IMPORTANT

Infrastructure Mode

This is an 802.11 networking framework in which devices communicate with each other by first going through an access point (AP). In Infrastructure mode, wireless devices can communicate with each other or can communicate with a wired network. When one AP is connected to a wired network and a set of wireless stations, it is referred to as a basic service set (BSS). An extended service set (ESS) is a set of two or more BSSs that form a single sub network. Most corporate wireless LANs operate in Infrastructure mode because they require access to the wired LAN in order to use services such as file servers or printers.

Ad hoc Mode

This is an 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an AP. Ad hoc mode is also referred to as Peer-to-Peer mode, or an independent basic service set (IBSS). Ad hoc mode is useful for establishing a network in which a wireless infrastructure does not exist or in which services are not required.

SSID (service set identifier)

This is a 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because, essentially, it is a name that identifies a wireless network.

To connect a wireless client such as a Wireless Pro Series Network Camera to a specific AP, the user of the camera should specify the SSID name in the camera’s wireless IP setting.
