Universal Software Radio Peripheral (USRP) and GNU Radio are well known Software Defined Radio (SDR) tools. The USRPs designed by Ettus Research are used without a deep knowledge of their performances. In this paper, we report our output power measurements using a USRP B210 driven by a GNU Radio program. Our results show that the obtained output power decreases as the selected central frequency increases...
In this paper we report Radio Frequency (RF) measurements performed on a GNU Radio/Universal Software Radio Peripheral (USRP) testbed. The USRP hardware is connected to SBX daughter board, both designed by Ettus Research. We can confirm the bandwidth stated by the designer, nonetheless the output power was found to be constantly decreasing with increasing the output frequency. USRP Hardware Driver...
In this paper, we propose an empirical model based on Radio Frequency (RF) measurements. The output power is measured sweeping a frequency band from 350 MHz to 4400 MHz of four SBX daughter boards [4]. These daughter boards are connected to a Universal Software Radio Peripheral (USRP) N210. For each carrier frequency, a narrow-band sinusoidal signal is generated by a GNU Radio Software Defined Radio...
In this paper, we report a series of RF (Radio Frequency) measurements performed on a USRP and a GNU Radio Software Defined Radio (SDR). The RFX 900 and RFX 2400 Daughter Boards are connected to an USRP N210 platform and driven by the GNU Radio open source software. We focused on two main aspects: the output RF bandwidth and the power linearity versus the DAC value for each daughter board. The measured...
Driven by the demographic variation in population and degradation of health care quality, we have witnessed in the recent years the explosion of healthcare applications market in order to provide high quality care. Wireless Sensor Networks (WSN) seem to be an attractive technology to deploy this type of applications thanks to their advantages of simplicity of deployment, safe of use and reduced installation...
