What's the 2.4G RFID location?
In a common 2.4G RFID positioning application, a person card or item label normally contains a cell and sends an active identification signal, which is deployed at the site ' s base station and is received by the platform to determine the area or calculated location of the object.
These systems focus on the timing of location updates, area access, historical trajectory and unusual alarm.
What's the UHF RFID?
When the label enters the radio frequency area formed by the RFID Reader antenna, it acquires energy and returns to the code, on which basis the system completes the identification, inventory or business verification of the item.
The UFRFID is usually designed around reading points and operational events, such as warehouse entrances, inventory areas or smart cabinets. It can indicate that the labels are found under a read condition, but do not naturally provide continuous real-time trajectory.
2.4 G RFID positioning and the main difference between UHF RFID
| Comparative item | 2.4G RFID positioning | Common Unsourced UHF RFID |
|---|---|---|
| Working methods | Labels usually send signals on active cycles and base stations receive them on a continuous basis | RFID Reader initiates identification, labels respond in radio frequency range. |
| Label Type | Usually a battery-borne active locator card or label | Usually, it's a passive electronic label, and there are other forms. |
| Application target | Area position, trajectory, exit and abnormal alarm | Identification, inventory, access to and verification of the goods |
| Read Method | Multiple base stations and platforms continuously handle locational events | Handheld terminal or fixed reading and writing point by task |
| Maintenance focus | Label batteries, base lines, maps and location rules. | Label installation, antenna area, power and business interface |
The table describes the common project path, which does not mean that all 2.4G or UHF products are in exactly the same type of protocol, precision and label.
2.4 G RFID positioning and how should UHF RFID choose?
- Prioritize the assessment of positioning systems when current areas, tracks and cross-border incidents of persons or items require ongoing knowledge
- If low maintenance labels are required for bulk inventory, access to libraries or commodity verification, priority is given to the assessment of MHF RFID
- When locational awareness and inventory identification are required, both sets of technologies can be aligned along operational boundaries, rather than imposing one technology on the full range of functions.
The selection should be preceded by a clear number of objects, how the label is maintained, the required size of the position, the time of refreshing, reading of the area and the system interface, and the use of physical building and business process tests.

FAQs
2.4G RFID positioning labels need batteries?
Common active 2.4G positioning labels typically include batteries, but the specific product form and mode of work should be based on the equipment specifications.
Could UHF RFID be a real-time location for people?
The UHF can be found in the deployment point sensor label, but the normal passive UF system is not normally equivalent to continuous real-time positioning and is appropriate depending on the particle size and how it is updated.
2.4G positioning accuracy must be higher than UHF?
This cannot be compared. The two apply different objectives, and positioning accuracy also depends on base stations, algorithms, environment and deployment; the UF is more used for identification and operational area judgement.
Can the GPS and the UHF inventory systems be used together?
Yes. The positioning system is responsible for the location and trajectory of the area and the UHF system for the identification, inventory and operational verification of the item, which can be linked through a platform or interface.
