Re: [WISPA] UBNT APs: can they do UAM + DHCP on one fat AP?

2012-07-06 Thread Rogelio
Thanks, Sam.  That is helpful.

FWIW, I'm currently researching the following things on UBNT...

1) How exactly is UAM done on all Ubiquiti radios?  Specifically, can
an AP do the following...

a) white lists an offsite portal page (e.g. NNU or Aptilo)
b) redirects unauthorized users to this portal page?
c) after client pays on portal page, tell the AP UAM webserver on
Ubiquiti radio to authenticate the user
d) pre-authenticate user MAC addresses that roam from other APs?

2) If a Ubiquiti device already services an SSID, how can it also
serve a separate SSID that (a) does it's own UAM, and (b) does its own
DHCP scope?  Can I do this existing hardware?  Or do I need to get a
new radio for each new service?

Ideally, I'd like to stack services on existing UBNT networks, as
well as roll out new ones...hence the reason I'm hoping for some sort
of simple UAM overlay.

 This sounds pretty much like UniFi.  The UniFi units do not handle the DHCP
 so you would need something handing out leases like a small Mikrotik box.
 You then add all the UniFi units that you want to be 'seamless' to the same
 network in the unifi controller.  The unifi controller can be run anywhere
 that is reachable from the UniFi units (the UniFi's do not have to be
 reachable from the controller though, so then can be behind a NAT).

 In a past life, I've often just put in an access point with some sort of
 DHCP solution and UAM redirect. This AP plugged directly into the modem
 (DSL, cable, etc) and then got a public CPE address which I could manage
 remotely. When customers hit the open SSID, they got a spash page that was
 served by NetNearU (NetNearU.com), and when they authenticated, their MAC
 was whitelisted on for the duration of time. When they went to another AP
 that had a different DHCP server, their MAC address was pre-authenticated
 and they appeared (from their perspective to roam).

 A few questions on how I can do this The Ubiquiti Way.

 1) Does Ubiquiti do DHCP at the edge on each AP? If not, is there some 3rd
 party software I can use? I understand if this is not supported and if I
 have to figure this out myself. That is not a problem.

 2) Does Ubiquiti have a way of vectoring the users off to this database? I
 see that Chili has a plugin, and it looks relatively simple to integrate.
 Does this still work with the current OS? Or have things changed?

 3) Can someone recommend a hosted user database solution that is cheap and

 4) Do I have to use UniFi? Can I just script out some sort of login script
 to quickly deploy and configure these thigns?

 This project (if it takes off) could be about 1000-2000 thousand APs
 scattered across rural Africa and South America. I'm hoping for limited
 equipment at the edge (things like battery backups and customized antennas
 may be needed in some cases, but I'm hoping for limited network equipment).

 If anyone has any ideas or would like for me to connect them with the
 various decision makers, please feel free to contact me offline. I'm not

[WISPA] carrier grade label on WiFi products

Every vendor now uses the term carrier grade WiFi, and I'm curious

To me, it's something like...

high level
--features that help increase ARPU
--features that let it be operationalized easily

lower level

--ruggedized
--interface to existing provisioning systems
--easily maintainable

Future things will include (I think)

--ability to interface with 3G/4G systems for offload (EAP-SIM, EAP-AKA)
--seamless roaming in and out of different RAN zones

[WISPA] just installed a Huawei...

2011-07-25 Thread Rogelio
Not sure if it's any interest of this group, but I just installed a
Huawei CX600 router this last week.

It's like Cisco quality (garbage!) for the price that Cisco should be
(low!).  The commands are very similar (e.g. switchport - portswitch,
no shut - undo shut, etc), and you configure it almost identical to
what you'd expect on a Cisco.

The worst part about the Huawei is probably the documentation.  It's
scattered all over the place, so if you want something simple (like
telnet access), it's in a completely different PDF than if you want,
say, VLAN configuration commands.  Finding it all is a huge scavenger
hunt.

But hey...for like a 1/4 of the price or whatever (so I've heard), I'd
say it's worth it.  :b

[WISPA] band pass filters

2011-03-14 Thread Rogelio
For what it's worth, I had a super noisy Wi-Fi noise environment
(hundreds of clients, dozens of APs, little to no channel
coordination, etc) and got a handle on the situation by putting these
band pass filters

http://www.rflinx.com/products/filters/2400/bpf/

I got several of each, but I ended up using channel 1 mostly.  When I
put that puppy in, I got like 40 dB less noise on the channels I
didn't want, and I also could not even hear other APs when I moved the
radio to channels 2-11 (there is that much isolation in the filter).

