FAQ

Can your wireless sensors be used aboard aircraft on airfreight transportation?

Yes. The wireless sensors that we deploy (Ambient Systems SmartPoints and CartaSense wireless sensors) never transmit a radio-message when they are outside of their reader network. This is in contrast with traditional active RFID tags that always transmit messages at fixed intervals with an identification number. These tags have been designed to first listen for a reader when to want to transmit a message, such as a temperature-recording. When in range of a reader they will exchange a security key and transmit the message. When not in range in (for example aboard an aircraft) these tags will simply log the temperature-recording, and transmit its log at a later stage.

If you want to use our wireless sensors on your shipments aboard an aircraft, please consult with your air carrier. A number of air carriers have already approved the use of these sensors after careful evaluation. We are happy to support any inquiries.

Can the Ambient wireless mesh network interfere with existing WiFi (IEEE 802.11) networks?

No.The Ambient networks form an independent network that operate on an IEEE standard 802.15.4. communication protocol for ultra-low power radio. The radio frequency does not overlap with WiFi. To be approved as an  IEEE 802 standard, a coexistence document and plan ensures all 802 wireless standards can operate and coexist in the same space.

Can the Ambient wireless mesh networks impact biological products?

No. A recent study commissioned by the Parenteral Drug Association (PDA) shows that RFID technology is both safe and suitable for use in the presence of biologics. The study, “Effects of Radio Frequency Identification-related Radiation on In Vitro Biologics,” was conducted by researchers at The University of South Florida, Blood Center of Wisconsin, Abbott, Georgia Institute of Technology and the Madison RFID Lab at the University of Wisconsin was published in the July-August edition of the PDA Journal of Pharmaceutical Science and Technology. The report noted that RFID-based equipment could be used safely in close proximity to biologics, making the technology suitable for “track and trace” operations. The research showed that in vitro test results for more than 100 biopharmaceutical products from eight major drug companies demonstrated no non-thermal effect by radio frequency radiation. To obtain a copy of the PDA article, visit http://journal.pda.org/content/66/4.toc.

Are there security risks?

No.The Ambient wireless network operates on its own patented mesh network and is a standalone system, there are no security concerns relating to HIPAA regulations and standards. SmartPoints are the only wireless clients allowed on the network and they have limited communication capabilities.

The data collected from the Ambient’s wireless networks is encrypted and is securely stored in the SmartView databases. These are hosted in a hardened secure data center, in accordance with Good Distribution Practices and CFR 21 Part 11 regulations.
