Re: [WISPA] Longest 18ghz link
I already have the 18ghz set sitting on the shelf, that would be the only reason to use it. Here's the interesting thing about a link that long: 2ft dishes = 99.9955% uptime (23 minutes per year outage) 4ft dishes = 99.9992% uptime (5 minutes per year outage) I can live with 23 minutes per year if I can use 2ft dishes.

Re: [WISPA] RF propagation map: WiFi vs WiMax?
802.16e in 5.8ghz would be absolutely the biggest waste of money ever as you wouldn't get a true mobile network but your network costs would be around, yaknow, 300k for a market of 20k people for just BASE station equipment. The way to go if you are really worried about upward compatibility ( and you own licenses or want to lease spectrum ) is to build a MOFO network using ATCA solutions, but still you are talking for just 4 sectors of Wimax with scaleablity to multiple bands and sectors, 50k per base station to start. The key is going to market with a solution that has both a SDR system but low cost initially. - jeff On Oct 4, 2007, at 8:23 PM, Senthil wrote: We did consider deploying Wi-Max 802.16e (802.16d totally out of the question) in 5.8 GHz but checking on the technical aspects of the standard Wi-Max still seems to be rather immature as most aspects are similar to 802.11a/g. Then again this applies only to the initial Wave-1 compliant Wi-Max devices but once wave-2 standardized equipment comes we should have smarter antenna systems (MIMO,beamforming) with which we will definitely get a better performance. So for the time being I think in terms of performance, pricing and technology it's better to stick to Wi-Fi!

Re: [WISPA] RF propagation map: WiFi vs WiMax?
All, Bear in mind, Clearwire uses their own base station technology, which is mostly Nextnet base stations ( now motorola ) . Nextnet's performance is not wimax, just really high power base stations and CPE. 4 QAM / 2 WATT output power / 8dbi directional antenna on the CPE and I think around 10 watts on the base in power? ( originally was nextnet, then mccaw bought them for 50 million, then sold it to Motorola in exchange for 500 million in investment ) - Jeff On Oct 4, 2007, at 11:04 AM, <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> wrote: 2.5 has great range & penetration. ClearWire, as an example, had solid indoor coverage 2 miles away. I live in an apartment complex thats "out of coverage area", and it still works - I'm in the bottom floor of an apartment complex, my unit has another unit behind it, a 4 acre forest conservation area, I stick it in my window, get 2/5 bars on it, and still get 1Mbps... Outdoor, could be many more miles, but the ClearWire indoor-only self-install business model seems superior to all other WISP models, unless you're selling a super-premium business service (fiber/T1 replacement). We basically sell Clearwire for all residential, and use our own wireless network for premium business customers only (149/month minimum).

I spent a little bit of time researching WiMax, but decided I would be unlikely to have a license and to just go with what I have that mostly works (unlicensed). But I would like to know what WiMax means in a rural, tree filled environment. As a novice WISP (about 18 months now), I can only hope for good coverage with 2.4GHz to maybe a mile. A rare house might have LOS farther than that, but generally there will be enough trees in the way by a mile to block my signal. (this is using farm grain legs/ silos for the AP, so maybe 150' max AGL) If I switch to 900MHz, maybe the distance gets out to 2.5 miles. Would a 2.5GHz Wimax AP push the signal much better thru trees? I suppose it would make a difference what was at the customer end - a laptop with a WiMax card vs a fixed, outdoor radio. And does AP height help a lot? I don't see an advantage to paying commercial tower rates to get above 200' in my situation, but maybe that changes with WiMax. -- -- ** Join us at the WISPA Reception at 6:30 PM on October the 16th 2007 at ISPCON ** ** ISPCON Fall 2007 - October 16-18 - San Jose, CA www.ispcon.com ** ** THE INTERNET INDUSTRY EVENT ** ** FREE Exhibits and Events Pass available until August 31 ** ** Use Customer Code WSEMF7 when you register online at http://www.ispcon.com/register.php ** -- -- WISPA Wants You!
