I have found the best tool I have ever seen for a WISP
This simple power meter allows you to see the output power of a card.. it can help you check cables, cards, and antennas.
Here is some startling info I found out.
I tested 5 SR5s and 5 Senao 200mW prism cards
Senoa Prism gave 200mW/24db output everytime excpet once. 1 card put 17db.. that card is now set aside as bad
SR5 .......100mW!!!!!!!!!!! max db is 20 and that is after setting tx-power to all fixed rates and then setting 30db!!!!!!!!!!!!!!!!!!!
this happens on all SR5!!!!!!
hello?? there is something wrong here.
I use mini-pci board with routerboard 14 4-min-pci -pci card. I read the specs and it says max power for each slot is 2.5watts.
We looked up the specs on the SR5 and did the math. You need 5.25 watts for full power. So I got got out my routerboard11 1mini-pci -pci card and it says it can do 5watts.
only 100mw on those as well. I tested on other hardware platforms as well and still on 100mw of power. I would name the other hardware, but I dont want my post deleted.
I think there is a major problem here. I hope someone else can buy the power meter and do the same tests.
I think we really need to bang on this hard, I am looking for some kind of hardware that can support the full 400mw of the SR5.
I talked to my vendor who resells Sr5 and he said Ubiquity told them when they announced the cards that nobdy could support the power and that the motherboard companies would have to catch up.
The biggest problem I see is that I can get 200mw out of the prism card, but only 100mw out of the SR5. I would be happy for now for 200mw out of the SR5.
other than that the power meter is great for finding bad cables and pigtails and such. Since I have bought it and gone out to all my nodes, I have found and replaced ~10 cables. Some had much more loss than others.. some lost 10db!. But now that I can sit at the bench and test cables, I was able to replace the cables with known good ones. This has increased my performance alot. I can now get 10megs 5 hops out
