Long Distance UHF Passive RFID Reader 902928mhz Frequency 1520M JUTAI
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. Every long range rfid system consists of a reader that is connected to or integrated with an antenna. Generally speaking, rfid tag maximum read distances are as follows: 13.56 mhz usually under 1 meter (3 feet) 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. Tags that don’t have a power source. Web what is the maximum read distance of rfid? Web the working distance between a reader and a passive tag is greatest when they are in tune. Has the shortest read distance, about 10 centimeters between the reader and the tag.
The more closely the rfid tag is ‘tuned’ to the reader frequency, the stronger is the signal. Web low frequency rfid: These are the kinds of tags used in toll collection systems. The more closely the rfid tag is ‘tuned’ to the reader frequency, the stronger is the signal. Generally speaking, rfid tag maximum read distances are as follows: Tags that don’t have a power source. Electromagnetic energy from the reader powers a passive rfid tag. The uhf rfid transceivers are designed to the global. Low frequency covers ranges from 30 to 300 khz. Operates in a frequency range from 3 to 30 mhz. The hf rfid system tags, transceivers, and interfaces are designed to the iso 15693 open standard.
