The types of organizations that will benefit from the advantages of the Cisco Aironet 1300 Series include education, enterprise, government, healthcare, military, public safety, transportation, and WLAN service providers. These organizations have a variety of possible applications, as shown in Figure 2 and described in the following paragraphs.
Whether the deployment is in a typical college campus or corporate offices with multiple buildings, IT professionals are faced with interconnecting local area networks around and in between each of the buildings. These LANs require cost-effective, high-bandwidth connections with seamless mobility throughout the WLAN. They also require the flexibility and control that is unavailable through leased lines or that would otherwise require trenching for new cable installations. The Cisco Aironet 1300 Series can be used as an outdoor access point, either operating with the Cisco wireless LAN controller and WCS or autonomously as an intelligent access point. It can also be used as an autonomous wireless bridge to connect remote buildings to the LAN.
Nomadic Networks and Users
More and more, networks are "on the move." Vehicles such as buses, trains, ambulances, and patrol cars are being equipped with their own LAN-supported devices, including notebooks, personal digital assistants (PDAs), cameras, and scanners. These mobile networks provide new passenger services, improved public service, and operational efficiency but they need to be interconnected to enable information-sharing and more informed decision-making. The Cisco Aironet 1300 Series can operate in autonomous mode as a workgroup bridge connecting in-vehicle devices to Cisco Aironet access points and bridges that are fixed throughout the service area.
Outdoor Public Access
The proliferation of WLAN hotspots has allowed users to stay connected while in hotels, airports, and even coffee shops. As more users desire ubiquitous connectivity, outdoor hotspots are being added-and some include multiple city blocks or even town centers. These outdoor hotspots can be cost-effectively deployed with the Cisco Aironet 1300 Series unified or autonomous access points.
The variety of temporary solutions is limitless, with applications such as remote military campaigns, short-term office leases, temporary buildings such as trailers, or even parking lot tent sales. These deployments require a temporary network infrastructure that is rugged, portable, easy to install, and flexible. The Cisco Aironet 1300 Series can be quickly deployed, with complete functionality packaged in the integrated antenna version, or with a selection of easy-to-install remote antennas for the connectorized version.

Flexible and Easy to Install
The Cisco Aironet 1300 Series adheres to the most stringent security standards in the industry. The Cisco Aironet 1300 Series is on the Federal Information Processing Standards (FIPS) 140-2 prevalidation list. FIPS 140-2 is administered by the National Institute of Standards and Technology (NIST), which dictates and validates the level of security for United States government agencies that use cryptographic-based security systems to protect sensitive electronic information. In addition, the Cisco Aironet 1300 Series meets the Common Criteria standards.
The Cisco Aironet 1300 Series supports 802.11i, Wi-Fi Protected Access 2 (WPA2), WPA, and numerous Extensible Authentication Protocol (EAP) types. WPA and WPA2 are the Wi-Fi Alliance certifications for interoperable, standards-based WLAN security. These certifications support IEEE 802.1X for user-based authentication, Temporal Key Integrity Protocol (TKIP) for WPA encryption, and Advanced Encryption Standard (AES) for WPA2 encryption. These certifications help to ensure interoperability between Wi-Fi-certified WLAN devices from different manufacturers.
The Cisco Aironet 1300 Series hardware-accelerated AES encryption supports enterprise-class, government-grade secure encryption over the WLAN without compromising performance. IEEE 802.1X authentication helps to ensure that only authorized users are allowed on the network. Backward compatibility and support for WPA client devices running TKIP, the RC4 encryption algorithm, is also supported by the Cisco Aironet 1300 Series.
Cisco Aironet 1300 Series access points operating with LWAPP support Cisco Unified Intrusion Detection System or Intrusion Prevention System (IDS/IPS), which is part of the Cisco Self-Defending Network and is the industry's first integrated wired and wireless network security solution. The Cisco Unified IDS/IPS takes a comprehensive approach to security-at the wireless edge, wired edge, WAN edge, and through the data center. When a trusted client acts maliciously, the Cisco wired IDS detects the attack and sends shun requests to the Cisco wireless LAN controllers, which will then disassociate the client device. Cisco Unified IDS goes beyond simple fire walling. If a user is allowed to access a specific server, but is not allowed to access a particular directory on the server, the anomalous behavior is detected and mitigated.
Autonomous or unified Cisco Aironet 1300 Series Access Points support management frame protection for the authentication of 802.11 management frames by the wireless network infrastructure. This allows the network to detect spoofed frames from access points or malicious users impersonating infrastructure access points. If an access point detects a malicious attack, an incident will be generated by the access point and reports will be gathered on the controller, Cisco WCS, or CiscoWorks WLSE.
