RE: [WIRELESS-LAN] Investigating Wireless Back Haul

2007-02-24 Thread Frank Bulk 
Network Computing magazine just finished a review of some unlicensed
wireless gear that will be published out in a near-term issue.  It wasn't a
direct comparison and we didn't test any licensed gear (using licensed
spectrum is a problem for test houses), but it will give you a good idea of
features, throughput, and functionality (QoS, VLAN tagging, etc).

Kind regards,

Frank

Mike,

There are many options to consider.  One option is how they connect
to your equipment.  You may need new routers or NM modules to accommodate
the link between the device and your equipment which can cost anywhere from
3 to 9 thousand dollars at each end of the link (some devices connect via
fiber, while others use RJ-45).

The next option is bandwidth.  Some devices give you 50Mb, while
others give you 1Gb.  There is also the duplex level to consider.  Earlier
Proxim quick bridge models gave you half duplex.  Most products today give
you full, but there are still a few that give you half.

To license, or not to license - that it the question that you need
to ask yourself next.  Licensed links are protected by the FCC against
interfering links going up along your path.  Those are typically slightly
more expensive, but might be worth it in the long run.
 
I have dealt extensively with Proxim, and found their tsunami 480
products highly problematic (read: avoid at all cost).  Bridgewave and
Ceragon are good choices.  Look into those.

The Ceragon's are software upgradeable from 50 to 200 Mb FD and use
an RJ-45 connection.  The Bridgewave's use an MMF connection, and range in
bandwidth options up to 1Gb.

Feel free to contact me directly if you need any further help.

Hello,

I am investigating wireless back haul products as an option to reach a 
remote area of our campus.  It is not feasible to run either copper or 
fiber to the location.  However, line of sight is possible.  I am 
interested if others have set up wireless back haul links and what 
products they have used.

Products that we are currently investigating are: Proxim's (Terabeam) 
Terabridge; ZyXEL's fixed wireless back haul; and Canon's Canobeam. 

Any information that you may have would be appreciated.

Thanks,
Mike

Yes, RF backup is a good idea, which is why I like the LightPointe.  There
are only 3 or 4 more FSO vendors, and I can't recall if any more of them
have built-in RF backup.

I didn't start working with them until they came back and then they were

I just hoped for the best, but long term support is definitely a

It seems a some are considering two links, one FSO and another in the 60-80

We're in the process of installing a pair of BridgeWave GE60s to connect 
an off-campus site where we can't easily pull fibre. We also have a much 
older and much slower (45Mbps?) point-to-point wireless link whose name 
I can't remember it's so old, that we will replace this summer with a 
BridgeWave. That one has worked flawlessly for several years; summer, 
winter, rain, snow, you name it. Its only problem now is that it's too slow.

Based on the set of products you mentioned, I'm assuming you're seeking 
Gig class transport over a relatively short distance with line of 
sight.  Couple of others that are similar to Terabeam (millimeter wave) 
are Loe'a and Gigabeam.  We have a Loe'a link providing a prod GigE link 
over a short, over-water hop (you'll need to pay attention to rain fade 
... no snow issues for that link ;-).  We also tested FSona (optical) a 
few years ago to support GigE to a conference (hotel) venue.  Feel free 
to contact me offline if you want the gory details.

We did a trial of Canobeam some years back.  It was cool until it started to
snow.

We installed a pair of Canobeam DT-110 devices (FSO) for a similar
scenario.  We have been pleased with the reliability and performance.
Let me know if you'd like more information.

Subject: [WIRELESS-LAN] Investigating Wireless Back Haul

Hello,

I am investigating wireless back haul products as an option to reach a 
remote area of our campus.  It is not feasible to run either copper or 
fiber to the location.  However, line of sight is possible.  I am 
interested if others have set up wireless back haul links and what 
products they have used.

Products that we are currently investigating are: Proxim's (Terabeam) 
Terabridge; ZyXEL's fixed wireless back haul; and Canon's Canobeam. 

Any information that you may have would be appreciated.

Thanks,
Mike
