Re: [Banana] Proposed Charter for BANANA WG

Sorry for late reply.

The work here is highly political.

I am not intending to resurrect whatever.

But the bandwidth aggregation is a key issue in many contexts.

For the sake of the technical answer, here:

A recent modem announcement, claiming to aggregate 1GBps into an UE 
Category 16, using the typical 4G band 2.6GHz together with 3.5GHz 
(recently resurrected in some country for fixed mobile broadband) 
together with the unlicensed 5GHz band.

That 1Gbps is not necessarily the highest possible at that manufacturer, 
but is way above the current 4G+ deployments at 300Mbps or so.

That sounds really high compared to what single mobile user terminal 
could do in wireless.  But it's good to see.

802.11ax - I did not know it existed.  I am left at 802.11ad.

I would like to ask you which frequency band is 802.11ax working at? 
Which channel width (80MHz?) and what name of the encoder (FDD, TDD, etc.)
