Apple Needs Some RF Design Engineers

Apple Needs Some RF Design Engineers

A Chinese man walks past a authorized Apple retailer in Beijing on July 12, 2010. Despite a new flagship showroom that just opened in Shanghai, Apple is striving to overcome price disadvantages and an underground market. Most fans of its Apple products here have been buying their iPhones, iPods and Mac computers from smugglers who operate through underground electronics markets.  UPI/Stephen Shaver Photo via Newscom

Yep, as I suspected….

It’s official. Consumer Reports’ engineers have just completed testing the iPhone 4, and have confirmed that there is a problem with its reception. When your finger or hand touches a spot on the phone’s lower left side—an easy thing, especially for lefties—the signal can significantly degrade enough to cause you to lose your connection altogether if you’re in an area with a weak signal. Due to this problem, we can’t recommend the iPhone 4.

That’s Consumer Reports, incidentally, which put the phone in an RF-isolated room to perform their tests along with a base-station emulator.

Oops – that’s about as close to proof as you’re going to find.  In an RF-quiet environment it’s pretty easy to prove your case, and it appears that CR did so.

The tests also indicate that AT&T’s network might not be the primary suspect in the iPhone 4′s much-reported signal woes.

"Might" not?  

I have never been impressed with the iPhone (any generation) in terms of RF.  Ever. It has always been a "form before function" device from my perspective, all the way back to the original units.  Then again I’m spoiled – the best RF-performing GSM phone I’ve ever used was a Nokia 3395.  I may still have one laying around here somewhere, and all of my old Nokias (including a 6610 which was nearly as good) still work just fine.  Old, yes, but one thing Nokia does know how to do is design and build an RF section.

Incidentally, buying devices that work before selecting them for "sex appeal" may be why I’ve never had a material problem with the "can you hear me?" BS that so many suffer with when it comes to cellphones.  I guess my view is that a cellphone is for communicating rather than trying to shag some hot chick at the local bar by flashing my "bling."

This is a common flaw for consumer devices – be sexy rather than be smart – or good.  Of course sex sells, and so the more "sexy" you can make something look the better it sells, and as long as you remain within the "acceptable" functionality envelope you don’t get hurt – too badly.  Witness Motorola, which had the "hot" phone for a long time…

French philosopher Voltaire famously quipped: “If God did not exist, it would be necessary to invent him.” Something similar can be said of modern monetary theory, also known as MMT, because it may be the economy’s only hope to get through the pandemic.

Doc Copper Bear Market Resistance Kiss In Play!

Courtesy of Chris Kimble

Is ole Doc Copper about to ends its 9-year bear market? I suspect we will find out the answer to the question very soon!

Doc Copper has created a series of higher lows inside the falling channel (1) since it peaked back in 2011.

The rally from the lows in March of this year, has Doc Copper testing the top of its falling channel as well as a support/resistance price zone at (2).

With Doc Copper still in a bear market (lower highs for 9-years), this price test comes into play as important resistance at (2).

If Doc Copper breaks out at (2), it would send...

Texas, Florida, Arizona, Georgia – The Branch COVIDIANS Are Still Burning Down the House

Courtesy of Lee Adler, WallStreetExaminer 

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
