Did anybody tested Osbridge 5G AP --- NS5 /CPE?

[bgoksel]

ıf yes;

What is the test results for this setup?

Or;

What you expect as result?

imagine Osbridge 5G with 50 NS5/CPE devices...

I have no experience for this kind of deployment..

Thanks...

[rconaway]

I have experience with both but not together. However, why wouldn't you just use an NS5 as the base station also? You might need 2 of them for that many users if the load is high but it seems to make more sense.

[bgoksel]

BST must be handle at least 50 Cpe with 200 concurrent users..

[rconaway]

I would think about 20-30 you would have problems regardless of the base station. However, you have an interesting question which I may try to investigate. I will let you know.

[bgoksel]

Osbridge guys told that 5G BST devices can handle 256 Cpe for each interface with Polling protocol.For one 5G could handle 512 Cpe concurrent as I understand.

512 Cpe is huge,imagine total connected users to single CPE device!?

[rconaway]

I didn't know about the polling protocol. Does a nanostation support that?

[UBNT-Mike.Ford]

Hey Guys,

OSBridge does indeed have a polling protocol in there firmware.

Thanks,

Mike

[rconaway]

Mike, the polling protocol does't require a response back from the nanostation? It works regardless of the client unit?

[UBNT-Mike.Ford]

Hey Guys,

The NanoStation would need to be running OSWave software for it to work.

Thanks,

Mike

[rconaway]

How do you get the OSBridge software for the nanostation?

[bgoksel]

Osbridge has a similar product like NS5 also.. :idea:

[UBNT-Mike.Ford]

Hello,

You will need to order the product directly from OSWave to have the polling protocols.

Thank you,

Mike

[bgoksel]

Hey Mike,

You mean Osbridge!

[UBNT-Mike.Ford]

Osbridge is running OSwave :)

Thanks,

[tjohnson]

I have a direct email from the main person at OSBridge about their polling protocol. He says "60 clients maximum with 40 online" when using their polling system.

A better question would be if UBNT is going to implement any type of polling system (intelligent, activity based)????

[MaximumISP]

tjohnson exactly the best question :)

Osbridge/Oswave polling protocol and in fact there firmware in general works very well
I am a little pissy with them though as to why they didn't release oswave firmware for the ns units they did for the LS and PS units

They kept the NS firmware version as only being available when purchasing there re badged and re flashed NS5 which they then call a 5si

[tjohnson]

Ummmm... isn't this the guide on how to upgrade the NS5 to OSBridge firmware?

https://www.oswave.com/mediawiki/index.php/Guide_upgrade_NS5

Does this work? I was going to try it tomorrow and see.

[MaximumISP]

Dear lord they did finally release it

Thank You tjohnson I was so pissy about my post in that regard being ignored on their forum
that I haven't been back in a little while
this is very new news ie daurth mauls post for it was only just yesterday
so my info was accurate until then

I hope to see it available for the NS2 soon as well
This is good stuff :) OW polling on my NS5 BH cluster whoo hooo

[tjohnson]

You realize you have to run OSwave on all your clients as well to get the polling feature, right?

[MaximumISP]

Yup I am pretty familiar with oswave

my setup is a bit different than most I am using two NS clusters to BH feed multiple towers so for me the cluster can now run oswave as will the BH units this will allow me to take full advantage of their polling features

I had hoped for this a while ago and it didn't look like it was going to happen by the ow forum so my hope was for UBNT to hurry and create there own polling feature so This is great news to me :)

for the most part I am not using many PTP links this one tower distributes to almost all the other remote towers in a PTMP config

At each pop I have no need for polling not enough subs to worry about it yet

[bgoksel]

Hey MD,

I dont use OW polling protocol and I really dont know really what he s doing?

Could you please describe shortly for me?

Thanks..

[MaximumISP]

Hi bgoksel

By Os Waves definition it is a
High Performance wireless polling protocol running on top of the 802.11 MAC layer which overrides all the shortages of the CSMA/CDMA protocol in outdoor network deployments.

