The Government had approved the Scheme for establishing State Wide Area Networks (SWANs) across the country, in March, 2005 at a total outlay of Rs.3,334 crore to be expended by the Department under Grant-in-Aid of Rs. 2,005 crore, over a period of five years. Under this Scheme, technical and financial assistance are being provided to the States/UTs for establishing SWANs to connect all State/UT Headquarters up to the Block level via District/ sub-Divisional Headquarters, in a vertical hierarchical structure with a minimum bandwidth capacity of 2 Mbps per link. Each of the State / UT can enhance the bandwidth up to 34 Mbps between SHQ and DHQ and upto 8 Mbps between DHQ and BHQ depending upon the utilization.
SWAN is envisaged as the converged backbone network for data, voice and video communications throughout a State/UT with the following salient features:
- One PoP at each State / District / Block Headquarter
- Each PoP has Configurable Aggregation Equipment to enable vertical & horizontal connectivity Gateway to NICNET (National Backbone) for Inter-State connectivity.
- State/ NIC would receive discounted price for BSNL BW cost (MoU signed)
