“Standards” challenges“Standards” challenges

Often more recommendations than standards Drafted as a compromise between actors with

different (opposing) interests Leave a lot of room for interpretation

Standards competing against each other

Of all Telco standards, those involving SIM & devices have the most complex lifecycle

Standard compliant systems often become

disguised proprietary systems

Ensure seamless “out of the box” experience for-end users

Focus on device/SIM communication / Near field tests

Identify problems before device & SIM is in user hands

Key selling proposition for all vendors (win/win)

Focus on cohabitation and reuse of other embedded

software

Test “borderline cases” linked to Hardware / Software

Need support from Hardware vendors (developer programs)

Focus on client/server IOT for management of the device/SIM

Identify build DB of device & SIM specificities

Critical part as the OTA server allows bypassing limitations

Plug tests should become permanent

Focus on management of the software agent after device is in

user hands

Step out of proprietary end to end solutions

Allow cross-selling opportunities for both vendors
