Long Distance UHF Passive RFID Reader 902928mhz Frequency 1520M JUTAI
Rfid Reader Distance. Some tags are similar to labels that can be directly stuck on the windscreen of the cars. Electromagnetic energy from the reader powers a passive rfid tag.

Generally speaking, rfid tag maximum read distances are as follows: Web what is the maximum read distance of rfid? Every long range rfid system consists of a reader that is connected to or integrated with an antenna. 125 khz and 134.2 khz usually 10 cm (4 inches) it is possible to get read distances over 30cm (1 foot), but these cases need individual assessment. The more closely the rfid tag is ‘tuned’ to the reader frequency, the stronger is the signal. These are the kinds of tags used in toll collection systems. Has the shortest read distance, about 10 centimeters between the reader and the tag. The read distance ranges from 10 centimeters to 1 meter. This gives them a read distance from close contact to 25 meters. The hf rfid system tags, transceivers, and interfaces are designed to the iso 15693 open standard.
General equation to find distance to rfid tag is ploss = 20⋅log[(4 π ⋅ d)/λ] in case of uhf rfid, the equation to find the gap or distance to passive tag from the reader is pgap = 22.6(db)+ patt, where 22.6db is the power for near field(λ =c/f ≈ 35cm), where f is frequency operated, patt is the magnitude of power attenuator. The read distance ranges from 10 centimeters to 1 meter. Web what is the maximum read distance of rfid? These are the kinds of tags used in toll collection systems.

The hf rfid system tags, transceivers, and interfaces are designed to the iso 15693 open standard. The uhf rfid transceivers are designed to the global.
