Tx signal

RouterOS Wireless Networking

Hi all. Before i begin i need to mention that I have limited wireless networking knowledge :confused:

I am trying to connect to a community wan using a 5.8ghz antenna and mikrotik rb433. I have a somewhat limited line of sight to the tower/highsite that connects the network together. From my understanding thus far, any signal below -75db is deemed acceptable to connect to this network. I have signal of around -67 to -70 when I scan this network in Winbox.

According to this I believe I should be able to connect to the network somewhat decently. However I cannot access or do anything on the network. 95% of the time trying to access the networks intranet sites, results in timeouts.

What I have noticed is that the tx signal is still bad, I am getting anything between -79 and -86 while the rx signal stays between -67 to -70. What could cause the tx signal to be so much higher than the rx signal? Is there anyway we can correct this?

Many thanks

Hi, this is a snapshot of the connections status in Winbox. What is a good signal to noise reading? And is this ccq alright? it sometimes reads 1/60% or 2/60%?

Thanks

What antenna’s are being used, max / min distance between high site and customers, what radio card is being used on the 433, what CPE’s are being used, how many customers are registered to the AP, how many have limited line of sight to the AP…

Okay this is as much as I do know, the antennas used are 27dbi 5.8ghz Grid and Radio card is R52, all members connecting to the highsite should more or less be using the same equipment. I do not know how many are connected to AP or how many have limited line of sight.

Your signal is to low. Also R52 is a very old low power card so it’s normal tx signal to be low.

Is the Grid used at high site or by customers or both ?

Unfortunately I do not know any technical specifications of the highsites..

I have seen anything above -75 will start to give problems with nv2.

for nv2 if would say if you can go below -70 your issue should be sorted.

Unfortunately I do not know any technical specifications of the highsites..

Your signal level for rx and tx is 10dbm apart.

I see the output power for the R52 is only 19db.

from the looks of it the ap you are connecting to is transmitting at something like 27db.

So if possible, get yourself something like a rb groove.

Isn’t the rbgroove SISO? I say go with a MIMO device. Get an SXT or one of those Dynadish antennas.

Mmm, don’t know too well which equipment can and can’t work on this network and don’t know enough about networking myself to try figure it out. All I know is we bought the antenna and routerboard, as a bundled combo and as far as we know this is the standard equipment in use for all clients of the network. I should mention the equipment was pre-owned, is there any way that possible antenna damage or deterioration could be the cause of the poor TX signal?

Many Thanks
