4G traffic set bottle neck
(2.5GB)，unlimited traffic
Corner point 2:
3G traffic bottleneck
(500M)  4G
Revenue
Corner point 4:
Option 1: new killer apps are
traffic hungry？
Corner point 1:

Option 2: from traffic oriented
to connection oriented ？
Japan is here

Major trends of wearable products
• Wearable device is a mobile phone accessory
wearable worn in-clothing or on-body or
standalone wearable (12% market share).
* Huawei’s analysis
• Wearable devices are focusing on fitness and
wellness (60% market share), Healthcare and
Medical, Infotainment.

Dirty secret of wearable
Nowadays wearable devices are lack of user loyalty

What distinguishes wearables from others?
• Form factor limitations




Small enough to wear → size limits on battery, antenna, screen, PA…
User expectations: A watch should look like a watch
Unlikely to support multiple radios
Cost concerns may impose various limits (not all device types)
• Proximity to user’s other devices


Wearables may come in clusters (watch, glasses, fitness band for the same user)
User typically has a phone as well
• Different service mix compared to a smartphone


Specialised data services (e.g. fitness band, medical devices, industrial workplace sensors)
Often low data rate, small packets


(but not always; e.g. glasses sending a video stream)
Voice support: sometimes, but not a primary use

Wearable interacts with local devices
Wearable is typical a cell phone accessory
Size and battery limitation makes always cellular
connection impossible (50~300mAh)
Power consumption is one of the top reasons for
wearable costumer loss
Typically, communication consumes 20~40%
power for band and watch
1) Battery is top concern for wearable devices

Standalone wearables
Case 3: 5% wearable
are for Children and
older who do not how
to use smart phone
Case 1: Up to 15% of
time in a day, cell
phone is inconvenience
or unavailable
Case 2: Health, medical and
tracking related scenario
40% users expect wearable to be
independent to cell phone – by Tencent 2015
report
2) Anytime, anywhere and anyone connection is rigid demand

Security and privacy are concerned
•
BLE/WiFi protocol stack end at UE. This makes wearable device and
data open to the OS and APP

•
•
Lack of interoperability
Wearable is unknown to network

•
Application layer security guaranteed is too heavy.
Hard to detect attack
User experience of BLE/WiFi security is not good.

Wifi master key, BLE is implementation dependent
WAN
Barnaby Jack died a week before his presentation on
hacking heart implants at the Black Hat 2013
conference.
• Data security: Mobile pay, health, medical, location information
• Device security: wearable usually linked to address book
3) WiFi/BLE connections at smart phone are sweet points for security attack

Wearable are dominated by OTT
• Wearable penetration is in early adoption area


Wearable can both generate and consume content and therefore can bring
more connections to MNO.
In the future, wearable are expected to take up to 40% functions of cell phone
• Wearable connection are mainly BLE and WiFi. The apps are developed
by OTT.


MNOs are bypassed and have no revenue from wearable
WiFi and BLE camp are in motion
• If wearable are solved by IT solution instead of 3GPP, the whole 3GPP
ecosystem will face more challenge in long term.

Will that happen?

Wearable air interface is NB-IoT evolution
Benefits
WAN

Higher data rate for extended coverage scenario

E-E manageable wearable device

Flexible network topology to allow more services, e.g.
iBeacon services
1) Low power cellular link

Flexible combination of direct link and short range NBD2D link
(CIoT as baseline)

Higher network spectrum efficiency
2) Ultra-low Power NB-D2D link
(new D2D function of CIoT)

Scenarios for wearable communications
•
•
Connectivity is a crucial issue

Direct connection to network

Connection to the network through a relay UE

Short range communication among devices, with a “gateway” link

Local mesh network among WD (and perhaps other) devices

A hub or UE provides backhaul to the network
Flexibility is important

The WD should switch between connection modes without disruption to the
user

Support intelligent decisions about which mode is chosen

Many short range options are available: Bluetooth, 3GPP D2D, WiFi Direct;
licensed or unlicensed band; autonomous resource decision or network
controlled

3GPP wearable device standard status
•
Currently, 3GPP are developing service requirements for wearables as part of 5G
standardisation
•
•

Wearables are seen as an aspect of massive IoT, which is a major early component of 5G

High level service requirements are approaching completion in 3GPP SA1 working group

Feature and architectural specification work to start Q2 2016
5G timeline has commercial deployment in 2018-2020

But the market is rising now; 2018-2020 is too late

So, support should be available sooner, as part of LTE evolution

Huawei and other 3GPP companies are collaborating to launch such an effort

Work could start Q2 2016

Similar start time to 5G work, but time to deployment can be much shorter
Current objectives could support all scenarios described above

Discussion is still in progress and conclusions cannot be certain yet

Conclusions
• Wearable devices are a large, fast developing area of the market

Already a significant revenue sector

Likely to become a very large revenue sector quickly
• We are pursuing different technologies in parallel

3GPP 5G already providing service-level requirements

Working to add support in LTE, based on the 5G directions
• Coordinate the technologies invisibly, let the user see a service

Common technical challenges for all involved standards

Driving towards architectures that support smooth integration
