Thanks, Wonk. Re: the number of nines... "Certainly, I take Frank's cautionary comments to heart. However, if one could get availability up to 4-5 nines via a mesh configuration, I think they've got something here... I'm intrigued." So, too, am I intrigued. Now that you bring up the meshing alternative, admittedly, even more so. I hadn't considered the added benefits allowed by self healing features in a mesh, at whatever layer, but even so, these capabilities will do little to offset periods of harsh or overly inclement weather. I take the distance claims with a grain of salt. IR mfgrs are known to publish their maximum distances achievable, and their highest data rates achievable. But when these parameters are juxtaposed, you need a sliding graph to demostrate what it is that you can achieve in the way of distance at every level of desired throughput. I've been involved with systems that boast (indeed they performed at) OC-3 155 Mbps over distances of 200 to 400 meters. 10 Mbps at a more lofty 1,000 meters, and so on. Have you come across any such sliding graph from LU in this context? Curious. Concerning security, I was involved with some Mergers and Acquisition folks during one of my IR exploits who were concerned that window shots could easily be compromised through tapping reflections off the glass window in front of each gun. After much agonizing over this, and after calling in a couple of NSA graduates to tell just how this would be done (graphically, telling that these guys had done it before), we decided to abandon this approach at the clients insistence, despite fully encrypting with DES at the time, at the T1 rate. Paranoia and FUD, bolstered by ever-increasing deciphering capabilities, thanks in part to Moores Law, and some bona fide testimonials like the NSA geeks provided, tend to affect IR assuredness from a security standpoint, as it does to Spread Spectrum uptake in highly similar way, as well.
