Background
IOT Device interoperability
Locally: IOT devices work with
phones, tablets, PCs
Remotely: many applications can
make use of the same device
(and data on that device)
M2M vs IOT
Standard
protocols
IOT 1
Delivers the vision of devices working with each other.
Wide application interoperability

How does it work
Open source IOT platform. Open
ecosystem, cheap device
development
Cloud asset management
platform. Control of cloud
agents and processing resources
Multi device application
development platform. Bring IOT
data to life
An Open and Secure End2End IOT platform
