In a twist of irony, US immigration policies have left China with the upper hand in 5G technology. Who knew denying a Caltech and MIT graduate a visa renewal could be such a game-changer?
Roaming charges are history! Experience the freedom to travel and stay connected.
Remember when you couldn't activate your mobile #data when you were abroad to avoid high charges? With Roam Like at Home you can enjoy the same benefits wherever you go:
📱 Lightning-fast #5G for seamless connectivity
💰 No unexpected charges, peace of mind
🆘 Improved access to emergency services for safety
The end of #roaming charges has revolutionised #travel and communication, bringing #Europe closer together.
In 2009, a Turkish graduate of the California Institute of Technology and the Massachusetts Institute of Technology, #Erdal#Arikan, published a paper that solved a fundamental problem in information theory, allowing for much faster and more accurate data transfers.
Unable to get an academic appointment or funding to work on this seemingly esoteric problem in the United States, he returned to his home country.
As a foreign citizen, he would have had to find a U.S. employer interested in his project to be able to stay.
Back in Turkey, Arikan turned to #China.
It turned out that Arikan’s insight was the breakthrough needed to leap from 4G telecommunications networks to much faster #5G mobile internet services.
Four years later, China’s national telecommunications champion, #Huawei, was using Arikan’s discovery to invent some of the first 5G technologies.
Today, Huawei holds over two-thirds of the #patents related to Arikan’s solution
—10 times more than its nearest competitor.
And while Huawei has produced one-third of the 5G infrastructure now operating around the world, 💥the United States does not have a single major company competing in this race. 💥
Had the United States been able to retain Arikan
—simply by allowing him to stay in the country instead of making his visa contingent on immediately finding a sponsor for his work
—this history might well have been different.
"Riesige Freude" in Sittenbach (Landkreis Dachau): Mobilfunkgegner verhindern Telekom-Sendemast.
Die Initiative einer Seniorin, die "Kinder" vor angeblichen Gesundheitsgefahren schützen will, wird von der Verschwörungsideologen-Gruppe "Diagnose Funk" beraten. Sittenbach bleibt jetzt ein Funkloch.

#Internet#Starlink#5G#SolarPanels#OffGrid#Technology
I was hoping for advice /help please ,I am not at all clear about 5g and other off grid internet options.I had 4g my last place it seemed to use very little power ,but had to be ended when the forestry blocked the signal.Here we have highland wifi ,but my daughters getting starlink which I refuse to use ,EVER .I will carry on paying for highland wifi ,but need something portable for use in a tent/caravan at the off grid site below soon
Transferred two numbers yesterday, from Cricket. The process was much easier and quicker then I thought. So that was great. Hoping to transfer the other two lines this evening, from Mint.
Did a speed test at a rural park near me and got speeds of 393.8Mbps⬇️ & 41.5Mbps⬆️
Soooo, auch wenn es mir etwas widerstrebt 1&1 (hat gerade mal eine Hand voll Antennen in München) mit Telekom, Vodafone und Telefonica zu vergleichen, so muss ich es doch tun, wenn ich hier keinen Blödsinn verbreiten möchte.
Also alle vier deutschen Mobilfunknetze unterstützen #ipv6 . https://www.thomas--schaefer.de/apn-ipv4-ipv6.html #5G
Having power issues sometimes is the "It's always DNS" equivalent in the embedded electronics world.
When we wanted to put one of our customer projects into operation, we noticed strange problems with a Quectel modem that we had not had before. Of course, from a software developer's point of view, the software was initially suspected of causing problems. But slowly a different picture emerged ...
Read the full story and learn how important it is to always consider hardware when you're having software problems (and vice versa!):
Thanks to borrowing an eSIM from @zonuexe, I've now tested all four physical Japanese mobile networks, including the elusive Rakuten Mobile. My phone didn't lock onto their #5G, but seeing #LTE on them was good enough.
That's in addition to LTE and 5G on SoftBank and NTT, plus LTE on KDDI, that I was able to source myself :)
Yep, I'm that much of a cell network nerd. Any questions?
« Rien ne nous aliène à nous-mêmes et ne nous aliène le monde plus désastreusement que de passer notre vie, désormais presque constamment, en compagnie de ces être faussement intimes, de ces esclaves fantômes que nous faisons entrer dans notre salon d’une main engourdie par le sommeil – car l’alternance du sommeil et de la veille a cédé la place à l’alternance du sommeil et de la radio – pour écouter les émissions au cours desquelles, premiers fragments du monde que nous rencontrons, ils nous parlent, nous regardent, nous chantent des chansons, nous encouragent, nous consolent et, ne nous détendant ou nous stimulant, nous donnent le la d’une journée qui ne sera pas la nôtre. Rien ne rend l’auto-aliénation plus définitive que de continuer la journée sous l’égide de ces apparents amis : car ensuite, même si l’occasion se présente d’entrer en relation avec des personnes véritables, nous préférons rester en compagnie de nos portable chums, nos copains portatifs, puisque nous ne les ressentons plus comme des ersatz d’hommes mais comme de véritables amis ».
