14 FAQs
What is 802.11ax?
The IEEE 802.11ax standard, also known as the High-Efficiency Wireless (HEW) or Wi-Fi 6, builds off of the 802.11ac
and delivers a better experience in typical environments, and a more predictable performance for advanced applications
such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and
Internet-of-Things (IoT). 802.11ax is designed to use both 2.4Ghz and the 5GHz bands, unlike prior standards.
What is Flexible Radio Assignment?
The Flexible Radio Assignment (FRA) feature automatically detects when a high number of devices are connected to a
network and changes the dual radios in the access point from 2.4 GHz/5 GHz to 5 GHz/5 GHz to serve more clients. The
access point performs this function while still monitoring the network for security threats and RF Interference that may
affect performance. Flexible Radio Assignment improves mobile user experience for high-density networks.
FRA has the different modes of operation:
•Default operating mode—Serving Clients on both 2.4 GHz and 5 GHz
•Dual 5 GHz Mode—Serving clients on both 5 GHz Radios
•Wireless Security Monitoring—Scanning both 2.4 GHz and 5 GHz for security threats while also serving 5 GHz clients
What is a Smart Antenna connector?
The C9130AXE model has a Smart antenna connector (see Figure 13), which is connected directly to the flexible radio.
Without a supported external antenna connected to the Smart Antenna connector, the flexible radio can stay only in
2.4 GHz mode. If an external antenna is connected, the flexible radio can be used in the full Flexible Radio Assignment
mode, allowing dual 5 GHz and Wireless Security Monitoring modes.
To connect to any supported RP-TNC connector-type external antenna to the Smart antenna connector, use the DART
cable connector AIR-CAB002-DART-R= (see Figure 14), which is to be procured separately from Cisco.
