A hospital’s ability to effectively deliver services requires
a communication system that under rigorous time con
straints can handle information about patients. A wireless
transmission solution which links the positive patient iden
tiﬁcation with electronic medical records (EMR) is pre
sented in this paper. Also, a prototype device based on
IEEE 802.15.4 and RFID technologies was developed. Dif
ferent RFID tags (patient, nurse, medical device) are re
trieved by the RFID reader implemented into prototype.
After successful identiﬁcation sentence, the radio transpon
der starts sending the EMR data through access point to
server, which will link them with patient ID information.
All data can be referred, on real-time, by allowed person
nel from any networked device in the hospital (PC, PDA,
mobile, etc.). Employed identiﬁcation procedures reduce
signiﬁcantly the risk of patient misidentiﬁcation. More
over, the implementation of 6LoWPAN protocol makes this
solution technology independent and allows an easy transi
tion to another wireless technology like WLAN or UWB.
In this work, test regarding transmission factors and com
parison with other wireless technologies were performed.
These tests demonstrated that the 802.15.4 technology used
in this prototype is not efﬁcient enough. However, this so
lution combined with another wireless transmission tech
nology can be utilized and can consequently improve hos
