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…

Hong Kong Protests Go Global: China Demands Investigation After Lam's Justice Minister Wounded In London

Courtesy of ZeroHedge View original post here.

Chinese officials slammed American lawmakers who are advancing a bill designed to protest Hong Kong's quasi-independent status guaranteed by the legal handover agreement between the British and the Chinese, but the US isn't the only major western power that's creating problems with the increasing dangerous situation in Hong Kong.

Hong Kong's Justice Minister Teresa Cheng took a nasty tumble last night during a confrontation with pro-democracy sympathizers who came out to protest her presence in London. ...

Dow Jones cycle update and are we there yet?

Courtesy of Read the Ticker

Today the Dow and the SP500 are making new all time highs. However all long and strong bull markets end on a new all time high. Today no one knows how many new all time highs are to go, maybe 1 or 100+ more to go, who knows! So are we there yet?

readtheticker.com combine market tools from Richard Wyckoff, Jim Hurst and William Gann to understand and forecast price action. In concept terms (in order), demand and supply, market cycles, and time to price analysis. 

Cycle are excellent to understand the wider picture, after all markets do not move in a straight line and bear markets do follow bull markets.

Is Bitcoin a Macro Asset?

 

Is Bitcoin a Macro Asset?

Courtesy of 

As part of Coindesk’s popup podcast series centered around today’s Invest conference, I answered a few questions for Nolan Bauerly about Bitcoin from a wealth management perspective. I decided in December of 2017 that investing directly into crypto currencies was unnecessary and not a good use of a portfolio’s allocation slots. I remain in this posture today but I am openminded about how this may change in the future.

Silver Testing This Support For The First Time In 8-Years!

Courtesy of Chris Kimble

Its been a good while since Silver bulls could say that it is testing support. Well, this week that can be said! Will this support test hold? Silver Bulls sure hope so!

This chart looks at Silver Futures over the past 10-years. Silver has spent the majority of the past 8-years inside of the pink shaded falling channel, as it has created lower highs and lower lows.

Silver broke above the top of this falling channel around 90-days ago at (1). It quickly rallied over 15%, before creating a large bearish reversal pattern, around 5-weeks after the bre...

Lee's Free Thinking

Today's Fed POMO TOMO FOMC Alphabet Soup Unspin

Courtesy of Lee Adler

But make no mistake, if the Fed wants money rates to stay down by another quarter, it will need to imagineer even more money.

That’s on top of the $281 billion it has already imagineered into existence since addressing its “one-off” repo market emergency on September 17. This came via  “Temporary” Repo Man Operations money, and $70.6 billion in Permanent Open Market Operations (POMO) money.

By my calculations that averages out to $7.4 billion per business day. That works out to a monthly pace of $155 billion or so.

If they keep this up, it will be more than enough to absorb every penny of new Treasury supply. That supply had caused the system to run out of money in mid September.  This flood of paper had been inundati...

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
