CEWiT

What CEWiT does

CEWiT (Centre of Excellence in Wireless Technology) is an autonomous, non-profit research society hosted at IIT Madras in Chennai, India, focused on advanced wireless communication research and technology development. Founded in 2005 as a research society of IIT Madras, CEWiT employs a team of 20+ researchers with Masters and PhD qualifications from premier Indian and international institutes, working on 4G LTE, LTE-Advanced, and 5G NR technologies spanning millimeter wave communications, Massive MIMO, Dense Networks, Cloud RAN, Coordinated Multi-Point transmission, and NB-IoT. Its technical outputs include the BWSIM (Broadband Wireless Simulator) — a 4G-Advanced/5G system-level and link-level simulation platform licensed to industry and academia — and an indigenous end-to-end 5G Testbed comprising NR PHY for User Equipment, NR Layer 2/3 stacks, 5G Core, and a RAN Emulator, developed in collaboration with seven other Indian academic and R&D institutes.

The organization's business model is grant-funded and licensing/consultancy-led rather than commercial. Primary revenue comes from Government of India grants, notably from the Ministry of Electronics & Information Technology (MeitY) — a Rs 1,224.59 Lakhs grant awarded in September 2015 for a 36-month 5G research programme — and from the Department of Telecommunications for the multi-institute 5G Testbed project (April 2018–October 2021). Secondary revenue streams include licensing of BWSIM (to 4 industry partners and 9 academic institutions), IP and algorithm licensing to industry R&D partners, industrial consultancy, and fee-based training and workshop programmes (20+ delivered on 4G/4G-Advanced/5G topics). CEWiT also plays an active role in Indian and global telecom standardization through TSDSI, 3GPP, and ITU-R, including the LMLC scenario contribution accepted into IMT2020.

CEWiT serves two principal customer segments: telecom equipment vendors, operators, and R&D organizations seeking indigenous 5G technology, simulation tools, and testbed access; and academic institutions requiring advanced wireless simulation and testbed infrastructure for research and teaching. Engagements are structured as direct collaborations with CEWiT, joint collaborations with IIT Madras, or multi-institute consortia, with pricing handled on a case-by-case basis and multi-year contract cadences. As a non-profit society, CEWiT does not pursue venture funding or public listing, and its growth is governed by alignment with India's national telecom and technology priorities rather than commercial market expansion.

It is directly comparable as an Indian academic institution with deep wireless research capabilities targeting the same national 5G/6G agenda.
• IIT Bombay: IIT Bombay is a core collaborator in the multi-institutional 5G testbed consortium alongside CEWiT and conducts 5G NR PHY, mmWave and Massive MIMO research. It is a direct peer in scope (academic wireless R&D), funding sources (DoT/MeitY grants), and target outcomes (indigenous 5G technology stack).
• IIT Delhi (Bharti School of Telecom): IIT Delhi, particularly the Bharti School of Telecom Technology and Management, is a 5G testbed consortium partner conducting wireless research and offering telecom-focused graduate programs. It is a direct peer in academic wireless R&D, talent pipeline, and government-funded 5G/6G research agenda.
• IIT Kanpur: IIT Kanpur is part of the same eight-institute 5G testbed consortium as CEWiT and runs its own wireless research programs. It is a direct peer with comparable mandate, funding mix (DoT grants), and output (academic publications, prototypes, IP).
• SAMEER (Society for Applied Microwave Electronics Engineering & Research): SAMEER is a MeitY R&D lab and a 5G testbed consortium partner contributing RF/microwave and base-station subsystem expertise. It is directly comparable to CEWiT as a government-funded Indian research society focused on telecom hardware and systems engineering.

Broad incumbents

• Nokia Bell Labs: Nokia Bell Labs is a global incumbent wireless research organization with deep work in 5G/6G NR, mmWave, and AI for RAN. It is comparable to CEWiT in core function (advanced wireless research, patents, standardization) but operates at vastly greater scale with global commercial backing.
• Ericsson Research: Ericsson Research drives global 5G NR standardization at 3GPP and conducts 6G research across RAN, AI, and network architectures. It is comparable to CEWiT in its mandate of advanced wireless research and standards contribution, but as a commercial OEM R&D arm with a global footprint.
• Qualcomm Research: Qualcomm Research is a leader in wireless chipset and modem R&D with strong 3GPP/ITU standards influence. It overlaps with CEWiT in wireless research, IP generation and standardization work, but is a fabless semiconductor company monetizing IP through chip licensing rather than licensing to telecom OEMs directly.

Emerging players

• Saankhya Labs: Saankhya Labs is an Indian wireless/satellite communications semiconductor company developing 5G NR, satellite IoT and broadcast technologies. It is comparable to CEWiT as an indigenous Indian wireless technology player, but differs in being a commercial product company licensing chips rather than a research society.

Regional players

• Tejas Networks: Tejas Networks is an Indian telecom equipment vendor designing indigenous optical and wireless (4G/5G) products, partially backed by Tata Group. It is comparable to CEWiT as an indigenous Indian telecom technology player benefiting from India's indigenization push, but is a commercial product company rather than a research society.
