Model: WBS210
Hardware Version:
Firmware Version:

Hey guys,

 

is it possible to use 2 WBS210 for a long link with just one SISO ant2424b at each end?

With Openwrt it is possible to adapt the antenna diversity.

Cant find this option in the original firmware.

 

I think, just connecting one antenna and letting the second antenna connection without an antenne, could damage the amplifier, right?

 

Thank you

Sure, but IMHO the effort might not worth it. Why not use two CPE610?

Such an option doesn't exist in Pharos firmware.

Correct, it might damage the amplifier. I connected a smaller omni antenna to the second connector for termination:

@R1D2 , thank you for your answers.

 

About CPE's, I dont like this all in one devices and second, I have allready here two 2424b's.

 

I think, I'm not sure, if on the same device, one omni and one directional antenna are connected, the receiver needs to observ always both antennas, one after the other, means throughput will be smaller, than a receiver with just one antenna like 'GL.iNet GL-AR150-Ext-2'.

 

Are my assumptions right?

Absolutely right. The omni was only for termination, so MIMO doesn't work with this combination and the WBS falls back to SISO connection.

 

Albeit I like WBS much too, CPEs are really cool - they have very good built-in antennas covering long ranges. Of course, two TL-ANT2424B cover even longer ranges (up to 50km IIRC), but have a similar antenna beam width like CPE610 making it harder to align them. I also have two TL-ANT2424B - one still unpacked - and abandoned them in favour of two CPE510 (not CPE610, which should also cover longer ranges than CPE510).

I will get such a terminator for one of the antenna connectors, to not 'hear' the near stations.

I could imagine, that this will improve the resistance against interference.

What do you think?

 

Danke and best regards

Hello Eduard,

 

that's a good idea, I think a 50Ω terminator will prevent damage of the amplifier.

 

Wish you much success! If it works, maybe you can share your experience here? Would be interesting which range you can cover with TL-ANT2424B.

I have thought about the All-In-One solution like CPE610 and done some researches.

 

It looks like there is a similar product 'LBE-5AC-Gen2' from the competitor Ubiquiti:

 

https://www.ui.com/airmax/litebeam-ac-gen2/

 

With the same characteristics and similar price.

 

Asked here the guys from the Freifunk community for their recommendations:

 

https://forum.freifunk.net/t/planung-einer-point-to-multipoint-verbindung-in-ludwigshafen/21099

 

Their recommentation is clear 'LBE-5AC-Gen2'.

 

I know, I'm in the TP-Link community, but, maybe someone of you, had this 2 units already in hands and compared them?

 

Sorry for so many questions and thank you

Yes, they have been similar in Gen1, but differ completely in Gen2. AirOs Gen1 had exactly them same functions and menu structure as Pharos on CPE610 still does. TP-Link and UBNT probably did buy the software from the same third party vendor (only guessing, but both firmwares were identical except for the spectrum analyzer function, for which IMO TP-Link's spectrum analyzer works better - I never could manage to get the UBNT spectrum analyzer working due to its Java dependency).

 

Personally, I did sell my AirMax-5 device running AirOS on Ebay for various reasons, albeit I casually still use UBNT AirFiber-24 if I need Gigabit speeds over 24 GHz long range directional links (TP-Link has no 24 GHz device at all).

 

I think it's worth to read the user manual before buying if you want to find out the exact differences (I do so all the time for every device I choose to buy). The manual will reveal whether setup / handling is easy or difficult and how well the user interface has been designed.

It looks like Gen 1 was a SISO and Gen 2 a MIMO 2x2 device, like CPE610 is.

CPE610 can maintain to 300 and LBE-5AC-Gen2 450 mbits/s under best conditions, but the interresting things are, what will this devices do, under not so optimal conditions.

 

Which experience have you made with the receive sensitivity of this devices?

I did not test LBE-5AC, it was not available when I compared the Gen1 AP with CPE510. CPE610 wasn't availabe also back then. My tests therefore were limited to AirMax-5 Gen1 running an older version of AirOS vs. CPE510 running an older version of Pharos. However, things have changed since then, so I really can't tell you what's the better product for your needs.

 

Next opportunity for me to test a long-range link is in 2-3 months (see this story for our test bed in 2017 with Pharos devices), but it's just a distance of 600m and we need more bandwidth than CPEs or LBEs can provide - thus the choice of AirFiber-24 for this particular use case. 

 

It seems you live near me. If you are looking for someone to test long range links, maybe we can set up a test bed; just send me a private message. Kannst auch auf deutsch schreiben per Mail.

Got a WBS210 last week from Amazon.

Attached 2x 5 dbi omni antennas to it, played a bit with tx power settings, channel width, auto channel, but it was always worser (range and speed) than my old wr841nd v10 (openwrt) with the original 2x 5dbi omnis.
 

I have connected my phone and my laptop to it.

Started a continuously ping on the laptop to wbs210 (1 - 2 ms).

Then copied a big file from my samba server to my smartphone.

Ping raised to over 600 ms and sometimes even got timeouts.

 

With wr841nd i'm getting the best throughput on channel 9.

Same channel, same width, same position combo tried with the wbs210.

 

So ordered a replacement for the wbs210 from amazon, which was very quick here.

 

Same results.

 

Later got a nanostation M2 from a friend.

I havent got the timeout as with the wbs210, but again here, much worser than wr841nd.

 

I dont understand the wifi technology at the moment.

They are speaking about AC and so on, but the coverage and range are not getting better.

 

End of the story, sended the 2 wbs210 back to amazon :(
