3.3Ghz - 3.5Ghz is a ham allocation, so why compete with the 2.4ghz?

Nothing like spectrum with a low noise floor!

Yeah, but there's nothing like getting "stuck" with using equipment from only one manufacturer with limited availability, is there??? :-) |

I have a pair of the Ubiquiti 3.3 GHz modems with their Router Board Pros which I am currently "playing with" as a backhaul transmission system for my mobile communications unit.
There is another vendor "Xagyl", but I don't know if they are compatible.
If I can get any kind of decent range/throughput with them, I'm planning on purchasing several more. It would be nice if hsmm-mesh software would support the RB Pro, as it supports three mini-PCI modems. I also have a couple of the 900 MHz modems, but the spectrum around here is pretty badly polluted in the 33cm band (who is using these pagers these days anyway? :-).

I have a router board and modular radios. We will move to other bands at some point. We have limited help and we are working to port the HSMM-MESH firmware to other hardware platforms. There is a lot of interest. We will let everyone know when the hardware base is expanded.

I am, in fact, using RouterBoard Pros. I was a little concerned about having more than one power-over-Ethernet voltage "running around" in my communications truck, so I standardized on the IEEE standard. Just to make certain, I use only purple patch cords for POE Ethernet connections!

Going the router board way is very nice, but I have found out that others will not go to the expense of that type of system. ( I priced it out once, with box, 2 cards, board was around $400 ) It is more fun if others will play too! That is why the Rocket / Nano series is attractive, since it is mass produced for other countries, we can take advantage of the low price. If the Nano 3 can become a access point/mesh node as well using the DD-WRT software then more people will join in. No need to by the high power rocket base station. aka Meraki networks.
What would be nice is it working with the DD-WRT software and the Mesh component. Looks like that would cost $25. ( If I am reading the website correctly.)

Unfortunately, the ubiquiti nanostation 3 is not available (or legal) for sale in the US. It is an export item. Of course, a foreign ham could always use it.
Ubiquiti has several 3GHz products (XR3 mini PCI card: $200; rocket M3: $190; nanostation M3: $170), but as you can see, the price to play is higher than $25. ;) |

Yes..I was thinking about the M3 or the Rocket M3. The price is better than just the card and it is plug and play. |

Unfortunately, both devices are manufactured using Unobtainium.

Check out 3.65GHZ.

Licensed lite. Pretty cool stuff. |

3.65 GHz is a complete disaster around the Dallas and other metro areas because of the company TowerStream. I run a Wireless ISP in NE Collin county (hence my call) and have had a nation-wide 3.65 license for several years now (WQJI711.) However, since TowerStream (another WISP, though nation-wide) purchased the grandfathered earthstations so they could have exclusive rights to 3.65 within the 150km exclusion zones.
Any of the Ubiquiti (or other manufacturer) equipment on the lower 3 GHz bands are manufactured ONLY for export (out of the US) usage since there is no spectrum availability domestically except ham use, so they will be in very scarce supply. |

My understanding is that you could swap crystals in the WRT54G router to make them work on other freq, Does anyone have a guide on doing this with a parts list? I am interested in setting up an HSMM Mesh on Freq dedicated for Ham Radio |
