Thanx for your comment. Seems to make sense.

Several nanoseconds probably refers to the time resolution of the tracking method. 3.33ns would be about 1m, and later it's indicated that location resolution is to within a meter, so while the sentence is a bit nebulous, this seems to be the intent.

Process location in several nanoseconds

Well that seems too efficient to be possible. Maybe by several they mean 1,000...

Anyone know what the processing time is in engineering numbers (not marketing numbers)?

Backward compatible positioning indoors ... and privacy

I infer from the article that the positioning will all be done by the router so the consumer will not need any new hardware on their Smartphone to reap the benefits of the precise indoor positioning. I guess then the questions will be how quickly the map programs can implement the associated indoor maps ... and what options consumers have to "opt out" of being tracked.

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.
