Hi guys, just a couple of quick notes. The first is an answer to the last question:
Q: Is fog/rain the primary issue with the technology?
A: Yes and No, actually fog is the primary issue with optical wireless communications, rain is not a particularly major issue. Rain causes problems for the RF systems, not one that can't be overcome, but certainly one that causes grief (seriously impacts distances). With optical systems (lasers) the issue is fog and causes the same type of problems. The 2 make a very nice marriage of technologies however; when combined they offer and excellent all-weather redundant communications package.
My next point is that there is another thread here: Subject 33955
I just started it. It pertains to another new company, privately owned, called fSONA. I am the company's Director of Product Sales/Support and we are also in the optical wireless arena, however we are supplying a slightly different product from Terabeam, in that we are focused on the pt-pt market and can be easily incorporated into anyone's network, including Terabeam's. The reality today is that the bandwidth requirements that are being looked at, for the forseeable future, can gobble up pretty much all of what any of us can produce, RF included. The wireless market will need to incorporate a combination of optical and RF systems to meet that demand, in a reliable effective manner.
Salut,
