First, there is NO "inter-band, dual-carrier" FDD-LTE in operation. Secondly, the variant of LG Optimus G, E971, from Rogers ONLY supports LTE Band 7 (2600) BUT NOT LTE Band 4 (AWS) that Rogers LTE is currently using.
Though Rogers has 20+20MHz paired in the BRS spectrum for the LTE service i.e. LTE Band 7 (2600), there is NO LTE UE Category 4 device on the market that would make use of the 20MHz bandwidth that will bring the full potential of LTE Category 4 with the downlink up to 150Mbps. All current UE Category 3 devices can only deal with 10MHz of bandwidth.
As for the 700MHz spectrum... if Industry Canada follows the steps of FCC in the US, it will be chaotic with different blocks of 6-12MHz!!! »www.ic.gc.ca/eic/site/smt-gst.ns···960.html If IC decides to go with other options, then we pray that there will be compatible devices on the market for us!!!
Right now in the US, there are different 700MHz bands... Band 12, 13, 14, 17... Qualcomm and other chipset / baseband vendors have yet to offer interoperability in mobile devices that can support all of the 700MHz bands. I hope that they are not just talking on papers but commercially available in volume to handset makers... »www.fiercewireless.com/story/qua···12-06-05
