Re: [WISPA] Canopy PTP400 software?

2008-06-09 Thread Allen Yu
Hi All

The website address to download software (and user manuals/release notes) is

http://www.motorola.com/ptp/software

To access the software downloads you are required to enter a MAC address of
a unit that is under 12 months old (or purchase a Software Maintenance
Contract)

The MAC address is sometimes referred to as the ESN.

You can find the MAC address of PTP products by either

1) Looking at the label on the rear of the ODU
2) Look at the System Status screen of the management interface

Allen

   Hi, someone here have some idea how to solve the problems i~m getting
   with the Alvarion VL gear?
  
   I bought some AU and SU 5.4ghz and a B100 5.8ghz 100mbits) ffor  a ~5
   miles link, for start replacing my motorola canopy network ( we now
   need more troughtput and pps ).
  
  
   I first deployed the AU with a 120º Sector  and a 4 Su 6mbit version,
   the Su ara really easy to align but i got latency and upload traffic
   problems, i can get a steady 5mbits downstream but about no upstream
   traffic.i already tried change the modulation lavels, atpc, tx power,
   all freqs , lower the channel bandwidth. available but no go.
  
   Today i deployed the B100 and i´m having the same issues as the VL
   gear. but worse, only a spiky 3 ~4mbits downstream traffic and about
   2mbits upstream for a radio capable of almost 70mbits, whats is a
   shame. We are in a very crowded area, but the motorola canopy works
   perfectly in that area, but we got troughput issues with canopy.
  
   anyone here had problems like that with the Alvarion gear in a
   crownded 5ghz area?
   in the same area we could manage to work a Airlive Wla5000 (802.11a
   radio) from ovislink to work better then the Alvarion.
  
   Thanks in advice.

interface, does that combination will work?

 If they're only going to use 1 CMTS then you must get wireless links that
 shoot video, which will pretty much kill any IP wireless links in the area
 running on the same channel.

 A CMTS usually must have a management server for provisioning 
 management,
 so you could buy several cheaper CMTSs (I purchased a used Nortel/Arris
 CMTS1000 years ago and it's never had a hiccup) and place them at each
 site,
 linking them to the management server via wireless links.

 I've also investingated DOCSIS wireless radios (they'll just do the data
 part).

 The problem with all this is if you don't have some kind of circuits
 (wired
 or wireless) between the sites, then you'll have to have feeds for all the
 channels you're going to provide at each location.  Depending on mileage,
 you may be able to use dry copper circuits.  I know that some of this can
 be
 done over T-1 circuits, but the project I'm involved in didn't go that
 route, so I never spent too much time on it.

 Hope this helps.

  The areas are not connected by fiber and the problem they are facing
  is the way to extend the CMTS service to those areas. They have think
  in PTP radio links but the CMTS devices are not IP, so they should use
  1 CMTS for each area and that is very expensive.
 
  Is there any way to extend the CMTS coverage to this areas by using

Lets say a node can see two upstream nodes and two downstream

coming and going in a dynamic fashion, yeah I'm sure a specialized

believe somewhere around 30 or more mesh wireless (mobile) mesh 
protocols have been developed over the years each with it's own pros 
and cons.  I'm not thinking about anything mobile unless it is the

Please follow my train of thought for a second.  When using 
directional antennas, then a bit of aiming is required right?.  But 
the benefits are as you say.  Now such antennas need to be mounted 
right?  So this is a fixed wireless mesh we are talking here, not a 
mobile mesh with antennas in motion. What makes this possible is 
multiple radio systems (3, 4, even 5 radios).  So given all this, 
how would Meraki provide anything that say Mikrotik couldn't 
do?  Choose paths?  There isn't much to choose when using directional 
antennas on each end (PtP)  You know what's there already, one radio, 
the other end of the link.  So it is just a matter of switching 
interfaces to a second interface when the best interface goes down 
(if ever).  OSPF is pretty good at that.  Not arguing, just curious 
about all that.  Also I'm brainstorming possible configurations with 
an omni on one end and a directional on the other.  I need a couple 
of good cheap directional 900MHz antennas for some testing.  I have 
two omni's already and wasn't too impressed going omni to 
omni.  Signal started to drop off after about a quarter mile  or so, 
and that isn't going to cut it.

