If anyone here ever have this problem :
I've a couple of installations using Tiris S2000 reader with passive transponder.
Some sites have this problem :
Most of the day, the transponder can be charged and response within 1.5 meters, but for a few hours a day,this range fall to very low ,even 10mm from the antenna.
Then in the evening ,things go back to normal.
I suspect some machinery..eg fans etc is distturbing the low frequency of the Tiris (144Khz)
Synchronisation with nearby readers have been tried but little success to solve the problem above.
Does anyone have suggestions to counter-measure the disturbance? All equipment used are from TI. Anything to shift the freq. or boost..noise cancellation....help.
I'm brain-dead when dealing with antenna and RF stuff.
thks ..lak
