If their signal occupies the whole band it is probably FHSS in nature. So changing to a 5 or 10 Mhz. channel will not be possible. Also, it may not be possible to turn down the power. So it may not be that simple. A certified letter from an attorney is probably more in order.

no, 900 mhz rfid would be 20mhz bands. They MUST be exceeding EIRP, tho, because I've never seen problems with rfid at close ranges like that, and not having good reads with normal, or even less than normal power. Problem is, rfid is 100% tx/rx 100% of the time. How far away is this from you ?
