As part of xG-Force lab's continuing journey in building the ecosystem that brings the best together for Tata Elxsi’s customers, enterprises and CSPs can validate, test, and deploy these integrated 4G/5G solutions at scale, reducing time-to-market while ensuring performance, reliability, and security. It addresses critical use cases across industries such as manufacturing, logistics, utilities, healthcare, transportation, and smart campuses.

Through xG-Force LaaS, Tata Elxsi will develop and integrate 5G applications with its innovative platforms—Neuron for autonomous networks, TETHER for connected vehicles, TEngage for digital health, and TEDAx for big data engineering—to bring solutions in AI, next-gen communications and advanced technologies.

At the heart of the solution is Druid’s field-tested mature Raemis™ core network platform which can be deployed as a completely standalone 4G/5G core network at any critical location requiring secure, high-quality, private wireless coverage. With its built-in IMS layer, Raemis enables high-quality voice services and can be integrated via standard interfaces to MCC platforms supporting PTT, broadcast messaging and other advanced features. Beyond its flexible deployment options and multimedia capabilities, Raemis offers ease of installation & provisioning as well as centralized control. 

The joint solution enables enterprises to unlock Industry 4.0 applications including automotive, healthcare, IoT, AR/VR, digital twin, and mission-critical communications with guaranteed Quality of Service (QoS).

With Lab-as-a-Service, Tata Elxsi is enabling enterprises to de-risk and accelerate their 5G journey by testing, validating, and deploying future-ready networks. “Our collaboration with Druid Software ensures enterprises get the best of 5G core and IMS in an integrated, standards-compliant environment, said Priya S. Kumar — Head, Media & Communications, Tata Elxsi.

By combining our mature multigenerational 4G/5G core platform, with a built-in IMS layer, and Tata Elxsi’s Lab-as-a-Service, enterprises gain the confidence to deploy next-generation connectivity tailored for their most demanding use cases, said Sumit Gehani, VP of Sales, Druid Software.

IIT Hyderabad and WiSig Network’s 5G Innovations Attain Mainstream Paving the Way for 6G at 3GPP Meetings at Prague

• RAN #108, Prague (Jun 2025): Consortium backs India’s π/2-BPSK extension for stronger 5G coverage and to uplink-heavy apps (HD video, XR, on-device AI) while seeding 6G.
• From Lab to Global Standard: Developed at IIT Hyderabad in 2014 → National program → 3GPP 5G Rel-17 feature now used by operators and vendors worldwide.
• Team India + Global Allies: Led by Prof. Kiran Kuchi, Department of Electrical Engineering, IIT Hyderabad, with support from Qualcomm, Apple, Ericsson, Nokia, Samsung, MediaTek, DOCOMO, AT&T, Reliance Jio, Thales, and others—backed by DoT, MeitY, DST, and TSDSI.
• Next Stop 6G: IITH & WiSig are already advancing OTFDM and Structural MIMO tech in the new 6G Study Item to power future networks and devices.

At 3GPP TSG RAN #108 in Prague, a global  consortium proposed extending India’s π/2-BPSK uplink waveform to further strengthen 5G coverage and unlock uplink-intensive services—such as high-definition video, immersive XR, and on-device AI—while paving the way for 6G.

Originating in 2014 at IIT Hyderabad as a single-institute effort, the waveform progressed into a national program with leading industry and academic partners, became a 3GPP Release 17 standard, and is now a mainstream 5G feature adopted by operators and vendors worldwide.

Prof. Kiran Kuchi, Department of Electrical Engineering, IIT Hyderabad, the driving force behind this success and founder of IIT Hyderabad spin-out WiSig Networks, remarked, “India’s coverage-enhancement technology—created with fellow Indian institutes and global collaborators including Qualcomm, Apple, Ericsson, Nokia, Samsung, MediaTek, DOCOMO, AT&T, Reliance Jio, Thales, and others—has become an integral part of the global standard.”

We gratefully acknowledge the efforts of various organizations of Government of India, i.e. the Department of Telecommunications (DOT), the Ministry of Electronics and Information Technology (MeitY), the Department of Science and Technology (DST), and the Standards Development Organisation, Telecommunications Standards Development Society, India (TSDSI) for their steadfast support in this regard.

Prof. B S Murty, Director of IIT Hyderabad, added, “IIT Hyderabad is committed to breakthrough research in the field of Wireless Communications that translates into globally adopted patents and products, propelling India toward Viksit Bharat.”

As the 6G era dawns, IIT Hyderabad and WiSig Networks are already advancing technologies such as the OTFDM waveform and Structural MIMO within the newly approved 6G Study Item. Together with Indian and global partners, we will continue to imagine, invent, and deliver the next generation of communication technologies, networks, and devices.
