AIR-RM21A-A-K9=

The Cisco Aironet 802.11a Radio Module, part number AIR-RM21A-A-K9=, is designed to extend wireless functionality in Cisco Aironet devices. This module supports 802.11a wireless networking, offering up to 54 Mbps wireless transmission speeds in the 5 GHz frequency band. It's well-suited for high-bandwidth applications, providing reduced interference compared to the 2.4 GHz band, which is often more congested.

With this module, users add advanced functionality to compatible Cisco Aironet access points, enabling fast, stable wireless communication. The use of the 5 GHz spectrum allows better support for dense wireless environments, as this band has a larger number of non-overlapping channels, ideal for those requiring high-speed data transfers across multiple users.

This network adapter is designed for businesses or larger organisations using wireless local area networks (WLAN) and provides the reliability and performance businesses expect from Cisco products. In terms of form factor, this is a modular component that integrates seamlessly into select access point models, enhancing coverage and network performance without requiring a full system upgrade.

The module works well in data-sensitive scenarios such as voice-over-IP (VoIP) applications, video streaming, or any deployment areas that demand high throughput with minimal interference. It is simple to add and configure according to your wireless network needs, thanks to Cisco's plug-and-play installation approach, allowing IT departments to quickly boost network capabilities in existing setups.
