Re: [WISPA] Problems with Alvarion BreezeAccess VL and Breeznet B100

2008-04-13 Thread John Scrivner
I am copying a friend of mine at a company called Wireless Connections. His
name is Mike Cowan. He is an RF engineer who specializes in Alvarion issues.
He has helped me dramatically improve our VL and B-100 performance. Feel
free to contact him for further assistance. There are many things you can do
to make these system perform flawlessly in these bands.

 perfectly in that area, but we got troughput issues with canopy.

 anyone here had problems like that with the Alvarion gear in a

 in the same area we could manage to work a Airlive Wla5000 (802.11a

Re: [WISPA] OSPF tips

2008-04-13 Thread Eric Rogers
I agree with Bryan, with a tweak.  A trick I just learned with RouterOS
is you put your core routes on the 0.0.0.0 range and add your PPPoE
range to a second area and then do an Area Range in the second range.
It will keep your PPPoE from sending routes to all routers.  It will
summarize them so your routers will get fewer updates.  You won't get
/32 routes everywhere for every user.

Unless yours is a multi-state topology with hundreds of routers, put 
everything into Area 0.  It keeps things really simple.

Re: [WISPA] Problems with Alvarion BreezeAccess VL and Breeznet B100

2008-04-13 Thread Mike Cowan
That's me!

Thanks for the kind words John.

I would 1st run a spectrum analysis to see what the radio thinks it 
hears.  Channel select accordingly.  In a high noise environment go 
the the advanced menu, air interface, noise immunity state control 
and set it to manual.  Give that a shot.

[WISPA] RB532 replacement...

2008-04-13 Thread Mark McElvy
Since RB532s are no longer available, what is everyone using to replace
them? It would be nice not to have to replace the box again (using the
7x6x2's from wisp-router) and I am not quite ready to run v3 on my
network. Any suggestions?

Re: [WISPA] RB532 replacement...

2008-04-13 Thread Scott Reed
I understand you don't want v3, but I have been moving to RB333s with 
3.x and have had no issues at all.  They boot faster and support more 
radios.  RB600 uses same mounting holes and daughter cards.  I have one 
600 ready to install, but have none in production, yet.
I put up a POP with 3 333s on 3RC9 and they are still running on RC12.  
I should get them up to 3.6 or 3.7, but that takes time.  I have a 330 
running 3.3 that is doing great as well.  I have everything from a RB230 
running 2.8.x to 532s running all sorts of 2.9 along with the 330s.
At this point I think you are going to have to bite the bullet and start 
moving to 3.x and the newer cards.

Re: [WISPA] RB532 replacement...

3x is what is out.  The 133 and 133c's are EOL, as are the 532s, 150s 
and for most part the entire 100 series boards.  Figure you will have to 
start using 400s, 300, and 600s.

We do have new cases, nice hinged enclousers and build to spec our 
routerboard series. These will fit the 333's without issues.  We are 
just getting ready to put up a dual-pol n-stream link with 600s, think 2 
foot on one side and 3 foot dish on the other.   

I'm sure we will post the information on our MT list...

You have to replace the board (which means a tower visit) so why not
just replace the PoE at the same time?

Re: [WISPA] RB532 replacement...

2008-04-13 Thread Blair Davis




2 reasons

I've made it a point to make all my tower equipment use the same power
to eliminate the need to keep different spares on hand. At one time I
had lots of different types of power supplies for different things. 

And it is much harder to kill equipment by accident if they all use the
same power.

one last thing... I've never had problems with voltage drop on a 48V
system... no matter if the cable run is 50ft or 300ft. I remember
having to pick the power supply vs the cable length before. This, to
me, is a step backwards.

I no longer replace just the board. I have a standard build of board,
enclosure,static protection and so on... we just undo the u-bolts,
disconnect the LMR and ethernet and swap. We never open the
weatherproof enclosure in the air any more.

Re: [WISPA] RB532 replacement...

2008-04-13 Thread Scott Reed
I agree.  So keep doing that.  Put the DC-DC converter on the units that 
need it and always send 48v up the tower.
Or standardize on the RB600 series.  They go to 56V.

Re: [WISPA] RB532 replacement...

2008-04-13 Thread Travis Johnson




Well, it seems a step backward to install a 24v to 48v converter and
thus add another point of failure, instead of just replacing the PoE.

All of the new boards only support up to 28V, so unless you are going
to continue to find old boards on the used market, at some point you
will have to switch to 24V.

Re: [WISPA] RB532 replacement...

2008-04-13 Thread Dennis Burgess - LinkTechs.net
This is a major issue and all you can do is plan for it.  The stepdown 
from 48 to 24 or 18 is much less of a worry vs AC/DC - DC/AC 
conversion.  The loss should be minimal, and transformers like this, 
should not fail often.  They are simple devices and are relitivly cheap 
and replaceable. 

I do understand, how easy it would be to use all 48 volt.  We even had a 
number of requests for -48v Power Supplies in our PoweRouters.  12 volt 
is easy, the -48 it s a bit harder.  Lots of telco rooms etc use these.

 Since RB532s are no longer available, what is everyone using to replace
 them? It would be nice not to have to replace the box again (using the
 7x6x2's from wisp-router) and I am not quite ready to run v3 on my
 network. Any suggestions?
