If your administration asked you to consider a distributed architecture, what other (vendor-neutral) concerns would you have? There's a middle ground between thick and thin - relatively thick APs, that are centrally managed but with enough smarts to process traffic locally. 802.11ac will have an effect here, as each thin AP could theoretically require 1Gb/s to the controller. This is why Cisco is putting controllers in its switches, to distribute the traffic load. Most controller-based vendors do support local bridging, but some will not support all features or not maintain sessions if the controller fails. I haven't really looked at the new range of thick APs like Meraki or Aerohive, so can't comment on their architecture. -- James Andrewartha Network Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph.

RE: Distributed WiFi model - Thin vs Thick debate revisited
Jacob, You mention a sup card. That indicates that your Aruba hardware is EOL and cannot run the latest code. The EOL was announced in 2010. Aruba's latest 7200 series controllers(the current successor to the Sup controllers) have been designed with 802.11ac in mind, If you upgrade now you would not need to upgrade the controller for 802.11ac Wi-Fi. The controller provides central management intelligence to the wireless system, If the controller load specs are exceeded, data path issues can result,. You would also have client issues if there are too many clients on an AP. That does not mean you move away from deploying APs though. Somebody mentioned managing APs with Airwave, Remember, Airwave is owned by Aruba, so I would expect them to better support their own products and possible deprecate support for other vendors.

To answer some questions: We have 145 ap's deployed. However that is likely to go up as we address high density areas and re-deploy for 5GHz. Some of that will happen as part of this summer's upgrades. Unfortunately, I cannot afford a complete overhaul so we would have to maintain both systems for at least one more academic year. That does weigh heavily on our decision. Regarding a/c, please correct me if I am mistaken, but I believe that the investment should wait until rev2 or whenever multi-user MIMO is mainstream. I anticipate the distributed environment to be much more conducive to the newest ratification. I will not have to upgrade a controller again, rather only replace the AP. Our controller is dropping clients. Aruba has confirmed that this is the case and only offered to sell me an updated sup card as a fix. We do have had several cases open and still do now. Effort is not in question here, just results. Unfortunately having redundant controllers never fit into our budget model. With a distributed model, no redundancy is needed. We are considering Aerohive, using the HiveManager installed on a VM instead of the cloud-based version. I have had four Aerohive AP's running in an off-campus dorm this academic year and am pleased so far. It is a single point of management and metric gathering similarly to the Aruba web UI, but with all metrics included, not needing an additional server i.e. Airwave. The greatest management disadvantage I have identified so far is that changes to any AP require a reboot. With Aruba, I can make many changes in real time. I am trying to build a long term cost analysis considering a five year life for each AP. At first estimates, the costs appear to be similar and not a key decision point. POE costs are a definite concern, but that exists with whatever architecture model we choose. So far, I do not believe anyone has thrown a red flag. Is that a fair assessment?

Having said that, if there is any interruption (internet, problems with firewall, their site, whatever) the only downside would be that we could not install apps, change settings, etc. until the issue was rectified. I hesitate to put something that is more critical, like a wireless controller, offsite as it is a more time sensitive system. Even without internet our users can logon and work locally. We are using a Ruckus ZD3000 with 31 APs and have had zero downtime, coverage is excellent, and speeds are fast. We feel strongly enough about it we purchased a second ZD3000 and have them synced at all times. The failover is instant (almost) and the second unit was very inexpensive. Best thing about the Ruckus is the interface is MUCH easier than the Aruba that we retired. . The APs act independent from the controller (for the most part.

Re: [WIRELESS-LAN] Distributed WiFi model - Thin vs Thick debate revisited
Don't forget. Meraki is Cisco. They bought them, but running them as an independent unit. Cisco also has they're Flex controller, which is a similar model. I haven't seen any other vendor with Aerohive's model. I haven't used it, just sat through a few sales presentations. But from what I've seen, it's very interesting. It's not as cut and dried as it was 1 year ago. The Thick/Thin models are merging in more ways than one.

Ideas 1. Same ssid across both systems and let the clients choose what system. 2. Samessid and adjust the probe/reponse thresholds so clients outside of a building don't connect. 3. Have versions of ssids for each system so clients can choose what ssid to connect to.

Question about the signal strength of cisco Aironet 3602E on 5GHz
Dear All We found that the signal strength of cisco Aironet 3602E (with omni directional antenna AIR-ANT2524DW-R) on 5GHz is quite unstable (2.4GHz is good). I am using a HP win7 laptop, and sitting 5 meters away from the AP. Usually the signal strength on the laptop is only one or two bars (out of 5). However, I use some third party application (e.g. Xirrus, Ekahau), the signal strength is -47 (almost same value as shown on the controller). Do you have the similar problem? Is it a bug of Win7 or Cisco WLC (We are using version 7.2.111.3)? Have a nice day.
