WHAT’S COMING?


At the end of 2013

there were more

mobile devices

than people on

earth - SAP

“ “

By 2020, it is

predicted that 24

Billion devices will

be connected to

the Internet. The

vast majority will

use some form of

wireless for access - GIGACOM

“ “

Wi-Fi Predictions

Number of client devices that were NEVER connected

before is expected to grow exponentially and is becoming

GREATER than number of existing devices

What Does It All Mean?

1.3Gbps

3.5Gbps

802.11ac Channels


Wider channels support higher data rates

• Double the channel width from 40 MHz to 80 MHz and the data rates double

The 802.11ac standard requires first-wave products to support 80

MHz channels

• But that does not mean that it is mandatory to use them!

Subsequent products may support up to 160 MHz channels

• But is that even feasible?

New Proposed U-NII Bands & Channels


U-NII-1(100 MHz)

U-NII-2A(100 MHz)

U-NII-2C(255 MHz)

New BandU-NII-2B

(120 MHz)

New BandU-NII-4

U-NII-3(125 MHz)

5.150 GHz 5.250 GHz 5.350 GHz 5.470 GHz 5.725 GHz 5.85 GHz 5.925 GHz

Transmit Beamforming & MU-MIMO


SU-MIMO directs energy to a single device

MU-MIMO transmits independent streams to multiple devices

Beamforming steers an individual stream to one receiver

Less Network Congestion


Faster 802.11ac speeds means less congestion & less time to

transmit data

• Less Layer 2 overhead means less congestion time

• Better use of medium contention when MU-MIMO becomes more prevalent

Less congestion equates to better use of the shared medium

• Not only by 802.11ac clients but 802.11a/n clients as well

802.11ac Wave 2 Challenges: Clients


There are only 4 consumer devices that partially support Wave 2!

• Even next generation client devices will most likely lack 160 MHz channels and 4 spatial stream support

In order to reap the benefits of Wave 2 and get a 33%

performance boost, the client device NEEDS 4 spatial stream antenna

• Not only by 802.11ac clients but 802.11a/n clients as well

Wave 1 or Wave 2?


Check organizational needs first

• Even next generation client devices will most likely lack 160 MHz channels and 4 spatial stream support

What’s Next


Tiny Bluetooth device that

sends out a location ID

› Can be standalone or partof a bigger device (computer,phone, tablet)

Triggers an action on mobiledevices

› “Welcome to Aerohive HQ!”

Transmissions are separate fromWi-Fi (but still use 2.4 GHz)

What is an iBeacon?

Location

› Absolute

› Coordinate system

Proximity

› Relative position/motion

› No coordinates needed

› No mapping of physical space to contents

iBeacons use Proximity

Proximity is NOT location!!!!


Interact with the world around you!

Many applications

› Queue management (retail)

› Mapping

› Guides

› Games

› What it does is limited only byyour imagination

Low cost makes it easy to havelarge numbers of iBeacons

What can you do with an iBeacon?

2016 & Beyond



• Target: Low power/extended range/low data rate

› Meter and sensor control & data

› Extended range requirements (~900 MHz has longer range)

• Possible applications: utility meters, HVAC, alarms, lighting

control, temperature/air sensors, location tags…

• In addition to low power, special features for IoT-type applications (high numbers of devices, but low bandwidth)

802.11ahSub 1 Ghz

Tentative spectral map (per geography)


Standard being developed for highdensity deployments (both AP &client)

Goal: increase throughput by 4x› Efficiency gains, not speed gains

› Target is average per-station throughput,not total network throughput

Overlay on older 2.4 GHz and 5 GHz PHYs (802.11a/b/g/n/ac) –compatible with older technology› Experimental results: 5-10x gain

Timeline: Estimate Draft 2.0 in 2017?
