Data rate supported by 6533

Hello,
Can someone tell me what is the data rate supported by PCI 6533. i mean transfer the data from peripheral to the hard disk of the PC.

Hi,
Here are a couple Knowledge Bases that address this performance specification. I just posted the knowledge bases today so they might take a day or so before they are live. Hope that helps. Have a good day.

WLC Data Rates behaviour

Hello everyone!
I have some questions about the data rates configuration in WLC. I've been reading Cisco documentation and this forum, but as I've seen some contradictory information I would like you to clarify me some points.
I want to disable 802.11b clients, so for that I'm going to disable 1, 2, 5.5 and 11Mbps data rates (other option could be set these as supported only). Then, I have to assign at least one of the other data rates as mandatory...
I could think in one of these three options
Option 1: all 802.11g data rates as mandatory. In this case, as far as I understand:
Broadcast are sent to the lowest data rate
Multicast are sent to the highest data rate (but if a client is connected to other data rate than the highest, then multicast frames are sent to this data rate supported by the client, is that right??). Basically, you cannot be sure at which data rate multicast frames are sent as it can change depending on the clients.
Clients can connect as soon as they support one of the mandatory data rate
Option 2: one 802.11g data rate as mandatory. This would define better the cell limits.
Broadcast and multicast are sent at the same data rate
Clients can connect if they support the mandatory data rate
Option 3: set two data rates as mandatory (or the OFDM required data rates: 6,12, 24Mbps), and the others as supported
Broadcast are sent at the lowest data rate
Multicast are sent at the highest data rate (shifting back to the lowest if a customer cannot connect to this data rate)
Clients can connect if they support at least one of the mandatory data rates.
Am I right with this assumptions? I have read some other different behaviors, like broadcast and multicast are sent at the same common data rate...
I hope I have explained myself...
Thank you very much for your support.
Carolina

Hello,
thank you Scott and George!
I read the post, and it is ok, and I finally have found some information in Cisco's website:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01011.html#ID2482
"Access points running recent Cisco IOS versions transmit multicast frames at the highest configured basic rate and management frames at the lowest basic mandatory rates, can cause reliability problems. Access points running LWAPP or autonomous Cisco IOS should transmit multicast and management frames at the lowest configured basic rate. Such behavior is necessary to provide good coverage at the cell's edge, especially for unacknowledged multicast transmissions where multicast wireless transmissions might fail to be received. Because multicast frames are not retransmitted at the MAC layer, clients at the edge of the cell might fail to receive them successfully. If reliable reception is a goal, multicast frames should be transmitted at a low data rate. If support for high data rate multicast frames is required, it might be useful to shrink the cell size and disable all lower data rates.
Depending on your requirements, you can take the following actions:
If you need to transmit multicast data with the greatest reliability and if there is no need for great multicast bandwidth, then configure a single basic rate, that is low enough to reach the edges of the wireless cells.
If you need to transmit multicast data at a certain data rate in order to achieve a certain throughput, you can configure that rate as the highest basic rate. You can also set a lower basic rate for coverage of nonmulticast clients."
Based on your experience, does it have any sense to have configured all datarates as mandatory? This is the current configuration I have in our controllers but it wasn't done by me.
Thanks.

Max Data Rate: AGP 2x?!

Bought myself a new MSI-KT6 Delta a few weeks ago (MSI-6590), and have had no problems until now.
First up, my GeForce 4 Ti 4600 decided to suddenly die. Random characters on the screen in text mode, flickery colours and corrupt pixels everywhere. Windows wouldn't detect it properly anymore.
Bought a new Powercolor Radeon 9600 XT with VIVO today. Downloaded the new drivers, and loaded up some Battlefield, all good. Runs nice and smooth. COD, Quake 3, etc, no problems at all.
Halo, however... BAD. Even with the basic graphics settings and no Pixel-Shading, it runs at 4 frames a second, and nothing I do changes this, from lowest to highest with Pixel-Shaders 2.0. Although there's a visual difference, it's just as slow.
So I loaded up ATI control Panel and used SmartGart to enable 8x and Fast-Writes... Rebooted, lots of flickering screen, and Windows XP is now software-rendering everything (Transparent menus take 100% CPU to fade in)
Wait for SmartGart to fix my graphics again, and it's all back to 4x and no fast-write.
Loaded up SiSoft Sandra, to check the settings in there...
Mainboard: "Max Data Rate: AGP 2x"
AGP Card: "Data Transfer Modes Support: 1x, 2x"
"AGP Bus is unused or AGP card not fully AGP compatible"
Er... should this be right? BIOS wont let me select an AGP speed, it's "Auto" and I can't select it. I'm a little concerned that my Motherboard may have been damaged! I'll go get the latest Halo Patch, but it doesn't change the fact that I can't use 8x or Fast-Write.
I'm a little apprehensive about flashing my BIOS, made more difficult by the fact that I have no working floppy drive.
CPU: AMD 2600+
RAM: 2x512mb DDR 333MHz Kingston
AlphaGremlin

Well, I updated the VIA drivers, and an updated Sandra. AGP is running at 8x, and Fast-Writes are enabled! I don't know what the hell SmartGart was going on about, but it appears to slunk away and disappeared completely from the ATI control panel since the last reinstall of drivers.
So there's one problem solved... but I don't know what's up with Halo... I can set it to the lowest settings and it still runs like an elephant with three legs, even with the -useff option for Fixed Function shaders... ah well, that's a matter for another forum, eh?
Interesting note: Sandra reports my 120gb drive as 605gb... should I be trusting it?