A flexible outdoor wireless-bridge or access-point solution is provided through the combination of the Cisco Aironet 1300 Series, a power injector, and options for both antennas and mounting. Figure 3 shows how the units connect.
Figure 3. Network Diagram with Power Injector
Cisco Aironet 1300 Series
The Cisco Aironet 1300 Series provides the 802.11g interface for access-point capability or bridge connections. By placing the unit outdoors, close to the antenna, you can minimize the wireless cable losses-thereby maximizing the range of the network. The unit is available with either an integrated antenna, or with connectors for external antennas (Figure 4). The high-gain, integrated antenna is designed for easy installations of point-to-point links or non-root nodes of point-to-multipoint networks as an autonomous bridge. The nonintegrated antenna version provides professional installers with an RP-TNC connector that allows the deployment of omnidirectional, sector, or high-gain dish antennas for specific application requirements.
Figure 4. Cisco Aironet 1300 Series Connector Options
The Cisco Aironet Bridge Power Injector converts the standard 10/100BASE-T Ethernet interface that is suitable for weather-protected areas to a dual F-Type connector interface for coaxial cables that are more suitable for harsh outdoor environments. The power injector also provides power to the outdoor unit over the same cables with a power-discover feature and surge protection. To support longer cabling from your wired switch or router, the power injector enables total cable runs up to 200 meters (Category 5 [Cat5] and coaxial). The Cisco Aironet 1300 Series ships with the Cisco Aironet Power Injector LR2 (Figure 5) and an AC power supply.
Figure 5. Cisco Aironet Power Injector AIR-PWRINJ-BLR2/AIRPWRINJ-BLR2T
The optional Cisco Aironet Power Injector LR2T takes power from any +12 to +40 VDC source not supplied by Cisco. Typically, the DC source is a vehicle or solar-power source (Figure 6). This power injector provides the flexibility needed when an AC power source is not available.

Figure 7. Cisco Aironet 1300 Series Mounting Hardware and Antennas
The Cisco Aironet 1300 Series access point or bridge provides the following features.
Antenna Alignment Assistance
The autonomous Cisco Aironet 1300 Series provides an autoconfiguration and installation mode for quick deployment of point-to-point links without the need for configuration through Telnet, FTP, or Simple Network Management Protocol (SNMP). This mode provides LEDs with signal-strength information used in the installation and alignment process. As a result, installers are free to perform their installation process and verify the link quality without knowledge of Cisco IOS Software or data networking.
Automatic RF Configuration
Under the Cisco Unified Wireless Network, radio resource management provides automatic configuration of RF parameters for access points such as the Cisco Aironet 1300 Series Access Points. The result is a coordinated RF plan for access points under the span of the Cisco wireless LAN controller, which also recognizes the presence of other RF emitting devices. This minimizes interference to and from neighboring access points, ensuring optimal network capacity.
Seamless Layer 2 and Layer 3 Roaming
The Cisco Aironet 1300 Series provides fast secure roaming of wireless clients and autonomous non-root bridges and workgroup bridges. In both the unified access point and the autonomous access point , the encryption keys for mobile devices are cached locally, allowing the mobile device to roam between access points while remaining authenticated to the network. This significantly reduces roaming time by eliminating the need to conduct the four-way handshake with each roam. Autonomous non-root bridges and workgroup bridges also scan in the background to search for alternative Cisco Aironet access points and bridges that mobile device may be roaming to, which also reduces roaming time.
Support for Port Aggregation Protocol and Cisco Fast EtherChannel Technology
Bandwidth can be increased between bridged networks through the aggregation of multiple autonomous bridges at each site via Cisco Fast EtherChannel® technology, Port Aggregation Protocol (PAgP), or routing protocols.
Wireless Link-Distance Adjustment
For an autonomous Cisco Aironet 1300 Series device, the link-distance parameter allows the user to tune the Carrier-Sense Multiple Access/Collision Avoidance (CSMA/CA) parameters for the particular range in use to maximize performance.
Wireless Packet Concatenation
The concatenation of smaller packets into larger ones allows autonomous Cisco Aironet 1300 Series access point or bridge to more efficiently use the wireless medium and provide higher overall data throughputs.
Wireless Programmable Clear-Channel Assessment
With a programmable clear-channel assessment, an autonomous Cisco Aironet 1300 Series access point or bridge can be configured to the particular background-interference level found in your environment. This provides reduced contention overhead with other wireless systems.
The Cisco Aironet 1300 Series is a flexible outdoor 802.11b and 802.11g access point or bridge that provides high-speed and cost-effective wireless connectivity between multiple fixed or mobile networks and clients.
