BT Infinity home hub with Open Reach modem attached

Hi Again, hope someone can give me some help with info about the above hub. According to the instructions given to me when the hub was installed, the hub has automatic dual band smart wireless with 2.4G and 5G which will connect to the best signal on either band. There is no switching choice available ( as there are on some bt models) so my question is..if I use a camera that is designed to operate 2.4G , will the hub be OK to use..will it know to operate on that frequency or is it dependant on my local area incoming signal, or is it the camera that generates a 2.4G signal when it is powered up? Just hoping someone on the forum can explain it to me..... Thanks once more.

Short version: Almost all wi-fi kit is backwards and forwards compatible. The main exception is 802.11a devices which aren't always supported. However, they only operated at 5Ghz, so your camera supports at least one other standard such as 802.11b, 802.11g or 802.11n and will work fine.

Thanks Endless waves... I think I understand now....I take it that if I buy a 2.4G camera it will operate at one of the latter three that you mention (11b, 11g or 11n) so my modem should be able to sort it out OK
Many Thanks....

Hi All.. in the last few days I have managed to sort out my modem designation with the help of the BT website. I now know that three mobiles and three other appliances are using 2Ghz, but my IPad is using 5ghz. Is this because the pad is maybe an 802.11a device? I only have one SSID number covering both frequencies which suggests that the modem decides which frequency is needed...any help with this would be appreciated

No, 802.11a had been long superseded by the time the first iPad was released. 802.11n and 802.11ac can both support 5Ghz in addition to 2.4Ghz so it'll be using one of those standards depending on it's version.

suggests that the modem decides which frequency is needed...

I don't know the technical details but it'll be a negotiation between the device and hub if the user hasn't set anything specifically. The marketing blurb is likely referring to some feature that previous versions of the hub didn't have they helps the negotiations.
