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…

CDC Reaffirms Warning Against Nonessential Travel, Including Cruises

By Evan Gove of Porthole Cruise

The CDC has updated a level 3 warning to avoid nonessential travel, citing cruises in particular as a known spreader of COVID-19.

The update on the CDC website doesn’t leave any room for interpretation: 

Cruise passengers are at increased risk of person-to-person spread of infectious diseases, including COVID-19, and outbreaks of COVID-19 have been ...

The 2016 election was a referendum on free trade, which many blamed for destroying millions of American manufacturing jobs. In 2020, it could be about the merits of trade wars.

During President Donald Trump’s first term, he tore up deals, launched a trade war with China and renegotiated NAFTA. His campaign claims the war was a succes...

Doc Copper/Gold Indicator Breaking Out Again?

Courtesy of Chris Kimble

The Doc Copper/Gold ratio broke above a 2-year falling channel back in 2016 at (1). Following this breakout, it rallied for the next year. During that year, Copper related assets did very well!

The ratio peaked in the summer of 2018 and created a series of lower highs over the past two years.

The strength of late has the ratio attempting to break above dual resistance at (2).

If the ratio continues to push higher and succeeds in breaking out, Copper, Basic Materials (XLB), and ...

The Dow Gann Angle Target 3 (from 2007 top) is on the table, and what a ride that will be. The FED went BRRRRR is all the fundamental news you need to know. Gann angles are very good tool to see how the masses are pushing price.

The last two US elections saw Bitcoin and the DOW rally well for 6 months, due to stimulus. The most bearish 2020 US Election case for the markets is a Biden win with the Senate and Congress controlled by the Democrats, somehow this blog feels that is very unlikely. So what could go wrong!

COVID-19 Forces More Than Half of Asset Management Firms to Accelerate Adoption of Digital Marketing Technology

By Jacob Wolinsky. Originally published at ValueWalk.

There is no doubt that the use of technology to support client engagement initiatives brings both opportunities and threats but this has been brought into sharp focus this year with the COVID-19 pandemic.

The crisis has brought to the fore the need for firms to enable flexibility in client engagement – the expectation that providers will communicate to clients on their terms, at their speed and frequency and on their preferred channels, is now a given. This is even more critical when clients are experiencing unparalleled anxiety from both market conditions and their own personal circumstances.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

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...
