3.2.1 Scan for Other Wireless Devices
There are two kinds of wireless connection mode: Infrastructure and Ad-Hoc. Infrastructure mode is used by wireless access points, which is able to establish wireless connection for you and other wireless/wired network clients. Ad-Hoc mode is also know as ‘point-to-point’ mode, and in this mode, wireless devices such as computer or PDA will not be capable to establish wireless connection with more than one wireless device, and is suitable for establishing a one-to-one wireless connection between two wireless devices. Before connecting to any wireless access point or device by infrastructure or Ad-Hoc mode, there are two issues to be aware of:
yWireless device’s ‘SSID’ (Service Set Identifier). Users can scan for the SSID of other wireless devices nearby, but if the SSID of the wireless device is hidden, it is necessary to know exact SSID before establishing the connection.
