Good points and… Good news! We have most of them covered: just because we showed the testbed in the lab does not mean that we have not done all sorts of experiments, indoors and outdoors, with good and bad weather, with obstacles and without, with distances ranging from less than a meter to several kilometers, and all not just sending “sinusoidals” or “random IQ samples”, but actually data-carrying frames at several gigabits per seconds. This requires tailored signal processing solutions and the equipment that you see it is a vehicle to implement the DSP and show proof of concepts. More good news: no, we don’t need 64 antennas, we can do this with one! Of course, having arrays will give us more flexibility, like, dynamic beamforming and steering, but at these frequencies, such arrays are less than one square inch! Obviously, all this is not something put together in a couple of months or years, but the result of over ten years of research. All the information can be found and back-tracked in the lab publications, and we always welcome visitors to see what is going on. Cheers.

I appreciate your advancements in technology, I smile when I watch your basic setup, and love the test instrumentation. Although your technology survives well within your existing environment, the challenge will be much greater when living in real world environments. What thought or testing have you conducted to address these type of issues? It’s great to build a simple test setup, but what are the transmit / receive limitations? How are you going to design a reliable system, Will you need to have 30-40 transmit antennae to cover the size of a football stadium? What about physical, objects buildings, hills, large waterways etc? Will this be a Direct fiber only customer system? Look out your window, what you do and what you don’t see will be the super challenge. Thanks.
