5G in the EnterpriseWhat providers are saying

5#ArubaAirheads

Provider:5G will provide better coverage – starting with urban areas

1.500 5G-Antennas for Germany until end of 2020

LTE as basis for 5G

Telekom will bring 5G in all 16 state capitals in Germany in 2020

https://www.telekom.com/de/medien/medieninformationen/detail/telekom-bei-5g-im-plan--587232

6#ArubaAirheads

Provider: 5G will offer revolutionary speed

Faster speeds (1Gbps+) are why carriers are positioning 5G everywhere

Caveat: Speed comes at the expense of coverage and signal penetration

Nodes are required every 100m – 200m to provide 96% of LTE coverage

https://www.theverge.com/2019/9/19/20873652/verizon-5g-new-york-city-manhattan-brooklyn-bronx-queens

https://www.lightreading.com/mobile/5g/5g-the-density-question-/a/d-id/740634

7#ArubaAirheads

Provider: 5G will unlock AR/VR, automated cars, telemedicine, and connected buildings

Cellular continues to be ideal for wide area, high mobile requirements

Use cases are limited in dense, urban areas –especially in the near-term

Rural areas will rely on broadband or existing cell coverage

8#ArubaAirheads

Provider: 5G will handle massive device connectivity

Cellular is used in IoT use cases today – and 5G will expand what’s possible

Full 5G benefits will draws more power – so IoT use cases will be limited by device capabilities

9#ArubaAirheads

Provider: 5G will be ultra-reliable and provide better capacity

Like Aruba Live Upgrades, 5G networks are meant to prevent outages

In 2020 or later, network slicing will deliver performance guarantees

This is similar to Aruba Air Slice, which debuts in ArubaOS 8.6

https://www.fiercewireless.com/wireless/at-t-verizon-gear-up-for-5g-network-slicing-2020-2021-timeframe

10#ArubaAirheads

Provider: 5G will be ultra-low latency

Like Wi-Fi 6, 5G is delivering low-latency using techniques like OFDMA

OFDMA is a more efficient way of consuming radio resources

Like Aruba Air Slice, network slicing also plays a role in low-latency uses

11#ArubaAirheads

What’s the Reality?5G has a place – and so does Wi-Fi

12#ArubaAirheads

Primer on Wi-Fi 6, 5G and Campus NetworksThere’s a lot of hype, so guide your customers on their journey

5G and Campus Networks

–5G is very early, expensive, carrier-specific and different in-building

–5G campus network are expensive and subject to the same physics as Wi-Fi.

–The marketing spend is massive as carriers seek to gain new market share

Wi-Fi 6 serves as the onramp to 5G

13#ArubaAirheads

Inconsistent Carrier Experiences

5G service is based on carrier and geographic availability

5G is marketed as blazing fast – but is a mix of high, mid, and low band frequencies

T-Mobile Competitive Campaign against Verizon’s 5G availability

14#ArubaAirheads

Cost is a Major Factor

5G devices are more expensive

Cell plans are required for every device – and may be an extra charge

A lot of small cells will be needed

15#ArubaAirheads

In-Building Cellular Coverage Issues

~75% of mobile traffic will be video in 2024 (Ericsson)

Up to 90% of mobile data is generated indoors (Gartner)

Some carriers are focusing on the outdoors only

“mmWave does not propagate well in buildings with concrete, or brick, walls, and covered in [low-e] glass windows” – Nokia Bell Labs

16#ArubaAirheads

In-Building Cellular Coverage Issues

Wi-Fi is designed specifically for indoor coverage

5G/CBRS abide by the same physics as Wi-Fi indoors

Enterprise guest access remains a persistent issue

“mmWave does not propagate well in buildings with concrete, or brick, walls, and covered in [low-e] glass windows” – Nokia Bell Labs

17#ArubaAirheads

High Density Issues in Large Public Venues

Cellular networks traditionally don’t perform well in crowded areas

5G and Wi-Fi 6 are both designed for high density

They use similar technologies

OFDMA(uplink and downlink) and MU-MIMO (downlink)

