Line of sight requirements

[bartv]

Hi,

I am looking to link my business to my home (4.9km according to google earth). There are two hills along that path, and I live in a treed area.

Is the PowerStation able to deal with this type of problem, or should I look for a different solution? If so, any thoughts on how to get a high speed link without line of sight in a rural area?

Thanks, Bart.

Can you PM me the GPS numbers and let me take a look. The trees may or not be an issue. But if you don't have a clear line of sight, no 2.4 Gig products will effectively work, regardless who makes them. You may have to use 900 MHz gear.

Oh no...that hill across the road from you to the west is 45 feet or so above you. That won't even qualify as a non-line of sight. No wireless will work.

Darn. What would qualify for a non line of sight system? If I can place a repeater somewhere on a hill, could that solve the problem?

Thanks for looking,
Bart.

Hello Bartv,

A repeater on the hill, that you could see from both sides would alleviate the problem.

Thanks,

Non LOS would be like a grazing path or light trees or gently rolling hills, but you're on the back side of a "mountain"...but...there IS a house on the top of it, but I can't tell where the driveway is. It doesn't appear to be an isolated barn as I can see a chimney on the west side. Offer them free internet in exchange for a four foot tall piece of white PVC on their chimney...use 12 Meg WDS and you'll get a 6 Meg connection at yer place.

WHT, based on recent information that has come to my attention, I hear you are testing a sub-space nanostation that can go through mountains. Fess UP!!!!

Yea, but be careful with the TX-power on that model, or it'll create an anomaly that pulls you 40 years into the past!


Grtz,

Whutchoo looking at ME for???

Cause you have the Jimmy Newton lab with secret mesh technology.

[WHT]

Nope...I use MTV's "Pimp My Car" labs.

From my understanding of the terms:

LOS - Line of Sight: Path between two sites clear and free of any obstructions and the Fresnel zone is free of obstructions.

nLOS - Near Line of Sight - Visual path between two sites is clear but there are some intrusions into the Fresnel zone.

NLOS - Non Line of Sight - Obstructions in the visual los path.

[WHT]

There's no strict definition of the terms, but generally (in radio work)...

Line of sight implies you can see the far end and have sufficient Fresnel zone clearance as well.

Near line of sight implies you cannot see the far end and have significant (50% or more) terrain or building incursion into the first Fresnel zone.

Non line of sight means you will only get a subfraction type of diffraction to the far end. By that logic, you would think the shorter wavelengths at 5.8 Gig would bend over a hill better than 900 Meg (and 5.8 does bend better), but in such an over the horizon shot, you're going to have a lot of trees, etc. that will block 5.8, but pass 900.
