Will elevation effect performance

[Tizzle128]

Hey everyone,

 

Cant seem to find this online, so i figured id ask here.

 

I recently bought a house and im in the process of using Gliffy to layout how my network will be. The plan is to have my router on a shelf above my desk. So my question is this, will having the router closer to the ceiling effect performance vs say table height?

 

If it matters my router is the Asus TM-AC1900. I can provide the Gliffy layout if needed to but im still working on it.

It is harder for a wifi signal to go down then it is up.

[Levent]

nope.

Depends on how you place the antenna.

[MatthewEnderle]

2.4GHz and 5GHz RF waves will reverb inside your room along with passing through walls. you will be fine presuming you are using an omni-directional antenna.

So im using the default Asus antenna's currently, is there a specific way to arrange the antenna's that would be best, This shelf will sit at the dead center of the house by the way.

Afaik it should sit horizontally facing towards the devices that need wifi or in the general direction of those devices.

But I'm not 100% sure about that. MatthewEnderle seems to know more about that.

[MblaZe7run]

Theoretically, yes. Realistically, no.

[Tizzle128]

My Overall thoughts were since there are 3 Antenna's have one in the standard vertical position and 1 facing towards front of the house and 1 towards rear.

The way you place the antenna should be in the direction that will broadcast to the otherone the best. A standard RP-SMA antenna will emit like this diagram below.

The diagram shows the antenna in the vertical orientation or like this."(( | ))" You should notice that there is an area at the top where it is not going to be emiting. That is called the Cone of science. Also this doesn't mean that you won't get any signal at all above or bellow, the signal strength will be reduced.

 

Here is a much better image.

Thank you very much for this diagram, networking and radio waves are way out of my area of expertise(which is almost none) if i am understanding correctly, For optimal signal strength you would want the center of the antenna to be at the level of usage for the devices connecting?

Yes you want it at the average level. Honestly ±5ft won't really make a huge difference. it's more about stories. Since I've studied Radio communication and RF/IF systems I'm going to be redoing my parents networking in their house. I already condensed the network from this

 

On our farm silo outside

ISP-> wireless moden -> router-> hi-gain antenna-> 

In the house

hi-gain antenna->linksys bridge WET54G-> linksys router WRT160NL->PC

At the Neighbor's house, we give him internet for farm land.

hi-gain antenna->linksys bridge WET54G-> linksys router WRT160NL->PC

 

To this

 

 

On our house

ISP-> wireless moden -> router (Serves upper story's wifi-> POE antenna-> 

In the house

POE antenna> linksys router WRT160NL(main floor wifi)->PC

Neighbor's

 POE antenna> linksys router WRT160NL->Pc

 

Essentially I removed two old antenna's ($200) with new POE antennas and the new antenna will also transmit the 1.5mile range and also allowed me to remove the two supper-old, often-crashing, crappy linksys wireless g bridges. One wireless N one would have been $300+ per device. Not even AC standard.

Luckily we have a perfect rectangle single floor house, total about 1200 sq feet, the shelf will be approximately 5 feet off the ground and in the dead center, i plan to use powerlines for most of the communication (pic attached) but we do have laptops and cells that will be using the wireless signal typcially around the 3-4 ft height from the ground to normal usage area.

Then you should be fine.
