Hi. I just entered working in a new company and they have asked me to set up a wireless link between two points, 800 mts away from each other (about 2400 fts).
We have 2 wap11 version 2.6, 1 VAGI 16 dbi antenna and 1 12 dbi pacwireless omni antenna with pigtails. They're all from www.fab-corp.com. I'm new in this wlan world. All this equipment was bougth by the last engineer who left the company a few days ago. I've made some tests but they haven't worked at all..They work perfect indoors and even interoperate with other Planet wap1960 AP we have. We tried to make them work in a 500 mts (1500 fts) link from the window of a 4 stories building and the roof of a 13 stories building. The antenna says it has "3 dg electrical down tilt". My questions are: I'm not sure why it does not work. i live in Cali, Colombia and we don't have too many 2.4 ghz, microwave devices or simmilar in this area.I see some trees a about 40 mts from one point. I read that about 60% of the first Fresnel zone should be without obstructions to have a link. Is there a way to easily calculate the width of this fresnel zone ? I'm about to perform other tests in other environment so i would like to know how to know the maximum distance an obstruction could be from the LOS. I 've read almost all the posts in this lists about wap11. Many people say they're very bad in long ranges. But why there are some guys with 8000 mts and even 26 miles (in maui) with wap11 and no big problems ? I see that the most of the "bad" posts are from 2001 and 2002 when there wasn't version 2.2 nor 2.6 yet. I tried only ap and ap-client modes. What's the exact difference between a link this way and a bridge link ? (besides having the ap<->ap-client mode with cappablity for accepting other wireless clients). Unfortunately we can't return them. It's southamerica and the shipping is about twice the price. I need to make them work. I'm really new in this. I would appreciate any help, suggestion, and comments about this problem. P.S.: The VAGI antennas (from pacwireless) say they have vertical and horizontal polarization depending on the way you grab it. The omni antenna say something like that. What is it ? thanks for any info. Julian -- general wireless list, a bawug thing <http://www.bawug.org/> [un]subscribe: http://lists.bawug.org/mailman/listinfo/wireless
