High-Performance Outdoor Access Point for Wireless Sensor Networks

The Cisco® Aironet® 1552S Outdoor Access Point is the latest model in the Cisco Aironet 1550 Series. The 1552S merges the ruggedized outdoor 802.11n access point with an integrated, ISA100-compliant backbone router to provide a seamless solution for wireless sensor networks. The ISA100.11a radio has been designated specifically for mission-critical wireless connectivity to industrial sensor equipment. With an ISA100.11a radio integrated in an 802.11n-based access point, a single solution addresses the growing need for wireless mobility while also providing mission-critical connectivity for industrial sensing and monitoring equipment, such as gauges for water treatment plants, sensors for chemical plants, and vibration monitoring solutions for oil rigs.
This allows customers to combine business use cases, such as:

Monitoring a chemical treatment plant while providing onsite security via wireless video surveillance

Monitoring the equipment and gauges on an oil rig while an onsite worker downloads schematics, blueprints, or work instructions to a handheld Wi-Fi tablet

Providing real-time information to an onsite engineer about changes to processes and equipment so that abnormalities can be dealt with immediately

The Cisco Aironet 1552S Access Point is also Class 1, Div 2/Zone 2 hazardous location certified. This means it is designed specifically for hazardous environments like oil and gas refineries, chemical plants, mining pits, and manufacturing facilities. The 1552S offers a single-box solution rather than requiring two separate wireless networks―one for 802.11n and one for ISA100 sensor networks.

By eliminating the extra power and network connections, which can be expensive to deploy in hazardous locations, the 1552S saves costs by reducing deployment times while offering a flexible, secure, and scalable mesh network for high-performance wireless coverage for both Wi-Fi clients and ISA100.11a field instruments across large facilities. With all these benefits, the Cisco Aironet 1552S Outdoor Access Point can improve overall plant reliability, safety, and profitability.

The Cisco Aironet 1552S Outdoor Access Point supports multiple-device and multiple network application delivery methods, such as real-time seamless mobility, video surveillance, 3rd Generation (3G) and 4G data offload, and public and private Wi-Fi access. Designed to meet customer needs in a broad range of industries, the Cisco Aironet 1552S Outdoor Access Point offers the following additional benefits:

Flexible deployment options: Access or mesh network, extension of an Ethernet network, and Ethernet, fiber, or wireless backhaul.

Cisco CleanAir® technology: Integrated spectrum intelligence to detect, classify, and mitigate RF interference from unauthorized wireless bridges or malicious devices.

High-bandwidth video surveillance: Video surveillance over Wi-Fi without the high cost of installing cables over long distances.

High-performance, multipurpose network: Provides low CapEx and OpEx.

Integrated wired and wireless: The Cisco Borderless Network Architecture provides cost savings with end-to-end network access solutions that include wireless, switching, routing, and security.

Flexible, High-Performance Mesh

The Cisco Aironet 1552S Outdoor Access Point offers a flexible, secure, and scalable mesh platform that is part of the Cisco Unified Wireless Network. It offers high-performance mobility across large oil and gas facilities, chemical plants, manufacturing yards, and mining pits. The 1552S provides high-performance device access through improved radio sensitivity and range with 802.11a/b/g/n multiple-input multiple-output (MIMO) technology including two spatial streams. Multiple uplink and power options are available. The 802.3af-compliant, Power-over-Ethernet (PoE) interface makes it easy to connect IP devices, such as IP video cameras. The housing is certified for Class1, Div 2/Zone 2 deployment areas and provides a robust system that can withstand demanding, hazardous environments.

Cisco CleanAir Technology

As part of the Cisco Aironet 1550 Series with Cisco CleanAir technology, the 1552S provides the highest-performance 802.11n connectivity for mission-critical outdoor networks by detecting interference from unauthorized devices, as well as common outdoor interference sources such as WiMAX networks and wireless bridging products. The 1550 Series uses chip-level intelligence to create a spectrum-aware, self-healing, and self-optimizing wireless network that mitigates the impact of wireless interference. Cisco CleanAir technology is a systemwide feature of the Cisco Unified Wireless Network that improves wireless network quality by detecting RF interference that other systems can’t recognize, identifying the source, locating it, and then making automatic adjustments to optimize wireless coverage.

RF Excellence

Building on the Cisco Aironet heritage of RF excellence, the Cisco Aironet 1550 Series delivers industry-leading performance for secure and reliable wireless connections. Industrial-grade parts, enterprise-class silicon-level intelligence, and optimized radios deliver a robust mobility experience. The Cisco Aironet 1550 Series provides a set of tools that deliver the robust, scalable wireless foundation required to realize the true potential of outdoor wireless mobility:

Cisco ClientLink technology to raise the downlink performance to 802.11a/g clients, providing improved coverage and throughput to existing clients

Radio resource management (RRM) for automated channel selection and power setting management of access points

Advanced capabilities to select data rates, adjust power, and manage quality of service (QoS) for access points

Centrally Managed Mesh Network

Central management and troubleshooting of the Cisco outdoor wireless access points prevent costly maintenance service calls to outdoor locations. The Cisco Prime Network Control System (NCS) works in conjunction with the Cisco Aironet Access Points and Cisco Wireless LAN Controllers to configure and manage the wireless networks. With Cisco Prime NCS, network administrators have a single solution for RF prediction, policy provisioning, network optimization, troubleshooting, security monitoring, and wireless LAN systems management. Cisco CleanAir technology is integrated into Cisco Prime NCS to provide real-time information on your outdoor network. Wireless network security is also a part of a unified wired and wireless solution. Cisco wireless network security offers the highest level of network security, which helps ensure that data remains private and secure and that the network is protected from unauthorized access.

802.11n Outdoor Access Point

The Cisco Aironet 1552S Outdoor Access Point contains a dual-radio system with radios that are compliant with IEEE 802.11a/n (5-GHz) and 802.11b/g/n (2.4-GHz) standards. The 1552S has three external antenna connections for three dual-band antennas. It has Ethernet and fiber Small Form-Factor Pluggable (SFP) backhaul options. This access point also has a PoE-out port and can power a video surveillance camera. A highly flexible model, the Cisco Aironet 1552S is designed for hazardous environments like oil and gas refineries, chemical plants, mining pits, and manufacturing factories. The Cisco Aironet 1552S Outdoor Access Point is Class 1, Div 2/Zone 2 hazardous location certified.

ISA100-compliant Backbone Router

The Cisco Aironet 1552S Outdoor Access Point houses an ISA100.11a-compliant backbone router (BBR) that provides backhaul transport of the wireless sensor network traffic. The dual-radio BBR is based on the IEEE 802.15.4 standard and communicates to all ISA100.11a-compliant wireless field sensor devices. The BBR can also receive secure configuration codes via a windowed, infrared (IR) receiver.

External Antennas

The Cisco Aironet 1552S use three Cisco AIR-ANT2547V-N-HZ antennas. These dual-band, omnidirectional, stick antennas have a gain of 4 dBi (2.4 GHz) and 7 dBi (5 GHz) and are IP66 rated for robustness in corrosive environments.

The Cisco Aironet 1552S also uses two Cisco AIR-ANT2450V-N-HZ antennas for the 802.15.4 diversity radios. These 2.4-GHz band omnidirectional, stick antennas have a gain of 5 dBi and are IP66 rated.
