Mitigating people blockage by angular diversity at millimeter wave 5G bands

A measurement campaign was carried out in order to characterize the channel response when people are passing between transmitter and receiver in the 5G Frequency Range 2 and beyond (40 GHz and 60 GHz). We also studied the possibility of using angular diversity to compensate for the resultant fading. After analyzing the data, interesting results are obtained: fading values over 25 dB were measured at both bands; the level crossing rate is very similar in value and distribution at both frequencies, and the average duration of the resultant fadings is almost double at 60 GHz. It was also observed that the fading depth seems to be related to the stature of the person obstructing the radio link. A deeper fading is observing with taller individuals.A measurement campaign was carried out in order to characterize the channel response when people are passing between transmitter and receiver in the 5G Frequency Range 2 and beyond (40 GHz and 60 GHz).

RFID from Farm to Fork: Traceability along the complete food chain

The project "RFID from Farm to Fork" looks for the extension of RFID technologies along the complete food chain: from the farms where cows, fishes, sheep, grapes, etc. grow; to the final consumer at the supermarkets, including all intermediate stages: transports, factory processes, storage. The paper is intended to show the project objectives and concerns, as well as it highlights the main radio propagation problems detected within a RFID system installed in a food factory. The paper also shows a proposal of using RFID traceability in different study cases

RFID and WSNs for Traceability of Agricultural Goods from Farm to Fork: Electromagnetic and Deployment Aspects on Wine Test-Cases

The need of traceability systems adequate for food is a matter of fact: provenance, means of processing, time of the actions, temperature during transportation, are only a few of the possible data a consumer wants to know to buy with confidence. Among the others, the wine sector is especially susceptible of applying such a system: this sector produces highly added value products and the consumers are sensible to pay more money for a better (and also better traced) product. The RFID Farm to Fork project was born with the aim of testing the ability of RFID technology to implement a complete traceability system that covers the processes from the farm to the fork. In this work, based on the joint use of RFID technology and WSN, a system for the wine traceability from vineyard to the consumer glass is described along with related electromagnetic and deployment issues. Two different wineries, selected as pilot sites, are then presented and the current deployment status reported. © 2011 University of Split
