Ethernet is a CSMA/CD technology. c) The WAP includes an 802.11 interface for coupling to the 802.11 wireless network which provides a wireless bidirectional communications path. d) The WAP includes a controller that implements the medium access control (“MAC") protocol as defined in IEEE 802.11. In accordance with the MAC protocol. the controller provides information that controls when wireless devices connected to the network are allowed to transmit, thereby causing the communications over the wireless network to occur in a half-duplex manner. o) The WAP includes a first buffer that holds frames received from the Ethernet network sia the Ethernet interface and then supplies those frames via the 802.ll interface to the wireless network. l) The WAP includes a second buffer that holds frames received from the wireless network via the SO2.} I interface and then supplies those frames via the Ethernet interface to the Ethernet network. Furthermore. your company is infringing at least claim 48 ofthe ‘895 Patent by making a wireless network that includes all claimed elements in at least the following manner: a) The WAP in your WiFi network provides communication with a CSl\A.»\/Cl) network (an Ethernet network) via a bidirectional communications path (an 802.l l wireless path). lt:) The VVAP is located at a first end of the SO2.l l wireless path and includes an Ethernet interface to an Ethernet network. Ethernet is a CSMA/CD technology. The WAP incudes a buffer for buffering information packets received from the Ethernet network via the Ethernet interface for supply to the 8(l2.l I wireless path. The WAP also includes a buffer for buffering infoirnation packets received from thc 802.l l wireless path for supply to the Ethernet network via the Ethernet interface. The WAP also includes a controller that implements the medium access control ("MAC") protocol as detined in IEEE 802.l l. c) A wireless station is connected at a second end of thc 802.l l wireless path. The wireless station includes a buffer for buffering information packets received fiom the 802.l 1 wireless path, a buffer for buffering information packets to he supplied to thc 802.1 l wireless path, and a MAC controller. d) ’l`hc MAC controller in the WAP and the MAC controller in thc wireless station are arranged to exchange control information over the 802.l l wireless path so as to allow information packets to be communicated bi-directionally over the 802.1 I wireless path between the buffers ofthe WAP and the wireless station in a haltlduplex manner. In addition to directly infringing the IWS Patents. your company is also inducing others to infringe the IWS Patents by offering wireless Internet access, advertising that wireless Internet access, and encouraging others to use that wireless Internet access. These other entities include your company’s guests, customers, and end users, whose connection of their wireless devices to your network and use of the wireless Internet access constitutes direct infringement of the IWS Patents.
