Doing this On the same frequency is remarkable. but the gains they are claiming can be had right now by using TWO frequencies. Transmit on channel 1 receive on channel 12.. t
This might be problem if you want mesh network with many (n>2) nodes. They (mostly) want to hear each other.
Anyhow, with 100 dB (10 000 000 000) times stronger transmit signal I somehow doubt if geometry of antennas can be accurate
enough to keep it working with changing temperature, humidity etc. over MHz of bandwith.
Maybe with heavy DSP processing and continuos monitoring?
Compensating for scattering of own signal, and all reflections from surounding objects?
On top of it, we normally use MIMO: so you have to do it on 4 receiving antennas
Even with MIMO 2by2 we might double channel capacity in perfect (MIMO perfect) radio conditions.
Yes, it is possible in the lab. But mass products?
Ah, back to good old Shannon: just double the bandwith.
