Smartphones are affordable devices nowadays, capable of embedding a large variety of sensors such as magnetometers or orientation sensors, but also the hardware needed to connect them to most wireless communication technologies such as Wi-Fi, …
In this work, we show how to set up a cellular LTE network for wireless experimentation and measurement, relying on commodity hardware and open-source software. We first deploy a complete LTE network on a single laptop and an SDR hardware. Then, we …
This work presents the design of a NB-IoT integrated antenna for LTE band 20 on a compact 50x30 mm terminal. The study will start from the Q factor limitation analysis and finish with a simulated prototype considering the different techniques to …
This paper presents the study of a method used for decoupling radiating elements in the case of a multiband structure dedicated to small LTE Smart Cells. This method consists in using a power splitter and a phase shifter connected between the feeds …
This paper presents a multiband MIMO antenna system with four accesses, with very good performance despite the complex environment that surrounds it. This environment consists of a thick plastic radome protecting the antenna and an aluminum metallic …
This paper presents a low-cost measurement method for MIMO antenna performance assessment based on the open-source OpenAirInterface initiative. A first measurement is presented with a prototype with 8 antennas at 2.6 GHz integrated into a …
This letter presents a reconfigurable antenna for mobile terminals with extended band coverage obtained by using a digitally tunable capacitor (DTC). The antenna structure is matched permanently over high frequency bands including DCS/PCS, UMTS, LTE …
In this letter, a dual-band fractal monopole antenna suitable for Long Term Evolution (LTE) standard is proposed. The antenna geometry is based on a perturbed planar Sierpinski fractal shape, whose geometrical descriptors are determined by means of a …
