"Tested ranges of Nokia and Ericsson's 15 Ghz systems are around 100 m"

Japanese publications have rather detailed description of NTT Docomo's testing with Nokia and Ericsson's 15 Ghz devices. This is how I know the range was around 100 m. Past 100 m, the transmission speed fell off the cliff with both systems.

"Samsung (28GHz) ... ranges up to 2 km."

This is from Samsung's official press release.

https://news.samsung.com/global/samsung-announces-worlds-first-5g-mmwave-mobile-technology

However, Samsung's new adaptive array transceiver technology has proved itself as a successful solution. It transmits data in the millimeter-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to 2 kilometers.

And yes, NTT Docomo also confirmed that they measured upto 4 Gbits/s on Samsung's 28 Ghz 5G system while driving around in a car at 40 mph. And Samsung 5G's receptive antenna was the only one they tested that was smartphone sized, vs suitcase sized antennas provided by Ericsson and Nokia.

So there is a world of difference bewteen Ericsson/Nokia and Samsung in terms on mobile reception, walking speed @ 100 m vs 68 mph @ 2 km, such that comparing them would be irrelevant.

Re: Small cells?
So basically Verizon deploys a fixed 5G data overlay in a few cities in the US? Geeeeee, that sounds exciting! And does nothing to fix 4G overcrowding anway. You're dreaming if you're thinking Verizon is going to use a single RAN vendor for a nationwide mobile deployment.

"so where does that leave us?"

Those running out of bandwidth today will have to buy from the single vendor.

Those who have extra room in bandwidth may choose to defer.

Re: Small cells?
Good for them! Operators aren't going to do a major rollout with a single RAN vendor, so where does that leave us?

Tested ranges of Nokia and Ericsson's 15 Ghz systems are around 100 m; 28 Ghz would be less than that.

Nokia and Ericsson are positioning its mmwave 5G systems as small-cells in high density urban area, whereas Samsung is positioning its mmwave 5G sytsem as a direct replacement of traditional macrocell LTE systems with ranges up to 2 km.

Small cells?
I wonder if AT&T is testing indoor small cells given the range described in the word doc they sent to the FCC.
