2.7 Install and configure wireless LAN infrastructure and implement the appropriate technologies in support of wireless capable devices
Small office/home office wireless router
Multifunction device designed to work alone
All configuration, security and setting are stored individually.
Wireless access points
2 types: LWAPs and Autonomous APs
Device density
How many users can an AP handle?
Roaming
moving been APs
Wireless controllers (WLCs)
Centralized Controller for configuring multiple Lightweight APs
Provides all APs with policies, SSID, and radio profiles
VLAN pooling (Diagram)
One SSID + many wireless clients = large broadcast domain
Possibly run out of IP addresses
When devices are roaming could lose IP
LWAPP (Lightweight Access Point Protocol)
Cisco proprietary protocol to centrally control APs
Cisco APs detect best Wireless LAN Controller (WLC)
Each AP can download from the controller Policies, SSID and radio profile dynamically and automatically.
Wireless bridge (not a Wi-Fi Bridge)
Connects 2 LAN segments using IR or Microwave, where laying cable is prohibited. E.g. Between buildings
Can help to secure access to public hotspot. i.e. It becomes a gateway for those connected to AP.
Wi-Fi Bridge is connecting two 802.11 networks together to expand Wi-Fi coverage area.
