“…This is a consequence of nonperfect absorber panels since a ray reaches the RX after having been reflected between the RX and TX modules as described in [17]. Compared to other ultrawideband channel characterizations at 60 GHz in extreme multipath environments like a car with amplitude variations of more than 30 dB peak-to-peak (pp) [23], the measured variation still is almost negligible.…”

Ultrabroadband Terahertz communication systems are expected to help satisfy the ever-growing need for unoccupied bandwidth. Here, we present ultra broadband channel measurements at 300 GHz for two distinct indoor scenarios, a point-to-point link of devices on a desktop and the connection of a laptop to an access point in the middle of an office room. In the first setup, measurements are taken with regard to distance, different antenna types and device displacements. Additionally, an interference constellation according to the two-ray model is examined. In the second setup, the focus is on the detection and characterization of the LOS-and the NLOS-paths in an indoor environment, including a maximum of two reflections. Temporal channel characteristics are examined with regard to maximum achievable symbol rates. Furthermore, ray obstruction due to objects in the transmission path is investigated.

“…Therefore, the occurring channel gain (ratio of average received signal power to average transmit power, inverse of the path loss but including antenna gains) for practical positions is used as basic measure in this case without applying a distance-dependent model. In [13], the in-car channel has been analyzed for different application-oriented scenarios and propagation conditions. The channel gain has been found to be above −60 dB for LOS conditions [13].…”

The large bandwidth of the 60 GHz frequency band enables wireless short-range applications with data rates of several Gbit/s. The German project EASY-A has focused on early prototype implementations for selected applications, although no generally accepted 60 GHz standard has been available at the time. The implementations are based on application-oriented physical layer designs and link-budget investigations that account for the scenario-specific channel characteristics and for different integration technologies. This paper discusses the results of these investigations and details the hardware implementation of the digital baseband processing that relies on considerable parallelization. The link-budget results show that SiGe technology allows for 1 Gbit/s at a range of 3.5 m in non-line-of-sight environments, while up to 10 Gbit/s are feasible at more than 1 m in case of strong line of sight.

“…This model has to include the specific propagation characteristics of IVC environments. Several studies have started to investigate the IVC-UWB channel [5][6][7][8][9][10][11]. In [5], the authors present experimental results on the rms delay spread for two types of vehicles with different numbers of passengers and with different antenna's locations.…”

The increase in electronic entertainment equipments within vehicles has rendered the idea of replacing the wired links with intra-vehicle personal area networks. Ultra-wideband (UWB) seems an appropriate candidate technology to meet the required data rates for interconnecting such devices. In particular, the multiband OFDM (MB-OFDM) is able to provide very high transfer rates (up to 480 MBps) over relatively short distances and low transmit power. In order to evaluate the performances of UWB systems within vehicles, a reliable channel model is needed. In this paper, a nomadic system where a base station placed in the center of the dashboard wants to communicate with fixed devices placed at the rear seat is investigated. A single-input single-output (SISO) channel model for intra-vehicular communication (IVC) systems is proposed, based on reverberation chamber theory. The model is based on measurements conducted in real traffic conditions, with a varying number of passengers in the car. Temporal variations of the wireless channels are also characterized and parametrized. The proposed model is validated by comparing model-independent statistics with the measurements.