What this means is that APs and client units running on this protocol it can not only increase the amount of clients the AP device can handle from say the existing 30 limit to 60 clients with little or no degradation of client services it also will permit a good user experience even if many simultaneous users are connected

Basically it is a feature where the AP schedules /polls the clients for requests to transmit their data so no one client doing a big transfer or p2p downloads can starve other clients out for air time

Everyone is scheduled by the AP its very Similar in function to Motorola canopy's proprietary polling protocol this is the main reason a moto AP can handle up to 200 clients

Oswave claims there polling mechanism does not require the client radio to issue continual requests to send for their polling mechanism to work which is also a plus

Now since this is an OSWave proprietary feature both the AP and the client will need to run OsWave firmware but for my purposes what it means to me is that I can use my nano cluster as a very effective means of BH feeding other towers without worrying that one tower under load could starve out another BH radio for bandwidth and air time if they happen to be fed from the same nano Ap

Thus I will not require numerous PTP shots for my back haul duties from this tower it will feed 90% of my other towers from the cluster as ptmp

I was previously doing this very thing with a couple moto advantage Aps with sms at the towers and this worked very well so now I can do a similar job at a fraction of the cost :)

[netmaster]

This is good stuff Smile OW polling on my NS5 BH cluster whoo hooo

don't know, but last time I looked, Oswave firmware allowed only polling client, not AP. If you like to use Oswave polling, you must get at first Osbridge 5G or whatever AP from them. Also, NS2 or NS5 probably does not have nearly enough CPU power to do polling at AP side.

[MaximumISP]

Hi Netmaster
I went from woo hoo to boo hoo in < 24 hrs lol

I had a post yesterday at there forum asking for clarification on that very question
What I did find on the website is this statement "client mode to OSBRiDGE 5G when operating on 5 GHz, Polling Access Point/Client modes when operating on 2.4GHz "
So it appears that you are correct on the 5G but supposedly it can operate as a polling base on Oswave but only in 2.4ghz

Which is still ok for my purposes if need be I could replace the NS5 cluster with a couple of 5g sectored units but for now I will just leave it ..so far it is performing quite well anyways

None of these remote sites have big demands for bandwidth 3-7 meg per tower is lots right now and so far no single NS ap on the cluster has more than 5 links and may not ever require more than that
so I don't feel the processor power required for those few devices is of grave concern just yet at least not for me
Many clients connected simultaneously to a NS AP is not my goal for polling smoothing operation to few slightly higher capacity ones is

That may not apply to someone else with a different configuration or hoping to have many clients connected to a single NS ap viewing polling as some magic bullet

tjohnsons previous post "I have a direct email from the main person at OSBridge about their polling protocol. He says "60 clients maximum with 40 online" when using their polling system. "

I don't think that applies to their 5G product as I would guess it could handle more than that given its extra horse power (Intel XScale IXP425 533MHz) with dual radio interfaces combined with their polling protocol I would expect to see 120 clients connect able to that device only judging by the quoted statement of 60 Max

Therefore I am assuming that his post is referring specifically to a NS2 running as a polling base ( but perhaps he can clarify this with Leszek )

I will follow up if/when I get a reply

[netmaster]

I don't think that applies to their 5G product as I would guess it could handle more than that given its extra horse power (Intel XScale IXP425 533MHz) with dual radio interfaces combined with their polling protocol I would expect to see 120 clients connect able to that device only judging by the quoted statement of 60 Max

don't be so sure. I have some 5G's with total of ~35 clients connected, and CPU usage shows 70% (via SNMP) peaking to 100% sometime. 120 clients is way too many ... 60 - maybe....

[rconaway]

Except for a large client deployment environment, which operating system works the best. For example, which one works best in PTP? Does OSWave use less overhead so that throughput is higher with the 40MHz channel? Has anyone tested that?

[MaximumISP]

Here is the reply from OsWave

NS2 supports both polling base and polling client modes (generally when operating in 2.4GHz both modes are supported).

In 5 GHz mode (ie. NS5) only polling client mode is supported due to hardware processing power limitations.

