Wimax holds big potential when it comes to connecting the rural parts of the country.

After a number of years that involved intense interest and high expectations, Mobile WiMAX is being deployed within various operators networks and is already churning out profitability for them. And when it comes to a country like India, where most of the population resides in unconnected parts of the country, Wimax holds great potential to connect the unconnected and hence wimax driven products and solutions are becoming commercially available today and end to end wimax strategy is delivering big advantage for the operator community.

Global Network operators as well as their counterparts in India, are busy evaluating or planning for wimax deployments and this involves selecting vendors, identifying the appropriate network architecture and often deciding how to integrate mobile WiMAX within their legacy and existing network infrastructure.

As more and more operators consider the Wimax option, attention is gradually widening beyond its initial focus on the radio interface. It was the natural place to start, as it is the main building block of a WiMAX network and is responsible for most of the spectrum efficiency and cost savings that WiMAX promises.

As the operators start to plan end-to-end networks, however, network operators have increasingly been looking beyond the air interface, to the entire Access Service Network and the Connectivity Service Network. The ASN coordinates traffic across multiple Base Transceiver Stations and supports on the security front and Quality of Service.

The CSN manages core network operations through Internet Protocol (IP) servers, Authorization, Authentication and Accounting (AAA), Voice over Internet Protocol (VoIP) and Public Switched Telephone Network (PSTN) gateways, and it provides an interface to legacy core networks and other operators’ networks.

Driving one of the biggest advantages in favor of Wimax terchnology, the open IP architecture which is at the core of WiMAX marks a pivotal innovation among non-proprietary mobile technologies today. It is eventually decreasing the complexity and cost to network operators, while increasing the flexibility in developing new services and applications and the freedom in selecting the best suited vendors.

Hence, as a result, today’s operators are going in for end to end wimax adoption which is likely to deliver greater value to them on the long run and ensure their network reaches out to the unconnected masses of the country.