How come nobody seems to be using it?



The first Locustworld/meshbox/ultramesh deployment in the US was 
around 2000 a few dozen miles north of me in Vivian LA, (Fastline?) I 
met with the owner last year.  Basically he was an WISP worth about 
$20-30k with debt of about $100k+  I really hated to see that..


The thing about mesh is this.  If all nodes are stationary  that is 
one thing.  (Muni-wifi nodes on lightpoles for example)  If all nodes 
are roaming/moving that is entirely another matter.  I am beginning 
to believe that no mesh (TCP/IP stack) is required if all notes are 
stationary like NOC's and NAP's and Telco Hotels on the Internet are 
stationary yet meshed using BGP (without locustworld or meraki)... 
Roaming in an entirely different matter.  But meshes come often hand 
in hand with roaming which is too much to swallow all at once if you 
ask me.  If it was easy to provide a multi-MBPS service with roaming 
cellphone technology, (roaming) they would have done it by now. EVDO 
sucks in my town.  Faster than 1xRTT but still very intermittent with 
dropped connections.


Imagine a fire truck racing across town roaming from WIFI AP to AP 
without braking his TCP/IP socket.  That is true mesh.  Many mesh 
protocols and/or solutions don't address this issue of roaming across 
subnets which can be a TCP/IP nightmare on very large networks such 
as muni wifi networks.


Building a network that cannot scale in size is like building a time 
bomb, or at the very least, painting yourself into a corner.  My 
point?  I'm just asking why you think you need something else besides 
BGP or OSPF.  If your nodes move, then I gotcha, Use Meraki or 
whatever mesh protocol works..  Otherwise, what exactly is your 
problem with OSPF?  I'm just trying to learn more about meshing, and 
my comments are JMHO...

RE: [WISPA] The MOBL Sage (Warning: Long Post)

2007-09-13 Thread Allen Marsalis
Patrick, thanks for the follow up.  True, I am very fortunate and 
lucky indeed.  I did not loose any money with my shares and not all 
the ISP's can say that.  Some were only able to sell MOBL after it 
fell into the teens or lower.  I still have a beautiful wife and two 
healthy/smart kids.  And my Dad.  Friends that wish to help.  And 
a crazy new community website software package that I created and 
don't know what to do with!  :)

Quite a story Allen. I am aware of some minor parts of the MobilePRO
saga. Bruce Sanquinetti was the former president of the U.S. subsidiary
of BreezeCOM. He left BreezeCOM the same week I joined in August of
1999. He was a pretty mercurial guy from what I gathered by those that
had worked with him. I am glad he left (or was asked to leave, I don't
know which), because the corporate culture I have always worked under
and tried to foster is a much different type and Lord knows I don't do
well with autocrats -- I am, er, a bit too opinionated. I am now into my
9th year.

Anyway, after BreezeCOM Bruce went on looking for the Next Big Thing,
first trying to lead the old Wave Wireless out of Sarasota, FL. That did
not go so well and he went on to start-up a new chip company. That went
south and the next I heard was that he had joined MobilePRO. I think he
did that for only about a year, then left that too. I have no idea what
he is up to now.

Your tale is certainly a cautionary one. My advice to WISPs is that if
you are trying to exit via a sale of the company you built with your
blood, sweat, tears and personal dollars ONLY sell for cash. Fortunately
Allen you did get 1/2 in cash and you were smart enough to sell your
shares as soon as you could.

Yeah me neither.  But it is interesting to note that MobilePro's CEO 
(Jay Wright) was also at Wave Wireless (Speedcom) with Bruce back 
during that time functioning as their CFO.  The good ole boys

of the CEO (Jay Wright) and after he no longer ran the ISP's, he 
moved over to the Progames website division. But I'm not sure there 
was anything Jack could have done to save the day considering the 
Cornell financing deals, and ridiculous salaries, bonuses, and so forth.

