India’s C-DOT Ready to Launch Broadband Products


One of the premier electronic research and development institute under the Department of Telecommunications in India, C-DOT has developed indigenous technologies needed for the digital convergence of rural and urban India, including long-distance Wi-Fi systems, solar-powered Wi-Fi systems, 100 Gbps optical fiber cable link, and C-DOT next-generation network in MTNL network.

The four products, to be launched by the minister of communication and IT Ravi Shankar Prasad on 6 July during the Digital India week (1-7 July 2015) have vast potential for building the citadels of `Digital India’, says an official release.

C-DOT’s long-distance Wi-Fi solution is an all-encompassing, versatile wireless platform that is capable of extending Wi-Fi and 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. It has the unique attributes of;
– Direct optical fiber at WAN interface, which enables high speed connectivity with consistent bandwidth
– Mesh technology, which makes connectivity possible even where the direct line of sight (LoS) is not present. This could 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, and maintenance software

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

Solar-powered Wi-Fi operates in license-exempt bands of 2.4 and 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 voltages and in harsh conditions. It can also be used for backhaul links 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 is being connected to C-DOT developed Gigabit Passive Optical Network (GPON) technology forming the backbone of Bharatnet -the National Optical Fiber Network (NOFN),

C-DOT’s Suteevra, the 100Gbps OFC link, takes into account the ever increasing demand for superior bandwidth, high speed, and power efficiency in the fiercely competitive market scenario and is poised to play a significant role. In this fast moving digital world where it is hard to find a 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 up to 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.

C-DOT’s cost-effective Next Generation Network (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 1,000 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 is now possible to migrate its existing 3.5 million landline subscribers of MTNL to an IP-based network.

These uniquely designed 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’.
