@elctrnx_lyf, I don't want to be too breathelss, but I had one executive in the mobile industry speculating in my interview at CES predicting three leading merchant mobile chip companies of the future to be: Qualcomm, MediaTek and Spreadtrum.

What do you think about that?

Yes, Qualcomm needs to watch out. Mediatek is growing and announcing themselves as the new big player worldwide, in addition to already being the dominant force within their region.

thank you Dr Slump and Junko...makes sense...I thought cell phone operators will try to phase out CDMA2000...afterall it is more than 10 years old standard

Mediatek definitely seems to be really ambitiious to get a product like Worldphone SoC into the market soon to win the global smart phone market. They have grown from a basic phone processor maker to be the likes of quallcomm in the last three years. Spectacular !!!

@Dr. Slump, exactly. You explained the issue much better than I did!

Image you are a cellphone company addressing world-wide market. You will prefer a SoC platform can make a common design for all operators or a design missing CDMA operators?(such as Verizon, Sprint, Softbank, China Telecom, and manyothers but small). Yes LTE is the trend but those operators will keep EVDO before they can reach 100% LTE data coverage, keep CDMA voice before VoLTE reach ~100% coverage. That's a long way. And not so many will switch to WCDMA.

If you are as ambitious as MTK in terms of getting into the US market ( and win a socket for Verizon and Sprint), you need CDMA2000 to complete the coverage. It is still relevant.

"Still missing in the radio mix is CDMA2000" - does it really matter? they have W-CDMA which I guess a next gen

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.
