Re: 15 Miles shot. How to do it?
How´re you doing John. I´m glad to hear from you. I´m trying to survive downhere. As you see, I´m thinking deliberant instead of d-link now. That´s a big step for me as you already know.
Ok guys, thank you all. Sorry for leaving you alone discussing this subject all this time.
said by John Galt  :said by LLigetfa :I think you are interpreting part 15 different than I do. Part 15 does not apply to Anoclon... John is completely right. He knows my entire story and FCC and part 15 regulations does not apply to me. So please, in my case forget about any rules you have upthere in US. I could use any radio with any antenna I want, with the output power I want but I´d like to keep it the cheapest possible way. In this case, I´ve considered deliberant.
I want it to be a PtP link, from any of my bases, to the client. My question is: do you think deliberant would do the job? Would the throughput be enough? What model would be best?
What´s the difference between a connectorized and a NOT connectorized radio? |

| 1. I have read / learned on this forum that a 12 mile link would be the maximum distance or limit on a wireless connection without having to re-transmit the signal. Am I wrong or understood wrong?
2. Have you checked with google earth the surrounding area for client side? there´s a lot of water (canal / river) between the bases and the client. Could that affect the signal? |

| 1. The 12 mile limit comes from "deafult" timeout value for packet acknowledgement (ACK) - many firmware lets you increase the ACK timeout value for longer links.
2. Many of our links go over water at low height. Do not worry about that.
If you use connectorized DLB2300, please try 24dBi grid antenna since you could lose a few dB signal due to less-than-perfect tightening of cable and other strange issues. |

I have a 13 mile link that does 7.5mbps.
The tower side has a 24dbi panel that I'm going to change to a 27 or 29bdi grid and the client side has a 29dbi grid.
Both sides are running SR5s in Router Board 532s.
I'm setting up a test link that's 35 miles. I have my side setup with a 24dbi grid and a SR2 in a RB532 and the other Wisp is setting up the same on his side.
At this point he has a 15dbi omni with a CM9 in a wrap or RB532 and I can connect to it with a -85db signal so I think the link will be good with the new hardware on his side. |

| You could try a pair of radios with integrated panels but if they don't have enough power to give you the fade margin, you will have to shelve them.
If integrated panels don't work out, go for connectorized and get as much antenna gain as you can afford to buy and that the weather there won't tear apart. Then, since you are not bound by part 15, you can adjust radio power to give you the fade margin you need.
Good antenna gain always trumps radio power since it works both ways. |

If I were you and I could spend the extra money on this project, I would use the following equipment.
RB532-4A RB532 64MB RAM, Lvl 4 lic $185.00x2=$370.00
DCE-CaseKitPGME Die Cast Aluminum Case PGME $32.30x2=$64.60
SR2-80211bg SuperRange2 802.11b/g 400 mW mini-PCI $109.95 x2=$219.90
Ufl6-NFB-.5 Pigtail Ufl6 to NFB 5" $13.00x2=$26.00
POE-48 48v Input POE Injector $22.45x2=44.90
NM-NM-400-6 Pigtail NM to NM LMR400 Style, 6 ft $16.30x2= $32.60
DC24-HD-PF1PF 2.4GHz 24dBi Die Cast Antenna N-Female $58.45x2=$116.90
Total: $874.90
But I would also use 5.8Ghz not 2.4Ghz. The cost would be almost the same.

| Well... there are still too many unknowns to make an accurate assessment. We know nothing about the two bases or the seaside site, noise floor, spectrum use, tower heights, wind factor, etc. There has been little described of the seaside location as to the immediate terrain and what sort of tower can suitably and affordably be erected.
5.8GHz has more free space loss than 2.4GHz. That said, there is the osbridge 5GXi with integrated 23dB panels (10 watt EIRP) at $200.US that could be considered. Wind loading would be minimal on an integrated panel. They also have a connectorized version one could use grids with for more $$$ but wind loading would require more substantial mounting. |

PersComp, can you do a calculation using the DLB-2700 and 24 dB grids?

Thanks...and back to vacationing.

The 23XX means that the base radio is a DLB2300 module (with the same firmware) and the XX19 means that it has the 19 dB panel antenna.
