    Right, that’s what I’m referencing. Why would you need two different WiFi cards and three different cellular modems?

      Ah this is want I need it for. It’s a potential CPE (many names but I hear mostly (customer provider equipment)). Instead of your ISP CPE = modem, I use these for edge connectivity for last mile edge solutions. I would be adding 5g cell, 4g LTE/5g w/satellite, WiFi /bluetooth, WiFi/IoT and broadcast(ATSC/DVB-NIP/5GBC)/IoT RF module cards and one SSD for a SQL database with a custom software for file delivery and video streaming. For consumers, great smart hub. Commercially, I make these for first responders.

        WiFi /bluetooth, WiFi/IoT

        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?

        broadcast(ATSC/DVB-NIP/5GBC)/IoT RF module cards

        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!

          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.

          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 $$$.
