"Strauss said he does not expect LTE chips for handsets before late 2012." What about the Samsung Craft which I read somewhere uses a Qualcom chipset?

what about Sequans, isn't their wimax chip in the HTC 4G phone? Also, these chip suppliers will be in CMCC TD-LTE dongles: 1. Samsung 2. Innofidei 3. Sequans 4. ST-E (T3G)

Hi, SDR looks interesting. I have been working on SDR for quite sometime now. I would like to work on 4G LTE,anyone interested for this ? contact me: sudar_ns@yahoo.com sudarshan@spacomp.com

Well, Rick Merritt got it right, its only a matter of time. Until that time CEVA and others can make their noise. And to DaveKelf: "The real question is the efficiency of device programming, as an effective software implementation can make an order of magnitude difference in performance." How will make c-like code to compete with AND/OR/XOR gates? Well as you said that's the real question and I personally don't think today's solutions have an answer!

It is clear that these new vector processors have greatly narrowed the gap between custom hardware and programmable devices in terms of power consumption. The real question is the efficiency of device programming, as an effective software implementation can make an order of magnitude difference in performance. Leading companies are finding that this is the significant issue to solve, and when they do, custom hardware basebands may well become obsolete.

True that SDR will reduce R&D cost, time to market, and tapeout risk. If you want a fast product and functional unit, SDR may be the way to go. But for very few companies who know how to do it right, hardwired solutions will yield astonishing low-cost low-power solutions with surprising high performance which is not possible given the current power of DSPs. The market will be lose or get-it-all.

That may be so; but the point here is that there are already so many permutations of 2G/3G implementation -- depending on cellular network providers and depending on different parts of the world. LTE being the first truly global standard, SDR may be just the way to go, not just as an interim solution, but as a long-term solution. At least, that was the sense I got talking to CEVA's CEO.

IMHO, CEVA has a good opportunity selling programmable chips in this transition when no what quite knows what a 4G handset should be, but by 2011-2012 when the system design gets more clearly defined dedicated chips will emerge and win the day as most cost effective.
