RE: Aruba/Alcatel AP70 Remote AP maximum throughput

[Osborne, Bruce W]

I have not used AP-70 as a Remote AP much.

Just a reminder, the last sale date for AP-70 is May 31 2011. Aruba recommends 
they can be replaced with AP-105, AP-124, or AP-125. If you need USB in a 
Remote AP environment, RAP-5 or RAP-5WN may be options as well.

We have a couple of battery powered RAP-5s using USB cellular modem as a 
backhaul to our controllers. They work quite well.

Subject: Aruba/Alcatel AP70 Remote AP maximum throughput

I've been doing some testing of an AP70 AP as a Remote AP to investigate poor 
throughput.  What I've found through my testing is that two different AP70's 
seem to max out at 4Mbps as a RAP (haven't tested as a local AP yet).  AP125's 
seem to max out at line rate (same configuration for both AP's).  Anyone else 
see this type of behavior with the AP70's?

Re: [WIRELESS-LAN] Aruba/Alcatel AP70 Remote AP maximum throughput

[Steve Hess]

Got confirmation from Aruba that the AP70 maxes out around 5mbps as a 
RAP because encryption is done in software rather than hardware (like it 
is with the AP-125's).  Thanks for the heads-up on end-of-sale.  The 
only AP70 I have was being used as a RAP (because of the extra port for 
switch uplinking) but given the performance limitations they're of no 
use to me. 





Thanks,

Steve

Wireless Planning

[Lay, Daniel]

I am working on a plan for wireless in one of our libraries.  So far I cannot 
find an assumed standard for Db loss from bookshelves filled with books. Now 
granted that various configurations will have varied path loss, has anyone 
arrived at an average number to use in planning situations?

RE: Wireless Planning

If your libraries are anything like ours, I wouldn't get overly hung up on 
bookshelves as permanent objects- we se frequent rearranging.  A bit denser 
deployment is worth it to not have to redesign everytime shelves move.

Re: [WIRELESS-LAN] Wireless Planning

[Methven, Peter J]

Daniel, I would second what Lee said. I got a bit worried a few years ago on 
what the metal book shelves, full of books would do to 802.11g/ 802.11a and 
drew up plans with this in mind, including doing some db loss tests etc, before 
I realised the capacity requirements were far more important.  Also a month 
after all the APs were installed the library redesigned one of the 4 Floors. A 
year later another floor, and a couple of months ago a third floor! 
If your library is like ours for usage numbers, you will want to plan for 
capacity, rather than coverage so you'll be adjusting strengths downward (for 
2.4 Ghz anyway) to ensure you don't have excessive overlapping "cells" but to 
ensure you can provide enough capacity for all the multitude of devices.
Many Thanks
Peter

I agree with others that density is important.  While we believe the 
wireless in our main library has good coverage, we are in the process of 
adding some additional access points in some areas for performance reasons.


As a hedge, in some areas you may want to consider running two cables to 
each access point and leaving 30' of slack at each AP.  You could then 
easily deploy more access points in the future if needed.

Our library deployment was tons of fun as well. I concur with the 
others, go for density and have a good overlap. Beyond that there are 
too many variables and you will go crazy trying to make it "perfect."
