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
