Interesting article from the recent IEEE Comsoc magazine. Table 1 on page 5 is an interesting comparison of how different players reach the magical '1000x' capacity increase. Even though Huawei shows 100x, which may be more realistic, the industry is sticking with the 1000x figure.
Qualcomm is touting a similar 1000x figure as I showed in a post earlier here.
Please make sure to read the comment from Kevin Flynn of 3GPP at the end
When I saw this picture above, I started wondering what LTE-B, etc. and started digging a bit deep. Came across this Ericsson presentation (embedded below) that shows the breakdown.
To just be sure that this is not Ericsson specific term, I also found a presentation by NTT Docomo (embedded below)
So I guess using LTE-B, LTE-C, etc. is better than saying 4.1G, 4.2G, etc. as we did in case of 3G/HSPA.
The presentations from Ericsson and NTT Docomo embedded below, available to download from Slideshare.
Recently when I added a presentation by NSN on whats coming after IMT-Advanced, it was very well received and has already had over 8000 views. There seems to be definitely an appetite for the future networks. Here is another such presentation.