Apple tv slow data rate

HI Guys, i have a problem with one of my Apple TV. I currently have 2 Apple TV and one is having a slow data rate. I have Apple AirPort Time Capsule 2TB (latest gen) with most devices running on wireless connection and I checked the data rate (from the base station) on one Apple TV is showing 65Mbps and on another its showing between 6-13Mbps. The signal reception on both AppleTV is excellent. I have tried unplugging, restarting and restoring the AppleTV with no luck. The model number on this AppleTV is A1427. Any other ideas?

Hi arustandi,
Thanks for the question. If I understand correctly, one of the Apple TV's has a slow connection. I see you have already done a bit of troubleshooting. I would recommend that you read this article, it may be able to help with the slow connection.

ThinkPad Bluetooth with Enhanced Data Rate Software Problem

I'm having a weird issue. I use a X200t tablet with Windows 7 Profession 64-bit.
Apparently my current "ThinkPad Bluetooth with Enhanced Data Rate Software" is Version. 6.2.1.2900.
Thinkvantage System Update wants me to download and install Version 6.2.1.3100.
However, it tries and I get Error 1935 and it rolls back. Now when I start windows I get an alert about BTTray.exe not loading.
Of course I searched this problem, but it seems to be some ancient thing (years old) and I've never had a problem before with any of the Bluetooth updates.
I did notice that in past versions people said when they tried to uninstall the old version and install the new one, it just wiped their hard drive. I don't want to risk that so I thought I'd check here if anyone knew what was going on.
Thanks!

Dual data rate stream problem

I am streaming a live source that is being encoded at 2 different data rates. One is a 360Kbps stream, the other is a 28Kbps stream (for dial up users). I have created a reference movie that contains URLs for each of these streams. The high speed one is characterized as requiring 384Kbps DSL/Cable. The second is set to 56Kbps Modem/ISDN.
I have a Mac Mini and a PC on my desktop, both connected to my streaming server directly via the LAN. Both are running Quicktime 7.4.1. Both have their Quicktime Preference for Streaming Speed set for Automatic (The Quicktime default).
The PC always selects the high speed stream. The Mac always selects the low speed stream. The only way to make the Mac pick the correct stream is to set the streaming speed preference manually. I have even tried rebuilding the reference movie, setting the required data rate to as low as 112Kbps, but still the Mac refuses to believe it can handle that speed and picks the other one. The bandwidth to the server is actually in the Mbps range, and the stream plays just fine when it is forced to play through manual configuration.
Does anyone have any insight into why this is a problem? Better yet, does anybody have a way of making this work that doesn't involve having to explain to every user how to change their preferences?
By the way, it's not just my desktop Mac that behaves this way, the same is true for systems coming in from the outside. I'm not sure that it is necessarily clear cut that Macs always fail and PCs always succeed, or what the story is with other Quicktime releases.

How about some more information on the memory you purchasaed. If you purchased (2) 2GB sticks of memory the motherboard only supports 1GB of memory per slot and they will not function properly. Is the Patriot RAM single side or double side and did it work before you installed the 2GB modules??

What chokes H.264 footage: data rate or video dimensions?

I apologize for posting in here but this board is SO much better than the Quicktime or Compressor boards, and it's all the same workflow anyhow!
What I'm wondering is what chokes H.264 videos. Is it low bit rates? High bit rates? Big dimensions? I have an 854x480 video at 500kbps and it looks great, but even on my PowerMac there is slight stuttering, and some alpha tester feedback I've gotten tells me that a lot of slower computers are choking on the video badly.
The file size is ridiculously small, so if increasing the data rate makes it easier to decode, that would be nice.

It's neither - or either, if you will. H.264 achieves unprecedented levels of compression, which means that it's a lot more CPU-intensive to play back in real time. It simply doesn't play well on older hardware. Even slower G5s for example have problems playing back full HD H.264, particularly if it's progressive. It also depends on your GPU - certain GPUs support H.264 decoding, thus significantly offloading the CPU.
One general rule, though: the higher your data rate at any given frame size and frame rate, the less work the decoder needs to do. I'd try to go for approx. 800 kbps at your chosen frame size and see if that helps.

