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 high

Mine seem to be running steady at 27-28 W at 256QAM but with lower modulation they drop a little. Wed, Sep 29, 2010 at 07:03:53PM -0400, Josh Luthman wrote: > My lumina in the lab was 35 watts for 0dbm... > On Sep 29, 2010 6:57 PM, "Patrick Cole" wrote: > > Thought I wo

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 hav

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 su

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 limi

I would steer well clear of that UBNT bridge for something as critical as you describe. At the price point it just screams disaster. I've not used the Ligowave MIMO radios however I have used the LigoPTP 5-N and I was a little disappointed. The lack of QoS is a definite negative. We had one of

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 w

Paul, Are you redistributing any other routes into OSPF? When you do this it will make your router an ASBR. Pat Fri, Mar 26, 2010 at 11:05:25AM -0700, Paul Gerstenberger wrote: > The best way to transition from our switched network to routed that I can > figure is to set up the existing VLAN

Hi all, Proxim's new 3x3 and 2x2 MIMO based radios... The local proxim rep is pushing these products very hard and the price looks very competetive, has anyone used them and can comment on how they perform with regards to performance, reliability & features. Regards, Patrick Linear G --
