The radio has increased the reception frequency from 45 MHz to 6 GHz operating between 900 MHz and 6 GHz. At this frequency, the radio was able to cover a wide range of the available mobile communication areas. Figure 1 shows the frequency allocation of the present mobile communication, the global positioning, and broadcasting systems. The incorporation of Bluetooth application played a significant role in increasing the frequency and the bandwidth. Figure 1: Frequency allocation of mobile communication, global positioning, and broadcasting systems On the other hand, the radio receiver had to be designed in a manner that it would be compatible with the future receivers. The receiver transferred low-power radio frequency signal to a complex baseband signal. The design considered all performance parameters that included noise figure (NF), dynamic range, third order interception point (TOI), image rejection, filtering, and signal to noise ratio. In order to ensure quality configuration of the radio, the input power level, bandwidth, frequency, and modulation were variable. The software was designed to transfer signals to a dynamic range and have a flexible fixed bandwidth. Design engineers faced many challenges despite the popularity and demand for software defines radio. Simulation and design techniques were employed in delivering quality product to optimize its operations (Garcia et al 1156-1161). The new developed software provides users with an easier operating environment since a task radio behavior is set and the hardware is left to implement radio frequencies. In addition, the design team produced a small and simple receiver manufactured as an integrated circuit (IC). The...
This paper approves that the analog to digital converters were also used in the design. The traditional radio receivers used external antenna at radio frequencies. The design engineers could not perform direct digitalization of microwave frequencies which posed a big challenge. The introduction of analog to digital converters made information more accessible and easier to decode. The mobile communication gadgets were fitted with the application from the manufacturers making it easier to convert frequencies. On the other hand, the traditional radio used antennas for single frequency band. Because of the increasing communication jam, engineers designed an application that could accommodate multiple calls at ago.
This report makes a conclusion that the development of software define radio technology has changed the way in which people communicate using mobile phones. Many researchers have been conducted on the suitability of the application and how it could fit in the future world of communication. Wireless and mobility concept has allowed societies to share more information in an efficient and timely manner therefore, bringing life changing services to communities. The radio services have contributed a lot in educating, empowering, and delighting people on how to handle future technological changes. The revolution has changed even the ways in which people carry out their businesses in the present society. Each day experts come up with new methods of wireless communication that enable people to connect, share, and make innovations using wireless and mobility concept. The following application was found out to be very efficient, power saving, and capable of rejecting high levels of frequency interference.
