In LTE they talk about carrier a lot. It's not verizon, at&t and etc but seems to be different things. What does 'carrier' mean in LTE?
Carrier can mean two things in the LTE world:
I think the latter is probably what you are referring to and this is definitely what is meant when the term 'carrier aggregation' is used - this essentially allows LTE combine the data carrying capabilities of multiple 'channels' to increase the overall bandwidth either to or from the device.
