I posted here in early April as I searched for replacements for Cisco WGB-352 workgroup (8 MAC max) bridges. I just gambled on six Senao / Engenius NL-2611 CB3+ Deluxe from www.bizsyscon.com. Official site: http://www.senao.com/english/product/product_wireless01_outdoor_1.asp?tp1id= 02&tp2id=02&proid=000064 After only a few hours of study: Pro: Cheap. Only $740 shipped for six, or $123 each. Seemingly high power. Works as a bridge to a Cisco AP-352, works as a bridge to another Senao in 'point to point' mode. One RP-TNC antenna connector, just like Cisco WGB. PDF manual isn't bad compared to many. Con: I want to watch throughput with MRTG, but haven't found any SNMP (as the 2511 seemed to have) nor are there enough useful values in the web interface that a little scripting might snarf. All you get in the web interface is link quality percentage, current transmission rate, and a table of known MACs on the bridge. Wants a cross-over cable to connect to a PC. Plus: It comes with a 6 foot red snagfree crossover cable. Wish it wanted straight-through like a WGB-352, or had a cross-or-not switch like the WET-11. The firmware upgrades are somewhat crude: you need to edit the 'do.bat' file so 'tftp' (not included) knows your IP address. I tried upgrading the firmware from 1.8.0 to the 1.9.0 (3/5/2004) on Senao's site, but I couldn't get it to take, so I don't know what I'm doing wrong or what might be in the new release. 'do.bat' sends 'dualmode_sp.bin' 259K, but there's also 'ap.elf' 438K that's not mentioned in 'do.bat'. Any tips would be appreciated. Tech support / downloads section on Senao's site is minimal, and the firmware 'readme's - if any - are more brief than that. Not much on http://www.engeniustech.com/ or Broadband Reports either. - John ------------------------------ Message: 2 Date: Fri, 14 May 2004 21:32:39 -0400 From: "Donald Day" <[EMAIL PROTECTED]> Subject: Re: [BAWUG] Engenius/Senao AP/Bridge - any comments? To: <[EMAIL PROTECTED]>, "John Foust" <[EMAIL PROTECTED]> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="iso-8859-1" I have 2 CB3-Plus's. I too feel that the lack of any type of usable interface makes this piece of hardware the most ugly prom queen ever. Nothing to look at and frustrating to deal with but she does "put out". That's the only thing going for it and going forward that won't be enough to keep me a customer. Good for a few cheap dates and that's about it. I wanted to use them for a long distance shot (5.5miles with minor foliage) with a couple of 24db grid antennas (probably illegal output values). However the lack of software features keeps them relegated to a close proximity solution. Engenius is such an oxymoron in this context. I'd name this line of hardware "The knuckle dragger". If they could ever spend a few bucks on SNMP and useful interface John Chambers would have to take notice. dwd ----- Original Message ----- From: "John Foust" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, May 14, 2004 6:47 PM Subject: Re: [BAWUG] Engenius/Senao AP/Bridge - any comments? > At 11:15 AM 5/9/2004, DaveC <[EMAIL PROTECTED]> wrote: > >I'm interested in the Engenius/Senao SL-2611 200mW AP/multi-client/Bridge box.

You're close to legal (probably are for a 24dBi (dBi, not dB) antenna on a 23dBm radio in terms of EIRP for a PTP link. You'll need 1dB of loss somewhere between the two to stay 'in-bounds'. If its a PTP link then you're allowed 30 - (antenna gain - 6) / 3, so 30 - ((24 - 6) / 3) or 24dBm! By the time you account for coax losses, you're probably more than fine. You may *not* be legal in terms of out of band emissions when operating close to the edges of the band (say, on channels 1 or 11.) > However the lack of software features keeps them relegated to a close > proximity solution. > > Engenius is such an oxymoron in this context.

(-: Well, I also decided that it was too expensive and decided to make my own. I bought the connectors and crimping tools from Electro-Comm: http://www.ecommwireless.com $5 for the N male and $6 for the Orinoco connector. About $35/ea for 3 crimping tools. I scrounged the LMR-100 and shrink tube. So far, we have about $12 in parts, ignoring the crimp tools. However, what killed me was the time it took to make a single pigtail. I didn't buy a cable stripper and had to do the cable prep with a pocket knife and diagonal cutters. Figure on about 30-45 minutes each (including testing) and ruining a few connectors before announcing success. Crimped connectors and nice, but you don't get a 2nd chance if you mess up the crimp. My guess is that I would have been better off buying instead of building my own. Lately, I've been buying from: http://www.fab-corp.com/K1.htm $19 for a 12" Orinoco cable. > When connecting an antenna to the orinoco card, is it okay to use > "pigtail" (say, LMR100A) for the whole length, or should a short pigtail > be used to convert to some other kind of cable? No. LMR-100 is good coax for short pigtails, but not long runs. LMR-100 is about 19dB/100ft or 0.19dB/ft. 3dB is half your power so 15.7ft of LMR-100 will eat half your power. Actually it's a bit worse than that as each connector pair will eat an additional 0.5dB. The whole idea behind a pigail is to provide a flexible connection to your LAN card so that the big, fat, heavy, and low loss coax cable to the antenna, doesn't break off the connector on the wireless LAN card. > I see all of these 12" > pigtails offered -- does that mean these people have the antenna within > 12" of the radio adapter? I think I'm planning to get a 60" pigtail, > since that seems to be a convenient length. No. Antenna runs should be made with LMR-400 or LMR-600. LMR-400 is 6.8dB/100ft or 0.068dB/ft. Much less attenuation than LMR-100. -- # Jeff Liebermann Liebermann Design 150 Felker St #D Santa Cruz CA 95060 # 831.336.2558 voice 831.421.6491 digital_pager AE6KS # [EMAIL PROTECTED] http://www.LearnByDestroying.com ------------------------------ Message: 6 Date: Fri, 14 May 2004 23:39:34 -0700 From: "Matthew Kaufman" <[EMAIL PROTECTED]> Subject: RE: [BAWUG] pigtail questions To: "'Jeff Liebermann'" <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="us-ascii" Assuming your numbers are right (I personally think the connector loss number is probably too high *for a properly installed and maintained connector*, but the argument works better if I just use your numbers) 12" of LMR-100 + 48" of LMR-400 plus the connector pair to hook them together: .19 + (4 * .068) + .5 = .962 60" of LMR-100: (.19 * 5) = .95 The difference in loss is negligible, and in the favor of the single 60" piece of LMR-100. The single piece of LMR-100 will be cheaper than a 12" piece of LMR-100 *and* a 48" piece of LMR-400 *and* the connectors necessary to hook them together (remember you need one male and one female (less commmon) N connector to do it without the extra loss of a double-female adapter), plus you'd need to keep that connection weathertight. I stand by my original claim that at 60", the single chunk of LMR-100 is the right choice, but at 60', something bigger (at least LMR-600 at these frequencies) is the right choice.
