Wi-Fi 6 (802.11ax)

The IEEE 802.11ax emerging standard, also known as High-Efficiency Wireless

(HEW) or Wi-Fi 6, builds on 802.11ac. It delivers a better experience in typical

environments with more predictable performance for advanced applications such as

4K or 8K video, high-density, high-definition collaboration apps, all-wireless offices,

and IoT. Wi-Fi 6 is designed to use both the 2.4-GHz and 5-GHz bands, unlike the

802.11ac standard.

Uplink/downlink OFDMA

Orthogonal Frequency-Division Multiple Access (OFDMA)-based scheduling splits

the bandwidth into smaller frequency allocations called Resource Units (RUs), which

can be assigned to individual clients in both the downlink and uplink directions to

reduce overhead and latency.

Uplink/downlink MU-MIMO

technology

Supporting four spatial streams, Multiuser Multiple-Input Multiple-Output (MU-MIMO)

enables access points to split spatial streams between client devices to maximize

throughput.

BSS coloring

Spatial reuse (also known as Basic Service Set [BSS] coloring) allows the access

points and their clients to differentiate between BSSs, thus permitting more

simultaneous transmissions.

Target Wake Time

A new power-saving mode called Target Wake Time (TWT) allows the client to stay

asleep and to wake up only at prescheduled (target) times to exchange data with the

access point. This offers significant energy savings for battery-operated devices, up

to 3 to 4 times the savings achieved by 802.11n and 802.11ac.

Cisco RF ASIC

Cisco RF ASIC is a fully integrated Software-Defined Radio (SDR) that can perform

advanced RF spectrum analysis and delivers features such as Cisco CleanAir,

Wireless Intrusion Prevention System (wIPS), FastLocate, and Dynamic Frequency

Selection (DFS).

Bluetooth 5

Integrated Bluetooth Low Energy (BLE) 5 radio enables location-based use cases

such as asset tracking, wayfinding, and analytics.

Multigigabit Ethernet support

Provides uplink speeds of 2.5G, 1G, and 100M. All speeds are supported on

Category 5e cabling for an industry first, as well as 10GBASE-T (IEEE 802.3bz)

cabling.
