Chapter 91: The Mother of CDMA

Many years later, John vividly remembers what happened in the office of Cornelius Jr. on that sunny afternoon in June 1941. Pen "Fun" Pavilion www.biquge.info

At that time, in order to find out whether the rumors about "Adele is Alva's second" were behind it, he drove to the Washington branch of ABC Company to meet with Cornelius Jr.

Because he had already called beforehand, John was directly ushered into the office of Cornelius Jr. as soon as he arrived, by the secretary who had been waiting at the door of the company.

As a result, Cornelius Jr. was not in the office. Waiting for him was an uninvited guest.

"Reilly! Why are you here? What about Cornelius? John asked, somewhat surprised.

Since the flagship product of Draco Defense Technologies, the M1 anti-tank rocket launcher, was hit in British and American military circles, Reilly, a former arms dealer who did not enter the industry, has become a hot upstart in the arms industry, and his schedule is simply busier than John's.

Since the beginning of the year, he has handed over the daily work of the security department of FedEx and the "White Mountain Brigade" to a deputy named Edward Johnson, and devoted himself to the development and production of Type 63 107mm rocket launchers.

At the end of this month, the new weapon will be unveiled at Draco Defense Technologies' second product launch, when Reilly is not staying at the R&D center in Massachusetts, but is doing it here at Cornelius Jr., Washington. Anti-tank rocket launchers and rocket launchers are not civilian weapons, so there is no need to advertise them on ABC TV.

"What a coincidence, John. Cornelius will be here in a moment. Reilly smiled and said, "I'm running errands for you, you're the boss, I'm not going to do my best." ”

"Running errands for me?" John was even more confused, what does this have to do with him.

"You don't remember? Didn't you ask Dvořák to bring a beautiful woman to me last week and ask us to add a new radio aspect to the pitch meeting? We at Draco are not strong in this area, so I came to Cornelius for help and asked a few experts to help with the technical validation of the new product. ”

As soon as John heard it, he knew that it must be Dvořák's kid who was playing the trick of "false decree" behind his back. He meant to ask Draco to send someone to contact the female inventor and help Dvořák round it up. Who asked them to put that new invention on the company's recommendation meeting?

But then again, Reilly isn't an opinionated person either. If the new invention was not reliable, he would have called him to complain a long time ago. Now that he has agreed to Dvořák's request, it means that there is something wrong with this invention patent.

John immediately became interested in the beautiful inventor's radio patent: "What kind of invention patent is that?" Is there a market prospect? ”

"You don't even know what an invention is?" Reilly was surprised, "Dvořák told me that you are very optimistic about this technology. ”

"This dead fat man, running trains with his mouth, even lied to me." Seeing John's stunned expression, Reilly also realized that he had been fooled. "I thought you had a crush on Miss Heidi, well, Miss Heidi's invention that made Dvořák bring her to me."

John didn't even notice the strange tone and expression on Reilly's face when he said this. He was already stunned by the name mentioned by the other party. Miss Heidi, female inventor, radio technology patent. Dvořák's beautiful inventor friend can't be Heidi Lamarr, known as the mother of CDMA.

"Isn't that Miss Heidi you're talking about the same Heidi Lamarr from MGM?" John hurriedly asked.

That's right, it's her, the one who played "Enchanted" (Hedy Lamarr appeared naked in that movie, becoming the world's first actress to dedicate her life to art). Together with a pioneering composer named Georges Antell, she invented a radio "frequency hopping device". To be honest, if Dvořák hadn't told me that you were optimistic about the technology, I wouldn't have believed that a woman who acted in a movie and a composer who played jazz could come up with any radio patents. ”

John was excited. Radio "frequency hopping technology", also known as "spread spectrum communication technology" in later generations, allows many people to share radio signals in the same frequency band. In the future, this invention will be widely used in military computer chips, mobile phones, wireless phones and Internet protocol research and development, satellite positioning systems (such as GPS), space shuttle ground communication, and WiFi. Qualcomm has grown from a small company to a Fortune 500 company by relying on the CDMA wireless digital communication system developed on the basis of this technology.

Even now, this technology is quite "lucrative" in the military field and can be widely used in aircraft and torpedo navigation systems. Especially at present, the fish commonly equipped by various countries are guided by wireless signals, and the other side can use radio signals of the same frequency to interfere with torpedoes to achieve the purpose of evasion. Heidi's invention can extend a single wireless signal frequency to multiple frequencies, solving the technical bottleneck of a single wireless signal channel.

Dvořák, this kid is really a lieutenant, and Pickle Girl can help him dig a big gold mine. Historically, this great invention can be said to have been completely buried because of Heidi Lamarr's special status. Although the invention was finally certified by the U.S. Patent Office in 1942, most people still considered the invention based on the principle of a mechanical player piano to be unreliable.

Even if Heidi finally donated the invention to the U.S. government for free, the military didn't take it too seriously. For one thing, they thought it was impossible for an actress and a musician to know more about radio than a military weapons expert. Second, Heidi's ex-husband, Austrian arms tycoon Mandel, had close contacts with the Nazi high-level, and Heidi had a record of contact with Hitler and Mussolini. The military wondered if Heidi was fooling them with it. Rather than using this technology, they are more interested in using Heidi's pretty face to help them sell war bonds.

Now, if the patent were in John's hands, it would be a different story. John had every confidence that he would shine in the ensuing war. First of all, Hughes Aircraft Company's aircraft navigation system can be used. Secondly, with his relationship with Secretary of the Navy Knox, it is not difficult to get the Navy to pay for it.

The more John thought about it, the more excited he became: "Reilly, how far has this radio frequency hopping device been developed, and when will there be a mature product?" ”

"We have piloted a batch of samples and are doing small-scale testing. Didn't I come to Cornelius to borrow a few radio experts to participate in the revision of the patent application? Miss Heidi and Mr. Antelle are not professionals after all, and their patent application materials need to be significantly revised, otherwise it will be difficult to pass the examination of the patent office. ”

"John, you're here." As he spoke, Cornelius Jr. walked in with a couple of middle-aged men. He greeted John first, and then said to Reilly, "Reilly, these are all radio experts from ABC Corporation. They're interested in what frequency hopping device you're talking about. I don't know, when will Miss Heidi arrive? ”

"Will Miss Heidi be coming too?" Without waiting for Reilly to answer, John preemptively asked. He was very curious about the most beautiful female scientist who would be inducted into the American Inventors Hall of Fame in the future. In his previous life, he had seen some photos of Hedy Lamarr on the forum, but those were stills. Although each one is unpretty, the differences between the photos are very large. He really wanted to know what Hedy Lamarr, known as "the most beautiful woman in the world", looked like.

"It should be soon, I made an appointment with her at 3 p.m." As he spoke, both Reilly and Cornelius Jr. looked down at their watches at the same time. John didn't pay attention to the question of why they looked down at their watches, even though there was a clock hanging on the wall of his office. I didn't notice that when Hedy Lamarr was mentioned in front of him, there was a strange look on the faces of Reilly and Cornelius Jr.
