C-DOT to Launch Broadband Products

C-DOT, the premier R&D institute of the Department of Telecommunications, Govt

C-DOT, the premier R&D institute of the Department of Telecommunications, Govt. of India, has developed indigenous technologies attuned to the sensitive needs of Indian landscape aim at the digital convergence of rural and urban India with a vast potential for building the citadels of “Digital India”. The following 4 products are to launched by Hon’ble Minister of Communication & IT, Shri Ravi Shankar Prasad on 6th July the Digital India week as observed during 1st- 7th July 2015.

1.      Long Distance Wi-Fi System

2.      Solar Powered Wi-Fi System

3.      100Gbps OFC Link

4.      C-DOT Next Generation Network in MTNL Network


1.      Long Distance Wi-Fi System:


C-DOT’s Long Distance WiFi Solution is an all-encompassing, versatile wireless platform that is capable of extending WiFi & IP connectivity to the remote and inhospitable terrains of India in a cost-effective and power-efficient manner. The product is capable of providing 100Mbps broadband speed to users of distant locations. C-DOT’s Long Distance WiFi differentiates itself with the following unique attributes as wireless connectivity:

·        Direct Optical Fibre at WAN interface, which enables high speed connectivity with consistent bandwidth.

·        Mesh technology, which makes connectivity possible even where direct Line of Sight (LoS)is not present. This shall prove effective in its deployment to NE India where connectivity and hilly terrain remains a challenge.

·        Support to link redundancy in case of failure of one radio/link.

·        This technology is backed by robust operations, management  & maintenance software 

Provisioned with a solar powered green energy source, this solution can utilize enabling the seamless WiFi access over long distances in an efficacious manner.

2.      Solar Powered Wi-Fi System :

Solar Wifi operates in license exempt bands of 2.4 & 5.8GHz. The solution is specifically designed for outdoor environments, inaccessible terrains, where there is no guarantee for continuous power. The system is designed to work in variable input volatages and in harsh conditions. It  can  also  be  used  for  Backhaul  link  for  Wi-Fi  hot  spots,  cellular  base stations and base station controllers, ATMs, Database servers etc. Also the solution is well suited to extend last mile  wireless connectivity beyond Panchayat which are being connected to C-DOT developed Gigabit Passive Optical Network (GPON) technology forming the backbone of  Bharatnet -The National Optical Fiber Network (NOFN),

3.      100Gbps OFC Link :

Keeping in view the ever increasing demand for superior bandwidth, high speed and power efficiency in the fiercely competitive market scenario, C-DOT’s Suteevra is poised to play a significant role. In this fast moving digital world where it is hard to find PC port of less than 1GbE speed, Suteevra carries valuable significance in creating enabling infrastructure for providing high-speed user experience anytime, anywhere. The solution is capable of serving multiple applications and protocols ranging from the Data, Storage, TDM, ATM and Video networks. Suteevra is a versatile mini 100G OTN (Optical Transport Network) platform based on the latest standards offering the ease of being deployed in both Greenfield networks and existing OTN(Optical Transport Network) environments. Capable of supporting a distance of upto 50 Km without an amplifier, its uniquely designed system and management interfaces with clearly defined performance monitoring features make it ideally suited to the current market trends.

4.       C-DOT Next Generation Network (NGN) in MTNL Network


C-DOT’s  cost-effective NGN solution addresses the need of the changing  telecom scenario and enables TELCOs to make a smooth transition from legacy TDM ( Time Division Multiplexing) technology to  advance VoIP  Telecom technology. The technology has various components of hardware and software and they are all indigenously designed by C-DOT . In fact , a successful trial of the developed live network has been done for 1000 landline connections of legacy PSTN technologies to C-DOT’s IMS-compliant NGN technology. With this successful trial,  MTNL can  think of launching  various services ( voice, video and data) through various access based on IP. Also, it now possible to migrate its existing 3.5 million landline subscribers of MTNL  to IP based network.

These uniquely architected indigenous solutions can play a catalytic role in fulfilling the objective of holistic digital empowerment resulting in the creation of a knowledge economy as envisaged under the flagship mission, “Digital India” – A prorgamme to transform into digitally empowered society and knowledge economy.  Hon’ble MoC&IT  will launch C-DOT products designed and developed to take Broadband to every nook and corner of India. These products are essential infrastructure for broadband connectivity and enabler to facilitate delivery of services.
