“…SDR gives the solution through inter-operability [27] by implementing Multi-data and multiple protocols communication through software and generic hardware without any constraint. Overview of the various design approach such as USRP N-series that includes GPPs, GPUs, DSPs, FPGAs are discussed and co-design approaches mentioned in [28] help to implement different communicationstandard through programming capability. TCXO stands for Temperature Controlled Oscillator, controls theTemp-erature of the device to drift slightly by 0.5 parts per million so that it stay on frequency.…”

When events are uncontrolled due to hurricanes, the communication will breakdown. During this strenuous situation there is a need for reliable communication system to provide alert and emergency services. There remains a particular attention towards portability, reconfigurability, and interoperability in a communication system to reduce response time during emergencies. The real-time implementation helps to come across alternatives to overcome practical difficulties and challenges. This motivates us to implement a Relay Node in real-time using SDR , hence an experiment is carried out in order to gain first hand experience between different types of architecture of SDR i.e.VUSDR, HackRF One, and USRP. The architecture of Low-cost VUSDR and comparison between different types of SDR has been presented in this paper. Future scope and applications are presented.

“…Radio hardware. Hardware based radio systems have very less capabilities limited just to receive particular signals only and physical interventions required to make changes in the system [3]. Using Software Defined Radio a reconfigurable system is implemented which can be used for wireless signal detection applications.…”

Low cost signal detection and monitoring system is designed in this paper. Wireless Transmission Monitoring is required by security agencies in order to check transmissions taking place in a particular area. In this paper Wireless Transmission Monitoring System is implemented using GNU Radio and RTL-SDR device. The implemented system is capable to monitor signals of GSM Transmission, Commercial FM Broadcast; the system is developed using Software Defined Radio based RTL-SDR hardware. Monitoring System can also be extended as a signal receiver by making certain additions in the designed model. In this paper Multiple RTL-SDR device based signal detection system is also designed. FM signals were successfully detected by the system in laboratory environment.

“…Software Defined Radio (SDR) is one of the most significant and latest technologies already and profusely commercially in use for modern wireless communication-related systems. SDR, the hardware platform of almost all CR, can tune different frequency ranges and implement various (de-)modulation schemes and various standards in the same device/hardware by using a reconfigurable hardware and software system [5]. In SDR, a broader range of capabilities depends on elements which are basically software configurable [6].…”

This paper is the design of a Radio Environment Map (REM) with a real-time tool to sense the radiofrequency spectrum and optimally places with Surrogate Modelling and Sequential Experimental Design tools a total of 72 SDR sensors in the selected area, using LoRa and/or NB-IoT technologies for networking. It permits the regulatory body to check the correct use of the assigned spectrum and constitutes a communication alternative in case of a catastrophic event, such as a hurricane or an earthquake, where radio and TV broadcasting play an important role in keeping people informed after such meteorological event. The radiobroadcast services use large antennas and high towers, making them vulnerable to such events. Regardless of the chosen technology, the IoT monitoring network will be more robust, since it uses small antennas and lower towers, and often a given area is covered by multiple base stations. The tool can be used to deploy new services in the nonserved area (e.g., 4G in the 700 MHz band at a lower cost or using TVWS techniques to provide communications and internet connection) and optimal interference management.