I am not sure why they state that the NS5 polling base is not supported due to hardware limitations since the NS2 and NS5 have the same processor specs does 5ghz put more overhead on the processor in some fashion

Netmaster from what your saying it would seem to me that the Xscale board can thus only handle 30 clients per interface max so it almost seems that the polling is of little or no benefit
At least as far as allowing more clients to be served from a single Ap
Since that board should be able to handle the 30 clients per interface even without polling ..are you actually using their polling if so do you find it of much difference with or without

rconaway no idea but Id also like to know the answer to that

[rconaway]

Max, I agree. It sounds like polling is sort of irrelevant if you are processor limited anyway. Similiar to the turbo mode issue.

[mrapo]

You guys obviously never used polling capable system on an AP with 30 active subs running p2p filesharing, where polling or non polling is like good customer experience vs 'is this what you call internet access?' customer service calls.

On osbridge base station with polling enabled processor utilization is +-70% no matter if you have one subscriber connected or 40 subscribers connected, therefore I assume processor power utilization is irrelevant there.

[rconaway]

You are right. I have never used it. Thank you for the feedback. My biggest network has 30-40 users on a single AP at 2.4GHz. I'm using Vivato AP's for the base stations. However, my load is not that high since these people are infrequent users.

So here is my question, is the OSWave firmware available for free or is there a licensing fee?

[mrapo]

Well, that depends. You can buy the licenses online at oswave.com for a fee, or I have been told there's a 'free' version available on emule. And these emule people also have 'free' versions of Mikrotik too.

But hey, what do I know.

[rconaway]

The firmware is on www.osbridge.com. I don't know the licensing issues but the directions to upgrade your firmware is in this thread. $24.95 per device is kind of high for my applications. I might download it and test it on 2 devices to see what happens. If there is a performance difference, I'll take a harder look at it.

[netmaster]

are you actually using their polling if so do you find it of much difference with or without

Yes, all my 5G's use polling. Bigger difference is in city area, where polling helps a lot. In country area, where customers "density" is lower, there is no big difference. Is very complicated to do a exact test, because all clients must be reconfigured every time.

Because of poor quality, and more poor support, we trying to abandon 5G's together their proprietary polling. Instead, we make more cheaper AP's with less clients connected to them without polling. Lack of choice for AP hardware/firmware is main downside for polling so far.

I am still pissed off, because another 5G on 45m tower died today, like always, in friday evening, just before weekend.

On osbridge base station with polling enabled processor utilization is +-70% no matter if you have one subscriber connected or 40 subscribers connected, therefore I assume processor power utilization is irrelevant there.

Maybe CPU is not used proportionally more, when client number rises, but there is correlation. I have many 5G's (19pcs), and after short sweep, may say, that with
2 clients - less than 10% CPU
6 clients - 30%
11 clients - 50%
30 clients - 70%
largest client number we have, is 35. CPU graph is still ~70-75%, but web interface feels much slower than with 11 clients.

This is what I found on one of the russian online forums:

OSWave 2_21R Keygen by TeAm ViRiLiTy

http://www.driveway.com/t7x6v5e0w8

[rconaway]

Netmaster, when you say died, did you mean completely failed. I"m using a pair of 5GXi and they have been running for about 4 months without issue. However, we are using watchdog in case they lock up. In addition, I have a matching pair sitting in a box for this problem also since I'm running an entire city backbone on them. I have more problems with my Solectek's than I do this one. The 900MHz OsBridge units however, were a bigger problem. Had a lot of problems with those initially. Been pretty good since then.

[netmaster]

Netmaster, when you say died, did you mean completely failed.

no, the last one (and many before) died, like in picture below. This is signal graph from one 5GXi working as client for that 5G.

http://www.ktg.edu.ee/temp/sig.png

power and/or sensitivity is lost and thats all. At this case, power was lost, because it still can see another distant 5G's with normal signal level with site survey. This shows also, that antenna and cable is ok. Some have starting restart itself like mad, some just hang periodically, some does not recognize any miniPCi cards anymore. Various things. Like I said, we have 19 working 5G AP's and 6 of them is failed at no reason and got replaced. Maybe this is just bad luck. From time to time, I gather them all together and try to build some working devices from several dead ones.

