It says they have implemented a circulator on a silicon chip. That perhaps
would mean something like a Mimosa B11 could operate FDD. Not sure it would
be revolutionary for a typical licensed link, where there is probably no
obstacle to using a conventional circulator, plus I'm not sure they could
achieve the rejection necessary to operate at 1024 - 4096 QAM.
What is unclear to me from the article is if this is a passive circuit ahead
of the receiver front end or not. If it's an active cancellation technique
like XPIC, then rcv front end overload would still be a limiting factor.
I'm thinking the circulator is like the "hybrid" in a telephone interface,
originally a magnetic hybrid i.e. a specialized transformer, but then
integrated into subscriber line interface circuits with no magnetics, so it
could be miniaturized and made cheaply.
I would guess the main advantage of this technique is being on chip and not
using bulky, expensive circulators, it could be implemented on WiFi chips in
mass market devices.

Sometimes, I really don't know if you think through some of the things you
say.
Anyone interested in or using licensed frequencies, for one, cares.
People who would like much greater WiFi performance care. Cell
companies care.
This is tech easily worth many billions.

Sounds like it just adds FDX which "doubles" your speed. Who cares...

It's not going to have any effect on your frequency re-use, but it
should be able to drastically reduce your PTMP latency, improving
throughput across the board. Also, it could double your throughput on
your current RF licenses - before you were TXing and RXing on two
different channels - now you can TX and RX on both channels
simultaneously.