OFDM is a physical layer encoding technology for transmitting signals through the RF. This method breaks one high-speed data carrier into several lower-speed carriers that transmit in parallel across the particular RF spectrum. OFDM, when used with various modulation types such as 802.11g and 802.11a, is capable of supporting data rates as high as 54 Mbps.

Suggested 802.11n/ac minimum data rates

Good evening,
We presently have some minimum data rates setup for our 802.11 deployment (.11b/g disabled below 9Mbps, required at 11Mbps and supported at 12Mbps+ and for .11a/n/ac below 12Mbps disabled, 12Mbps required 12+Mbps supported). Currently in the high throughput section all MCS indices are supported. Are there are recommendations on the .11n/ac minimum supported MCS index?
We are supporting both 1142 and 2702 access points.
Thanks!

You should disable upto 11 Mbps (including 11 Mbps) & make 12 Mbps mandatory in 2.4GHz band. This will stop performance degradation due to protection mechanism enable when 802.11b client present in the network. (if you still have to support 802.11b legacy clinets then you cannot do this)
Are there are recommendations on the .11n/ac minimum supported MCS index?
leave all MCS indexes enabled. Depend on the RSSI & SNR, it will dynamically set a suitable rate. Refer this for detail

Data Rates & Cell Size

Hi all.
A few days back i was going through an article on High Density Wireless Deployments , and came through an extract which disabling Lower Data Rates , helps to reduce cell size.
How doe this work ? I mean are we exclusively allowing only those clients to associate by making the data rates disabled for slower clients ?
But isnt cell size , controlled by the Transmit power of the antenna ?
Or what we are looking here , is just reducing the cell size logically?
Thanks ,
Rahul.

No problem.... Look at it this way.... back in the days with autonomous, you could roam from one ap and not roam to the next two while walking down the hallway. So in high density, you want to have some sort of control on how many clients you want in a cell or on a particular AP. People always asked.... why an i connected to an ap 20 feet away and not the one above me. Well for one, the client chooses and also why would it roam is it is still connected at a rate that you are still supporting. There are so many tweaking involved with high density, well at least I do a lot of tweaking, but its so I can control the cell size for AP's in a high density area compared to areas where I need to extend the cell size a bit more. Data rates and TX power work hand in hand when determining this.
Thanks,
Scott

WAP4410N - mode bgn, Data rate with mixed g & n clients

Does the data rate to N connected clients go down to G rate if there is even a single G client connected?

Hello James,
Thank you for writing. The relationship between modes and effective client data rates breaks down as follows:
B, G, or N Only: The WAP only accepts clients for the particular mode defined. Clients will operate at up to the defined data rate (11 Mbps for B, 54 Mbps for G, and up to 300 Mbps for N).
B/G Mixed: The WAP will accecpt both B and G clients at their respective data rates. N clients will netotiate at the G data rate.
B/G/N Mixed: The WAP will connect all clients at their respective data rates. B clients will negotiate at only up to 11 Mbps. N clients can netogiate at up to a theoretical 300 Mbps. The WAP will accept multiple modes simulationoulsy. However, your effective data rate will only be as fast as the slowest mode connected. Therefore, connecting a B device will lower your overall data rate.
More information on this topic is found on page 28 of the Administration Guide: http://www.cisco.com/en/US/docs/wireless/access_point/csbap/wap4410n/administration/guide/WAP4410N_Admin_Guide.pdf

Variable data rate

I have a question and I'm not 100% sure how to phrase it so Ill describe my problem and maybe someone can help me.
Im working on a video composed of Gopro and DSLR footage (all converted to Prores LT). My problem is that the Gopro shots need to have a very high data rate because there is alot going on and lots of fast movement etc so the quality is only acceptable when the data rate is set to about 35 mbps. However, the DSLR footage doesnt need a data rate that high, the quality stays very high with data rates as low as ~ 6mbps (Im not exactly sure why that is? less movement maybe?).
So I dont want to export an entire video at 35mbps because that is a HUGE file. Is there such thing as a variable data rate or does anyone have any suggestions for what exactly I could do here?
Thank you in advance!

I convert all my footage to Prores LT 1280x720 at 30 fps which gives my prores clips a data rate of approximately 42 mbps I believe? and yes I'm talking end use.
Essentially what it comes down to is after I have complete editing my video in FCP and I compress it down for end use (vimeo/youtube) the only way the Gopro shots are any good is if I use an extremely high data rate (A data rate that probably isnt even supported by most video sites). There has to be a way to obtain decent quality on final compression because there are literally millions of videos out there that people have shot with gopros that are atleast decent quality. However I have found if I decrease my data rate to anything below 15 mbps the quality (of just the gopro shots) is so poor its unwatchable. Hence wondering if there was a way to set variable data rates so some of the clips are high and others are low low? Or some other work around?
