Very few companies can put multiple radios on a CMOS chip so contention that Broadcom and Qualcomm will dominate that market is not surprising...but 5 billion number is...if ASP is say $10 that would create $50B market for wireless chips, sounds too high...Kris

5B wireless connectivity chips with 5 different types - Bluetooth, Wi-Fi, satellite positioning, near-field communications and ZigBee. If an assumption of putting each into a smart device including smartphone, tablet and laptop computer, 1B units of all these 3 devices doesn't sound ridiculously high. Nonetheless, will there be so many high end devices sold in 2013?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
