6.4.6 RFzones(Lfantennas)configuration
Each Gate Locator includes 4 ports of LF (Low‐Frequency, 125 KHz) antennas, used for exciting tags
(causing them to transmit). The tag will report to the base‐station the identity of the antenna that

Antenna name – For continence, the administrator can change the default names
“port 1” – “ port 4” to names that better represent the location in which the
antennaisinstalled,e.g.“meetingroom”,“Floor1elevators”etc.
Tag UHF Power – When a base station is excited through a specific channel, the
