I would suggest using the backhaul method with ROBIN nodes on the ends

what hardware are you going to use? if you are dead set on directionals. go with the EN2610 with the biult in directional and then bullet 2HPs with omnis on them.

honestly for the distances you are going, one bullet with onmi at the red dot and then bullet 2HPs with omnis at the AP locations would work fine.

i am rather new to omni-directional antena's. for most of my applications I use a distribution system where I have the modem plugged into a gateway and then a few repeaters. this does not always work however so I have been talking with streak wave and they recommend a pico station 2 hp with

"12dbi 180 degree 2.4 ghz, upol, sector."

there giving me a pigtail converter so that it will fit on the pico.

we will be placing 2 of these, 1 of each at the blue dots shooting at the buildings where i have drawn the triangle.

how does this look. what possible challenges if any will i run into.

(look at the image at the top of the post for reference)

that would work as well, to connected the network together, but how are the clients going to connect? if the clients are on the wrong side of the 180° sectors they will not have any signal to connect to the AP.

sorry for the simple drawing. but you get the idea. each node will connect to the gateway (the DSL connection) and clients will be able to connect to any node (including the gateway)

if you make all the node have a 180° sector, then anyone behind it will not have signal. take those circles I drew and cut them in half.

i see what you are saying and the reason i was going with the 180 is that for 1 i have never used the directinal antenna before and i wanted to know from a cost persepective if i can feed signal to those buildings with just 2 directional antenna's or will i have to put repeaters in the units to handle the frequent bidirectional problem.

(i feel like if i put pico station 2 hps's with stock antenna that it blasts signal but does nothing for conectivity it seems that with whatever site i have with a pico station 2 hp i need an om1p just so the laptops can use the network.

assuming we have a good firmware and working ps2hp's will the stock antenna on the pico's work for this application?

I have a bullet 2HP above me about 45 feet on a tower with a 7DBi omni. (directly above) and even thought the roof is aluminum I can connect and surf that AP just fine with a laptop.

I think the problem you are seeing with the picos is that they have a 6Dbi omni. Put a decent omni on those and the pico HP has plenty of power to do what you want IF you put on a good omni. (honestly it is the same unit as the bullet 2HP, only the bullet has no biult in ANT)

as for the bidirectional problem, I am not sure what you mean. you only have a couple hundred ft from one end of your install to the other. if you used 5 bullet 2HPs with omni ANT on them you will have plenty of signal. you wont need to repeat at all. the DSL location will pick up on the 4 bullets at the edges and connected to them automatically. they will also act as APs for your clients. I cant imagine that clients wont be able to pick up at least 1 of those 5 locations. how long are those buildings in the picture?

this is no lie, I connected to a bullet 2HP with a 8Dbi omni on it with laptop. the laptop has a 32mW radio in it (standard wifi card) we were 2 miles away. and I was able to surf at about 200kB ( not terrible fast, but we were 2 miles away! lol )

i like what you are thinking there. i have never tried the bullets with these antennas only with the pico's

i have some spare pico's but im hoping you will tell me to get the bullet m5's because they are more stable.

whats the main difference between a bullet m5 and a picostation 2 hp

(im hoping you will say that the m5s are rock solid?)

well the pico2 are a 2.4Ghz radio 802.11b/g

the M5 is a 5.8 Ghz radio 802.11a/n

totally different animal.

if you are wanting the "M" series of radio, the M2 is a 2.4 Ghz variety and will support 802.11b/g/n

this biggest difference with the "M" series is the ability to use the "airMAX" protocol that ubiquity came up with. they have a theoretical max of about 150 Mbs up and down. but you can't connect clients to them in this mode, it is for backhaul use only. you can use them in standard "n" mode too and get all the benefits of 802.11n

as for them being rock solid, they are a very nice radio, I have used both. but there is no stable release for open-mesh /robin as of now. they will use the robin2 firmware when that is fully released. you can use the beta firmware, but there are still bugs and I wouldn't use it on a system you plan to make money on Wink

Also the difference between 2.4 Ghz and 5.8 Ghz can be night and day depending what and where you deploy it. 5.8 is much more directional (IE: you need a better line of sight) 2.4 will punch through buildings better too. 5.8 can work better with longer distances, but takes less obstructions to get in the way before it doesn't work, lol. you really have to plan out what and where, then pick a radio to do the job.

sounds good. i am getting a quote for 5 of the bullet 2 hp's with 5 7 dbi omni directional (the big one we were talking about in another thread)

I will let you know how it goes. i imagine it will be awhile till i report back. thanks again Smile

good luck. I think you will find it is easier than you think to setup. the bullets are even more plug and play than the picos for outdoor installs.

i just saw this

is there a reason why i should get the non-hp over the hp. i know i have a crapload of ps2hp's that dont work very well from what i believe to be bad firmware.

antonio and i just created a test site with a few spare ps2hp's that i have so hopefully we will make some headway.

is the non-hp firmware more stable?

any other thoughts?

any firmware under r2692 is not stable with the bullet 2HP. if you are running r2692 or the r3xxx stuff then they will work fine.

ok cool thx.

i have an idea regarding your 15 dbi ANT solution we talked about in another thread.

Only registered users can see links on this forum!

as i said at opatb site i have pico station 2hp's with stock antenna.

i am considering replacing all of the stock ant's with some of the 15 dbi's.

my problem is that the manager is concerned about how they look and also how close they are to people being able to break or attack them (its a resort town with a high demographic of stupid high school kids).

my thinking is that the easiest and cheapest way to solve this (always the name of the game) is to run a small cable from my currently installed box and electrical outlet and mount the antenna directly beside it pointing down on all of the blue locations. the red line and x are another idea i had where i could bring the cable around to the side of the building and mount it there but i don't like the idea of getting a ladder up there etc. and i can really run a cable to the front middle of the building cus it will prolly look bad and be expensive.

my idea is that the ant's will be mounted next tot he boxes and i will cable tie them in about 3-4 places so that they cannont be "messed with"

does this sound like it may help from a signal/service perspective?

the 15DBi ANT we have are truly 4 ft long. mounting them with cable ties would prolly work, but you really want to mount them with a pole and pole mount kit. mounting them on the edge of the roof pointing up will certainly keep people from messing with them.

the idea is that if its upside down it will give signal to the building itself. or at least that is my theory.

does it matter if its upside down or not (the 15 dbi ant) or will it go below as well as above.

that would work, just make sure that the bulk of the weight is not on the connector. you will see if you get one of these. they have a nice metal area to put a pole mount.

also, dont forget to use mastic tape on the connector if you are gonna mount it upsidedown. dont want water getting in your connection. Razz


nope, doesn't matter. as long as you dont get a downtilt ANT, then ofcourse, mounting it upsidedown would tilt the signal up into the sky, lol.
