Increased Revenues from Obsolete Technologies
DrQuine   3/14/2014 5:55:17 PM
NO RATINGS
I fear the substantial increase in wireless charging revenues will be from the purchase and disposal of multiple charging solutions. I'd like an agreed upon standard to be developed and deployed so that we don't all fill up our attics with obsolete "technologies of the year". As it is, I see history repeating itself. No sooner did we eliminate the proliferation of incompatible connectors than we are moving to incompatible wireless charging solutuons. Will we never learn?

Re: please fix the math.... there is no 40 fold growth

I agree, while "40-fold" may evoke images of multiple "folds" of paper, 40-fold simply means 40 times (which is still plenty).

Any info on the size of the receiver?

I'm interested in how much room a wireless charging receiver will need. Anyone know what it takes? Can it easily fit into a ring or wrist band?

Good point. There needs to be a new approach to the way we think about developing this technology. Three brands presented here, and two of them are quite mutually individuated processes for carrying out (in essence) the same function.

We will obviously need at least several different suppliers for MRP transfer--otherwise monopolies are going to ruin the advancement of this technology. Competition between companies will drive the advances in the efficiency of the products themselves, but damn can't we at least standardize the basic electromagnetics used to operate these devices? Seriously, we're delaying the accessibility and usage of this technology AND suppressing hopes for making some critical progress in that technology by making a bunch of different frameworks for the same sh*t. 

I'm probably overhyping my point of view, but come on...who is going to want to buy a ton of different types of wireless chargers unless they have to. Cross-platform compatibility is just as important to implement as is wireless systems for charging devices.

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.
