DESCRIPTION: Time Division Multiple Access Complete Definintion: Time Division Multiplex Access (TDMA). Type of multiplexing where two or more channels of information are transmitted over the same link by allocating a different time interval ("slot" or "slice") for the transmission of each channel, that is, the channels take turns to use the link. Some kind of periodic synchronizing signal or distinguishing identifier usually is required so that the receiver can tell which channel is which. See also TDM. Wikipedia TDMA Definition. ...

    Introduction   Cisco Wireless LAN Controllers work in conjunction with Cisco lightweight access points and the Cisco Wireless Control System (WCS) to provide system wide wireless LAN functions. As components of the Cisco Unified Wireless Network, Cisco 2100 Series Wireless LAN Controllers present network administrators with the visibility and control necessary to effectively and securely manage business-class WLANs and mobility services, such as voice, guest access, and location services.   The Cisco 2106 Wireless LAN Controller works in conjunction with Cisco lightweight access points and the Cisco Wireless Control System ( WCS ) to provide system wide wireless LAN functions. As a component of the Cisco Unified Wireless Network, the Cisco 2106 Wireless LAN Controller gives network administrators the visibility and control necessary to effectively and securely manage business-class WLANs .   The Cisco 2106 Wireless LAN Controller provides: A cost-effective solution for enterprise branch deployments and small and medium-sized business environments Business-class RF security and WLAN security policy monitoring Simplified network deployment, operations, and management to help reduce overall operational expenses   These controllers are part of a Payment Card Industry (PCI) certified architecture, and are well suited for retail customers who deploy transactional data applications such as scanners and kiosks. With performance up to 100 Mbps, the Cisco 2100 Series Wireless LAN Controllers also enable small and medium branch offices to deploy collaboration applications such as guest access and mobile voice.   While Cisco 2100 Series Wireless LAN Controllers support transaction-oriented wireless environments such as handheld scanners in retail, the Cisco 5500 Series Wireless Controllers are recommended for high-data-rate and multicast-intensive applications such as large data files, video, push-to-talk.   Features and Benefits   Features and Benefits of the Cisco 2100 Series Wireless LAN Controllers     Features Benefits Eight 10/100 Ethernet Ports Provides eight 10/100 Ethernet ports, intended to support a combination of access points and redundant LAN uplinks Power-over-Ethernet-Enabled Ports Two of the eight 10/100 Ethernet ports are 802.3af Power over Ethernet (PoE) and Cisco PoE enabled, rated for use with Cisco Aironet® lightweight access points Small Form Factor Allows for convenient desktop mounting or rack mounting, with optional rack mount kit for flexible deployment Extended Secure Coverage Extended secure coverage for larger stores and warehouses PCI Integration Supports a PCI-certified architecture for retail customers Support for 802.11n Offers robust coverage with 802.11 a/b/g or delivers unprecedented reliability using 802.11n and Cisco Next-Generation Wireless Solutions and Cisco Enterprise Wireless Mesh     Cisco 2100 Series Models and Number of Access Points Supported   2100 Series Controllers # of Access Points Supported Cisco 2106 6 Cisco 2112 12 Cisco 2125 25     New Features   Cisco Unified Wireless Network Software Release 6.0 is supported by the following devices: • Cisco Aironet access points running Lightweight Access Point Protocol (LWAPP) • Cisco 2100, 4400, and 5500 Series Wireless Controllers • Cisco Aironet 1524 Outdoor Mesh Access Point • Cisco Catalyst ® 6500 Series/7600 Series Wireless Services Module (WiSM) • Cisco Wireless LAN Controller Module (WLCM) and Cisco Wireless LAN Controller Module Enhanced (WLCM-E) for integrated services routers • Cisco Catalyst 3750G Integrated Wireless LAN Controller • Cisco 3300 Series Mobility Services Engine • Cisco 2700 Series Wireless Location Appliance • Cisco WCS and Cisco WCS Navigator     PRODUCT LITERATURE   Bulletins All Cisco 2100 Series Wireless LAN Controllers Bulletins Cisco Unified Wireless Network Software Release 4.0 206.0 Data Sheets All Cisco 2100 Series Wireless LAN Controllers Data Sheets Cisco 2106 Wireless LAN Controller Data Sheet   Q & A All Cisco 2100 Series Wireless LAN Controllers Q&A Cisco 2100 Wireless LAN Controller Q&A Cisco Unified Wireless Network Software Release 4.0.197.0 Q&A Wireless LAN Controller (WLC) Error and System Messages FAQCross-Navigate ...
