Satellite Communication can play a big role in India’s ambition to transform itself into a country empowered by digital technologies. In India, Satellite technology is especially suited for far flung and difficult terrain areas like North Eastern States, Leh, Ladakh, Andaman & Nicobar Islands, Lakshadweep, etc. It would be extremely useful in areas where laying optical fiber cables or installing mobile towers are difficult and next to impossible. With the recent development of High-Speed Satellite (HTS) technology in Ku & Ka band, the bandwidth available for communication need has increased many folds and cost of bandwidth has reduced tremendously.
With this background, merging of both Wi-Fi for access and Satellite technology for backhaul makes most sense to provide digital connectivity in our country. C-DOT C-Sat-Fi is designed as an autonomous infrastructure which can be deployed easily at rural areas. The complete solution comprises of C-DOT BBWT system, VSAT or SmartLNB terminal, Solar panel for powering through renewable solar energy and Charge control unit with inbuilt battery having the provision of dual power feed i.e. Grid power and Solar power designed and developed on the single pole architecture. The complete system can be easily installed on the rooftop of any type of building and on the ground level.

• India

• Remote and rural communities
• APPLICATION AREAS OF SATELLITE BASED BROADBAND - 1)Connectivity in Rural and difficult terrain 2) In-Flight Connectivity & Maritime Broadband 3)Backhaul for 4G/LTE and now 5G IoT application 4)On-Board Train Connectivity 5)Connectivity in Disaster conditions 6)M2M and IoT connectivity 7)Video distribution using setup box and multi cast to uni cast distribution

• Quality of service can be configured per user basis, thus ensuring configurable band width per user.
• Range of C-DOT Wi-Fi system will be approx. 500mtrs-800mtrs depending on terrain, vegetation & concrete obstacles.
• C-DOT system is rugged and designed especially suited for rural and remote terrain.
• Solar based C-DOT Solution is a dual power system and relies on Green Power Supply designed by C-DOT. Green Power Supply sources power from solar panel, stores in Battery and uses it to power Solar Wi-Fi and VAST/SmartLNB during power interruptions. Battery capacity can be dimension depending on backup requirements. The complete solution takes as less as 15 watts of peak load and can tolerate wide voltage fluctuations.

Wi-Fi is the most suited technology to provide connectivity in rural and unconnected areas. Digital Push in India • Digital India: ‘Digital India’ program envisions to “transform India into a digitally empowered society and knowledge economy”. The government intends to achieve this by focusing on three vision areas, namely: Digital Infrastructure as a Core Utility to Every Citizen; Governance and Services on Demand; and Digital Empowerment of Citizens. The Digital India program has the potential to provide an incremental 20-30% increase in India's GDP by 2025. • BharatNet: India has launched BharatNet National Optical Fiber Network project and has set a target to connect all 250 thousand Gram Panchayats (GPs) with optic fiber. More than 100 thousand GPs are already covered under this program. • NDCP 2018: National Digital Communications Policy (NDCP) – 2018 is the national policy document to prepare the country and its citizens for the future through digital infrastructure in the country. The policy document establishes a National Broadband Mission to secure universal broadband access for all Indian citizens with following targets: ◦ BharatNet – Providing 1 Gbps bandwidth to each Gram Panchayats upgradable to 10 Gbps ◦ GramNet – Connecting all key rural development institutions with 10 Mbps bandwidth upgradable to 100 Mbps ◦ NagarNet – Establishing 1 Million public Wi-Fi Hotspots in urban areas ◦ JanWiFi – Establishing 2 Million Wi-Fi Hotspots in rural areas The policy document also focusses on “Strengthening Satellite Communication Technologies in India” by ◦ Reviewing the regulatory regime for satellite communications ◦ Optimizing Satellite communication technologies ◦ Developing an ecosystem for satellite communication in India
