Featuresandbenefits
By adhering to the 802.11ac Wave 2 معيار, ال 1540 Series provides a data rate of up to 867 ميغابت في الثانية على الراديو 5 جيجا هرتز. 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 جيجابت في الثانية. 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. ال 1540 Series delivers this performance with highly secure and reliable wireless connections for mobile end users.

| ميزة | Benefit |
| Compact size | Enables deployment of the access point where it’s needed. ال 1540 Series easily mounts to walls or light poles without disturbing the aesthetics of the area. |
| 802.11موجة التيار المتردد 2 راديو | Provides up to 867-Mbps data rates with 2 x 2 Multiuser Multiple-Input, Multiple-Output (مو ميمو) with up to two spatial streams. |
| Multiuser MIMO (مو ميمو) | Allows transmission of data to multiple 802.11ac Wave 2-capable clients simultaneously to improve client experience. Prior to the 802.11ac Wave 2 معيار, 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 كلغ) and with a small footprint, ال 1540 Series is one of the smallest outdoor access points with internal antennas.
●Low power consumption: Achieves full operation on standard 802.3af power (13.9دبليو).
●Integrated antenna options: ال 1540 Series offers two models with different antenna patterns to address a variety of use cases.
