Re: Science experiment? or real world?
I can ask both Google & the FCC, although Google hasn't been very talkative in the past.

Re: Science experiment? or real world?
I would guess the FCC is going to regulate the output and would think it wouldn't make differening requriement for terrestial vs. space radio waves. The advantage of putting the transmitter above the earth would be a direct line of sight to the receiver assuming a highly focused antenna on the transmitter side even at low power.

I am thinking that the signal output regulation from stratosphere maybe different from that of terrestrial environments. In other word, the google drone flying 12 miles above ground maybe allowed to output its signal at a much higher strength than terrestrial basestations are allowed.

Re: Science experiment? or real world?
Reading the Guardian article, it doesn't say that Google has cracked the range problem with 28GHz, just that it is experimenting with phased antenna arrays.

Re: Science experiment? or real world?
As for Google's 28 Ghz 5G system, I too am interested in finding out how Google overcame the range problem; even with the clear line-of-sight, the distance from the drone to the under handheld terminal is at least 12 miles, and even Samsung with its military radar derived array antena managed to reach only 1.4 miles, and this is considered to be light-years better than competitor's mmwave efforts.

Re: 5G - 28GHz - fiber or wireless

"28GHz was removed from being a candidate 5G band at WRC-15"

Yes, but its adjacent band 24.5~27.5 Ghz was selected instead, meaning the equipment developed for 28 Ghz will be able to operate in that band. So no big deal from the equipment sourcing point of view.

"60GHz as well as 5GHz expansion being 2 frequencies where new developments are making an impact."

Both are license-free bands with a maximum output of 1 watt, meaning any cellular system deployed in such license-free bands would be limited in range reaching a few hundred meters and you would not get a continous coverage, unlike Samsung's 28 Ghz 5G system with a 2 km service radius per basestation.

The thing about Samsung's 5G system that makes it superior to all other competing rival mmwave systems is its exceptional range of 2 km, which none of Samsung's rivals have been able to replicate to date. The 60~70 Ghz system demonstrated by Nokia has a range of 90 meters and is strictly a stationary system, for example.

So 5 Ghz and 60 Ghz license-free bands are pretty much useless by themselves, they need some other system serving as a primary system, be it LTE or Samsung 5G, with the sole exceptions of Chinese and Japanese who both intend to develop and deploy China and Japan only 5G systems in LTE bands due to an abundance of spectrum available below 6 Ghz there, they have literally 200 ~ 500 Mhz of bandwidth available to give to each celluar networks.

5G - 28GHz - fiber or wireless
Just some notes:-

 

28GHz was removed from being a candidate 5G band at WRC-15 - though US/South Korea may look to use it, regulators see satellite's Ka-band as being as important if not more so.


For 5G fibre and wireless are importnat, it will be impossible to backhaul 10's Gbps without significant imporvement in fibre capacity. Witness the spend now to increase capacity for 4G.


Wireless in the home or office is an open market and one where google could play very well, 60GHz as well as 5GHz expansion being 2 frequencies where new developments are making an impact. There is a race on to bring 60GHz to SoC level including the antenna array, transceiver, baseband, power, etc.

Re: Science experiment? or real world?
This reminds me of Google's expansion into fiber services in a lot of parts of the U.S. I wonder how much of this 5G experimentation has to do with competing with companies like Facebook, which is offering free internet in some places. Does Google benefit from possibly deploying cheap 5G wireless?

Re: Science experiment? or real world?
In macro terms, mobile looks like it would have more attraction for these reasons: mobile data is coming to dominate the bit-moving business; building out mobile access is much less capital-intensive than overbuilding with a fiber access network; 5G truly is a greenfield play, despite the current misperception that it's basically just 4G plus 1.

Re: Science experiment? or real world?
If they are serious about it then Google fiber would be part of the 5G story... it makes sense to pursue an integrated high-speed access strategy using multiple techs.

It depends on the end goal. Google fiber has its raison d'etre as a catalyust for others -- the wireless developments shold in some way fit in with some sort of IoT play rather than wireless broadband I would think.

Hard to know where they're taking it... and early Friday evening, not much is mkaing sense to me right now...
