I suppose NGH will be used for commercial purpose, collaborating with cellular technology to improve coverage. There will still be individual WiFi AP/ Router being used by various parties. For example, an independent coffee shop deployed Hotspot for their customers. I hope the flooding of NGH will not affect the service quality offered by the independent coffee shop.

This is nice as long as the carriers don't flood the ISM bands with closed Wifi networks. I would be willing to bet that this is going to become an issue in urban environments fairly soon. Free Wifi is a serious competitor to them in the growing data communications market segment. Larry M.

It will be very interesting watching the transition to NGH. I applaud these efforts and hope they are very successful. The current Wi-Fi experience is good but definitely needs improvement, especially in the areas of accessibility/login and security.

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.
