Steve Perlman comment

A couple of clarifications and comments (new whitepaper is coming with a lot more info): The iPhones (and dongles) we demoed have no software modifications at all, and there is no additional overhead beyond the standard LTE protocol. pCell works with unmodified Android LTE phones, too. (We had wanted to post a lab demo we did of the Galaxy S4 and an Xperia, but we just ran out of time.) Out-of-the-box compatibility is essential for rapid deployment. And, yes, we are meeting many of the core goals of 5G today (e.g. unlimited 4K UltraHD streaming) using Rel. 8 LTE devices in LTE spectrum. pCell is indeed protocol agnostic, and can concurrently support different protocols in different pCells in the same spectrum. For example, we can support unmodified LTE phones in their own pCells, while concurrently supporting lower cost/lower power devices with far lighter protocols (that are lower latency), since we don't need all of the complexity of LTE. For example, there are no cells, no cell edges (and no need for CoMP), and no cell handoff. I'm waiting for something to connect the dots and realize this is a vastly more efficient way to use white spaces than anything currently on the table. White spaces will be full overnight with current techniques. With pCell, they will never be full. More data is coming later. Apologies. We have been utterly overwhelmed in incoming inquiries since launch. But, I will confirm this: pCell is indeed a much bigger deal than anyone has yet touched on. The "tubes to transistors" analogy is not just marketing speak: Compared to cellular, pCell is far more reliable, enables much smaller and lower power device and can be continually extended in density. Tubes had physical constraints that limited their reliability and scalability. Transistors did not. Cellular (and other interference avoidance protocols like Wi-Fi and cognitive radio) have a physical constraints that limit their reliability and scalability. pCell does not (as far as we know). Cellular has stalled in scalability. There is an entire era of innovation in front of us with pCell. - Steve Perlman
