Technical Activities
TSDSI's active standards work programme spans 5G/6G, IoT, spectrum, security, and rural connectivity — shaping India's telecom future.
Study Groups & Working Groups
TSDSI organises its technical work through two Study Groups (SGs), each with multiple Working Groups (WGs). WGs develop Technical Reports and Technical Specifications that become TSDSI standards.
Networks
5G NR (incl. 5Gi), 6G / IMT-2030, spectrum management, O-RAN, backhaul & fronthaul, network slicing, AI/ML in RAN
Services
IoT/M2M, oneM2M alignment, Smart Cities, broadband, cybersecurity, digital identity, emergency communications
Key Technical Contributions
India's LMLC propagation model for rural 5G coverage — adopted into 3GPP 5G NR Rel. 16 and part of IMT-2020.
TSDSI submitted India's national 6G vision paper to ITU-R WP5D, contributing to the IMT-2030 Framework Recommendation.
India-specific security annexure contributed to oneM2M Release 3 standards, reflecting deployment realities in emerging markets.
Published TSDSI's position paper on Open RAN deployment for India, submitted as national input to O-RAN Alliance and 3GPP RAN3.
Contributed Indian urban and rural channel models to 3GPP TR 38.901 — used in global 5G radio design.
Transposed the full 3GPP specification suite into Indian national standards, making them accessible under Indian law.
