Hi there everybody. I have a connection between 2 buildings, in building 2 there is 2 ip phones that connects to building one via port 6000udp.
Building 2 is on a higher ground than building 1. I did managed to get ccq to 99/99 by setting data rates to 6/9/18. When there is a slight breeze then the ccq on the rx side wil jump between 99/53/36 and so the data throughtput will decrease to 6mb/s.
I just would like to know wil this cause lagging or higher pings if ccq jump up and down.
Thanx
yes, packet loss causes low ccq, lagging and high ping.
detail more your system (distance between buildings, frequency used, antennas, radio cards)
It is rainy weather here today so the statistics may differ from when it is sunny or windy.
So far i did not had any disconnects or any timeouts. I am also using qos rules and qeues.
I know that 2km is too close for using 27dbi grids and 25 db cards, there is also a few tress in the way that may be causing the cq problems. AP2 is located on top of one of the company’s managers home and it is on lower ground than the surroundings.(On the river bed)
Later that day i looked at the registration table again and this is what i saw.
The signal from ap2 to ap3 has weaken a little but stil does not disconnect.
With 2Km distance with 27dbi grids my guess is signal should be low 40’s and not 60 to 70dbm range also your signal to noise ratio should be 50+ and not 11 to 28, you are using the same polarity at both ends vertical to vertical or horizontal to horizontal and check your alignment, your frequencies 5180 and 5260 are too close move further apart, what is the distance on the mast between each grid, if there is tree’s blocking or causing freznel issues then consider increasing height of mast or moving the AP’s clear LOS and no freznel zone issues is a must otherwise you have very bad AP’s?
Hi there after some strong wind and lots of rain i had to change the freq on ap1 to ap2 to 5660 5ghz 20mhz. The dbi is about 31 to 42 now. But the link between ap2 and ap3 is stil ±10dbi.
The two grids on ap2 is about ±600mm apart.
On sunny days the signal is to strong(rx streing is about -46) and on rainy days the signal is too weak(-86). But only at some times. i dont get any delays or lagging because im playing online games in the evening.
Your signal should not vary by 40db unless the grids can move on the mast i assume on the rainy days it is also windy and causing movement, if you are using the same polarity for the grids in ap2 then move them as far apart as possible, i don’t understand " ap3 is stil ±10dbi."
What is you signal to noise ratio + CCQ + Signal between Ap1 to Ap2, and from Ap2 to Ap3
Have you tried ligowave link calculator http://www.ligowave.com/linkcalc/
I have setup a backbone link so when the first link might be down due to power outage or bad weather then the second link wil be used.
Cheers
