The Cisco Aironet 802.11g Access Point Upgrade Kit (Part Number: AIR-MP21G-E-K9=) is a network adapter designed to enhance wireless network performance by upgrading existing Cisco Aironet access points to support the 802.11g wireless standard. This upgrade kit is compatible with specific models of the Cisco Aironet series, allowing organisations to achieve faster wireless speeds while maintaining backward compatibility with 802.11b devices.
The kit includes a card containing the 802.11g radio, which offers improved data rates of up to 54 Mbps, over the slower 802.11b standard that supports just 11 Mbps. This provides a significant boost in wireless transmission, increasing efficiency and throughput for a wide range of applications, from basic data communication to multimedia streaming. It operates within the 2.4 GHz frequency band, making it suitable for connecting various wireless devices without requiring new infrastructure. Moreover, it supports OFDM (Orthogonal Frequency Division Multiplexing) modulation, which boosts the overall signal efficiency and reliability, particularly in environments with dense network traffic or interference.
The Cisco Aironet 802.11g Access Point Upgrade Kit comes equipped with WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access 2) encryption technologies, providing robust security protocols to protect sensitive data transmitted over the wireless network. This ensures compliance with industry standards, safeguarding enterprise IT environments. Furthermore, the device supports wireless roaming, ensuring that users maintain strong connectivity even when moving between access points. This feature makes it ideal for large areas such as campuses, warehouses, and office complexes that require reliable unbroken network coverage.
With this upgrade kit, organisations can maximise their existing infrastructure while enjoying enhanced security, improved data rates, and seamless network integration across different wireless standards.