Here is an additional cautionary thought FWIW.  I always had a great 
reputation and so did my company.  After I left, ShreveNet quickly 
went from being the best to the worse ISP in town. The employees 
scattered to the wind, but I'm still here. I thought it would be easy 
to start a new business however people do not forget and forgive so 
easily.  I even had one ex-customer jokingly call me a traitor years 
later!   You guys were the best!  Why did you sell out!?


I think my future customers will always wonder if I am going to sell 
them out again, which is always a possibility.  But I'm no 
quitter!  I outlasted a lot of Internet companies and upstream 
providers like uu.net Worldcom, Global Crossing, etc.  Anyway the 
moral of this lesson is do not sell out and expect to keep your 
career unscathed.  I would not sell my entire company again unless it 
was enough to retire on.

[WISPA] The MOBL Sage (Warning: Long Post)

2007-09-12 Thread Allen Marsalis



Hello Allen,

Good to see you back and doing well.  Curious to hear your take on the
MobilePro saga.  On or off list is good with me.




The  Friends

Quite a few people have asked me (A) what have I 
been doing lately? And (B) please tell me the 
MobilePro saga.  It means a lot to me that some 
of you have asked about me.  It has hit me that 
although only have a handful of friends here in 
town, I did have 100+ friends in this 
industry!  Thank you all for your kind thoughts 
and I do apologize for dropping off the planet 
like I did.  That was my loss more than anyone 
else's.  You are some of the finest people I have 
ever met in my life, besides my old ShreveNet 
staff.  You know how I felt about my crew.  Heck, 
you all helped me train them!  ;)



The Saga

I will start with the MobilePro Saga and get it 
out of the way and move on to more positive 
things like the goodthings I have been up to in 
the past year or two.  I tell you “The Saga” not 
as an excuse for my hiatus from the wireless 
industry, and excuse for my strange behavior, but 
well…….(get it? “Well”, that’s a deep subject, 
LOL) well………..because some of you asked me too 
(cough cough Brad Belton cough cough).


Here goes..

It is somewhat of an interesting story I guess, 
for inside industry people like us, or else this 
might be extremely Off Topic for this list.  As a 
WISP, this is not as easy story for me to 
tell.  Not a happy story for me.  I would like to 
tell the story and forget as much as possible and 
move on.  Perhaps there is something that you can 
learn from this (yeah like Allen is not so smart 
after all? – (Maybe and maybe not, you decide)



The Disclaimer

It has been over 3 years since the sale of my 
(W)ISP to MobilePro.  I am no longer under any 
agreement or obligation.  I am now entitled to 
express my opinion right or wrong.  This is my opinion and only my opinion.



The Beginning

Roll the clock back to 2004.  Life is pretty 
good.  Speaking at WISPCON.  Drinking Romulan Ale 
with some of the finest people on the 
planet.  (now argue that point)   Why on earth 
would I want to sell my company?  The WISP of my 
dreams?  Whatsup wit dat?   There were a whole 
host of reasons for selling out and many of which 
were personal some were reasonable, and some 
might have been downright psychotic.  Here are 
some of the reasons I had for selling, just in 
case any of you ever consider selling 
yourself.  That might be one of the most 
difficult decisions you ever make.  Choose wisely!


(A) I was not a “pureplay”.  We offered wireless, 
DSL, dialup, T1, hosting, web design, hotspots, 
you name it, I tried it all.  My problems began 
as I began to take a beating on dialup amid new 
competition with cablemodem and several DSL 
carriers.  I was bleeding revenues about 1% of 
month despite growth in broadband areas (DSL, 
wireless and T1) But I was all over the Northern 
state.  Not much DSL and T1 out there in the 
boonies.  And wireless was relatively a new trick 
for everyone back in those days.


I was debt free until 1999 when I acquired the 
second largest ISP in the area (I was the 
largest).  With this new debt, I borrowed even 
more to host all these new customers.  (The old 
ISP was using crap)  I got a good interest rate 
with the bank and with my father, both who backed 
me.  LOL, then we REALLY started growing fast! 
(mainly dialup)  So much of this debt was the 
result of left over baggage from the dial days 
plus the acquisition days and subsequent growth days.


