Cisco’s 1100 Series Wi-Fi Wireless LAN SoHo Solution:

The Cisco Aironet ® 1100 Series Access Point provides a secure, affordable, and easy-to-use Wi-Fi wireless LAN (WLAN) solution that combines mobility and flexibility with the enterprise-class features required by networking professionals. Taking advantage of the Cisco Wireless Security Suite for the strongest enterprise security available and of Cisco IOS ® Software for ease of use and familiarity, the Cisco Aironet 1100 Series Access Point delivers manageability, performance, investment protection, and scalability in a cost-effective package with a low total cost of ownership. The Cisco Aironet 1100 Series features a single, upgradeable 802.11b radio, integrated diversity dipole antennas, and an innovative mounting system for easy installation in a variety of locations and orientations.

Figure 1: An access point is the center point in an all-wireless network or serves as a connection point between a wired and wireless network. Multiple access points can be placed throughout a facility to give users with WLAN adapters the ability to roam freely throughout an extended area while maintaining uninterrupted access to all network resources

Intelligent Networking Features for a Scalable, Manageable Solution

The first access point based on Cisco IOS Software, the Cisco Aironet 1100 Series extends end-to-end intelligent networking to the wireless access point. Cisco command-line interface (CLI) allows customers to quickly and consistently implement extended capabilities available in Cisco IOS Software. Customers can manage and standardize their networks using tools they have developed internally for their Cisco routers and switches.

Enterprise-class features including virtual LANs (VLANs), quality of service (QoS), and proxy mobile Internet Protocol (IP) make the Cisco Aironet 1100 Series ideal for enterprise installations. The Cisco Aironet 1100 Series also supports standard Cisco Aironet features such as hot-standby and load balancing, allowing enterprises to implement intelligent, reliable network services.

The Cisco Aironet 1100 Series is capable of managing up to 16 VLANs (Figure 2), which allows customers to differentiate LAN policies and services, such as security and QoS, for different users. For example, enterprise customers can use different VLANs to segregate employee traffic from guest traffic, and further segregate those traffic groups from high-priority voice traffic. Traffic to and from wireless clients with varying security capabilities can be segregated into VLANs with varying security policies. For example, it allows educational institutions to secure faculty and administrator traffic from student traffic traveling over the same infrastructure.

Figure 2: Indoor Wireless VLAN Deployment

With support for 802.1p QoS, the Cisco Aironet 1100 Series provides traffic prioritization for packets traveling to and from the access point over Ethernet. Delay-sensitive traffic, such as voice and video, can be prioritized over data traffic for improved user experience and optimal network utilization. Software and radio firmware upgrades provide the capability to upgrade to future QoS standards such as 802.11e. Supporting the voice prioritization schemes for 802.11b mobile phones, the Aironet 1100 Series further enables quality voice-over-wireless-LAN solutions.

With proxy mobile IP, users can maintain seamless network connectivity as they roam across subnets. By transporting user IP addresses as they move from one subnet to the next, the Cisco Aironet 1100 Series enables IT professionals to architect the wireless LAN in a manner more consistent with the wired LAN, while still maintaining user mobility. More segmented networks provide greater manageability than traditional flat wireless LANs.

The Cisco Aironet 1100 Series can be easily managed through the CLI or HTTP-based graphical user interface (GUI), using tools such as File Transfer Protocol (FTP), Trivial File Transfer Protocol (TFTP), and Telnet. The Cisco Aironet 1100 Series can be integrated with CiscoWorks solutions by using standard Management Information Base (MIB) I and MIB II and Simple Network Management Protocol (SNMP), to provide feature-rich, even greater enterprise management capabilities through CiscoView, Resource Management Essentials (RME), and Campus Manager.

Enterprise-Class Wireless LAN Security

Wireless LAN security is a primary concern. The Cisco Aironet 1100 Series secures the enterprise network with a scalable and manageable system featuring the award-winning Cisco Wireless Security Suite. Based on the 802.1X standard for port-based network access, the Cisco Wireless Security Suite takes advantage of the Extensible Authentication Protocol (EAP) framework for user-based authentication (Figure 3).

The Cisco Wireless Security Suite interoperates with a range of client devices. It supports all 802.1X authentication types, including EAP Cisco Wireless (LEAP), Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) and types that operate over EAP-TLS, such as Protected Extensible Authentication Protocol (PEAP), EAP-Tunneled TLS (EAP-TTLS) and EAP-Subscriber Identity Module (EAP-SIM). A wide selection of Remote Access Dial-In User Service (RADIUS) servers that support these same authentication types can be used for enterprise-scalable centralized user management. Enhanced features such as pre-standard Temporal Key Integrity Protocol (TKIP) per-packet key hashing, message integrity check (MIC), and broadcast key rotation are integral to the Cisco Wireless Security Suite.

Simplified Deployment for Rapid Connectivity

The Cisco Aironet 1100 Series, with its redesigned GUI, introduces the next level of intuitive, browser-based management for an improved user experience (Figure 4). A menu-based organization simplifies navigation and configuration for easy setup and ongoing management with uncompromised security. The Cisco Aironet 1100 Series can also be managed using Cisco IOS Software CLI, which is familiar to IT professionals and makes use of their existing skills.

Figure 4: The redesigned GUI in the Aironet 1100 Series provides intuitive browser-based management for basic configuration of the access point.

The Cisco Aironet 1100 Series defines enterprise office deployment capability. Designed in an attractive, durable plastic enclosure, with integrated diversity dipole antennas, the Cisco Aironet 1100 Series provides for quick deployment with a reliable, omni-directional coverage pattern. Supported in various mounting orientations and locations, it can be easily moved throughout the work area as needs change (Figure 5). A standard surface-mounting bracket supports installation on office walls and ceilings for elevated placement. The broad operating temperature range and UL 2043 certification for plenum rating requirements set by local fire codes supports installation in environmental air spaces such as areas above suspended ceilings. The design protects against tampering and theft using single- or master-keyed padlocks. The Cisco Aironet 1100 Series can also be brought into the cubicle space with a cubicle wall-mounting bracket or device stand. The device stand positions the access point on any horizontal surface, such as a desktop or shelf. Theft is deterred in these installations using the security slot with standard security cables. Support for either local or inline power over Ethernet further simplifies installation. The Cisco Aironet 1100 Series is Wi-Fi certified to ensure interoperability with other IEEE 802.11b devices.

Cost-Effective Solution for Evolving Requirements

The Cisco Aironet 1100 Series is ideal for new deployments, or as an addition to existing deployments to support increasing capacity requirements. Engineered with extra system capacity, including memory, storage, and processing power, the Cisco Aironet 1100 Series is designed to support not only today's feature set, but future software releases for expanded functionality and capabilities. Companies can also upgrade the Cisco Aironet 1100 Series hardware to future radio technologies, such as those based on higher speed 802.11g specifications, unleashing increased performance and further investment value.
