We are using the alvarion breezemax and the redline redmax at 3.65GHz (all 802.16d). We think both of these are great. (We also tried Airspan, but did not come away impressed). For the stats I mention below, the clients are spaced between 0.1miles and 15 miles (15 miles is of course with LOS). Many of these are business T1s and high end residential connections. The highest download per AP we can get is 15mbps steady on a 7mhz channel and this can be up to about 10 miles or so. VoIP works great across the board.
>From what I understand the clearwire WIMAX 2.5GHz 16e network being tested in now Portland has about 120 base stations spaced at about 1 per square mile and can deliver max speeds to a single client up to 15mbps (fixed) and 6Mbps (mobile) as well using 10MHz channels. We are putting a lot lower density (1 every 3-4 miles) going after the fixed market (outdoor CPE). Even though WiMAX is pricey ($15k or so per AP) I cant say enough about how truly amazing we think it is for WAN applications. WiFi is still top notch for LANs though and the combination of the two is powerful. ty ----- Original Message ----- From: "Charles Wyble" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, September 18, 2008 1:03 PM Subject: [ptp-general] Re: Weekly Meeting, this Wednesday at Green Dragon > > Tyler van Houwelingen wrote: >> This scheduling in the WiMAX MAC allows us to have 50-100 clients on a >> single WiMAX AP with no fall off in bandwidth per client (up to the >> capacity >> limit of course > > What kind of access point?