Now throughput is much smoother and higher.  Before I put these in,
bandwidth would be slow and come in spurts (as evidenced by various
throughput tools like iperf and online speed tests).

(2) What exactly does it do to other APs to make associating to them

associate?)

[WISPA] where is Meraki a good fit?

2010-12-01 Thread Rogelio
A friend of mine has Meraki through a provider here in CA, and I'm 
curious what others think about them and their niche (particularly those 
who have found a great niche).

Personally, I don't see a solution like this taking off unless there is 
the right demographic (poorer areas, underserved areas, certain 
campuses, etc).  In main areas covered by 3G and affordable cable / DSL 
(e.g. $15/mo DSL Extreme), there seems to be little reason to really 
build out something like Meraki.

I could see it in, say, an apartment complex, particularly ones where 
people are moving in and out and just want temporary access.  In these 
cases, there is a way for the complex to at least pay for part of a 
wireless solution for their tenants.

Another issue I see with Meraki is that for billing, it has to be an 
open SSID.  What about problems such as Firesheep?

http://en.wikipedia.org/wiki/Firesheep

Sure, the credit card info is encrypted, but once someone attaches to 
the AP, then all of their traffic is clear text.  I don't see anything 
in Meraki (at least the GUI I saw tonight) that prevents this sort of thing.

[WISPA] affordable outdoor/indoor CPE devices

2010-11-30 Thread Rogelio
I've got a situation in several non-US countries where various 
restaurants would like to hop on to a public network.

In these cases, the public network covers, say, 50% of an outdoor area

In these situations I'm looking for a CPE device (Ubiquiti?) that might 
receive the signal (5-10 dBi gain?) then run the signal down an ethernet 
cable and retransmit that SSID down below.

Any suggestions on ones that might do this for cheap?  Cheap is key here.

and re-transmit the signal?  (Sorry, haven't tried this yet)

Or does the originating AP radio have to support WDS also?

[WISPA] chipset vs standard based beam forming?

2010-10-25 Thread Rogelio
I see lots of discussion about the new 802.11n standard supporting
beam forming, and I'm trying to wade through the chipset ones (e.g.
Ruckus, Extricom, Meru, etc) and other solutions that claim to be more
standards based.

From what I gather from the marketing literature, the various vendor
solutions direct the signal more efficiently towards specific
targets (focusing beam in certain direction, monitoring interference,
interference nulling, etc), but that seems to have limited
effectiveness when it comes to receiving transmitted packets from the
client end (resulting in slow uplink?).  In some of these cases, the
receive antennas are just an omni antenna. (802.11 is not a timing
based protocol, so I don't see how beamforming benefits on the receive
side will ever happen)

So is the best that we can hope for with beam forming is faster
download but the same old upload?  How will the standard (once baked
in more vendor gear) do things differently?

[WISPA] expected goodput of Motorola's WiMAX 3.5 GHz access radios?

2010-09-30 Thread Rogelio
I am working with someone who inherited a ton of towers with Motorola
WiMAX 3.5 GHz access radios on them.

They want to get a bridge on the other end and then connect a Wi-Fi
server on the other end (connected through an Ethernet cable).
Assuming perfect receive RSSI and modulation, what is the upload /
download speeds that I can expect this transport to support?

[WISPA] Recommendation on Redline's PtP line?

I've got a project where I need some affordable PtP links with as

They are TDD, and from what I hear, they are conservative in their
throughput numbers but tend to outperform other vendors who inflate
their numbers.

Any input there?  The ones I listed there run about $1600 retail on
TESSCO's site.

Right now, I've been looking at Hitachi, EMC, and Compellent (all
fairly expensive). I also started looking at Dell's Equallogic line

things about include Pillar but haven't looked at their pricing yet.

those signals are combined automagically (in theory, of course).

So, yes...Ruckus has the reputation of making some kickass antennas to

that edge now that the standard is solidified by IEEE.  Put
differently, how smart are their antennas now that the standard does
a lot of what they were bragging about before?  Is their secret

 May be 802.16m can achieve 4G goals, if WiMAX still lives by then.

LTE-advanced may approach ITU's 4G standards, as 802.16m (WiMAX 2) might also...

Some call LTE 3.9G (or something weird) because it's way beyond 3G,
but technically falls short of the ITU's official standards.  The
final goals of LTE-advanced, as I understand, will exceed 4G
requirements.   (But no telling when that will be, of course.)

As for 802.16m (WIMAX 2), it will have its place, particularly in
surveillance and grid networks.  A lot of countries are auctioning off
2.3 and 2.5 GHz, and many companies are buying these frequencies with
WiMAX solutions, but for the most part I've seen 90+% of carriers
(e.g. ATT) betting big on LTE.

