The Cisco Aironet 1540 Series outdoor access points are designed to provide high-performance, reliable wireless connectivity in a rugged and compact form factor. These devices are specifically engineered to meet the growing demands of service providers and enterprise networks that require fast, secure, and stable links for mobile users and wireless backhaul applications.
By supporting the 802.11ac Wave 2 standard, the 1540 Series ensures that modern bandwidth-intensive devices, such as smartphones, tablets, and laptops, receive the throughput necessary for a seamless user experience. The series is built to be easily deployed in various environments, offering flexibility for both traditional access point setups and wireless mesh network configurations.
Product overview
The Cisco Aironet 1540 Series consists of two primary models: the AIR-AP1542I and the AIR-AP1542D. Both models are housed in an ultra-low-profile, aesthetically pleasing enclosure that allows for discreet mounting on walls or light poles without compromising the visual appeal of the deployment area. Despite their small size and lightweight design, they are built to withstand harsh outdoor conditions.
These access points are highly versatile, supporting multiple deployment modes including the Cisco Mobility Express solution, which is ideal for small to medium-sized networks that do not require a physical controller. The series is designed for efficiency, operating on standard 802.3af power, and provides robust wireless performance through advanced features like MU-MIMO and spatial streaming, ensuring that network operators can balance coverage requirements with ease of installation.
Features and benefits
- 802.11ac Wave 2 Standard: Delivers data rates of up to 867 Mbps on the 5-GHz radio, with a total aggregate dual-radio data rate of up to 1.1 Gbps.
- Multiuser MIMO (MU-MIMO): Enables simultaneous data transmission to multiple Wave 2-capable clients, significantly improving the overall client experience.
- Compact and Rugged Design: Features a lightweight, small-footprint housing that is IP67 rated for environmental protection against dust, water, and extreme temperatures.
- Flexible Deployment Options: Supports traditional access point and wireless mesh configurations, as well as the Cisco Mobility Express solution for controller-less deployments.
- Integrated Antenna Options: Includes two distinct models—the 1542I with omnidirectional antennas for general coverage and the 1542D with directional antennas for targeted connectivity.
- Low Power Consumption: Operates efficiently on standard 802.3af power (13.9W), simplifying power management in outdoor installations.
- Advanced Security: Provides enterprise-grade security, including WPA2, 802.1X authentication, and support for various EAP protocols to ensure secure network access.
Cisco Aironet 1540 Series outdoor access points offer the latest 802.11ac Wave 2 functions in a rugged, ultra-low-profile housing that service providers and enterprises can deploy easily.
The Cisco Aironet 1540 Series is ideal for applications requiring rugged outdoor Wi-Fi coverage and supports the latest 802.11ac Wave 2 radio standard. Housed in a compact, aesthetically pleasing, easy-to-deploy package, the 1540 Series offers flexible deployment options for service providers and enterprise networks that need the fastest links possible for mobile outdoor clients (smartphones, tablets, and laptops) and wireless backhaul. The 1540 Series access points give network operators the flexibility to balance their desired wireless coverage with their need for easy deployment.
Whether deployed as a traditional access point or a wireless mesh access point, the 1540 Series provides the throughput capacity needed for today’s bandwidth-hungry devices.
Featuresandbenefits
By adhering to the 802.11ac Wave 2 standard, the 1540 Series provides a data rate of up to 867 Mbps on the 5-GHz radio. This exceeds the data rates offered by access points that support the 802.11n standard. It also enables a total aggregate dual-radio data rate of up to 1.1 Gbps. This provides the necessary foundation for enterprise and service provider networks to stay ahead of the performance expectations and needs of their wireless users.
In recent years corporate users have increasingly preferred wireless access as the form of network connectivity due to its convenience. With this shift, there is an expectation that wireless should not slow down users’ day-to-day work, but should enable a high-performance experience. The 1540 Series delivers this performance with highly secure and reliable wireless connections for mobile end users.
Table 1 lists the features and benefits of the 1540 Series.
Table 1.Features and benefits of Cisco Aironet 1540 Series
| Feature |
Benefit |
| Compact size |
Enables deployment of the access point where it’s needed. The 1540 Series easily mounts to walls or light poles without disturbing the aesthetics of the area. |
| 802.11ac Wave 2 radio |
Provides up to 867-Mbps data rates with 2 x 2 Multiuser Multiple-Input, Multiple-Output (MU-MIMO) with up to two spatial streams. |
| Multiuser MIMO (MU-MIMO) |
Allows transmission of data to multiple 802.11ac Wave 2-capable clients simultaneously to improve client experience. Prior to the 802.11ac Wave 2 standard, access points could transmit data to only one client at a time, typically referred to as single-user MIMO. |
| Flexible deployment modes |
Allows for deployment in a variety of ways, including as traditional access points and in mesh networks. The access points can also be deployed with the Cisco Mobility Express Solution. This deployment is ideal for small to medium-sized networks that that require 50 or fewer access points without a physical controller. All deployment modes are easy to set up and configure. |
The Cisco Aironet 1540 Series offers the following features:
●Compact, lightweight size: At just over 2.5 pounds (1 kg) and with a small footprint, the 1540 Series is one of the smallest outdoor access points with internal antennas.
●Low power consumption: Achieves full operation on standard 802.3af power (13.9W).
●Integrated antenna options: The 1540 Series offers two models with different antenna patterns to address a variety of use cases.
