Qualcomm’s new QTM052 mmWave antenna module wins the 5G race

Article is BS. There’s a 1X4 array in that Qualcomm chip, but what the article doesn’t tell you is you’ll need multiple placed around your phone. I’ll guarantee that Intel demo is using much larger arrays in the fold out panels, which are needed to get appreciable gain.

The MIMO diversity is only usefull with strong signals in multipath. To collect weak signal, you still need physical aperture.

This is more impressive from a circuitry integration standpoint.

The article discusses at length the requirements for multiple antenna modules, the physics constraints driving this and the ability of the X50 to handle those.

> Qualcomm says they will have 5G phones on the market in early 2019.

Wow. Is the first 4G LTE phone coming in 2011 to the first 5G phone coming in 2019 what they envisioned as "long-term" evolution? I would've thought long-term would've meant like 15+ years.

It's all related to marketing. Someone got smart and learned that consumers don't like iterations of major wireless stuff.

My understanding is "5G" is really what "4G LTE" was originally planned as.

Dang, well I guess they got me with LTE, it does sound awesome. Not sure if I'll fall for it again though... 3G was actually slow, but with 4G I feel like network speeds are too fast for the servers to handle these days.

My conspiracy theory brain says this is mostly to do with network planning - Telcos make a lot more money from wireless.

>My understanding is "5G" is really what "4G LTE" was originally planned as.

It is not. 5G, NR mmWave are entirely new and has nothing to do with the original 4G vision, which was the 1Gbps Speed. Those are already supported with the latest LTE standard 3GPP Rel 14. Qualcomm and Intel both have modem support 2Gbps / 1.6 Gbps Speed.

I just hope the first generation 5G devices are more power efficient than the first gen LTE devices. That four hour battery life on my HTC Thunderbolt was unbearable.

Intel's 10nm is working, for just not for full blown cpu's yet.

This is a fascinating blog, a whole bunch of insider cpu stuff, with the guys personal vendetta on top of it all.

I wish I had the inclination to read it all.

Why does he have an axe to grind with Intel?

How is it 'winning' if there was no competition? There is Qualcomm, and a bunch of startups.

Intel isn't a start up my dude.