I began looking into my crystal ball and began to 
worry seeing an ever changing future in 
broadband. (especially wireless) Would I ever get 
this debt paid off in time before I must prepare 
for the next round of change?  Then bang, my 
father came down with melanoma cancer in his 
lungs. This was right after Matt Larsen’s Dad 
died.   My Dad already had prostate cancer and 
basil cell carcinoma. (3 types total) at this 
time (04)  My doctor told me he probably wouldn’t 
see his next birthday.  He was 84 at the time.  I 
wanted to pay off my Dad before he passed 
away.  That was a major factor.  It was important 
to me that he be proud of his remaining only son.



The First Lesson

All Doctors aren’t always right.  My father found 
some new doctors with new ideas and had 3 very 
targeted lung surgeries (1 per year) and is doing 
remarkably well now for an 87 year old man.  I am 
very proud of him.  He is one “tough old bird” 
and just like the energizer bunny, he keeps going 
and going and going.  He still drives to his 
office every day for a few hours every day.  I’m 
on the 5th floor and he is on the 11th floor, 
still at 333 Texas all these many years. (He longer than I)


Also a part of this lesson is to use various 
domain names for unique services.  That way you 
can sell part and not all of a property. (as needed)



More Reasons

Around that time I suddenly had a “bad back”.  I 
didn’t know what was wrong with my back

From the conversations I've had with people trying to use, or just 
around, mesh gear, it doesn't usually work very well once the 
network starts to come alive.  The old hub and spoke method works best.


But the entire Internet is a Mesh of sorts.  Remember back in the 
90's how the internet was designed to withstand a nuclear attack? 
(using lots of hub and spoke and routing for redundancy)  My old 
friend, lets cut  through the image of mesh.  What mesh is in my 
opinion is the elimination of tall vertical realestate (expensive) 
and the adoption of low vertical realestate (free) such as lightpoles 
and rooftops.  Mesh means routing rather than bridging. Instead of 
shooting high for big supercells, mesh is a series of microcells or 
picocells down low (cheap).  Instead of dumping money into towers and 
tower climbers (sorry Bob my friend) mesh is made of equipment in a 
non-special environment.


Now you might think that mesh means use of omni antennas... Not 
so.  maybe, maybe not.  To me mesh means communication between 
multiple nodes (places) that are connected to each other in a web 
(like the Internet)  Strix is on th right track.  But like so many 
manufacturers, they are better at shipping gear than designing 
business plans for others to invest in (like MobilePro).


But I do not believe in throwing out the baby with the 
bathwater.  Strix had something (before they laid off half their 
staff this month).  They chose folks like MOBL to cater to rather 
than you or me.  I believe there is a market for 900 rural mesh 
sub-muni networks.  Am I wrong?

Some of the new mesh gear uses different channels for broadcast 
vs. backhaul.  But that's not really mesh anymore, it's hub and 
spoke stuffed into a single box.


I'm told that if you insist on running mesh, at least make sure that 
it never goes more than 2 or 3 layers deep.


Personally, in your area, I'd run 900 to mini pops.  In the 
population centers I'd run small micro cells of wifi.  Good speeds, 
cheap installs, lots of flexibility etc.


It's good to see ya back.  This biz is like a good drug isn't 
it.  Once you are hooked, you can never get very far away.

I was a WISP in the late 90s and early 00s. Some of you may know

years, I have pursued new interests but I keep thinking back on my 
experiences as a WISP. I had a lot of good times back then.  I'm 
thinking about creeping back into the WISP business.


