Currently i am using Mikrotik Router and Smartbridges AP using omni antenna for my clients. The problem is it could only support 2 clients. When i tried to add another client to that AP, the ping time becomes more than 100 ms (normally <10ms). Now, i am thinking of using another AP, please give me some suggestion on product. Is it better to use routerboard or CPU?
My friend told me to attached wireless card on Pentium IV CPU and attached it outdoor on the tower (about 25meters high). Because he doesn’t give me any detail instruction, i am curious of how he done that. Because on the rough outdoor condition, anything could happened, i don’t wish to play with electricity Had anyone ever done this? Please give me detail information about this.
Hi there! I happened to ONLY use PC’s as servers on High Sites. I tried several things in the passed. I started with RB220’s, then I used a PC with prism2 pcmcia card, with about 6m LMR400 between the SENAO AMP and Injector. Worked much better than the RB220 option. Then I put a Senao AP on the top, connected with 500mm LMR400 to injector, run CAT5 to PC etc. WORKED THE BEST, only prob is, when I reached more than 40 users, the AP couldn’t take the load anymore. I now have two options, either put a RB230 in the place of the AP, OR, put a PC on the rooftop. I was told the RB230’s can handle up to 40 clients per prism2 card and up to 60 per atheros card. I bought two new atheros duel band miniPCI cards and a riser board for my RB230. I tried several cards, 2.4GHz 802.11b atheros, prism2.5, and those duel band athero’s ones. I had them all running in the same board, all AP’s, all diff channels (and I played around with the channels too). Then I took my notebook, walked a certain distance, while testing pings and comms on each diff SSID. The prism2.5 allways had the strongest signal, but it’s comms jumped all over the show. The 2.4GHz atheros (200mw too) also had very good signal all the time, comms also jumping all over the show. Then I tried the duel band ones. The signal wasn’t allways the greatest, but it was STABLE. The comms was ALLWAYS better than the signal. The pings were allways more or less the same, and went higher and higher as the comms dropped. With the other cards the pings went all over the show. I wish I could try the Atheros CM9’s, but noone had stock. I made my decision to put my RB230 with miniPCI cards on the roof top, and try to move away from amps too. I am supposed to be doing this today (its now 1am), but it seems like it might be raining, and im supposed to be sick in bed. As soon as I did it, ill put an update on the forum to tell people about my success or failure!
Hi, thank you for your posting, i have read many article posted in this forum, 80% of people says “DO NOT TRY USING ANY AMPS”, they says that it would cause great interference. Will you try using RB 220 with atheros or prism without using any amps? Please post me with the result.
Hi again! I havent installed the new system yet, still a bit sick. But I kept testing it in my home environment, and the Dual’s REALLY works sooo much better. Regarding the AMP, a AMP boost whatever it picks up. It also boost noise. You do get good AMPS which filter the noise out, like the Senao one I’m using. Rather, it SUPOSEDLY filter the noise out… I have been fooled with wrongful advertisement before, but apparently the Senao ones does filter out some of the noise. As soon as my site is up, I’ll post here again! Im very curious myself how this is going to work!
RB530 with a Ubiquiti 400mW SR2/5 3’ run of LMR400 to sector/omni.. Cat5 down to PoE…
That’s the best way to do it in my opinion.. I’ve dealt with long LMR runs and AMPS and its not the best solution.. To many physical devices to fail or catch water.. and with the 400mW ubiquiti’s you don’t even need an AMP..
for our microPOP’s we use three 14dB gain 120 degree sector antennas w/ three routerboard 530’s w/ SR2’s.. then we have another RB530 for a PtP back to the tower w/ a SR5 and a 26dB radome dish.
I wish I had a picture handy, it looks really nice. The routerboards mount right behind the sectors to give the minimum amount of LMR we just take the pigtail from the antenna and plug it right into the RB530.. very little signal loss and figure roughly 50 users per RB..
If you do the math thats about 40dB of total output power, after connector/cable attenuation your looking at 39.5dB ~ 8-10Watts…
Might upset the FCC, but they’re not paying attention anyway… Plus you can turn down the output power on the cards if needed..
Had anyone ever done this? Please give me detail information about this.
