Unsure. Our humanitarian driven use-cases are somewhat price sensitive.<br>
If the cheapest compliant device was around US$100 instead of US$20 -<br>
$30, then we would probably be forced to look at making our own devices<br>
(although we don't have the money for doing this at the moment).<br>

What is if a 2-times more expensive device has twice the range?<br>
<br>
I'm asking because looking back many years, I always had the feeling that none of the cheap TP-Link devices had a range comparable to the good old WRT54G. Without illegal transmission power tuning of course :)<br>
