802.11ax Key Features

11/12/2019 Cambium Networks Ltd, 2019 6

802.11ax will focus on improving the connected client experience by making the

network more efficient

Downlink Multi-User OFDMA and MIMO

11/12/2019 Cambium Networks Ltd, 2019 7

Allocates Resource Units as small as 2MHz

Benefit: Reduced Latency, efficient use of time and frequency

Ideal for: VoWLAN, IOT devices, always-connected mobile devices

Stadiums, Higher Education, Hotels, Enterprise

Transmit to multiple devices at the same time

Benefit: high capacity with high bitrate

Ideal for: Streaming media, high bitrate applications, stationary PCs

Higher Education, Hotel Conference center, Enterprise

OFDMA MU-MIMO

2MHz RU

up to 4 MU

Uplink Multi-User OFDMA and MIMO

11/12/2019 Cambium Networks Ltd, 2019 8

Increase reverse-path range of multiple low power clients

Increase uplink datarate, reduce latencyGreat for gaming, high density social media

OFDMA MU-MIMO

2MHz RU

up to 4 MU

Up to 4.8Gbps PHY rate, combined, bi-directionalGreater combined SNR = improved range

Other 802.11ax key technology

1024 QAM• 30% topline speed improvement over 11ac. Works with 11ac clients and 11ax

Spatial Reuse (BSS Coloring)• Allows multiple BSS (AP + its connected clients) to overlap in same frequency

Preamble Boost and sub-carrier repetition• 3dB power boost increases range outdoor, increased GI improves resilience

Target Wait Time• Sleep time negotiated by AP and Client• Longer battery life for mobile devices even while streaming media, extended IOT life

2.4GHz band• Extend AX capabilities to new bands (2.4GHz and planned 6GHz)• Ideal for IOT devices with low bitrate requirements

Pre-standard 11ax access points lack key features, not software upgradable to all features, expensive, and there is no way to test

As stated by Gartner, ensure the solution supports critical features and is software upgradable to final standard and new features
