Hi Tech Bull, The systems we have been looking at so far are in the 2.4 and 5.2(?)Ghz range and are part of the unlicensed spectrum. These are lower powered units and we are limited to a range of about 20 miles max which is just fine for the ranchette setup around here where homes are typically set on 10 acre parcels. [News flash: I just glanced at the CNBC ticker and AMCC is up over 9 bucks at this point, new all time high! Kinda raises the spirits a bit. Sure more fun to look at than my MFNX.] Ok, so back to the VoIP solution. Each of the vendors I have looked into (Aironet, Brezecom.com and KMX.com and others) are using a SCDMA. The KMX link is designated to be the backhaul and connection to the 'bone. They are now served by Verio but are negotiating with QWST for a DS-3. Bend has pretty small demands for bandwidth so far so this will be quite adequate. My present ISP EmpireNet, has just installed a DS-3 onto the US Worst backbone and it's going to take them a while to fill the pipe. I've just started to negotiate with the KMX crowd and they are an interesting bunch. They are just moving into commercial comms, having spent a good long while in spook stuff for DOD and some of the national labs. Their frequency is 2.4Ghz for the backhaul as would be the links to the individual nodes. I'm going to have to look into this. Intuitively it seems that it would be better to have the backhaul at a different frequency than the local network, but then, I don't know enough about the spread-spectrum algorythms yet to make a qualified judgement. TTBOMK, there are no LMDS vendors in this area at this point that I can make use of. There are a couple LMDS links I know of. One is worthy of note. Formerly, the Internet connection between the Descutes County Library and the Central Oregon Community College Library was 16 hops. Pretty interesting for two buildings which are 2 miles apart. An LDMS link via BendNet, another local ISP reduced that to one hop. Unfortunately for my purposes, that setup is on the wrong side of the Butte and inaccessible to me due to the line of sight requirements I face. OC-3 links? I guess the DS-3s are about equivalent. I am thinking about a whole lot less bandwidth for the 24 node network I'm proposing. Unfortunately, at this time my component list sums to about $7,000 per node and this just wont work as a business proposition. So I'll wait for the next generation of wireless gear (9 months, according to Carly Fiorina, Prez of Int'l Sales, Lucent) and try again. I have heard that AT&T has recently had a price breakthrough and are now setting up an experimental wireless 'last mile' at a cost of about $750 per customer. That kind of infrastructure cost makes sense. I've got a ways to go yet. Thanks for your interest, hope I haven't bored you too badly with my details. Re: PCM-Sierra, I'll do some more DD and let you know what I think. Re: LU and McGinn, what an awesome thing to watch this old bureaucratic behemoth turn into a dancing entrepreneur. Best, Ry