[mrapo]

If you have miniPCI cards in these APs breaking like that then you have most likely not grounded antenna installation or use antennas with crappy VSWR.

What kind of antennas you use on these osbridge aps?

[rconaway]

There are three things that I can see causing your issues. The first have already been mentioned, SWR and grounding. The third is line voltage. If you are using built in antennas, SWR is eliminated (that is unless it's a crappy design), grounding is effectively eliminated (unless you are losing network interface ports in which case you need to ground the CAT-5 line right at the radio), or possibly line voltage. If it's line voltage, get a cheap surge protector on there. You are probably going to have to set up 10 of your locations with this setup for a sample and see how they last compared to the ones without it. If it's an external antenna, add in a coaxial surge protector also.

[netmaster]

If you have miniPCI cards in these APs breaking like that then you have most likely not grounded antenna installation

no, all antennas and device itself is grounded.

or use antennas with crappy VSWR.

even so, then this is rather crappy miniPCI cards. Not any VSWR cant kill 30mW card. The system was working before, and clients was connected, so VSWR can not be that bad. Same type of cards (WLM54 something) have many times burned out also in devices with builtin antennas (5GXi and 5XLi).

You are probably going to have to set up 10 of your locations with this setup for a sample and see how they last compared to the ones without it.

Most of the places is migrated from another 5Ghz radios. Mostly from Proxim MP11a's, and I never have seen a single failed miniPCI radio before, with same antennas and same grounding and installation methods.

[rconaway]

I will be the first to admit that I wasn't all that impressed on the quality of the OSBRidge stuff. We also bought a lot of the highgainantennas 2.4GHz radios and their failure rate is also kind of high.

[MaximumISP]

Hi guys
I have always been fairly pleased with the Osbridge /OsWave firmware till today that is
rconaway I also went through hell on the old HGA 8186 radios

-==Warning do not try to load OsWave firmware on your NS2s just yet ==-
I have bricked two now trying to return them to AirOs
WLAN was non functional under OsWave firmware

Ns5 OsWave firmware swap went fine even when starting with AirOs 3.2rc
they recommend 3.0 as starting firmware prior to upgrading

So much for my polling feature hopes :( #$%&

[netmaster]

Ns5 OsWave firmware swap went fine even when starting with AirOs 3.2rc

was NS5 working with Oswave? What was wrong with NS2 WLAN?

[mrapo]

I will be the first to admit that I wasn't all that impressed on the quality of the OSBRidge stuff. We also bought a lot of the highgainantennas 2.4GHz radios and their failure rate is also kind of high.

I am happy to say that my experience with osbridge gear has been very good so far then.

How's highgainantennas 2.4GHz radios related to this topic anyway?

[MaximumISP]

netmaster

Yes Ns5 seems to be working fine at least one of them seems to be
the second one I did spits out a UNKNOWN ERROR when using the site survey tool
other than that it appears functional lol!

I am going to try to downgrade it and reload again and see if that clears it up
It could be that I made a mistake and the first unit was not running vs 3.2RC2
don't think so but its possible I would recommend you use AirOs 3.0
as the starting firmware like they suggest if you were try to load it on an NS5

My post at the OsWave bug ward describes it a little bit more http://www.oswave.com/forum.html/viewtopic.php?t=289&sid=01232b8a36ef5629b4a75824d10ceebf

I have definitely bricked the two NS2s
reset don't work and shows no LAN connection at all now
This blows chunks... it wouldn't bother me so much if the NS2s weren't so damn hard to find right now

Just though I would warn others about my foolishness

[rconaway]

I was scheduling this for Tuesday with one of my techs. Obviously I'm definitely waiting. I have 2 NS5' in stock but I'm thinking that sacrificing them is not the best idea yet.

[rconaway]

BTW Max, it isn't foolishness. You just beat me to it. I appreciate your efforts. If I get any more NS5's in stock, you are welcome to them.

[WHT]

if the NS2s weren't so damn hard to find right nowWasn't the next production run supposed to have been rolled out one or two months ago?

