:2.5Ghz is a little too close to the ISM band (2.4Ghz) to me. Consumer devices don't always stay in spec and can bleed over to higher channels.
I wouldn't be surprised if something as simple as a microwave caused interference for someone using this equipment.
2.5 is still high as far as penetration is concerned. Maybe if they can implement high sensitivity radios (-90dBm) it would be worthwhile.
-90dBm is very doable, it's all a matter of how many bits/second you're pumping through at what modulation.
