Support for two key technologies differentiates the APs selected for deployment in the campus WLAN:
● 
802.11ax (Wi-Fi 6)
—The IEEE 802.11ax (Wi-Fi 6) specification provides for significant enhancements to 
wireless networking performance including the following: 
◦
Higher capacity: Attach more devices than under previous standards through features such as 
orthogonal frequency-division multiple access (OFDMA) and multiuser multiple-input multiple-output 
(MU-MIMO). Wi-Fi 6 communicates in parallel with devices, whereas existing standards communicated 
only "one at a time".
◦
Improved power efficiency: Using target wake time (TWT), client devices that support the Wi-Fi 6 
standard may consume less power. This means that batteries in products such as smartphones, 
laptops, tablets, and IoT devices can last longer, which makes it the ideal standard.
◦
Reduced data latency by optimizing packet scheduling, which is ideal for voice, video and gaming 
applications. 
◦
Greater IoT coverage by bringing the benefits of Wi-Fi 6 to the 2.4- GHz band. 
◦
Increased speed: Gain an increase in average throughput in congested wireless environments. 
◦
Improved security: WPA3 is certified with Wi-Fi 6 and provides a greater value proposition than WPA2 
for enterprise Wi-Fi networks. It offers enhanced security for open Wi-Fi networks with encryption of 
unauthenticated traffic, robust password protection against brute-force dictionary attacks, and superior 
data reliability for sensitive information with 192-bit encryption. 
● 
Cisco RF ASIC
—The custom Cisco RF ASIC, available within the Cisco Catalyst 9120AX and 9130AX 
Series APs, provides enhanced off-channel monitoring, improving serving radio performance by as much 
as 25 percent, as well as Flexible Radio Assignment (FRA), CleanAir, wireless intrusion prevention system 
(WIPS) and DFS detection. This silicon-level intelligence creates a self-healing, self-optimizing wireless 
network that mitigates the impact of wireless interference.