After I sold in 2004, I followed a new trend in wireless in the 
press called muni wireless promoted by manufacturers such as 
Strix and Tropos. This concept has taken some major blows in the 
press this month:

Hi,

The biggest problem I see when looking at mesh is having access to 
all those locations... people's homes, light poles, telephone poles, 
whatever. You now have to install UPS systems, rebooters, have the

Bingo, I didn't say anything early on, but you hit the nail 
Travis.  The biggest problem I see is the un-even-ness of property 
ownership in my plan (rural tier 4 areas).  Fortunately as you move 
into a town, pieces of land keep getting smaller and smaller.  My 
only solution is to deviate from the use of omni antennas towards 
directional antennas to increase the distance between nodes from 1 
mile to maybe 2 to 4 miles between nodes.


But here are some very loose number regarding muni wifi.  By 
comparison to my plan, imagine 15 to 20 nodes per square mile at 
$2500 to $3500 per node.  Usinging standards based (generic) hardware 
I think I can reduce that cost to under $900 per node.  Now imagine 
if a 900MHz AP with omni works to 1 mile radius, or 2 miles 
circumference.  This is nearly 4 square miles of coverage for under 
$1k.  (less than $250 per square mile).


This is almost like averaging between the economics of fixed 
wireless and muni wifi networks.  But in my areas, that might lead 
to 4X success rates in site surveys..\

[WISPA] Thoughts on 900MHz mesh networks

2007-09-10 Thread Allen Marsalis
 to do with PtP shots. But any 
thoughts or feedback on 900MHz meshing is appreciated.  I do see a 
few problems with this concept, however I am at the stage where I 
think some feedback might be helpful.  I'm hoping some of you 
followed the muni wireless trend and gear from Strix, Tropos, Belair, 
etc.  Not all their ideas were wrong or bad.


One last question or two if I may.  Is there only one manufacturer of 
900MHz mini-pci cards? (Ubiquiti SR9) Also, do you think it is it too 
late in 2007 to start a WISP?  ;)  Last, would 700MHz system 
eventually creep in over a few years and eat my lunch?


Thank you all and as always, good luck to all WISPs!

Best Regards,

You 900 idea souns interesting, but youll need a 900 muni client and/or
900 pcmcia card for customers



Thanks much for the reply Gino.  My idea is like muni wireless in 
that there really is no CPE per se.  With muni wifi, each node is on 
top of a light pole or building.  With my idea, I would place a pole 
in the yard (or rooftop) of select customers to form the NLOS 
mesh.  Each box would have at least two 900MHz cards plus one wifi 
card for the customer to access using a laptop (or desktop with cheap 
wifi adapter).  Like with muni wifi, I would own all the rooftop and 
poletop outdoor gear.


But in a sense you are correct.  In fact it would be more like two 
900 cards per customer if you are not at the edge of the mesh.  I'm 
able to get 0.1 miles of NLOS using wifi so in theory, next door 
neighbors may not need any 900 (not be a node in the mesh)


One goal is to reduce the need for towers.  A climber fell to his 
death here only a few months ago, and I can't afford expensive tower 
space and climbers anyway.  I'd rather put that capital in to more 
gear to grow the mesh organically.


I take it that nobody has ever built a 900MHz NLOS mesh network 
before.  Which is not a good sign to me.  That's a sign that my idea 
probably won't work.

Alan,

There is a second manufacture of 900 Mini-Pci cards which is Zcomax. The two
(ubnt and Zcomax don't talk because of different center frequencies. Zcomax is
what Tranzeo is using in there 900 products, so this may be a good way to go,
with the ability to have pre-manufactured client radios. What I have found
with any Atheros card running 5Mhz channels, is that if you scan from another,
you will see the first card transmitting on a channel about 20mhz away. This
transmit is about 20dB less than the primary, but still prevalently there. I
think you could see some issues because of this, and I wonder what frequency
that ends up being when the 900 card is a re-badge of 2.4. To explain this
better, channel 6 on 2.4 is 906 on the ubiquity cards I believe. If I then
scan and see a signature at 2457, what frequency is that on the 900
conversion? It is probably in the high 800 range by my estimate. There are
definitely some issues there.

Also, I have seen better connections with Motorola 900 than with the put
togethers. I do think your idea is something worth while, and I've thought
about something similar myself. I am also familiar with the Muni-market, and
the downfalls, and the good ideas of it. If you remember me, you know I worked
for one of them. In fact, I worked under you I believe!!

