The Challenge
The Einstein analyst also pointed out the challenges for reading to take place as planned. “The hospital environment is naturally complex and presents several physical challenges that are inherent to the use of RFID, some uncontrolled variables directly impact the tag reading performance. These challenges are mainly related to the characteristics of the materials, electromagnetic fields, various means of transport and condition of the items”.
The initial challenges were about the choice of tag and reader models for a hospital environment, the definition and standardization of the installation of tags on items, the resistance of these materials and, mainly, the sensitivity of reading in different scenarios and contexts of use.
