Answer:The PTM-10 is analogue transmittion. (3)What is the better frequency to Brazil? Answer: we suggest users from Brazil use the 500MHz frequency band. Part of the 900MHz frequency band might encounter frequency in Brazil WHAT OUR USER SAID: View more Buyer...
The chart below shows the read range differences across the common RFID frequency ranges. RFID Frequency BandRead Distance Low Frequency (LF/NFC)< 10 cm High Frequency (HF)< 1 m Ultra-High Frequency (UHF)1 – 100 m Reader Strength
The reader was suitable for uhra-high frequency band. Compared with other kind of reader which adopted traditional random anti_collision algorithm, this reader can smoothly read tags under more than one tags'cirumstance, and anti_collision performance has a certain improvement. 【期刊名称】《电子...
4、coefficient is less than -10dB between 640 and 980 MHz, which cover the whole UHF frequency band. The gain at 20920MHz of this antenna is 1.55dB. Measurement result is agreeable with the simulation result. Keywords: Electromagnetic field and electromagnetic wave; UHF; RFID; Tag Antenna; ...