 I was a WISP in the late 90s and early 00s. Some of you may know

 years, I have pursued new interests but I keep thinking back on my
 experiences as a WISP.  I had a lot of good times back then.  I'm
 thinking about creeping back into the WISP business.

 After I sold in 2004, I followed a new trend in wireless in the
 press called muni wireless promoted by manufacturers such as Strix
 and Tropos.  This concept has taken some major blows in the press

Thank you David for your thoughts on this.  I too am a bit 
skeptical.  :)  Which is why I decided to ask for comments from you 
guys.  There is the additional issue of mesh routing protocols but 
I think (and I mean think) I may have that covered if the physical 
stuff worked out ok.  It's just the whole concept might fall flat for 
a dozen reasons.  I'm trying to figure out how many nodes I would 
need to deploy in a real world test, but I also want to think this 
out before getting that far and spend a bunch of money.  The idea may 
be so bad that testing is unwarranted.


But hey, there must be at least 8 people left in the country without 
broadband, and I want to give it to them! ;)

I'd be very skeptical just because of what I lovingly call the 
Tropos Effect.


Obviously, all these nodes eventually have to come back to... 
somewhere that has a big bad Internet connection. Your office, a 
central tower, whatever. If you're near that tower, you don't have 
much of a problem, as your laptop is talking to a node that's 
talking directly to that point of origin. If you're a few blocks 
away, where your laptop talks to a node that's two or three hops 
away, there's cumulative bandwidth loss and added latency, and just 
more things that can go wrong generally.


Your proposal gets rid of the worst part of how Tropos does things. 
They use the same radio both for inter-node communication and for 
customers, same SSID, same everything; by using separate radios for 
backhaul and customer access, you're already coming out ahead.


There will still be added overhead and latency, the more nodes you 
have to go through, and the folks at the farthest reaches of the 
network won't have as good an experience as the folks close to your 
point of origin.


I'm a bit skeptical. The expense of 900MHz gear, and the sheer 
number of units you'd need to for a wide coverage area, makes this 
seem like a really difficult idea to pull off. Nevertheless, I wish 
you luck, if you do choose to deploy something like that.

petitioning the FCC for nationwide prime spectrum?  I'm short a few 
billion it seems..  Even if my idea is technically doable, then I 
must go find the right markets which is a challenge all in itself.  I 
sometimes see data centers and there aren't many dialup customers 
left and lots of empty modems.  How Netzero can still afford to run 
ads I do not know.

Myself, I would only look at 900 as a temporary frequency to use. 
Maybe a couple years, more in the very rural areas and less urban wise.


Too many others are using 900 or starting to use it. Electric and 
water companies for meter reading, walmart and other bigbox for id 
and our portable phones still use 900 even when their 2.4 or 5.8.


So if building something out and realizing it has a short time span 
works. Then 900 is workable.

Re: [WISPA] Thoughts on 900MHz mesh networks

Allen,

It sounds as if you might be proposing this for a suburban or even
tree filled urban environment. One problem you might run into is
clear spectrum in 900MHz.  I've use Trango gear out in rural areas,
where it works OK. I've only done a few scans in the city (East
Lansing and Lansing, specifically). Both of those scans were so
depressing I never tried making any links with 900 in town. All the
channels were what the Trango manual calls unsuitable.


Point noted.  My testing thus far has been at my house which is in an 
remote community a couple miles outside of town.  Results may and 
probably will vary and I get closer to town, but I'm not wanting to 
compete with cable or DSL.  I was hoping to find some still under 
served small towns that would appreciate my services..





I have a few of the SR9 cards and am just starting to work with them.
I read somewhere that Trango (for example) rejects interference
better than the SR9. No personal experience one way or another yet.


I saw were Ubiquiti has cavity filters but I have no idea what they 
cost or how well they work.  I had one Trango 900 POP years ago and 
it worked well.  But 6 sectors ain't happening. (I had only a few 
customers off one sector)  But I'm really thinking in terms of 
multiple radio systems (SBC's) for a number of reasons.





