                                     State Wide Area Network (SWAN)

The Government has 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. Steps have been initiated to integrate all SWANs using the National Knowledge Network (NKN). Four States namely Gujrat, Tamilnadu, Karnataka and Andhra Pradesh have been integrated using NKN.

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)
