richy Posted January 3, 2014 Share Posted January 3, 2014 Daft question but is it possible to deploy FDD LTE in an asymmetrical manner. i.e. (5+5) x 5 or 10x5 ? Is the licencing restrictions more of a issue than technical considerations. I understand that MHz for MHz upstream can deliver less MBps in practice but there is normally a significant disparity between upstream and downstream usage but spectrum allocation with FDD is equal in many cases resulting in some amusing speed tests where you see 2mbps down but 6mbps up (this could also be caused by congesting on the backhaul). I recently got a result like this on tmo lte. It seems to a layman that TDD does have the ability to change the balance between upstream and downstream to better fit the usage profile as compared to FDD but is there a way of deploying FDD asymmetrically rather than the current symmetrical profile? Apologies is this is a silly question Very interested in your thoughts! It just struck me as one way of better utilizing spectrum given the very high costs of spectrum. I wonder how much this was considered when spectrum was auctioned? 1 Quote Link to comment Share on other sites More sharing options...
