SDR can act as a key enabling technology for a variety of other reconfigurable radio equipments. While SDR is not required to implement any of these radio types, SDR technologies can provide the above types of radio with the flexibility necessary for them to achieve their full potential, the benefits of which can help to reduce cost and increase system efficiencies.
It takes time for a new technology to evolve from the lab to the field. Since SDR is relatively new, it is not yet clear where it can be applied. Some of the most significant advantages and applications are summarized below.
• Interoperability. An SDR can seamlessly communicate with multiple incompatible radios or act as a bridge between them. Interoperability was a primary reason for the US military’s interest in, and funding of, SDR for the past 30 …show more content…

Following are some of the problems faced by the wireless communication industry due to implementation of wireless networking infrastructure equipment and terminals completely in hardware:
1. Commercial wireless network standards are continuously evolving from 2G to 2.5G/3G and then further onto 4G. Each generation of networks differ significantly in linklayer protocol standards causing problems to subscribers, wireless network operators and equipment vendors. Subscribers are forced to buy new handsets whenever a new generation of network standards is deployed. Wireless network operators face problems during migration of the network from one generation to next due to presence of large number of subscribers using legacy handsets that may be incompatible with newer generation network.
The network operators also need to incur high equipment costs when migrating from one generation to next. Equipment vendors face problems in rolling out newer generation equipment due to short time-to-market
