Network fault tolerance for LAN clients
LAN to LAN over internet*nix CARP or VMWare Fault Tolerance?How to detect weak points in my lanNeed help diagnosing network performance issuesWhat Are VMware ESXi/vSphere Fault Tolerance Bandwidth RequirementsHow to implement a network fault tolerance on a Windows Server 2008 R2, Single Server - Dual NIC? Only Windows Services like DNS, DHCP, File ServerExtend wireless LAN with several access points?Ethernet Router, switch and network routesHow to configure two firewalls for two WANs and one LANConfiguring a switch with WAN and LAN
Goal: Provide fault tolerance for LAN clients so access to a service with a service-level agreement (SLA) is not interrupted in the event of an incident with a physical switch.
Question: Is there a configuration which would provide fault tolerance for LAN clients over Ethernet via a single wall port per client?
Stop reading here if the answer to my first question is yes.

With Ethernet, In the following topology if the switch stops working the client no longer has access to services provided over the LAN.
client<--> wall port <--> patch panel <--> switch
With Wi-Fi, In the following topology if a single switch stops working the client continues to have access to services provided over the LAN, if the client is in range of both access points (AP) 01 and 02.

I'm unaware if there is a standard for Wi-Fi clustering. The type I am referring to is present in Linksys LAPAC line of Wi-Fi access points.
While two NICs and two wall ports for each client would overcome this limitation, it is unrealistic in a usual office environment.
In this scenario would it be preferential to use Wi-Fi with clustering? If so, am I correct in assuming that it would it imply that Wi-Fi with clustering delivers better uptime (especially with mobile devices)?
From a best practices perspective how would this configuration be considered?
Thank you for your answers and input.
