| Who's using 80GHz Does anyone have any experience with 80GHz ptp?
Who would you consider to be the best?
What are you using and how is it working in heavy rain?
How long are your links?
GigaBeam
E-Band
BridgeWave

kudos:1 | We don't have any in our network. But we have installed Bridgewave links. They include an aiming tool that seems to just get in the way. They say you're supposed to get the training before installing the units(we didn't:)). Their interface is very simple and straight forward, the manual is very small and clear. You have the option to check the signal level via a browser or voltmeter--do it with the voltmeter, it's much more dynamic and responsive than the browser. The links were installed in a middle of the road climate(no excessive rain/temperatures). The first link was installed over a year ago and the customer hasn't called for anything, so I'll assume it's working OK(no news is good news:)). |

I was told by someone that 80ghz could do 7 miles. Can't remember the brand but they said it was a 1Gbps system but at 7 miles would still do 100 Megs. Seems too good to be true. Where I am it doesn't rain much but still. Is there any truth to that? |

I can't remember the limit, but 7 miles sounds very optimistic. |

Doubt that....

I don't think 80GHz will hold up in a heavy rain over a mile, not at 1000mbps. |

I've seen guys run it at 8 miles in desert cities but when the rain comes, say goodbye. In the midwest, I spec Bridgewave at 3 miles with the smaller antennas and 4 miles with the larger antennas as long as I have adaptive rate. If not, I reduce both of those by a mile. |

Agreed, I think a lot of people post replies based on the manufactures marketing hype.
I don't understand some people. If you need 100mbps, 310mbps or 1000mbps to meet the networks demand than you can't have the link dropping to half the required speed every time it rains. It only make sense that when it's raining more people will use the internet.
I just think we should be building 5 nines networks so we don't have people thinking wireless doesn't work in the rain. |

Unfortunately it's always a balance. If you are going to drop rate 1% of the time but you get to save the cost of an additional relay link, it might make sense. |

Are these numbers with LOS or no? |
|
| Not that Ive ever used 80ghz, but Im certain it requires LOS.
80ghz=3.75mm full wavelength. heh.

It has trouble going through glass so yes 80GHz is only LOS. |

LOS only and veeeeery narrow beam! |

It is like any other microwave system, other than Orthagon. It requires RF line of sight in order to operate properly. |

Using BridgeWave 60Ghz for 2 years now...very short distance (a little over 1/4 mile) connecting 2 buildings, solid, iperf tests show above 900Mbits in full duplex. Well worth the price the company paid. |
|
| I have the E-Band radios, hoping to have them installed by the end of the week. |
|
| Love the RedBull product placement 
What's the cost ? What's the throughput ? |
|
| I can't say anything about the pricing.
The units are 1000Mbps Full Duplex.
I'll let you know the real world speed when I have them installed. The link is less than a half mile. |

LOS only. IIRC 60GHz and above are affected even by oxygen molecules, so I doubt you'll get any form of NLOS out of these things... |
|
| REALLY! I can't understand why people keep saying that. 5.8GHz and even 2.4GHz blows at NLOS. Sure we've all been doing it for years but I haven't in years and will never install anything I can't get a clear shot to.
Ok, thats not totally true. All the indoor hotspot APs are NLOS. |