My new rule of thumb with Trango is that I can go 2 miles.



I recall a little bit better for me.  But the spectrum may have been 
really clear.  I didn't have a 900MHz option for my cheap spectrum 
analyzer.  I sold my company not long after hanging that gear.





You might consider a modified mesh structure that uses 2.4 or 5GHz
(or even 900 after testing) to those few LOS houses, then something
like Meraki mesh to connect close neighbors.


Nodding, I have thought in terms of large outter mesh with an inner 
micro mesh structure that isn't intended to go very deep (lots of 
hops)  But out in the boonies, I'm not sure 2.4/5.8 is going to get 
me very far  when houses might be a quarter or half mile apart. (or 
more)  If I did have a tower in the area, perhaps breaks in the 
mesh could be patched with a new homerun shot if you follow me.


Thanks for the feedback

Allen

Metricom's long out of business, but technologically, they made it
work (albeit at ~28 Kbps, and later ~128 Kbps). One of the key things
they did to make it work at 902-928 MHz is to use FHSS and small
channel sizes rather than fixed, wide channels as all the current
902-928 MHz BWIA gear (except Alvarion's BreezeNet [?].


I clearly see your point as an old FHSS guy.  hehehe

LOL, between you and me, I would never have waxed so philosophically 
over this idea had it not been for the muni-wifi movement with its 
limited non-overlapping channels. Multiple radio systems got me 
interested in meshing a while back.  I guess I'm not the only one, 
but my market is definitely not city wifi like Strix.





The earlier version did both mesh and access using 902-928 MHz. The
newer version used 2.3 and 2.4 GHz for the mesh (backhaul) and 902-928
MHz for access only.


Gotcha, many thanks for responding to me Steve.  I think there is 
something to be learned under every new stone, and even some old 
stones long forgotten my most...  I barely remember Metricom and 
packet radio.


Hmmm I just saw a HughesNet commercial.  The one with the pretty lady 
in a green dress.  I assume GEO satellite service still stinks to 
high heaven??  I nearly forgot about those guys...  I once knew Avi 
Freedman when he was into some satellite stuff and learned enough not 
to be too scared of the sat guys who have their own unique set of 
expensive problems.

I was only about a half year off.  Not bad for an old man.  :)   I'm 
not sure I remember your youngest though.  A belated congratulations 
to you!  I know you are proud of them both.  My son is now a freshman 
in high school and has outgrown me already.  Homecoming is this 
Saturday.  Wow how time flies. My daughter is 9 and in a few more 
years, she might be taller than me as well..


Yeah got one of those old BreezeCom shirts in XXL?  That is, if they 
aren't collectors items by now... ;)

Re: [WISPA] remote power control

I have used one of these for a year now and like it.

Allen

 Hi,
 Since I've heard some not-so-good experiences with the APC
 MasterSwtich, I went looking on the web.
 Ebay led me to this product, has anyone used this power control
 device?  Any feedback on it?

 Thanks.

Re: [WISPA] TV Interference

2005-10-04 Thread allen
Channels 2 - 6 on TV are below the FM Radio broadcast band.  Perhaps an IF
of the internet radio is leaking into the TV system - Do they have a mast
mounted TV amplifier in the chain?

 font size=2OK, I have dealt with TV interference before, but this one
 has me stumped.  Installed customer 4 weeks ago.  All is fine.  Over last
 week, signal strenght started degrading.  Customer complained about speed
 slowdown.  Customer was out of town for weekend but we went out Saturday
 and RSSI was really bad.  Did some testing.  Replaced 15dB antenna with a
 19.  Raised about 4quot;.  Signal strength improved dramatically. 
 Customer came home Sunday and there were dots/lines in channels 2 and 5. 
 Channel 7 works fine.  The 2 amp; 7 transmitters are not far from each
 other.  Unplugged radio and dots/lines went away.  Plugged it back in,
 dots/lines.  So, why only channels below 7 and why only with the new
 antenna?
