How does the RFID locate people to determine where they are?
- Persons carrying identity-bound locator tags or card
- Field base station receives a standard signal from the label
- Platform processes data in conjunction with base site locations, signals and regional configuration
- Map or area list showing last valid position and time of person
Different technologies may use regional base station judgement, signal strength, multi-base station calculation or other methods. This paper is based on a sense of regional level, and the location results indicate that a person is located in an area or close to a point, and should not be interpreted as a uniform centimetre-level coordinates.
When the label is offline, the base station network is interrupted or the signal is blocked, the platform may display only the last position. The page should therefore display both the update time and the online status, avoiding misperception of the historical record as the current real-time location.
What's an RFID electronic fence?
The system can set an area as a restricted area, restricted stay, assigned a class to an operational area that is accessible or needs to focus attention.
The rules of the fence should consider positioning a new cycle and regional boundary fluctuations, with duration or multiple confirmations, if necessary, to reduce the number of repeated alerts caused by the movement of persons near the border.
How does RFID record the history of people?
The platform can keep a time-based view of the area where the person is located, the event of entry and departure, and the order of the area change, and then search for a time-frame of activity with permission. The area positioning project usually creates a regional sequence, not a continuous precise coordinate curve.
- Recording of location incident time and system reception time
- Preservation of the link between the area, base station and personal identity
- Mark label offline, data gaps or manual fixes
- Set Query Ranges, Save Duration and Export Permissions by Job
Location data relate to the privacy of persons and the management of boundaries, and projects should specify their use, means of communication, access rights and the periodicity of their preservation, avoiding the indefinite retention of technically capable data.
How does RFID achieve emergency call-ups?
- After an emergency event, the platform develops a range of personnel to be verified
- Current online statistical positioning system personnel and final effective area
- Display list by assembly area, hazard area and status to be confirmed
- The site supervisor verifies against the physical roll call, security gate records, and shift information
- Save evacuated, pending confirmation and manually modified results
Positioning data can narrow the scope of verification but is not an absolute safety guarantee. People may not carry tags, tags may be offline, and the last known position may be out of date. Emergency procedures should still combine on-site roll call, communications, security gates, and existing safety policies, and should be rehearsed regularly for abnormal situations.
What kind of scene does RFID locate?
- The plant and the park are in control.
- Field management and focus area alerts for storage sites
- Recording of entry and stay in laboratories, rooms and priority areas
- Area personnel support inventory for emergency response
- Regional-level search for mobile devices or critical items
If the business requires only identification, access to the warehouse or lot count of the items, the UFF RFID may be more appropriate; if continuous area perception, trajectory and fencing events are required, the source location programme should be evaluated.What's the difference between 2.4 G RFID and UHF RFID?。

FAQs
Can RFID position people in real time?
The latest effective position can be shown by system refreshing cycle, but real-time is affected by label dispatch cycles, base stations, networks and platform processing, and the page should show both the time of update and the status online.
Does the RFID electronic fence require physical fencing?
Not necessarily. An electronic fence mainly defines zones and rules in software, while physical isolation, security gates, or warning devices may still be installed on site according to safety requirements.
Can RFID check the history of people?
The location of the area usually shows the order of the area and time that the person is passing, rather than the precise coordinates that are continuous.
What's the RFID's accuracy in position?
The accuracy depends on positioning techniques, base station deployment, building structures, shielding, algorithms and the field environment.
