I have a simple policy 1 X radio card = 1 X routerboard (433ah), and use something like RB750 to combine the sectors.

Microcells - is the sectors of your AP feeding these microcells direct or do you use a PTP link ?

Are you using dynamic ACK timeouts ?

One reason for the possible P-throughput value of 20,769 kbps on one radio and P-throughput value of 7,359 kbps could be that the 7,359 kbps radio is connecting at a lower modulation speed rate (6 Mbps) and the 20,769 kbps radio is talking at a faster modulated rate (35 Mbps). OK but strange i trie...

The issue would appear to be SSID, as the CPE appears to be looking for AP with last SSID it registered to, If only the cpe would flush SSID and then scan from the connect list? perhaps a script is needed to achieve this (OS V3.30)

n21roadie

There is large natural attenuation on 24GHz, link for more than 40miles is brainless idea

Lucky I did not purchase 24ghz equipment first and then asked questions ?

Can i have more info on the Long Range Airone M7, how good does it work, does it operate in license exempt frequencies?

n21roadie

Do you have line of sight between the radios? At 40 miles on flat ground, you are gonna need some BIG towers.

Mountain to mountain

n21roadie

Anybody using 24 GHz unlicensed for backhaul, what is the best and cost effective for long distance > 40miles ?

n21roadie

Bring your OS versions to the same level and things will improve. Add in loopbacks and they will get even better.

I would ask others for their opinion on that statement, is it just a fix for a issue or a possible tweak?

n21roadie

You may also want to not let the radio change the modulation scheme if you are looking for a stable link for voice. i.e. leting only the rate 24 on the AP then the AP will use only 16QAM and probably will hold stable at 100%/100% rx/tx CCQ.

Does this apply to Mikrotik - If yes how?

Have you tried testing at say 10kms and then at 20kms and finally 37kms comparing bandwidth, this eliminates any radio card issues and location, You mentioned a clean frequency usage scan but be aware the scan only displays frequency usage by 802... compliant gear and not the non compliant stuff, sp...

Well neighbour ( ye were lucky on Sunday in the replay but we (Limk) will win next match <g> ) I would like to help out if i can as i will shortly have to install a 70Km+ link, Have you tried v3.30, and TCP instead of UDP for bandwidth testing, Have you spaced the parabolic far enough away from othe...

433ah using version 3.30 + XR5 card, After system reset on reboot if I delete or use the default configuration (IP address 192.168.88.1/24 is on ether1) and just enable the wireless card and do scan then only 3 of 6 devices I know are present will be found, However if I run my generic CPE script the...

As i haven’t used these before but my comment is, I generally don't like limited bandwidth spec on a unit in this case the bandwidth quoted is 5.45-5.9 for the parabolic, and doing a full bandwidth scan on this unit could give misleading results ? 28dBi may look good but even when a low loss link rf...

Can I ask to Optimize network for VOIP has every device in the network chain be configured ?

Since I cange all my 18V PSU to 24V I don't feel requirement for redundant power supply solution )

You say changed power supply from 18v to 24v, Are you now running all of your devices from one single 24v power supply,
or have you a 24v power supply for each device,

If you not exceed Absolute Maximum Ratings it's very stable. Regading ralay devices all this devices have bad MTBF rate. And I am not use it for any serious application.

This is good news, can i ask have you have tried this method and works for you, thanks

Thanks for replies, The restlesspowerbox features are impressive but I did not read the most important requirement that is redundant power supplies, If the power supply goes down you lose all the devices that were powered from that unit?, The WebRelay looks promising, Ideally I suppose I am looking ...

Thanks , but the item has a bad review by previous customers ?

I have a power supply for each mikrotik device at the AP's, was thinking I could power some, say 4 units from one large power supply but am worried about the obvious if the power supply fails, then by that example 4 units are down, So I am looking for dual power supplies if one section fails then th...

Hi,

How do I allocate bandwidth priority for the allowance for VOIP calls, If at the CPE the customer is uploading/downloading at max, I want if the customer attempts to use VOIP, this call is allocated bandwidth for the call regardless of how much the upload/download is maxed out.

I am running out of ports on a 493ah and would like suggestions on what Mikrotik device is the next step up from it,
the 493ah is used as a switch to combine AP'S + PTP's, with some of the ports are routed and some bridged.

The reason i ask is on TV UHF frequencies the rotation of the blades cause all sort of interference, even to households with wind farm at rear but pickup tv signal from house front, this happens when the blades are rotating on a particular axis,
