Re: WISP equipment to penetrate houses in 2km range
i already make a survey. there about 40 to 60 house who would like to subscribe due to no broadband internet connection available in the area. im planning to put up WISP in that area. all of the houses are in concrete type of walls and about 20 house are behind trees but the rest are at line-of-sight. what are the equipment used to penetrate trees and concrete walls? |

Leander, TX | I really doubt that you will penetrate the trees in the Philipines. I know you won't be penetrating many concrete walls. You really need a good line of site and mounting your equipment outside to eliminate the walls. |

These are used in the U.S. to penetrate trees and concrete walls...

| Appreciate the reply...
Forgive the ignorance, how can these dfferent frequencies work togather.. Can you suggest any equipement types that are needed?
Second low poer APs I am assuming you mean lower frequency, like 900MHz?
Does the lower frequency => less distance ?
I am assuming that a wireless ISP should probably use a 5.8Ghz backhaul. The transmission to a house with line of sigh can be 2.4Ghz but to a building or a covered area would need to be something for the 900MHz range ?
Hope it is not too much and thanks in advance.

1. When he says work together I assume that he meant that they can work at the same time without interfering with one another.
2. Low power AP's don't mean less frequency, you can adjust the power to effectively change the range that an AP has.
3. I explained this in another post so this is a copy, and the answer is: It depends on your location.
The 900 MHz spectrum has a larger fresnel zone than 2.4 GHz, and 2.4 GHz has a larger fresnel zone than 5.8 GHz, meaning that to go a greater distance 2.4 GHz would go farther than 900 MHz, and 5.8 GHz would go farther than 2.4 GHz. All this is given the ground is flat and there are no obstructions, and the CPE and AP's are exactly the same height. A large fresnel zone will contact the ground and other obstructions. A lower frequency will contact these obstructions before the higher frequencies will. Now having said that. If there are trees and obstructions, then 900 MHz can "pass" through this type of interference better than 2.4 GHz, and 2.4 GHz can "pass through this type of interference better than 2.4 GHz. So to answer your question. It depends, but I hope this gives you a better understanding of what spectrum you will want to use. Typically 2.4 GHz and 5.8 GHz are you LOS solutions, and 900 MHz is your NLOS solution. |

| Dude..
This is great information, I am really thakfull. So how can you connect all these frequencies togather? Do you need a specific device of some sort ? I mean if, I use a 900MHz signal to connect a sight but my backhaul is 5.8Ghz or 2.4Ghz then I would need a mediume in between right ? If so what is it? Where can I find it?

1 edit | I'm believe that you would need a couple ethernet cables and a bridge of some sort. I've personally not done this, so don't take my word for it. |
