Software Defined Multimode Radio

Most of the people are familiar with number of mobile radio communication system like Garage door openers, cordless telephones, and handheld walkie- talkies are examples of mobile radio communication system. There is lots of variation in cost, complexity, types and performance of this system. The term ¿mobile¿ has been used to classify radio terminal that could be moved during operation. There is link between radio communication and Wireless networks which have been evolved from 1G to 4G networks which allow smart devices to become important tools in daily life. It is faster, it has better quality, and importantly it is more secure. As we know users can truly use network services anytime, anywhere, however with increasing demand, the use of bandwidth and frequency spectrum resources is beyond expectations. Current implementations of Internet systems are very hard to be upgraded. Hence, the ossification of existing standards restricts the development of more advanced communication systems [1]. Therefore new research initiatives, such as software-defined radios, and software-defined networks, Multimode Radio, and Multiband Radio allow more flexibility for networks.
