re: Altair attacks Qualcomm, Wi-Fi with low-cost LTE

Like the idea of driving down 4G chip costs. I also wonder, why in the world adding 4G adds ~150$ to device cost. But not sure, about the prospects of a 4G chip without 3G/2G . Most often, your network coverage for 4G is limited. Premium vendors like Apple samsung is unlikely to opt for such a device. If you dont move around much, and lives a area with good 4G coverage. Then it might make sense to get a 20$ 4G chip device vs 150$ 4G/3G/3G chip device.

It seems as though all of this is really riding on cellular providers to adopt this. All of today's newer phones provide LTE. What manufacturer would want a phone that doesn't provide Wifi and 3g too?..

@ntz: Sure eventually (read: ~2018) it becomes widely deployed and lower cost.

I see your point Rick, but don't you think with time LTE becomes cheaper and more available? I guess in a couple of years maybe?

Actually the i500 is available as a stand alone modem to any vendor.

I'd love to read a discussion about whether Wi-Fi, 3G or LTE is the most preferred link of choice for IoT and M2M. I know its horses for courses, but isn't the general hierarchy of preference: Wi-Fi: Cheap and fairly widely available or easily deploy-able 3G: Nearly as cheap if available LTE: Least cheap, least available

@Fire: Good point. Another (potential) competitor. Analysts expect Nvidia eventually will add its Icera modems to its new IP licensing program. But so far, it is not for sale outside Nvidia SoCs.

So why isn't Nvidia with it's i500 mentioned? http://www.nvidia.com/object/i500-cellular-modems-products.html

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.
