A much better way to get a strong Wi-Fi signal.

At press events gadgets that use WiFi often don't work well because so many people there are all using WiFi. That's why I was attracted to the new Portal device. As you'll see in the video we shot there that they were using their Portal WiFi device to stream four 4k videos and they all looked great - no buffering at all. The company says Portal is built for crowded and demanding urban environments. The said the primary cause of WiFi being slow and unreliable is overcrowding of the shared public radio airwaves that all WiFi devices compete to use. Portal is designed to be a WiFi system unlike any other. Their “Fast Lanes Technology” lets it use exclusive protected radio channels to eliminate the crowding and congestion that is increasingly common with WiFi. (They hard to work a long time with the FCC to achieve this.) Then the device also uses nine innovative and powerful internal antennas arranged in arrays support the latest radio techniques like MU-MIMO and beamforming for even longer distance. Portal combines the security and privacy capabilities of iOS or Android devices with those of WiFi. This results in your network being much more robust against anyone trying to hack it. Portal also protects your family’s privacy with things like continual intrusion detection, geo-fencing and ID obfuscation. The video on their Amazon page (link below) helps make it clear how they can offer a much better WiFi signal that other routers. And it's priced like many other high-end routers at $199.99. It starts ships November, 2016, but can be preordered.