There is some speculation that later this year, WiMAX 2 will be at a
better (faster, etc) place than LTE at the same time.  WiMAX
supporters say that WiMAX is more open (and thus better in the
long haul), but as we see in the Linux vs BSD arguments, open comes
with a set of problems that more structured solutions don't always
have (and vice versa).

Others thoughts?

[WISPA] 2.4/5.x GHz load balancing

2010-03-31 Thread Rogelio
As more and more devices support 5.x GHz access, is there solutions to
auto optimize clients on the best 2.4 GHz or 5.x GHz channel?

That is to say, 2.4 GHz goes farther, but 5.x GHz has more capacity
and is less cluttered.  Say a new iPad sees both signals, is there
an access point that could figure out the best band for it (receive
signal for STA, best SNR, etc) and then somehow strongly suggest
that the STA switch to that band?

[WISPA] power management tools for cell sites

2009-12-24 Thread Rogelio
I'm hoping someone on this list might recommend me some power
management options for cell sites.

Ideally, I would like something that does the following:

--auto-reboots a device when an IP address does not ping
--is ruggedized for outdoor environments (or is easy to stuff in a NEMA 4X box)
--let's me http or ssh in and reboot certain ports
--is affordable enough where I could just budget it in with all of the
cameras and wireless devices

Tools like iBoot are a step in the right direction, but it doesn't
seem to have very many features, and I will likely want some SNMP
features so I could, say, graph the power levels in Cacti .

(The idea here is to be able to proactively troubleshoot stuff to
avoid a truck roll, and if I do have to do a truck roll, I know that
the most obvious power-related stuff has been done first)

with a PtP link that was like 7 miles.

If each end is encrypted with an AES key (along with a ton of other stuff,

Does PCI need something additional?  I figured that lots of other stuff goes
into PCI compliance, and that this was a small thing compared to the whole

[WISPA] NCIC, FIPS, and wireless

I'm planning out a wireless network, and the police want a piece of the

I'm also guessing that FIPS compliancy addresses NCIC concerns, and I

I'm also wondering if a dual form of authentication adequately addresses 
the security issues. From what I can tell, if the police do any of the 
following things (listed in the URL below), then they have to follow NCIC

A contact of mine who works for the police tells me the following 
interesting things about NCIC, which I'd love feedback on...

--if you use PtP links (e.g. T1 lines) between sites, requirements are 
very lax
--if you don't use PtP links, then you'll likely need two form 
authentication (not necessarily two on separate bands)
--everyone assumes that a police network *will* be in compliance
--people often build police networks with compliance, as someone will 
inevitably put secure stuff on top of it later
--the penalty for not being compliant is getting shut down until 
everything is reviewed
--only police departments can ask the DOJ for clarification on what is 
and isn't compliant (vendors can't ask directly)

Not having a lot of high capacity PtP experience, I only really worked

For what it's worth, I talked to a buddy today who does quite a bit of

He had some questions on the types of radios that I'd be sending these 
LACP 802.3ad packets through (to make sure that they passed them through 
to the switch on the other side), but he said that if all of that was 
kosher, then he'd just stick with LACP features and avoid adding STP to 
complicate things.

He also recommended using the *dynamic* LACP features, rather than 
static features, as the static features were really designed for legacy 
devices and did primitive load balancing like round robin (which could 
cause problems in the lower modulation scenario that you gave).

Thanks for your feedback. If people are interested, I'll post the 
solution that I find works best for me.

[WISPA] LACP + Wi-Fi = ghettofabulous big wireless pipes?

2009-06-12 Thread Rogelio
I've got several outdoor Wi-Fi radios that I would like to configure in 
a PtP configuration on multiple 802.11a channels.

My question to the list is, Can I use LACP on each end (via a network 
switch) to aggregate those PtP connections into one virtual connection?

e.g.

http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a0080094470.shtml

So, instead of using ethernet to each switch, I'm connecting an ethernet 
cable from my switch into the 100 Mbps LIM of the radio node, creating a 
PtP link across an area, then coming out that other radio's 100 Mbps LIM 
via ethernet into another LACP-friendly switch.

So, on each port, there is something like...

switch-ethernet-radio- 5 GHz PtP link-radio-ethernet-switch

Any feedback on this?

we're doing

http://www.dhs.gov/xprevprot/programs/gc_1185556876884.shtm

I'm curious if anyone else here has had to do this for any wireless 
opportunity.

(It's an easy thing to qualify for.  Just read through the training 
[about 30 page clicks], answer like 7 questions, put in your contact 
info, and you get an email with your CVI number.)

