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.

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…

The economy is recovering faster than had been expected as recently as this spring. Great reason to panic, apparently.

WSJ:

Federal Reserve officials signaled they expect to raise interest rates by late 2023, sooner than they anticipated in March, as the economy recovers rapidly from the effects of the pandemic and inflation heats up.

Their median projection showed they anticipate lifting their benchmark r...

Questions For The Fed: When Do Inflation & Financial Risks Force A Change In Policy

Courtesy of ZeroHedge View original post here.

by Joseph Carson, former chief economist at Alliance Bernstein

If I could attend the June 15-16 Federal Open Market Committee, I would ask the voting members what are they trying to accomplish? Based on efforts to help the economy recover and boost general inflation, aggressive monetary accommodation has resulted in more general inflation than any reasonable person would have expected. Is it still appropriate to call the uptick in consumer price inflation "transitory?" Also, easy money has helped fuel the record surge in the marke...

Crypto: Congress Dawdles as $1.7 Trillion Con-Game Goes Unregulated, Threatening Reputation of U.S. Markets

Courtesy of Pam Martens

If you want to get your hair cut outside of your home in the United States, the job has to be done by a licensed worker at a regulated business. The same thing applies to plumbers, electricians, home inspectors, real estate and insurance agents. They all require a license and are subject to regulatory scrutiny.

Likewise, commodities like corn, sugar, wheat, lumber and oil are all traded on regulated exchanges which are overseen by a federal regulator.

But, for reasons that have yet to be explained to the American people, when it comes to the $1.7 trillion cryptocurrency market – which is effectively a con-g...

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

Managing Investments As A Charity Or Nonprofit

Maintaining financial viability is a constant challenge for charities and nonprofit organizations.

Q4 2020 hedge fund letters, conferences and more

The past year has underscored that challenge. The pandemic has not just affected investment returns – it’s also had serious implications for charitable activities and the ability to fundraise. For some organizations, it’s even raised doubts about whether they can continue to operate.

The Suez Canal: A Critical Waterway Comes to a Halt

On March 23, 2021, a massive ship named Ever Given became lodged in the Suez Canal, completely blocking traffic in both directions. According to the Suez Canal Authority, the 1,312 foot long (400 m) container ship ran aground during a sandstorm that caused low visibility, impacting the ship’s navigation. The vessel is owned by Taiwanese shipping firm, Evergreen Marine.

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...
