Q. Is the product certified for use in Europe at 868 MHz?
A. Products are certified for use in Europe and North America.


Q. Tags may be fitted to assets that travel between Europe and North America
or vice versa. How can the different frequency bands be handled?
A.The same tag can be configured to operate at different frequencies, e.g. 868 MHz in Europe and 915 MHz in North America. Tags could be reconfigured to the new frequency before, during or after shipping.


Q. Why do we use the 900MHz ISM band?
A. This band is well suite to long ranges, and low power applications. It is also, unlicensed; making is more cost effective for the end-users.


Q. We have other radio frequency systems on site. Will that impact the RFind system?
A. Other radio frequency systems may interfere with the RFind system if they operating at the same frequency. A site survey would determine whether any such interference will impact the RFind system.

Q. Do you use frequency hopping (FHSS)
A. No, we use spectrum selection.


Q. Does the system use Received Signal Strength (RSS) or Time of Arrival (ToA)?
A. The RFind system is a Received Signal Strength (RSS) system


Q. Can we do power over Ethernet (POE)?
A. POE can be support using a third party module. Different modules are available depending on your existing network hardware.


Q. Can the system be installed in multi-storey facilities?
A. Extra care must be taken when installing the system on multiple storeys to avoid bleed between different levels. Bleed could be reduced by increasing the number of reference tags, reducing the power of reference and asset tags.


Q. How does a changing environment affect the system?
A. The RFind system is designed to cope with a changing environment. Even if a tag is partially shielded by metal (for example, if a forklift drives in front of it), so that it can no longer communicate with all the nearby reference tags, it can still be located from responses from other reference tags. In a highly dynamic environment, the density of reference tags and gateways can be increased to improve coverage.


Q. How often do you have to calibrate the system?
A. The RFind system does not need to be calibrated.


Q. What are the warranty terms?
A. A one year warranty is provided.
