> I understand there are use cases for low bandwidth, high range.
replyUse cases like IoT? The very thing this is for?
Is what you described a truth for all IoT devices? If I have los of my AP, why do I need 2.4Ghz? Even so, what SNR do you truly need for this low bandwidth application? Where is the engineering here?
replyI have a unique position of having a data set over 8000 APs with 40k unique devices. If you design properly, there is no need for 2.4 ever. 2.4Ghz congestion (with nearly no actual 802.11 traffic) is very high. To the point where the IoT folks are struggling.
2.4 GHz has the advantage of it passing through obstacles easier. The higher the frequency the more easily it gets blocked.
replyYes. And 2.4 lives and dies by that sword. What downsides might there be in areas where dozens of APs hear each other and 100s of clients hear each other?
replyMy 2.4ghz is basically all IOT these days. Things that matter are on 5 or 6 ghz. Busy moving the entire thing to be entirely firewalled off given how clean the separation is
reply>My 2.4ghz is basically all IOT these days.
replyYup. And it's exactly why some of my IoT admins are struggling. There is only so much spectrum to go around.
Don't think you're ever going to reclaim that spectrum successfully. There must be billions of devices on it. Pretty much any other ghz number is a better bet
replyIt's an IoT device, not a laptop. It does not really need 5ghz to fulfill its purpose as an embedded CPU, and adding 5ghz likely would require making some room for it by removing other functionality.
replyYes and in some uses cases it works against you. 2.4 is incredibly crowded without adding 802.11 to the mix. My IoT admins would have less complaints if they could take advantage of my small cell 5Ghz spectrum. This isn't 2005 with widely deployed asymmetrical wireless networks.
replyCan't you just underpower the antenna on a 2.4 radio if you need networks that don't bleed into each other as badly? Unless it's an issue because of the tiny antennas that usually come on microcontrollers.
