Yes you are right, had a little look on the net to confirm they do indeed have 25MHz with BT holding the other 20MHz.
Looks like I have been pretty deluded with my assumptions for quite some time over this. Don't know how I got this wrong all along haha.”
Don't worry about it, we've all been there, technology can get pretty confusing
Paired spectrum means that downlink spectrum is paired with uplink spectrum, so the phone can both download and upload at the same time using different parts of spectrum. This is called FDD (frequency division duplex)
Unpaired spectrum means the downlink and uplink share the same spectrum, so the network can configure the time slots to say make 5 out of 7 time slots downlink, and 2 out of 7 uplink. This gives slower downlink speeds but allows for more capacity to be allocated for uplink. This is called TDD (time division duplex)
I'm sure someone will be along to correct any mistakes if I've made them.
