Does that really require two cards? I just use VLANs to cordon off my IoT stuff, but even if I wanted them on a separate SSID can't routers do multiple SSIDs with one transceiver?
Would that be M.2 or mini-PCIe?
Also, is an RTL-SDR in the same category of device? 'Cause I can see how having one of those connected internally, as opposed to as a USB dongle hanging off the side, would be nice. Ditto if internal ZigBee/Thread modules are a thing, now that I think about it.
...okay, I get the appeal now. Thanks!
It all depends right? For first responders, they have strict guidelines for near and far use cases, redundancy, different frequencies for interference control..etc. there’s nice m-PCIe to m.2 adapters but m.2 is becoming more of a standard. Also if you go Qualcomm based chips which make it easier with Qualcomm Linux software solutions…. It’s all m.2 and latest and greatest with no worries except $$$.
If you have many IoT devices on your wifi it can have a negative impact. If you have too many wifi networks in range it can also cause issue. There's a sweet spot in there though. And generally a good idea to have them on their own AP if not VLAN as well.
