UHF/ultra-high frequency characteristics

This article mainly introduces the characteristics of UHF/UHF, which ones are incompatible and which cannot be contacted. This article provides a brief explanation.

The characteristics of UHF/UHF are as follows:

1: Do not come into contact with any metals or liquids.
2: EPC and USERS can repeatedly read and write and lock the data.
3: Mainly used in logistics, warehousing, and long-distance scenarios.
4: Distance from the reader and writer. The medium distance is about 6 meters, and the long distance is 10 to 15 meters.
5: Handheld devices are convenient but expensive, with short read/write distances.
6: The readout usually indicates the EPC area.
