Implementation of Multiband Communication Using SDR for Remote Application

Abstract

To develop Next Generation Wireless Communication a generic hardware design is required so that it can be driven by software to allow for future upgrades. Thus Reconfigurable Radio implements multi-band, multi-mode operation and interoperability with low-cost. For reducing response time between incompatible radios during emergencies interoperability is essential for a secure heterogeneous communication. Some of the Challenges identified for implementing reliable and reconfigurable wireless communication systems are: specific training required for using the equipment, end-to-end connectivity between devices, extending link capacity during the high peak utilization. Each device and architecture will differ based on the type of communication system. Interconnecting emerging fields enhances the performance , implementation helps to come across alternatives to overcome practical difficulties and challenges of connecting different fields to Cognitive Radio(CR). Earlier research gave prominence to theoretical and simulation-based work. This motivates us to verify interoperability in real time using SDR. This paper describes the implementation of a Multiband, multimode operation for establishing communication between different types of architecture i.e. VUSDR (HAM), Hack RF One, LoRa, RF module, GSM module and USRP N210 to prove reliability and end-to-end communication.

“…Radio Environment GNU Radio is open source software that is a set of tools for developing software-defined radio (SDR) systems. It provides users with blocks (nodes) for signal processing that can be used to create various radio systems, ranging from conventional radio receivers to new generation communication systems ("Tutorials," GNU Radio, 21-Jul-2022;Mi-yashiro, H., Medrano, M., Huarcaya, J., & Lezama, J., 2017;Gummineni, M., & Polipalli, T.
