I am planning to have a wireless environment for a corporate company. I would like to have a Cisco wireless LAN controller 2100 series and 15 numbers of cisco aironet 1142 n access point. Since wireless is gonna be a very important medium for the premises, I am planning to have high availability for the 2100 series WLC.
With this scenario I am having the following of queries?
1. Does high availability is supported with WLC 2100 series or need to go for an hihger end WLC's? It would be great if I am guided with some documents on this?
2. My wired switching infrastructure at the core is running with GLBP. Can I connect the both WLC in each switch in an dual home architecture?
3. Is there any pre-requistes for doing the high availability for the WLc's?
4. Yet another company that is close to me do have the same architecture for wireless infrastructure, except that they have cisco WLC as 5508 and Cisco aironet 1142n access point. All the end points NIC adapters that they have support a/b/g standard. But with an n series they continously report low signal strength, the reason for this still unknown?
But the tech documents of 'n' series access point claims that they support, 300Mbps within 33 feet and 200 Mbps within 66 feet.
They are having 2 nos of Cisco 1142n access point for every 30 feet but still they are facing low signal strength. Also there workspace are all cubicles and without any interference.
It would be great if I am guided on this issue also?
