT supplying the core technology.<\/p>\n\n\n\n The network has now been deployed across approximately 1 lakh new sites, marking one of India’s largest indigenous telecom technology deployments.<\/p>\n\n\n\n The government-backed approach is also intended to create a domestic ecosystem for telecom equipment and technology.<\/p>\n\n\n\n HD Voice Coming Nationwide<\/strong><\/p>\n\n\n\n C-DOT has already deployed an IP Multimedia Subsystem (IMS)<\/strong> for BSNL\u2019s 4G network, enabling high-definition voice calling.<\/p>\n\n\n\n IMS-based HD voice services are currently available in seven telecom circles and are expected to be expanded nationwide in the coming months.<\/p>\n\n\n\n The technology is also being developed with future 5G compatibility in mind, meaning software updates could allow the system to support BSNL\u2019s 5G network when it is launched.<\/p>\n\n\n\n C-DOT Tests Indigenous 5G Technology<\/strong><\/p>\n\n\n\n The next step is already underway. C-DOT\u2019s indigenous 5G RAN, developed with startup WiSig and contract manufacturer VVDN Technologies, is undergoing live testing on BSNL\u2019s network in Ambala<\/strong>.<\/p>\n\n\n\n The trials are being conducted using BSNL\u2019s spectrum in the 3.6\u20133.7 GHz band<\/strong>. C-DOT expects the current testing phase to conclude within a month.<\/p>\n\n\n\n BSNL already has a 5G non-standalone core deployed across its circles, while development of a standalone 5G core continues.<\/p>\n\n\n\n From Indian Network to Export Opportunity<\/strong><\/p>\n\n\n\n C-DOT has also transferred its 4G technology to Indian companies including ITI, Bharat Electronics Limited and Electronics Corporation of India Limited for potential manufacturing.<\/p>\n\n\n\n The larger ambition goes beyond BSNL. C-DOT says its telecom technologies could eventually be offered to other operators and international markets.<\/p>\n\n\n\n Summary:<\/strong> BSNL\u2019s indigenous 4G network is now carrying around 6 petabytes of data every day<\/strong>, supported by 1.75 lakh base stations across 1 lakh sites. The milestone reflects rising 4G usage while C-DOT simultaneously expands HD voice services and tests indigenous 5G technology, strengthening India\u2019s push for a homegrown telecom ecosystem.<\/p>\n","protected":false},"excerpt":{"rendered":" BSNL\u2019s Indigenous 4G Network Sees Rising Usage Bharat Sanchar Nigam Limited (BSNL) is now handling around 6 petabytes (PB) of data every day on its indigenous 4G network, highlighting the growing usage of the state-run telecom operator\u2019s upgraded mobile infrastructure.