On a side note, what other certs / clearances / passes are relevant in 
the federal space?  I'm relatively new to working with the government, 
and am surprised at these various obstacles, which others seem to take 
for granted. :b

[WISPA] document version control? (e.g. web-based solution to check out KMZ files)

2009-06-05 Thread Rogelio
I've got a question that tangentially pertains to wireless stuff, but 
isn't really related to wireless technology, per se.

We sometimes have several people working on KMZ files, and the different 
versions that we have gets really out of hand, and I'm hoping for a 
web-based (LAMP?) solution that lets people sort of check out a KMZ 
file and then incorporate some sort of version control.

(This isn't really unique to KMZ files, of course, but could be for any 
sort of file. It's just that KMZ craziness is killing me more than, say, 
Word doc or xls craziness.)

Any nudge in the right direction would be greatly appreciated!

This is a good question, as I have not had to worry about 900 MHz until 
really recently when I started worrying about integrating with Shotspotter.

I know little about the characteristics of the 900 MHz band, but perhaps 
it's an issue of demand?  Based on my experience, this band is used 
mostly in the public safety sector, so maybe they charge just because 
they can sorta thing.

Anyone else have anything to add here?

A lot depends on the company that originally made the hardware.

In some cases, Cisco bought a great hardware manufacturer, in which case

Is there anything that anyone has to add about either one of these

Re: [WISPA] marine interference problem on 2.4 GHz

2009-05-24 Thread Rogelio
Jack Unger wrote:
 I respectfully suggest you hire an expert to address this problem.

In light of Jack's comment, I thought I'd share with everyone my 
non-expert opinion on what the ultimate problem is/was (I was out 
there last week):

--poorly placed radios,
--poorly placed antennas, and
--some mysterious boat radar

Without the s-band interference and the boats, there are definitely some 
cold spots, but the bands have relatively little interference the vast 
majority of the time. A radio higher up hits most of the dock, and a 
radio really high up in certain certain areas gives all boats in the 
area a fairly okay LOS. (hrping tests at 100ms gave me less than 5% 
packet loss at like -65 - -70 dBm when the radio was about 1000' feet 
away high up). Also, you can try to hit the boats from multiple angles, 
giving the boats a higher chance of having one or more SSIDs to hit when 
one is blocked.

These boats pay anywhere from $6-8/foot, which can amount to $1000-2000 
per night.  They expect Internet access (many of the boat owners own 
companies like Monster, Y!, Google, etc) and aren't too forgiving. There 
have been a few foreign boats that come in and basically excrete on the 
2.4 GHz band for everyone.  No one knows who it is until the big boat 
leaves, then all the problems magically go away!

Anyway, hope this helps others on the list.  I got bad/stupid/incomplete 
information earlier, hence the general n00b-ish feel to my earlier post. :b

If anyone here knows about building stuff on docks in marine 
environments, I'd love to talk to you and can probably refer you some 
big clients.  (I'll perhaps post that in a different thread)

[WISPA] suggestions on lower end PC appliances?

2009-05-13 Thread Rogelio
I'm looking for some sort of small *nix friendly appliance that I can 
put at the edge of certain wireless mesh networks.

That way, I can integrate some open source monitoring tools there and 
test bandwidth / connectivity.  Nothing fancy, just maybe the likes of 
iperf or Nagios ncsa that can give me some sort of extra visibility at 
the edge.

I've heard good things about the Soekris boards, particularly from guys 
in the BSD community. The problem is time and finances.  I'm not sure 
that this is the best sort of solution, given those constraints.  But 
it's one option.

Another option is just using Cacti's ping latency tool. In the past, 
I've found that latency is a so-so way of telling how full a given 
pipe is (not perfect, but better than nothing).  I could also, I 
suppose, configure Cacti to poll each node to give me a reading, but 
that is likely too detailed (but maybe necessary for certain nodes that 
prove to be difficult).

If I had a place to rack a box remotely at these various sites, then I 
could use a lower end PC. Unfortunately, however, I'm likely going to 
limited to some sort of enclosure, hence the reason I'm looking at lower 
end appliances.

[WISPA] marine interference problem on 2.4 GHz

2009-05-01 Thread Rogelio
I've got an interesting interference problem in a marine area, and I was 
hoping to get some feedback on it.

Every week or so, something evil on 2.4 GHz comes through and 
drastically raises the noise floor for about a day (an analysis showed 
me like -50 dBm), thus knocking off everyone in the boat dock area who 
is using that AP.

