While filters can help, the problem that I see is that filters are: 1) expensive and 2) bulky. Last time I checked, a cavity filter for the 902-928 range was roughly $300-$400. I don't see it being practical to install one of these at every customer site! Cavity filters are fine for your

If you have an adjacent channel carrier which is running hundreds of watts of power then you may not have a choice of whether to use the bandpass filter or not. Your system may not operate in the upper part of the 900 MHz band. What happens is that the adjacent carrier will swamp your receiver

Cavity Filters create several additional problems 1) Assuming most filters are narrow individual channel widths... It takes away the benefit to move your Radio Freq Channel to stear around interference on the fly. 2) Assuming 1 Filter covers the full width of the Band... The filters add

Bleed over implies that the paging system is transmitting a signal that is too wide. This is typically NOT the case. Our rather inexpensive WISP AP receivers do not have adequate selectivity to reject strong nearby signals. In other words, it's our equipment problem not their equipment

I concur. When a 900 MHz access point (AP) is located near a high-power paging (or other high-power) transmitter then a bandpass filter is cheap insurance to avoid or minimize the AP receiver desensing (overload) that the high-power transmitter may cause. It's impossible to know in advance how
