What is the difference between infrastructure and ad hoc
networks?
Wireless networks can operate in one of two modes: infrastructure or ad hoc.
In infrastructure mode, all devices on a wireless network communicate with each other through a wireless router.
Devices on the wireless network must have valid IP addresses for the current network and share the same SSID and
channel as the wireless router (wireless access point).
In ad hoc mode, a computer with a wireless network adapter communicates directly with a printer equipped with a
wireless print server. The computer must have a valid IP address for the current network and be set to ad hoc mode.
The wireless print server must be configured to use the same SSID and channel that the computer is using.
The following table compares the characteristics and requirements of the two types of wireless networks.
