| 8 mile NLOS link
Hi, I need to create an 8 mile or so link that delivers reasonable speeds (1.5MB both way's fine). I don't have a very large budget, and need the antennas to be unlicensed. What would you guys suggest? I found this site: »www.dailywireless.org/modules.ph···sid=4100 that said "Vyyo's Non-Line-of-Sight 700 Mhz modem, the V284 provides coverage more than 9 miles NLOS outdoors." But I haven't really found much information about it... So I guess it's possible to have a NLOS link of 8 miles, but I really don't know much about wireless and thought it might be wise to ask people that did for some advice 
Thanks,
Nathan |

Leander, TX | Is your link NLOS because of trees, buildings or a mountain in the way? |

Thanks for the quick reply, I live in Indiana, so There are large patches of trees at the end of each field. There might be a few building in the way, but I think it's mostly trees. |

1 edit | Nathan, you could be seriously mis-led if you start searching for NLOS equipment before path analysis using Radio Mobile.
Kindly place your mouse on each of end of the link in Google Earth and post the co-ordinates shown and WISP folks will check the path for you. You should also check the buildings and forest along the path visually.
Vyyo CPE uses a DOCSIS (cable) modem with a 700Mhz upconverter, but the article forgot to mention you need to spend $100K on the base-station radio and CMTS head-end.

1 edit | Nathan, I recall suggesting multi-hop from Huntington »Advice?
You risk spending $10K or more to find out high-speed NLOS may not work for you because there are some points along path that are ~20ft higher with forests.
If you really want to try and have ~$1000 to spend, buy a pair of 900Mhz/18dBi grids and 900Mhz/1W Maxtend RS232 modems.
Install as high as you can - I will suggest 60ft minimum. If the link does not work, you can sell them as two 900Mhz spectrum analyzer kits at a profit.  |

There are two vendors. One us, one in canada.
Yagis tend to work better at 900 MHz. |

I hope you appreciate this I spent the last hour trying to get both links on the map but they are too far apart so this distance my be closer to 5 miles..
Your going to need AT least 60Ft towers on each end for 900Mhz

[lutful] Yep, that was me in the other thread... I've been away and forgot all my login information though.[/lutful] I found a WISP that has an access point at the other end of the coordinates I posted, they're like 7.83 miles from me. When I called them to see if I could get their internet they said their equipment was 900 MHz and they only served people within a 5 mile radious(I'm cursed) of an access point. So I've been trying to find some sort of 900 MHz antenna that they would let me use... |

I am using 900mhz Avalan Wireless radios with 15db yagi and they are working great, the link is 9.4 miles and you have a better path than I do. I have 160 tower with equipment mounted @ 130' level on one side and a 35 foot tower on the other. The 900mhz will penetrate tree but not mountains. Good luck with your link.

Before you start looking for an antenna you need more info. All 900 MHz gear does not work together, so the first thing you need to find out is the brand of equipment the WISP uses. Then you also need to know what antenna the WISP is using on their tower as well as it's height. |

The antenna is located on a grain leg, it's probably 60-70 feet high, although I'm not sure... The WISP's office is closed on Saturday and Sunday, so I won't be able to get the information until monday. Would the antenna on my end have to be very high? The land here dips here, but there aren’t any mountains or anything... The roof of my house is about 35ft high, I don't know if that would be high enough though. |

40 56 39.87 N , 85 26 22.87 W, is the wireless ISP's access point. 40 58 02.08 N, 85 35 12.52 W, is my house. I still haven't gotten in touch with the ISP's office, so I don't know what brand of equipment they're using, but I'm hoping to call them today. |

What is the name of the provider? You can IM me with it, if you don't want to post it. That is fine by me. |

I called them again today but to no avail. I keep getting customer service people who have no idea about anything! The last customer service woman I talked to said that someone who knew what they were talking about (not her exact words) would call me back. So I'm still waiting on that call... |

The brand they use is "Motorola Canopy". I can't get the towers height, but it's probably somewhere around 70'. |

Ottawa, ON | Please ask your WISP to do a site survey using connectorized SM and a few high gain antenna choices. |
