Software Defined Network (SDN)

Software Defined Network is a network architecture in which the network functions or control is moved networking devices to software. This migration of control from individual network devices into accessible computing devices enables the underlying infrastructure to be abstracted for applications and network services, which can treat the network as a virtual or logical entity.

Wireless systems

Assume it takes Rs.40,000/- to lay and provide land line connectivity to a house. Even if the subscriber pays a rent/subscription of Rs.400/- it will take 100 months to recover the cost alone. Other maintenance and operational costs are not included yet.

Landline Calls

India is having the largest growing telecom market with half of its population served by GSM/CDMA technology.

But still people have land line telephones. Either for home/office purposes. And above all, state run BSNL/MTNL and private firm Airtel provide broadband services over land line through DSL technology.
