NIH: Hard water is good for you

Pallav Sengupta, 2013 Aug; 4

In the past five decades or so evidence has been accumulating about an environmental factor, which appears to be influencing mortality, in particular, cardiovascular mortality, and this is the hardness of the drinking water. ...

Hard water has no known adverse health effect, WHO says at its Geneva Conference. In addition, hard water, particularly very hard water, could provide an important supplementary contribution to total calcium and magnesium intake. ...

In most large-scale studies, an inverse relationship between the hardness of drinking-water and cardiovascular disease has been reported. ...

Important findings in this field were provided recently by Taiwanese scientists. In most of their studies, the authors indicated a negative statistical association of various types of cancer morbidity/mortality with the hardness of water and calcium. ...

For years, I've been (jokingly) telling people that I drink tap water because "calcium and iron are good for you". Apparently, there are studies that back this up.

Read the full article for all the details. The upshot of it is that although additional study is needed, it seems that hard water is either beneficial to health or has no impact, depending the health aspect in question.

Light Reading: AT&T, Ericsson & Qualcomm Get Ready to Test 5G Radio in 2017

AT&T, Ericsson & Qualcomm Get Ready to Test 5G Radio in 2017
Dan Jones, Mobile Editor. 1/4/2017

AT&T, Ericsson, and Qualcomm say that they are getting ready to test the initial 3GPP 5G New Radio (NR) specification in the second half of 2017.

The trio are preparing to test high-band frequencies for next-generation 5G technology, which should deliver "multi-gigabit Internet service" over the air. For the average Jane or Joe Blow on the street, this would mean an HD film downloaded wirelessly to their phone. Mobile 5G services are expected to arrive around 2020. AT&T Inc. (NYSE: T) and Verizon Communications Inc. (NYSE: VZ), however, are trying to push out fixed 5G wireless before that, with friendly trials expected this year. (See 5G in US: Will Spectrum Be the Speed Bump?)

Although 5G consumer services are still several years away, I'm glad to read that the big players in the business are far enough along that they will be conducting trials later this year.
