Let’s say your an ISP deploying Wifi in a High-Rise Building. 300 Units, 25 Floors, 12 Units Per Floor. You decide to deploy 2 APs per floor using . Realistically if all 300 units used the wifi, you would have 6 units using 1 AP.
If you used a MT 411 and Wireless N card in the 20Mhz spectrum, what is the max bandwidth you would offer per unit that can realistically be achieved?
If you used the same thing as #1, but in the 40 Mhz spectrum would you deploy only one per floor or two?
Depending on 2, what is the max bandwidth you would offer per unit that can realistically be achieved?
Personally, I can never achieve over 30mbps of actual throughput on my laptop and it has a decent wifi card (Intel 4965AGN), but what if somebody wanted 40mbps or 80 mbps? What is realistic and what is not?
Looking for insight since these are the exact issues we face when competing against the ISP giants that offer 100mbps connections that are completely useless to people, but people don’t know they can easily survive on 3mbps. Thanks.
I have a 411AR w/R52n running wireless for my home right now.
I get around 60-70mbps dual chain 20MHz channel. I max out my ethernet with a 40MHz channel.
Throughput is not very consistent. I hit the 100Mb ethernet limit downloading from a local webserver, but when playing videos over the network (hosted on a desktop, playing on my laptop) it stutters on videos with high data rate. Nero will not buffer properly on my laptop if burning a file hosted on the desktop.
File transfers will run around 50-70Mbps full duplex. I think my switch may be the limiting factor there.
How does that make sense that you can receive 60-70mbps throughput, but your laptop stutters with video. Is that actual throughput or the data rate your laptop connects to the wifi?
If you had even 10mbps of actual throughput of wifi, you wouldn’t have videos stutter even when viewing a 1080p video on the laptop assuming the 10mbps is consistent and your laptop doesn’t have video processing issues.
Could you please describe a little your infrastructure? What switch do you use? Which router? Where is located AP?
How did you calculated bandwidth?
I wonder since I am thinking to get RB435G with R52n to use it as AP. Cause my current AP is RB751U and wi-fi performance is suck.. 10/7 Mbps if to believe Speedtest.net

Looking to see somebody weigh in on my original question rather than other questions coming up. Let me know if you have any insight. Thanks.
As far as I can tell Windows uses 802.11n multiple streams more effectively than Media Player Classic. I can download just fine, copy files back and forth without issue, saturate my LAN. Most of the time it will not play back high bandwidth video properly. This did tick me off just a bit. Testing after upgrading to 5.20 seems to be working better. Just checked and MPC has updated as well, that may have made the difference.
Nero will not burn a disc worth a crap over the network, even after 5.20. It will pull less than 30mb. I can watch the traffic, it will double easily if I access network files, but Nero will not pull. Same program on the same laptop works fine over LAN.
20MHz, dual chain, I can download at around 7 MegaBytes (BIG M, BIG B) per second. I can copy files over Windows shares at around 60Mbps, around 6MBps. The web server is in the next room. The file server/DVR is in the same room. I am less than 10 ft from the AP. Signal is in the mid -50s.
Vadyalex, I’ve found speedtest.net to be particularly unreliable, at least over wireless. Speakeasy is closer to the mark for us, but using torch while doing the test has made me wonder where they get their numbers. Go download SP3 for XP or something. Speedtest will show me at ~2Mb, then I’ll download an update/driver/etc and pull the full 10Mb of my fiber.
RB411AR + R52n, dual chain, 40MHz, 5GHz. It is just a straight bridged AP, no routing, no QoS rules, CPU limit slows down local transfer, isn’t really needed with only one client. QoS is handled at my router.
A little more specific to your original question, how big are the floors? Width? How many rooms? Internal walls?
Depending on the layout you’ll likely need more than two AP’s at 5GHz and you won’t get much throughput with 40MHz on 2.4GHz.
The Intel wifi cards are my benchmark in the fact that everyone has one, so if the hotels I manage wireless for are going to work, they have to work with Intel. Broadcom and Atheros wipe the floor with Intel cards. I keep a few around just to use for site surveys. If my Atheros works, Intel might not. If Intel works, 99% of the wireless devices out there will do fine.
