I have an 8db omni and a couple of feet below it a 14 db panel pointed to the main access point, both vertically polarize. On either antenna alone the RSSI fluctuates 30-50% and the dips were enough to cause the clients to drop out. With both antennas there is about a 10% fluctuation and connections are solid.   I was planning on deploying several more of them in some problem areas, but now that they have been discontinued I guess that is out.   John ----- Original Message ----- From: Dave Covert To: [EMAIL PROTECTED] Sent: Sunday, August 17, 2003 06:59 AM Subject: RE: [smartBridges] Wireless repeater rig What particular configuration with an omni and a panel are you using?  We have lots of multipath here as well...   I second the notion of the diversity feature on the aPPO for those places where an XO will be over-kill (unless the XO costs the same as an aPPO)   Dave Home Wireless -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of John Banes Sent: Sunday, August 17, 2003 8:19 AM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] Wireless repeater rig We have not tried that particular configuration, but we are using a panel antenna and an omni on one APP. We originally listened to those that said it wouldn't work, but in desperation gave it a try. The fluctuating signal we had going to the main access point leveled out and the clients are no longer experiencing disconnects. We are dealing with lots of multipath and reflections so this might not work as well if you are dealing with pure line of sight.   Supposedly there is also a loss of throughput while the unit searches for the correct antenna, but we have not noticed it to be a problem in our application.   John ----- Original Message ----- From: Dave Covert To: [EMAIL PROTECTED] Sent: Saturday, August 16, 2003 08:14 PM Subject: RE: [smartBridges] Wireless repeater rig Sounds like you have tried this? (two antennas) Has anyone tried it and have any experience to share?   The smartBridges site says 'airPoint-PRO� automatically selects the best signal'. What I am proposing is two use the two antennas in a cross polarized fashion so that the backhaul antenna can't hear the local traffic and the omni can't hear the backhaul traffic. It seems that the diversity feature would have no trouble picking the correct antenna since the 'off' antenna would be almost completely devoid of signal.   Can I get sB's thoughts on this?   Dave Home Wireless Company -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Billy Huddleston Sent: Thursday, August 14, 2003 8:28 AM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] Wireless repeater rig Bad idea..  Using the diversity feature of the aPPI won't buy you anything and, in fact, would hurt you in allot of ways.  1) The antennas need to be "balanced", using different antennas on each port would cause wonky things to happen.  2) Your throughput would be cut in half.  3)  Your going to get sporadic connectivity and even worse throughput using unbalanced directional antennas... and a good possibility that it wouldn't work at all!   I would suggest using to aPPI's back to back wired with a crossover.  OR use two aPPO units... Or if you simply have to use a single aPPI, use the a single antenna.   Thanks, Billy ----- Original Message ----- From: Dave Covert To: [EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 10:59 PM Subject: [smartBridges] Wireless repeater rig I need to make a POE-powered sB repeater box to 'light up' an area. Since the speedTrap-2 isn't out yet (want a beta tester? <g>) I need to make one. What I envision is an aPPi running repeater mode in a NEMA box. Each SMA antenna port on the aPPi would have a pigtail to a bulkhead mounted N-type connector. To one connector I attach an 18dBi panel pointed back to the tower and to the other connector I attach a 6-9dBi omni cross-polarized to the big panel. Customers within a couple-hundred feet use an aBi thru walls to talk to the omni. Clients a little further away use aBOs with little panels pointed at the omni.   I am guessing someone has done this before... would you mind divulging the part number and supplier of the parts you used? Specifically... NEMA box to house the aPP and pigtails? SMA to bulkhead N-type pigtails?   I am guessing the aPPi will work on POE outside in a NEMA box? Do you have to take the aPPi board out of the factory box when you put it in the NEMA box to keep it from getting too hot? (double insulation).   Dave Home Wireless Company