[MaximumISP]

WHT so Ive heard lol
I believe that that particular run..... ran away

rconaway thanks kind of you to offer
I have 30 or so NS5s left so I'm good its the NS2s I have only a few of

New update I was able to get that Flakey NS5 back to AirOs 2.2.1
Then I flashed back to oswave again with similar results using site survey tool
shows this on a blank page but only after quite a long awhile

eth1 no private ioctls. eth1 no private ioctls. eth1 no private ioctls.

also clicking on the interfaces menu item
produces either a page not found or a blank page
what any of that means I have no idea
So I flashed it back to airos and its fine again so it would seem
that no NS5s were harmed during this experiment

I am wondering if there is some difference made in the file structure
the one NS5 that flashed and functions perfectly may have been an older NS5
I am about to rip open a brand new NS5 and try it again lol

I'm also tempted to try a brand new NS2 but I only have two left and
I don't really wanna sacrifice any more in the name of science

I am wondering if it might have been ok on the NS2 as long
as the NS2 had 2.2.1 on it already and was never updated to 3.0 or beyond first
I do recall a similar problem I discovered loading OsWave on the PS2s which I posted about here http://www.forum.ubnt.com/forum/viewtopic.php?t=759&highlight=

and at OsWave forum http://www.oswave.com/forum.html/viewtopic.php?t=241&sid=0f438579bedd30397b6a6ee003c5c8b9
this was back in March bringing the issue to their attention
..me thinks I may have stumbled into something along that line again

Out of the two I toasted one was definitely v3.2Rc2 the second
I am not sure if I had to downgrade it to 2.2.1 from 3+ or
if it was already running 2.2.1 I have flashed so much today I forget lol

[rconaway]

Those runs are gone. We got a few of them but even the distributors are having trouble keeping them in stock. I just sold 4 Powerstations and both my distributors are out of stock on those also. My concern is that I'm about to deploy 2-3 cities over the next 6 months and I'm going to need a few hundred. I'm hoping that supply stabilizes by then. I'm having to get my Powerstations off Ebay and I'm paying more than retail.

[WHT]

My concern is that I'm about to deploy 2-3 cities over the next 6 months and I'm going to need a few hundred. I'm hoping that supply stabilizes by then.

We're looking at a several hundred subscriber unit deployment over the next six months. I figure it will be less expensive going with another manufacture compared to starting with UBNT and discover half way across the river we need to switch horses and attempt to maintain a deployment with two different radios.

An oil well servicing company has a two hundred unit deployment in mind and was asking me about the NS2. I recommended another product with a better track record of supply.

The newest shortage of the last production run is clearly the point where UNBT "jumped the shark".
http://en.wikipedia.org/wiki/Jumping_the_shark

[rconaway]

We have been supplementing our supply with products from highgainantennas since we started with them. However, the lack of quality and the price difference from highgainantennas 8186 had us switch. Unfortunately the lack of product availability is becoming an issue. The project I just did where I spec'ed in the PowerStations in for city government employees and backup for two 1GB PTP links is over $60K and I don't have the luxury of changing products once a P.O. is issued. I had to find the radios on Internet and paid over retail to keep this project on schedule. Even then I'm putting up my last 2 NS5's on the links where I don't need a lift to replace them later when I finally get to order the last 2 PowerStations.

[bgoksel]

Finally,Oswave decided to support Ns2 :)

http://www.oswave.com/mediawiki/index.php/Guide_upgrade_NS2

[physical]

now if only they would decide to be GPL compliant and release source code for the GPL code they use

[encom]

hello, lotof you are using NS5 with 5G both on OSbridge. what is the top speed possible to provide for clients in this configuration ? iam thinking about 8megs per client - but its not possible without polling.

[rconaway]

Until somebody does an actual test of oswave, I don't see the benefit in a scenario where there is bandwidth throttling on the Gateway. For example, we use FirstSpot as our gateway and we allow 1Mbps download and 256K upload. That means that nobody is capable of swamping an AP since they will be throttled by FirstSpot anyway. If we still have that problem, we can reduce bandwdith on any individual user. We also get a counter as to how much bandwdith a user is using. I would stay stick with AirOS unless somebody provides some actual proof of better performance.