802.11ax Key Features

OFDMA

MU-MIMO

OFDMA increases capacity

OFDMA reduces latency for voice and IoT

Ideal for low bandwidth , small packets ( voice

and IoT), latency sensitive applications

MU-MIMO increases capacity

MU-MIMO results in higher speed and

throughput per user – transmit to up to 8 clients

Ideal for higher bandwidth applications such as

HD Video or large files

Congestion and delay

22#ArubaAirheads

802.11ax Key FeaturesOrthogonal Frequency Division Multiple Access (OFDMA)

– With OFDMA, variable numbers of subcarriers can be grouped and allocated for multiple individual AP-client pairs

– These groups are called Resources Units (RU) and can be (roughly) 2MHz, 4MHz, 8MHz, 20MHz, 40MHz or 80MHz wide in varying mixes.

Usable tones

26 tone RUs (~2 MHz),37 max RUs

52 tone (~4 MHz), and 26 tone RUs

106 tone (~8 MHz) and 26 tone RUs

242 tone RUs (~20 MHz) and 26 tone RU

484 tone RUs (~40 MHz) and 26 tone RU

Non-OFDMA996 tone (~80 MHz)

7 DC NullsFor OFDMA

5 DC Nulls for Non-OFDMA

23#ArubaAirheads

802.11ax Key FeaturesSpatial Reuse or BSS Coloring

– BSS Coloring was a mechanism introduced in 802.11ah to assign a different “color” per BSS, which will be extended to 802.11ax

– Client “learns” color from its AP/BSS

– The traditional -82dBm threshold will be used when the colors match

– When the colors don’t match, a higher threshold can be used

– Other devices are known to be close, so it’s not surprising to “hear” them. No need to be overly quiet

– Actual threshold is dynamic, and could be as high as -62dBm

– Transmit power of the device factors into the threshold level

– If a device lowers its power, it can transmit more aggressively

32#ArubaAirheads

Aruba Enterprise Passpoint InitiativeSummary

• Enable Passpoint discovery and authentication as a standard feature of enterprise Wi-Fi

• Solve cellular coverage and guest access problems for enterprise customers

• Enhance security and business analytics by providing visibility of all local traffic

• Obviate perceived need for small cells (LTE, LAA or 5G), DAS, and private LTE/5G Campus networks

• Allow operator access to Wi-Fi footprint accessible on terms favorable to the enterprise

• Create a framework for enterprise roaming consortia independent of mobile network operators

• Lay foundation for enterprise Wi-Fi to become principal on-ramp to future 5G network services

33#ArubaAirheads

What does all this mean to you now?

• 5G is a business agenda driven by service providers and IoT/Industry 4.0 use cases

• Technology wise Wi-Fi 6 & 5G radio technology have converged and complement each other

• Deutsche Telekom: “WLAN will continue to play an important role for many industrial applications in the future. But LTE, and in the future 5G, will complement the WLAN networks for even better, above all reliable connectivity.” (https://www.telekom.com/en/company/details/5g-technology-in-campus-networks-556692)

• 5G core network architecture has been decoupled from 5G radio, potentially allowing Wi-Fi 6 to become the enterprise on-ramp to 5G networks and services

• Wi-Fi 6 supports a robust, high capacity, and inherently neutral host ecosystem with backward compatibility under enterprise control

• Wi-Fi 6 is available today and Aruba’s approach to Wi-Fi/5G integration positions enterprises to determine the terms of their future relationships with 5G operators and their services

34#ArubaAirheads

Status of Wi-Fi 6 and 5G convergence

• Passpoint/Hotspot 2.0 is a requirement of the WiFi4EU(https://ec.europa.eu/digital-single-market/en/wifi4eu-questions-and-answers)

• Large public customers see the benefit but service provider support is required for the business model to work

• As of today service providers in Germany are not pushing Passpoint profiles to their subscribers but that may change soon

• Wi-Fi is “The ultimate hidden hero”https://bit.ly/2CAD1Fl
