Outdoor Channel Modeling at D-Band Frequencies for Future Fixed Wireless Access Applications

Outdoor Ultra Wideband Propagation Channel Modeling at Vhf/uhf Band

Due to the low power spectral properties of ultra wideband (UWB) signals, the technology is suitable to be used, e.g., in covert military applications. The open literature lacks of UWB radio channel models that are generated for outdoor use. This paper describes the radio channel measurement campaign carried out to increase the knowledge of the UWB propagation mechanisms in typical Finnish fore...

Channel Allocation for Broadband Fixed Wireless Access

Existing channel allocation methods are usually implemented for voice oriented services where the aim is to reduce the call blocking and call dropping rate. In this paper, we will investigate channel allocation schemes appropriate for data oriented services in a Broadband Fixed Wireless Access network where the aim is to reduce interference and improve overall packet throughput. A Fixed Channel...

Outdoor to Indoor Penetration Loss at 28 GHz for Fixed Wireless Access

This paper present the results from a 28 GHz channel sounding campaign performed to investigate the effects of outdoor to indoor penetration on the wireless propagation channel characteristics for an urban microcell in a fixed wireless access scenario. The measurements are performed with a realtime channel sounder, which can measure path loss up to 169 dB, and equipped with phased array antenna...

Indoor channel modeling at 60 GHz for wireless LAN applications

This paper reports narrowband and wideband results derived by propagation modeling at 60 GHz for indoor WLAN applications. A multi-ray model is proposed and verified through a simulation process. The propagation in the site-specific environment can be described using 4-5 rays without reducing the accuracy of the results. RMS delay spread varies with distance from 0.57 ns up to 2.32 ns. Coherenc...
