3600 series with 802.11ac

[sebastian.wieseler]

Hello,

I noticed that the 3600 access point series will get an add-on module to support 802.11ac. This standard will support more than 1 GBit/s.

But the 3600 series still do only have got one GBit port. Do I only see the mistake in this plan?

And does anybody has got extended information about 802.11ac in the upcoming Cisco portfolio?

More information of the 802.11ac module will be released by the end of this year.  Stay tuned.

Maybe the adapter uses a 10 gig connection..... or larger

Let see what happens when using 802.11ac on 1gig.

802.11ac is supported only on A radio, based on the channel bonding the supported datarate varies.

roughly, it'll become 500mbps(+75mbps on G-N) due to half duplex nature, do we've an application that drives 500mbps. Since it is an edge device, it'll be connected to another AP as wgb/bridge or wireless client, shared bandwidth 500mbps remains same, using multiple hops or multiple connected device still shares this 500mbps. make sense.

3600 series should make 3x3:3 - this would be a netto bandwith of 1.3 gbps. Where did your 500 mbps come from?

Can you explain this? Also ... why half duplex? O.o

Wireless, by design, is always half duplex.  Whenever a wireless device talks, everone else has to stand back, listens and waits for their turn.

[sebastian.wieseler]

and why 500 mbps? The bandwith of one connection (okay, half duplex) should be 1.3 gbps nevertheless!?

[Leo Laohoo]

500 Mbps is, in my opinion, is expressed in HALF duplex.  So the true speed is 250 Mbps, full duplex.

[Saravanan Lakshmanan]

yes, it is 650mbps when we divide 1.3gb by 2. if you take off the L2 encryption and 802.11 MAC header it'll be around 500mbps or so. Remember, To achieve the max throughput, all the up & down wireless packets has to use highest available datarate all the time or that calculating interval.

on tri radio:

650(802.11ac) + 100(802.11G-N) + 225(802.11A-N) => 975mbps.
