Cisco Wireless Release 8.1
PB734449
Overview
The IEEE 802.11ac standard has established Wi-Fi as the primary access network. According to the Cisco Visual
Networking Index
™
forecast, Wi-Fi traffic (53 percent) will exceed wired by 21 percent in 2019. Driven by the
explosive growth of the Internet of Everything (IoE) and the emerging trend of wearable devices, the share of smart
devices and connections as a percentage of the total will increase from 26 percent in 2014 to 54 percent by 2019.
“Wearables” - ranging from smart watches, smart glasses, heads-up displays (HUDs), health and fitness trackers,

“Wearables” - ranging from smart watches, smart glasses, heads-up displays (HUDs), health and fitness trackers,
health monitors, wearable scanners, and navigation devices, as well as “sensors” - have the ability to connect and
communicate with the network using technologies such as Wi-Fi and Bluetooth. These devices will increase
network traffic with application data, OS updates, and security updates in high-density environments such as
college campuses, stadiums, and shopping malls. Advances in technology are being combined with fashion to
match personal styles, along with network improvements and the use of analytics and monetization systems, such
as location-based services.

Wireless Release 8.1 delivers technological innovations to help customers and partners adapt to these
advancements in technology and meet the challenges associated with these emerging trends. This software
release enhances Cisco High Density Experience (HDX) complemented by new 802.11ac wave 2 optimized
wireless controllers. This release also enables support for highly accurate and innovative location technologies,
and delivers best practices to help alleviate the complexity of managing networks with more clients, bandwidth-
hungry applications, and high-density network strain to provide an enhanced customer experience on Wi-Fi
networks.
Primary Features in Release 8.1
●
Cisco Enhanced HDX: New enhancements to the HDX suite include the following:
◦
Dynamic bandwidth selection (DBS) with flexible dynamic frequency selection (FlexDFS) simplifies
and automates the configuration of channel width to enable greater operator confidence in using a wider
channel bandwidth while reducing radio flapping and optimizing spectrum efficiency
◦
Airtime fairness provides a simple way for WLAN administrators to allocate usage to groups of clients
◦
Optimized roaming extensions add 802.11v BSS Transition Management to optimized roaming to
enable the infrastructure to provide explicit advice to clients for reassociation and roaming
●
Hyperlocation with Advanced Security enables microlocation accuracy to better serve hyperlocal
content, with more frequent location updates for Wi-Fi clients using Cisco Connected Mobile Experiences
(CMX) FastLocate. Bluetooth Low Energy (BLE) services, including integrated BLE beacons, simplify
beacon management. Advanced Security enables security threat detection and mitigation on 802.11ac
networks
●
WLAN express and best practices on wireless LAN controllers (WLCs) enable simplified operations
and enhanced performance, security, and resiliency with best practice recommendations turned on at
bootup
