Hello, I have successfully installed 2 RB333 on each there is a wireless minipci card and each rb333 is located on a different building. The distance between the buildings is about 4 KM. I used 24dbi dish antennas. The link behaves perfect when it doesn’t rain, however when it rains it is not too reliable. What tests / modifications should I do to ensure that this link behaves better.
The frequency I am using is 5.7Ghz
Regards,
Ignacio
What type of radio are you using?
What is your signal strength?
What height are your antennas?
Do you have clear line of sight?
What type of radio are you using?
Atheros AR5413
5745 Mhz
What is your signal strength?
I Will post this later on because the link is down
What height are your antennas?
One is on top of a 10 story building which is on top of a 400 mts hill
The other one is a 8 story building
Do you have clear line of sight?
Yes
5413 doesn’t tell me anything. What make/model are the cards?
The info that is shown in the winbox about the card type is: Atheros AR5413
Is this enough or you need more info. Where can I find more info about the cards?
Umm… it sounds like you purchased this as a kit already assembled? Go back to where you bought it and ask.
The wireless card:
Engenius
Model name: EMP8602 Plus-s
That is a horrible card to use for 5ghz. Get a R52h or XR5
Thanks for the info, which one is better for distances no longer than 20km?
For antennas I use dishes 29dbi.
Thank you,
Ignacio
Continuing with my posts, I am including some printscreens with the info that follows:
I have two buildings connected 4Kms appart (aprox)
signal strength -88 dbm
Noise Floor -95 dbm
overall tx ccq oscilates from 10% to 50% and somtimes the connection is dropped
I should have nstream disabled right?
how can I optimize this
where should I make the changes in winbox
thank you for your help
Ignacio
To start, you need to upgrade your ROS to the latest version.
Your signal strength will not give a reliable connection. Buy yourself a couple SR or XR5’s and you will be fine.
Is the signal too strong? or is it just that the minipci cards are not good?, Can I modify manually the signal strength?
Regards.
I’m I better off with a R52H from mikrotik for a 4km link?
The 8602 cards are garbage for 5ghz. A Ubiquiti XR5 has far more power output than the R52h
Thank you for your support, I will let my supplier that what he sold me is pure junk!
Thanks Bill. Informative post.
These are the cards i have for my backhaul and from experience I agree they are SHIT> crappy performance crappy throughput… Going to be upgrading to Xr5’s or R52’s… those 8602’s are only good for CPE’s maybe… Thanks for clarifying my assumption of the 8602’s though John. -Jordan
8602 are terrible, i use in some links rb333 with cm9 and 90cm dish for 50km with -60 signal,
Can you elaborate? Does it matter which particular routerboard? What difference does the firmware make?
We had a batch of 35 XR5 deployed recently across a mix of RB333 and RB411 and have had at least four failures in the first month. All units in metal housing, shielded cables, well earthed, etc.
We’ve got around 300 routerboards deployed now at varying firmwares and I really wonder if it is worth upgrading them all.
What is your data rate? ALso i dont understand how they go so far there only a 75 mw card… That is why i didnt buy them.. -Jordan
