      A huge difference is penetration. Different frequency ranges penetrate walls and other materials differently. So 2.4GHz tends to go through houses way better and farther than 5GHz does. 5GHz is able to communicate on a tighter band because the wavelength is shorter, so you can fit more channels into the same relative space.

        If you have a bunch of internet if things devices, thermostat, lighting etc. Do you need a server?

          No, there is no relationship.

            @mary that would be kind of like "if I have a lot of motorcycles, do I need a tractor trailer".

              @scottalanmiller it was kind of confusing when he said you access a centralized server to gain access, I was wondering why lol.

                Presumably he means the central server to which the IoT devices connect. Nearly any IoT talks to a server somewhere, most are useless on their own. So they have a server but you don't have a server in most cases.

                  Think about a thermostat that you can connect to online. The thermostat IoT device is in your home. The IoT vendor has a server. You work with the thermostat through the hosted server somewhere. If that server was compromised, bad guys could run up your AC bill.

                    To bad most cameras don't work that way - instead they use uPNP to open ports and just spew your video feeds to the world.

                      "Most" of anything is crap. No good camera does that. What a bizarre system.

                        Agreed - but it's very likely type of equipment they'll run into out in the wild.

                          I've never seen that with a client in the wild. I'm sure it happens, but it's not something we really run into. Common with home users, for sure. As business class routers don't allow that, it limits it in the field a lot.

                          And it's not like we don't see cameras, worked with a security company just today!

                          Also, lots of customers on cheaper or less "business" equipment often have double NAT which while awful, stops UPnP.
