CH A P T E R3Wireless Local Area NetworkA Wireless Local Area Network (WLAN) implements a flexible data communication system frequentlyaugmenting rather than replacing a wired LAN within a building or campus. WLANs use radio frequencyto transmit and receive data over the air, minimizing the need for wired connections.The Cisco 819HGW and Cisco 819HWD ISRs have a Host router software running on the first core. Thesecond core runs the WLAN Access Point software.If WLAN is not supported in an SKU, all 1 GB DRAM memory is allocated to the first core. For theSKUs that support WLAN, 128 MB out of the 1 GB main memory is allocated to the second core.If WLAN is not supported in an SKU, all 1 GB compact flash memory is allocated to the first core. Forthe SKUs that support WLAN, 64 MB out of the 1 GB main memory is allocated to the second core.NoteWLAN is only supported on Cisco 819HGW and Cisco 819HWD ISRs introduced in IOS release15.2(4)M1.WLAN FeaturesThe Cisco 819HGW and Cisco 819HWD ISRs support the following features: Dual-Radio, page 3-1 Images Supported, page 3-2 CleanAir Technology, page 3-2 Dynamic Frequency Selection, page 3-2 LEDs, page 3-2Dual-RadioThis release supports Cisco 802 Access Points (AP802). The AP802 is an integrated access point on theNext Generation of Cisco 819HGW Cisco 819HWD ISRs.The access point is a wireless LAN transceiver that acts as the connection point between wireless andwired networks or as the center point of a standalone wireless network. In large installations, the roamingfunctionality provided by multiple access points enables wireless users to move freely throughout thefacility while maintaining uninterrupted access to the network.Cisco 819 Series Integrated Services Routers Software Configuration GuideOL-23590-023-1

Chapter 3Wireless Local Area NetworkWLAN FeaturesAP802 Dual Radio contains two different types of wireless radio that can support connections on both2.4 GHz used by 802.11b, 802.11g, and 802.11n and 5 GHz used by 802.11a and 802.11n.With the dual-radio/dual-band IEEE 802.11n access point, the Cisco 819HGW and Cisco 819HWD ISRsoffer a secure, integrated access point in a single device. The ISRs support both autonomous and unifiedmodes and are backward compatible with 802.11a/b/g.The routers support IEEE 802.11n draft 2.0 and use multiple-input, multiple-output (MIMO) technologythat provides increased throughput, reliability, and predictability.For complete information on how to configure wireless device and radio settings, see Basic WirelessDevice Configuration and Configuring Radio Settings.Images SupportedFor the images supported in the AP802 Dual radio, see Minimum software version needed to supportAP802.CleanAir TechnologyThe CleanAir is a new wireless technology that intelligently avoids Radio Frequency (RF) to protect802.11n performance. For more information, see Cisco CleanAir Technology. This feature is supportedin all SKUs.Dynamic Frequency SelectionThe Dynamic Frequency Selection (DFS) is the process of detecting radar signals that must be protectedagainst 802.11a interference and upon detection switching the 802.11a operating frequency to one thatis not interfering with the radar systems. Transmit Power Control (TPC) is used to adapt the transmissionpower based on regulatory requirements and range information.NoteThe DFS functionality is disabled for FCC SKUs pending FCC certification. For more information, seeDynamic Frequency Selection and IEEE 802.11h Transmit Power Control.LEDsThe WLAN LED is located at the front panel of the router. Table 3-1 describes the WLAN LED for theCisco 819HGW and Cisco 819HWD ISRs.Cisco 819 Series Integrated Services Routers Software Configuration Guide3-2OL-23590-02
