Three Major Challenges to IoT
Profit Model through Data
Analysis
From Individual to Eco-system
BUSINESS MODEL SECURITY
Web transfer
Content Protection
ID
Security
Transaction Safety
1. Software & hardware companies collaborating on security standards
2. New security system (ex: biometric system)
1. Define profit models
to extract value from IoT
2. Build eco-system to hasten cross-industry cooperation

When is power management important?
10
It should always should be considered a crucial feature • Alongside areas such
as security • Even if the scenario
doesn’t appear to require careful power management
• Not just for items such as wearables or smartphones
Copyright © MediaTek Inc. All rights reserved. 11
MediaTek’s focus MediaTek has legacy of low-
power, small footprint solutions • Existing solutions in the LinkIt
portfolio have class-leading low-power capabilities
• Pioneering use of multi-mode options
MediaTek continues to focus on low-power, high performance New SoCs such as the MT2523 and
MT7687 include PMU support
12
Identifying power saving opportunities
Need to identify all possible behaviors • Use-case modelling • Likely areas of compromise vs non-
negotiable behavior
Power mode flows • Including transitions from one-state to
another
Connectivity • Which protocol best suits usage? • Always-on?
