5GHz RLAN Interference on Active Meteorological Radars
2005 IEEE 61st Vehicular Technology Conference, 2005This paper examines the effects of wireless access systems on meteorological radars operating in the band 5600-5650 MHz. It analyses data collected during field experiments involving IEEE 802.11a signals and the CWSR98 weather radar located in Franktown, Ontario, Canada. Results show levels of degradation on the gif, moment data, and ascope products of

Fairness of a decentralized RLAN based on asynchronous DS/CDMA
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002Performance figures are obtained for a decentralized radio local area network (RLAN) based on asynchronous direct-sequence code-division multiple-access (DS/CDMA). Packets are transmitted with equal powers and arrive at the spatially distributed receiver nodes with different power levels.

Effects of human shadowing, traffic and antenna movements on 62.4 GHz indoor RLAN's channels
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002This paper presents results of 62.4 GHz wideband propagation measurements of the indoor radio channel between fixed terminals. The impact of human shadowing, traffic and LAN's antenna movements on important channel characteristics such as coherence bandwidth, RMS delay spread and Rician K-factor are compared and evaluated.

Packet throughput figures are obtained for a decentralized radio local area network (RLAN) which is based on asynchronous direct-sequence code-division multiple-access (DS/CDMA). Packets arrive at the receiver nodes with different power levels. Techniques are developed to derive the probability of packet success for a system employing random periodic ...

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
Two multicarrier techniques are considered, coded orthogonal frequency division multiplexing (COFDM) and multicarrier CDMA (MC-CDMA). The paper presents the radio performance of these techniques at 60 GHz over Doppler and frequency-variant propagation channel models produced from wideband indoor measurements.

On Shared Use of Upper 6 GHz Band by IMT and RLANs
2024 IEEE Future Networks World Forum (FNWF)The paper evaluates the prospects for shared use of the frequency band 6425-7125 MHz by both the IMT mobile network operators and RLAN applications such as Wi-Fi, following recent ITU WRC-23 decisions. We aim to learn from similar past regulatory initiatives for shared use of spectrum, by proposing an alternative arrangement based on the concept of ...

RLAN impact on Sentinel-1 C-band SAR performance
2018Sentinel-1 C&D are expected to be launched in 2021, intended as a recurrent implementation of the previous -1A and -1B satellites. However, the C-band is under consideration for a potential allocation of the 5th Generation (5G) devices, including Wi-Fi and mobile devices that could interfere with the sensor operations and impact on Sentinel-1 SAR ...
