Trigon Vision: The rise in wide heterogeneity of end-user applications and telecom services has increased the end-user’s data consumption. The telecom industry is witnessing an exponential growth in video traffic, cloud based services and rising number of telecom subscribers. To sustain the increasing flow of data towards an end user the data rate of the entire broadband infrastructure has to evolve. This evolution has to happen across various verticals: (1) The Access Network (2) The Metro Network and (3) The Backbone Network. Where each vertical will have its own set of attributes: 

(a) Physical Layer Evolution: Will be responsible for increasing a subscriber's data rate and number of subscribers on a telecom infrastructure.

(b) Network Architecture Evolution: Improve ease of deployment of service, reduce latency and efficient utilization of telecom infrastructure resources (Spectrum, Power ...etc).

(c) End-User Security: Provides an infrastructure that sustains the rapid growth of telecom services and end-user data exchange while providing unconditional security. 

Overall, the growth of a telecom infrastructure can be compared to the health of a human anatomy. Both the access network and backbone network need to be strong while the security infrastructure provides the necessary immunity from eavesdroppers. This forms the basis for the Trigon Vision i.e. to have a sustained and secured broadband infrastructure growth.

Indian Scenario: Presently, India has about 450 million Mobile Broadband (MBB) subscribers and the aim is to connect about 550 million more citizens on to the digital platform through the Govt. of India's, Digital India and National Optical Fiber Network (NOFN) initiative. In addition, the Government intends to bring 5G services by 2020 in various Metro and Tier1/Smart Cities while the existing 3G infrastructure should find its way to the other low tier cities. Also, the per capita income or paying capacity of Indian citizens have to be kept in mind which for rural areas can go to as low as Rs. 50000 per annum. Therefore the Access network has to be cost effective, the Metro and Backbone network should be designed to cater the high volumes of data cumulatively generated by expected 1 billion MBB and broadband subscribers. This growth has to be supported in a secured environment. The Trigon Vision will address each problem individually and aid in sustaining the telecom growth of the country. 

Mission: To provide solutions for high capacity broadband telecommunication infrastructure that can sustain the rise in data traffic under a secured and cost effective environment.

Research Groups: Their agenda and impact on the society

  1. Visual Light Communication (VLC) Group:  The agenda is to provide a highly cost effective last mile telecom connectivity for Indian citizens in rural areas. This will connect a large number of users on the digital platform thereby contributing to the vision of Digital India and provide solutions to NOFN end user connectivity problems in these areas. 
  2.  Broadband Information Transport (BIT) Group: This group will work to design the next generation inter-city backbone and metro network infrastructure based on Elastic Optical Networks (EON). Presently, the inter-city backbone network uses DWDM where optical links operate at 40 Gbps. The EON technology will enable speeds >100 Gbps among the links.
  3. Quantum Information Communication (QIC) Group: To design end-to-end encryption key exchange infrastructure that enables the key exchange over Quantum Key Distribution (QKD) network. This network infrastructure while utilizing quantum communication postulates will try to provide unconditional security as a service to the subscribers (Security as a Service).
