If they would improve the battery life of thus damn smart phones ,

Interesting question. Very few, if any, could have foreseen where we would be today, let's say 50 years ago in 1964. But I think we might be better equipped to approach the question going forward.

How much data do we need local access to? For instance, would it even be desirable to have all financial transactions in the world, on a real time basis, go through our personal mobile device? It would need to be a very powerful mobile device to make use of such enormous quantities of data. I'm sure we could find more efficient ways to get the desired results.

The real question is how much unique information could be available to a mobile device that would be useful to transmit? These could include biomentric information, precise location and orientation information and various user inputs like voice, camera, keyboard etc. And what information needs to be received to present, control, or otherwise be useful.

Another is that each mobile device, or other categories, could be a peer to peer part of some sort of mesh type network. But even here, maybe especially, each node would carry a small part of aggrigate traffic.

I believe the future will bring better understanding of how much data personal mobile devices need and there will be a useful limit, not defined by RF capability but by utility.

Its just like everything else.  We will always push for more.  If the cost structure will support it, then 5G will succeed and I doubt it will be the last.

Aside from the definition of what 5G is, do you honestly believe there will ever be a point where everyone just sits back and says "you know what? We've got enough."?

Re: 28GHz or 39GHz - Is this mm wave?
Les_Slater   1/10/2014 10:31:00 PM
If I'm doing my math right then 39GHz is 7.7mm and 28GHz is 10.7mm. Sounds millimeterish to me.

I wonder can we call 28GHz and 38GHz mmwave?

Beam forming phased array antennas

28 or 39 GHz will not work in all scenerios but will in many. Beam forming will be key at both the mobile end and at the base station. Also terrain mapping for reflective surfaces in urban environments as well as attenuation factors through walls.

The mobile device will need higher accuracy location mechanisms and orientation info to report to base stations so beam forming will be colabrative effort.

Seemless handoff of course, not only geography, including obstructions but bands too.

Given that even 2.4GHz wifi works with a range of about 5 metres max in my house due to the nature of the walls,  I don't think 60 GHz will really cut it.

I could not get a cellular signal from a 1800Mhz provider in my house , despite being less than a mile away from the base station. Only a 900Mhz signal would go through the trees in the way...

Rick, how is 5G defined? 4G is 1 Gb/s throughput for stationary links I think, what is the corresponding number for 5G? and why do we need 5G? isn't 1 Gb/s enough? do we need to watch HD movies on msart phones? Kris

39 GHz in your smartphone

OK, wireless engineers, I'd like to hear what kind of challenges we will need to tackle to get to a 2020 smartphone that roams from 2 and 39 GHz for cellular service.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