Spent the last week “swatting” 5G interference in several markets. All were solved with a #5G filter and dish tweaks except one, where we are a couple of blocks away from two different cell sites and it was really bad on the Westwood One transponder 17. Credit John Joslin at DAWN Satellite with a hack he heard from another customer. Use foil tape to seal the flanges. We tried it, and it worked. Gained a full point in EbNo and zero errors since applying it. Remember when you were a kid and you put aluminum foil on the end of your TV rabbit ears? This might be from the same category, but it actually worked for us. (And yes, there were a few bolts missing when the pics were taken.)
Random question, but do any of you #game on mobile data?
If so, I'm intrigued on what technology you use for it (e.g. #3G UMTS, 3G HSPA+, #4G LTE, #5G NR), what games you play on it (e.g. Splatoon 3, Mario Kart 8 Deluxe), what your current carrier is (e.g. EE, vodafone UK), what your area is (e.g. West Midlands, England) and how your experience is like for it (e.g. good, bad).
I don't know whether I'll ever get back to making videos, but if I do, one of the ideas I had was making a video about gaming on 4G.
Two footmen dressed in white approach the vehicle as it arrives. One opens the rear door. #Guo#Ping, one of #Huawei's rotating chairmen, steps forward and extends a hand as the guest emerges.
After walking a red carpet, the two men enter the magnificent marble-floored building, ascend a stairway, and pass through French doors to a palatial ballroom.
Several hundred people arise from their chairs and clap wildly.
The guest is welcomed by Huawei's founder, #Ren#Zhengfei, whose sky-blue blazer and white khakis signify that he has attained the power to wear whatever the hell he wants.
After some serious speechifying by a procession of dark-suited executives, Ren
—who is China's Bill Gates, Lee Iacocca, and Warren Buffett rolled into one
—comes to the podium.
Three young women dressed in white uniforms enter the room, swinging their arms military style as they march to the stage, then about-face in unison as one holds out a framed #gold#medal the size of a salad plate.
Embedded with a red Baccarat crystal, it depicts the Goddess of Victory and was manufactured by the Monnaie de Paris. Ren is almost glowing as he presents the medal to the visitor.
This #honored#guest is not a world leader, a billionaire magnate, nor a war hero. He is a relatively unknown Turkish academic named #Erdal#Arıkan.
Throughout the ceremony he has been sitting stiffly, frozen in his ill-fitting suit, as if he were an ordinary theatergoer suddenly thrust into the leading role on a Broadway stage.
Arıkan isn't exactly ordinary.
Ten years earlier, he'd made a major discovery in the field of information theory.
Huawei then plucked his theoretical breakthrough from academic obscurity and, with large investments and top engineering talent, fashioned it into something of value in the realm of commerce.
The company then muscled and negotiated to get that innovation into something so big it could not be denied:
the basic #5G#technology now being rolled out all over the world.
Huawei's rise over the past 30 years has been heralded in China as a triumph of smarts, sweat, and grit. Perhaps no company is more beloved at home
—and more vilified by the United States.
That's at least in part because Huawei's ascent also bears the fingerprints of China's nationalistic industrial policy and an alleged penchant for intellectual property theft;
the US Department of Justice has charged the company with a sweeping conspiracy of misappropriation, infringement, obstruction, and lies.
As of press time, Ren Zhengfei's #daughter was under house arrest in Vancouver, fighting extradition to the US for allegedly violating a ban against trading with Iran.
The US government has banned Huawei's 5G products and has been lobbying other countries to do the same. Huawei denies the charges; Ren calls them political.
Huawei is settling the score in its own way. One of the world's great technology powers, it nonetheless suffers from an inferiority complex.
Despite spending billions on research and science, it can't get the respect and recognition of its Western peers. Much like China itself.
So when Ren handed the solid-gold medal
—crafted by the French mint!
—to Erdal Arıkan, he was sticking his thumb in their eye.
With #LTE and #5g mobile connections, the demands on the voltage sources have also increased: In particular high peak currents of approx. 4 A @ 3.7 V and more can push some circuits and the voltage converters installed in them to their limits.
In the event of stability problems with mobile radio modems, it is therefore particularly worth taking a brief look away from the software and towards the hardware. Can the power supply really meet the high requirements? An examination with an oscilloscope shows even the smallest fluctuations in the millisecond range and can reveal possible problems.
In our specific case, we are investigating stability problems with a new modem, which can only be reproduced unreliably. In the video you can see that even small pings have a visible effect (voltage fluctuations of approx. 800 mV) on the voltage source.
Okay, I didn’t expect #5G to actually make a difference sub-6GHz. But here we are, with the fastest Speedtest I ever had on a cellphone.
Btw, this was inside a mall and I don’t even know where the tower is. #networking#internet

I wonder when #5G will become the standard and you don’t have to pay extra anymore to use it with some providers.. Do we have to wait for #6G for that? 😄
