M2M Market and IoT Background

M2M demand plus new applications creates rapid growth

In China, M2M market is driven in part by government funding in Internet of Things (a.k.a. IoT).

• Based on M2M, IoT is a network that connects any object

• China telecom operators strategy in M2M

– cdma2000 proved adequate for embedded mobile M2M, and EV-DO networks in particular are capable of higher bandwidth connections

– China Telecom Mega Eyes System

Emerging tech

Real network simulation in test lab

Signal analysis with higher modulation requires better EVM performance.

Analyzing wider bandwidth signals up to 100 MHz in emerging technology

RF engineers need visibility into the protocol layer to understand why RF test is not behaving as expected

Measuring multiple signals simultaneously and interference between each other

Higher order MIMO test set up requires more time, effort and cost

Moving to higher frequencies





Test Challenges & System-level Solution

Test Challenges System-level Test Solution

Find out the product problem as early as design phase

Combining simulation and measurement together allows for complex systems

Numerous viable applications have different test standard and requirements

Distinguish sensor/network layers from application layer and ensure stable L1/L2 ahead of application design phase

Multi-standard networks complexity growing exponentially

Next generation technologies for…• Higher Data Rate• Better Spectrum Efficiency

Providing wider bandwidth analysis, higher modulation and simultaneous verification of RF layer and protocol layer

Co-existence of next generation and legacy wireless systems

Delivering Multi-Standard in one box solution that simplify design and test of different systems

More Antennas to improve wireless system performance

Measurements up to 8 channels and resolving the different results from conducted test and field test performance with MIMO OTA

“From Design to Test” – System-level Solution on Internet of Things