I was thinking about the following type of solution and wanted to get 
some feedback:

--on each dock (9 total), have two dual radios
--mesh them on an available 5.8 GHz channel (this band is not currently 
a problem)
--put in a 2.4 GHz panel antenna on each end (maybe a 19 dBi one that 
gives, say, a 30 degree X 30 degree beam coverage). 7 dBm + 19 dBi = 36 
dBm EIRP for ISM band in U.S.
--have panels on each radio pointing in towards the middle dock area 
(boats in the middle would have redundant coverage.  Boats on the far 
edge would likely only be covered by the distant AP)
--cover each dock with two channels, so if one channel is down, another 
one is an option (or possibly the same channel on a different polarization)
--possibly use band filters (assuming I know which band is the problem 
child)

Any help would be greatly appreciated.  I'm quite new to figuring out RF 
problems like this.

If I remember right, they had redundant fiber there already.  I also 
remember something about the person doing it knowing that and cutting 
both sides of the ring.

Agreed, though -- secondary wireless connections would be a good backup 
in these sorts of situations, particularly when temperaments of union 
members have been high.

I was actually in Cupertino when it happened (on Apple's campus), and I 
noticed a blip in my iPhone's data services at that time.  I never knew 
what it was until I said something to my friend at Apple, and he had 
just heard the news.

Re: [WISPA] Time Warner Tests $150-Per-Month Unlimited Internet

2009-04-12 Thread Rogelio
On a somewhat related note, does anyone here use open source packet 
shaping solutions?

I've only used Packeteer in production (enterprise environment), but I'm 
always on the lookout for good other solutions.

Right now, I'm using BSD-based pfSense at home, and that seems to be 
working great.  Others I know are just using OpenBSD proper and just 
putting it in transparent mode.

I'd love to know what others find most appropriate for their 
environments, particularly in WISP sort of environments.

Re: [WISPA] Dumb question?

 Easy, the current Wimax MAC (802.16d and e) was designed for licensed

I'll have to admit believing some of the WiMAX hype until I heard this 
fact several months ago.

The only people I see taking WiMAX seriously are service providers and 
carriers, particularly those who want to preserve their spectrum.  They 
don't have to worry about competing noise because of their sole license.

In many of these cases, they are buying the equipment for little more 
than to preserve the right to do what they want on that frequency.

Is this what others are seeing also?

[WISPA] 5.9 GHz ITS

2009-04-12 Thread Rogelio
Has anyone here implemented the 5.9 GHz band for ITS (Intelligent 
Transportation Services)?

I'm looking at some projects that might be a good fit and have recently 
started researching vendors that do it, as well as some of the 
regulatory characteristics of the band.

[WISPA] STP for redundancy on two panels horiz/vert oriented?

2009-04-12 Thread Rogelio
Using a dual 5.8 GHz radio solution, could I conceivably give myself 
some sort of redundancy by doing the following:

--two 23 dBi panels, one on each radio
--on panel for horizontal orientation; the other, for vertical
--put a switch on both sides that supports spanning tree

I have LOS between these radios, and I'm assuming that it would be rare 
to have both polarizations go out at the same time.

Does this sound conceivable?

I'd take a serious look at Juniper.

e.g.

All the hard core routing and switching experts I know laugh when 
someone suggests Cisco.

Cisco is like the WalMart of networking equipment.  If you need 
something, chances are that they have something there that will mostly 
do what it is that you need.  But if you need something for some 
specialized need, then chances are you need to go to Juniper, Foundry, 
Nortel, etc.

Thanks, Charles.  I'm fairly up-to-speed on that.  Once I knew a little 
bit about it, I googled and read up on what it is and which vendors had 
solutions to prevent against it.

I guess at this point I don't know what I don't know (if that makes 
sense).  I work on the Wi-Fi mesh portion and often rely on these PtP 
vendors to transport data back to a datacenters and find myself 
believing whatever they say on the topic because I'm not really sure 
what's up.

I've developed a relationship with the Bridgewave guys and have been 
impressed with them.  At this point, I'm basically a one trick 
Bridgewave pony and am hoping to change that. :)

Thanks for your response!

[WISPA] getting up to speed on various PtP microwave solutions

2009-04-04 Thread Rogelio
I've just recently started becoming familiar with the various microwave 
e band PtP solutions (Bridgewave, Dragonwave, Gigabeam, Loea, Trango, 
Proxim, etc). Before this, I knew nothing about things like rain fade or 
the various characteristics of bands in that range.

Does anyone know of any good tutorials for this sort of thing?  In other 
words, say I have a project with various high capacity PtP requirements 
and need to find the right technology and vendor.

Any suggestions on where I'd go to start?
