Technology Development
  1. Broadband Wireless Communications for Public Safety We are developing rapidly deployable base station sub system capable of being mounted in a command & control vehicle leveraging LTE/4G+ technology in sub 1 GHz spectrum with public safety and Client unit or radio handset with support for video.

  2. Test-Bed for Affordable Broadband in India using Backhaul in TV White Space
    While India has witnessed a spectacular growth in cellular wireless communication, broadband penetration is still considerably limited. Cost effective last mile broadband connectivity can be provided by cellular 3G/4G or WiFi network. However, cost effective backhaul connectivity to base station has been a major stumbling block for affordable broadband. In this regard, we envisage a solution for addressing the problem of backhaul for rural broadband using TV white space based middle mile. The propagation characteristics of the VHF/UHF signals make them ideal for use in rural areas where wired infrastructure is not cost efficient to deploy. We have setup test-beds in semi-urban/rural regions and determined technical parameters required for TV white space based operation of broadband services.

  3. Tata Teleservices IIT Bombay Telecom Center of Excellence and Technology Commercialization I played a leadership role in establishing Telecom Centers of Excellence (TCOE) in public-private partnership in five IITs, IISc and IIM. I also served on the Executive Council of TCOE India, a registered society during 2012-14. The center at IIT Bombay is being funded by Tata Teleservices and Department of Telecom and I am the Center Coordinator. As part of this center I directed many technology development projects-
    • Network OPEX Optimization
    • This patented technology is now being commercialized by Panchsheel Research Pvt Ltd.
    • Mobile Social Networking Platform (MSNP)
    • We have developed an innovative platform for facilitating and analyzing social contexts for providing targeted recommendations which has been granted a US patent. Some applications such as SmartPicks (handset bundle-offer), User Driven Health Care (UDHC) and Targeted caller tune recommendation have been field tested and deployed on Tata Teleservices Network.

      MSNP was launched in the curtain raiser ceremony of India Telecom 2011, New Delhi on 29th August, 2011. Here are few news items:

    • Low Cost Cellular Backhaul for Rural Access (CeBRA)
    • Our group has developed a novel low cost solution for cellular backhaul based on a modified optimized version of long distance unlicensed band radio. About 300 such links have been deployed in Tata Teleservices Network.

  4. Emergency Communication System for Force 1 Anti-Terrorist Commando Our group developed a state of the art emergency communication system for Force 1, an elite force formed to tackle terrorists in Maharashtra. This technology enables commandos' movements inside a building to be monitored in a remote control and command center through live video streaming over wireless. This development has been covered in press news item- 07/mumbai/30257234_1_research-centre-anti-terror-security-forces

  5. Open Source Software Development (Multiprotocol Label Switching (MPLS) Router) In my early years of research, I led a major project in open source software development in the area of Linux based Layer 3 router based on MPLS. The carefully planned effort of the team led to the development of Linux based MPLS router and the source code was made available worldwide in open source. It can be obtained from here. I also led the effort of developing Linux based MPLS emulator for research and development purposes.

  6. Past Technology Development Projects In the past I have worked on the following projects:
    • Metro Ethernet based Access Networks
    • In the years 2002-07, I was involved in the development of technology for telecom and broadband Internet access with specific focus on Indian service providers. Our team architected an innovative architecture that leverages the potential of Ethernet for providing Quality of Service (QoS) based triple play services. We also developed a novel method of transporting voice over packet switched networks like Ethernet and developed unique algorithms for enhancing the performance of packet voice communication.
      A white paper written on Eisodus technology is `A EisoAccess Solution- A Broadband (R) Evolution'. I have authored a more complete tutorial article on challenges for broadband access in emerging economines like India- `Challenges for Broadband Deployment in India and Role of Metro Ethernet'. The related presentation can be found here.
      Based on these ideas and with a vision to develop technology for Indian telecom markets indigenously, I founded a company called Eisodus Networks Private Limited. The company has been featured in Light Reading.
    • PARAM 9000 Super Computer Design
    • While as a Member of the Technical Staff and Team Coordinator in High Performance Computing and Communications (HPGC) group of C-DAC, Pune, I was responsible for the design of Interconnection Networks for the PARAM 9000 super computer.
