Re: [WISPA] Splitters with Motorola Canopy 320 - Results Update
The luxul snake oil worked no better than a 6dbi omni, cost signifigantly more, and stacked two four port splitters after a two port splitter. It was a mess.

Jim: I don't have the data sheets for them, actually they (my techs) assembled everything while I was in Vegas. We've gone ahead and converted more clients over to it today, and speeds/latency are just the same when it was one sector.

Re: [WISPA] Splitters with Motorola Canopy 320 - Results Update
I have often wondered if it would be better to have two antennas in one given direction, with one being \ pol and the other antenna being used for / pol. I wondered if special diversity would allow us to achieve better penetration results to clients without using splitters. Basically order the two of the standard moto antennas, but use one polarity on each.

Re: [WISPA] Splitters with Motorola Canopy 320 - Results Update
Eric: The whole purpose of this test was to create an omni effect. You're talking about something totally different, and I have often wondered that as well. I think there was a company that did this a long time ago, Luxul maybe? You would buy their antenna array..and they claimed a lot but nothing materialized out of it AFAIK. Jim: I don't have the data sheets for them, actually they (my techs) assembled everything while I was in Vegas. We've gone ahead and converted more clients over to it today, and speeds/latency are just the same when it was one sector.
