Re: [WISPA] PPPoE Concentrator Redundancy
Scott, Typically in this scenario I would recommend one of two things: 1) Use an MPLS VLL/L2-psuedowire with a secondary failover endpoint on one side. Only some equipment vendors implement this (Juniper being one of them) 2) Use a PPPoE pado delay. Set one BRAS to be some decent amount higher delay in sending out PADO packets. Any decent BRAS should support this. This does not include Mikrotik to my knowledge. With a Cisco BRAS you can use the following command in a BBA group in 12.4T+: http://www.cisco.com/en/US/docs/ios/bbdsl/configuration/guide/bba_pppoe_sss.html Regards, Patrick Tue, Nov 02, 2010 at 11:36:01PM -0700, Scott Vander Dussen wrote: Cross posting from another list for different opinions.. We're looking to have more than one PPPoE Concentrator available so that if one goes down due to catastrophic failure, the customers associated to that concentrator will rollover to the next one. However, the concern is that because the initial connection is layer 2 that both concentrators may see the same connection attempt and authenticate both. Is there a real effective way of having two concentrators that either load balance or provide redundancy? Thanks, `S WISPA Wants You!

Re: [WISPA] 11GHz fade margin
Thought I would chime in since I'm using the SAF lumina in my network: The standard Lumina at 11GHz does up to +12 dBm at 256QAM and +19 dBm at QPSK.SAF designed this radio specifically for lower power applications (solar etc). and has a typical power consumption around 25W per unit. They have a high power model that does +25 at QPSK and +17 at 256 QAM at 11GHz. Pat Wed, Sep 29, 2010 at 06:18:28PM -0400, Tom DeReggi wrote: Why Exalt over Dragonwave or SAF?

Re: [WISPA] Proxim QB 8150
All poles have only have a limited level of seperation. Most horizonal and vertical dual polarised antennas only have about 30 dB of seperation between the poles. You will notice if you use two radios of similar frequency on different poles of these antennas it does not work well due to the limited seperation. The techniques used in MIMO radios do not require absolute seperation, just enough spatial diversity for the DSP to be able to differentiate the signals to a point. Different polarisation certainly achieves this goal. You could use the same polarisation from three different antennas and still get spatial diversity. Over longer distances though it becomes harder to differentiate the signals which is why we tend to add the different polarisation to different antennae to increase the diversity.

Re: [WISPA] Proxim QB 8150
Spot on; in the case of the QB8100, the third pole does not add any additional carriers or throughput directly. It does serve to improve sensitivity/receive levels due to the spatial diversity. This will help increase throughput and reliability in noisy or multipath prone environments as Tom suggests. Tue, Apr 27, 2010 at 09:40:47PM -0400, Tom DeReggi wrote: No because... they may not all get used for Transmit and Receive. technically, for a well designed product using some sort of time space delay as the mechanism for seperation, having pol diversity is not necessarilly required, as polarity is not the technique to acheive seperation. It also is relevent to whether the goal is to have each antenna have the same data to improve RSSI or different data to increase speed, as if it was the same data, it would be fine to transmit all at once. I do not know how Proxim is using Pols. I'll also mention, regarding receive, there is a benefit to receiving on all three with spatial diversity. Slant is only 1.5db of seperation from each of teh otehr two pols. (45 degree off pol only yeilds 1.5db loss) If one side transmits on both H and V, the other side would use multiple RX antennas as mechanism to hear more reflection to combine into the signal for better gain, and the Slant would hear both the Vert and Hor pols. So if the Verticle got killed by multipath or some other RF barrier, and Horizontal made it through, the Horizontal and Slant antennas would both optimally hear the Horizontal singal within 1.5 DB, and be combined to assist gain. I do not know that this method is the best use of 3x3, but it is one possible use of 3 poles. .

Re: [WISPA] dry copper solution
At 3 miles, VDSL is not a good solution. That is a very long loop length. VDSL2 does not use 2 pairs. In fact, VDSL2 is designed to fall back to ADSL2+ modulation when going beyond the beneficial limits of VDSL (~ 2km). Most ethernet extenders also tap out around 2km. The only real option you would have is G.SHDSL point-to-point modems with multiple pair bonding. G.SHDSL supports 5.6mbps per pair, however, this speed is only attainable up to about 3km. at 4.8km you would be getting probably less than half of this per pair.

Re: [WISPA] Mikrotik and OSPF multi-area configuration
Paul, Are you redistributing any other routes into OSPF? When you do this it will make your router an ASBR.

I've had a backbone area set up between our Riverstone (ASBR) and mikrotik routers (ABRs), and now I've created the additional areas for the three vlans. The riverstone has the default route out of the network and is DR for backbone area 0 and is only a member of area 0, so it should be the ASBR. By my reckoning, the backbone mikrotiks should be ABRs (members of area 0 and 1, 2, 3), then the tower site mikrotiks will be members of 1, 2, OR 3. But, they're all showing as ASBRs, and I'm not understanding why. They're all only running OSPF, and there is only one router (only in area 0) with a static default route out of the network. Any thoughts why I'm seeing this? Here is a simple example of my OSPF configuration. In reality the IPs are different and there will be more routers in each zone, but first things first...: Area 0 (broadcast), 10.0.0.0/27, riverstone-1 ASBR is 10.0.0.1 and mikrotik-1 ABR is 10.0.0.2 Area 1 (NBMA), 10.0.0.32/27, mikrotik-1 ABR is 10.0.0.33 and mikrotik-2 @ tower A is 10.0.0.34 Area 2 (NBMA), 10.0.0.64/27, mikrotik-1 ABR is 10.0.0.65 and mikrotik-3 @ tower B is 10.0.0.66 Area 3 (NBMA), 10.0.0.96/27, mikrotik-1 ABR is 10.0.0.97 and mikrotik-4 @ tower C is 10.0.0.98 Thanks! -Paul WISPA Wants You!