[mrapo]

You obviously have little experience with customers using p2p clients or udp protocol based applications. Once they hit your FirstSpot traffic shaper they will already bring your AP to the knees, and not because of generating more than 256kbps on the uplink, but becuse of generating 1000 64 bytes packets per seconds.

[MaximumISP]

I agree with you mrapo

What I have seen is Its the mind boggling amount of simultanuious connections that causes the problem not the actual data moving

Connection limits and a polling protocol are the only two
things I want to see in AirOs right now
That will solve alot of problems for me

[rconaway]

Mrapo, I have quite a bit of experience with both having managed some pretty large public WiFi deployments. I will agree with what you say except I left out a few things. For example, we don't see a lot of UDP traffic at our sites or PTP so I don't typically have that problem. However, we do monitor total traffic and when it starts moving up, we may throttle the port address causing the problem at the switch, completly block it. or take that MAC address off line completely. I just installed my first Nano's as AP about 2 months ago although I have a lot of them installed as clients.

If we see an AP start to slow down in response time, we isolate the issue or user and take action. Sometimes that means they get knocked off completely. Our EULA for the client gives us the power to pretty much do what we want if we start to see issues. A bigger problem for us has been viruses or trojans with spamming.

I'm not sold on polling at this price point. I will say that I might look at different AP's if I run into that problem but I understand what you are saying. If I'm going to have that problem, I'm probably going to handle it by taking that user offline and I'll know it in 30 seconds.

[MaximumISP]

rconaway yes I think that what you left out is that you definately do have a method of dealing with a problem client and an effective means of monitoring it for problems in order to respond quickly
its not the do nothing plan lol

I shape pretty well from the gateway myself but I have had a couple instances where a client was able to crash the tower with over 1000 simultanious connections as my current pfsense gateway box has no connection limiting means having con limits or packet per second limits would have solved it right at the client before it ever got to the AP

Esentially the clients plugged most of the dynamic ports which made it difficult for me to access the ap remotely to even shut the offending client off ...which just sucked

To have a easy way to prevent that from happening ever again without me having to watch it 24/7 would be great
connection limits has really been the most effective cheapie means I have found
a netequalizer box would be nice but is outta my reach right now

I can say from my own experiance that polling does work very well on high load APs and offers tremendious benifits ping times increase a little bit but the over all user experiance for everyone smooths out nicely

I have yet to see a more effective method for dealing with the hidden node issue and both these features can be software implimentations so there should be no cost increase per say I sure dont want to see a price jump to have them thats for sure

Hi crespopc I tried to warn others in my previous posts regarding the ones I bricked
but thanks for confirming it isnt just me :)

That said Lezeck from Oswave has confimed a firmware flaw
with the NS2s at least with the lack of antenna selection to me via email
he said it would be corrected with in a couple days but I havent heard back yet
and its been a week or so now yet the firmware version on the website still shows same revision #

He doesnt believe there are any other flaws with the firmware or that going back to AirOs
causes any problems but I sure do and screw what darth maul said we know different

I would also like to get details on how to use the jtag as a recovery method
and mayby I can salavge some of these Ns martyrs

[nickalot]

Regarding pier to pier.

Really dislike it.

Connection limiting is fair to all. If a client has an aggressive p2p application, his browsing experience will be terrible. All other clients will cruise along happily. You can also achieve similar results using simple storm thresholds (30).

The polling systems, if they work like Karlnet, are also annoying. In my experience, the hidden node issue is almost mythical. You will really only notice it if there is substantial interference in the area. RTS (256) and 802.11b will overcome the interference (and hidden node issues) as long as you can maintain c/n of 7dB minimum. Identify the problem client(s) by using a simple program that pings all clients every second. Check nonags.com or buy pingplotter.

In the long run, polling for a large number of clients will amount to a headache. It will, however, keep any wifi compliant radios off your Network. If it is a real issue, I would go for a proprietary system.

[rconaway]

I just read their website. Their tech support still really sucks and too many people are still having problems. They could have the best firmware on the planet and it wouldn't be worth squat yet. Nobody could deploy this and expect to get help if they found a bug.
