    Using mobile networks for effective cold chain management 

    Van Eyk, Bernardus P.; Hoffman, Alwyn J. (SATNAC, 2014)
    Research has shown that substantial in transit losses in perishable cargo are sustained due to malpractices in cold chain logistics. Such losses are even more prevalent in developing countries where supply chain systems ...

    Applying RFID technology to improve efficiency in border-post cargo clearance process 

    Bhero, Ernest; Hoffman, Alwyn (IEEE, 2013)
    Stakeholders in cross-border logistics and trade corridors have always been concerned about ways of improving operational efficiency. Cargo owners and cargo forwarders have been particularly concerned with long delays in ...

    A combined GPS/RFID system for improved cross-border management of freight consignments 

    Hoffman, Alwyn J.; Lusanga, Kabanda; Bhero, Ernest (IEEE, 2013)
    Inefficiency of road freight transport is one of the primary factors that hamper the economy of sub-Saharan Africa. Long delays experienced at border posts are the single biggest contributor towards the slow average movement ...

    SmartRoad: a new approach to law enforcement in dense traffic environments 

    Hoffman, Alwyn Jakobus; Pretorius, Albertus J. (IEEE, 2015)
    Road transport law enforcement is facing new challenges against the background of increasingly congested traffic conditions. An ideal law enforcement system must enable authorities to detect, identify and act against illegal ...

    Geometry based analysis of an alternative RFID interrogator placement for electronic vehicle identification 

    Hoffman, Alwyn Jakobus; Pretorius, Albertus; Wang, Yifan (IEEE, 2015)
    This paper proposes a solution for reliable in-traffic electronic vehicle detection based on UHF passive RFID (ISO/IEC 18000-63 - UHF Type C). The classic overhead placement of an interrogator reading a windscreen or plate ...

    Interference analysis of multiple in-road readers 

    Zhang, Lu; Pretorius, Albertus J.; Bialkowski, Konstanty S.; Abbosh, Amin M. (IEEE, 2018)
    In-road microwave readers and vehicle license plate tags provide superior advantages for traffic monitoring and vehicle identification. However, a single reader cannot accomplish the task of covering multi-lane roads. ...

    Kalman Filter based RFID tag velocity estimation in the presence of frequency hopping 

    Bester, Nico-Paul; Hoffman, Alwyn (IEEE, 2019)
    This paper compares different techniques for estimating the velocity of UHF RFID tags within practical applications. We use COTS RFID equipment complying with ISO18000-6C standards, including the use of frequency hopping, ...
