Wireless Access

i have an outdor Covarage request , we will use  AP-175  

issues is that some location have very high density that can reach 200  Users ,  i was thinking to put multiple APs at those locations each to work on certain Channel 

is it better to use  "ANT-2x2-5005"  or "ANT-2x2-2005 "  in this Case ... target is user Coverage , each AP will have ethermnet cable for BackHauling ...

Thoese are two different antennas using different spectrums.

• If u using to give access to your clients via 2.4Ghz use the 2x2-2005 | if u planning to give access to your clients via 5Ghz use 2x2-5005

.(check your client types)

• its' better to use 2.4Ghz in order to get higher coverage. But the 5Ghz spectrum is with less interference and lower noise level (even in outdoor deployment)

• you should do a small active site survey in order to check the coverage you are getting from different location with different antennas types and different spectrum use.

and for Antenna Types , when to choose one with angle Zero ( Omni ) & when to choos eone with angle 30 or 60 ?

Telnet - 1,

The important thing to focus on in outdoor networks is that the signal travels  a long way, even for omnidirectional antennas.  One key to choosing an antenna for client coverage is determining the size and shape of the area that you have to cover, as well as where the access point will be mounted.  Outdoor networks have many more things to consider and we would not be able to give all of the answers here to provide you the best solution. 

The Outdoor Mimo Networks VRD here:  http://www.arubanetworks.com/wp-content/uploads/OMWN_VRD_2012-01-04-1.pdf goes into a great amount of detail on outdoor strategy.  It also allows you to ask alot of the questions that we would not be able to here.

telnet-1,

You should also check out the High Density WLANs for Auditoriums Reference Design Guide.  

http://www.arubanetworks.com/wp-content/uploads/dg_highdensity_vrd.pdf

This includes design rules for any high density area, we just picked auditoriums because they are easy to understand.  But the basic ideas presented apply to everything from a classroom up to a football stadium. 

You should plan on 50 users per radio.  With a 50/50 split of 2.4GHz and 5GHz clients, that means 1 AP can serve 100 simultaneous users.

So you'd need 2 dual bands APs  (e..g 4 radios) to handle 200 devices.

Hi,

I am on a project and planning an outdoor solution for a customer. I am going to use outdoor AP 275 to cover a large area. Does anybody can tell me; for open area, how many meters ahead can signal be in range without disconnection?

Thanks.

emirate.ay,

What will your user density be in this environment?

What kinds of devices and applications do you plan to support?

The signal from an AP275 can carry a good distance, but the number of users and the application you need to deliver will determine how close you would deploy AP275s for performance.

I dont have any information about the density, but the project is an municipality project for a square. So I guess per unit it will be max 50 users. Mostly people use "social media, whatsapp,...etc."

is AP-275 can support through almost 100 meters?

Yes it can.  You need to ensure that there are no obstructions and all of your clients have good radio line of sight and the space is very open.  Users could connect at 100 meters, but as more users connect, they share the signal and it reduces throughput.  There is also a much greater chance for site-specific interference to reduce throughput, as well.  Every environment is different, so you should make an effort to obtain one first and test in that specific environment to ensure that it will meet your need at those distances and at that height... Methodology for deploying outdoor Mimo networks is detailed in the outdoor MIMO VRD here:  http://www.arubanetworks.com/wp-content/uploads/OMWN_VRD_2012-01-04-1.pdf

I would at least take a look at the VRD to understand how to get the best performance for 802.11n and by extension 802.11ac outdoors.

Thank you for clear information.

have a nice day.
