This had a measurable impact on maritime safety. Nikolai Tesla , was a Serbian-American engineer and inventor. He chose to try these experiments himself and expand on them. Later, he invested the Tesla coil. These were used commercially until the s in sparkgap radio transmitters. The Italian inventor and engineer Guglielmo Marconi often receives credit for inventing radio.
He would later change the name of his company to the Marconi Company. By , access to two-way telegraphy that could cross the Atlantic Ocean was available commercially. The use of two-way radios in aviation began in Soon thereafter, both military and commercial ships were transmitting and receiving information through the radio waves.
This allowed them to communicate even when far out of sight of land. In the true power of wireless communication became known internationally. In , the first regulations around radio came into being. All in a lightweight, high performance, durable package without any moving parts, and extreme simplicity of operation, as the military demanded.
Other Walkie-Talkies Other walkie-talkies were used during the course of the war by other nations. The British, Germans, and Americans had their own portable radio designs. Since these various radios used different circuit designs, they were often invented independently of one another, and each can make some kind of claim to being the "first of its kind". There was a large variance in the performance and portability of these various designs, however.
And starting in , it teamed with Motorola on a digital variation of SMR that could hold more bandwidth. The technology, originally called Motorola Integrated Radio System, would allow six times the number of users on a single part of the bandwidth compared to the analog version of SMR. In other words, Motorola and Fleet Call had figured out a way to replace an analog radio protocol with a mobile phone protocol, and Fleet Call was well-positioned to take advantage of the market shift.
The company was buying out competitors left and right for pennies on the dollar compared to the acquisitions that comparable cellular companies had to make to build out their networks, and this made the company a stock market darling in the early 90s. Bauer told The New York Times in Basically, the only thing that needed to change was the company's name. In , Fleet Call planned to launch a mobile phone service that August in Los Angeles under the name Nextel, and soon changed its name to reflect the shift.
Also around this time, the FCC changed its rules, allowing companies to be licensed nationally to use the spectrum , rather than regionally. By leveraging a mobile technology that had been seen as less attractive compared to cellular phones and reinventing it, Nextel had earned a huge leg-up when it entered the market and launched its iDEN mobile network—and it did so, of course, with a killer feature no other mobile phone had.
The only downside, and one that took a little while to solve, was the fact that phones with the walkie-talkie-style push-to-talk technology cost a little more at first. As YouTuber and former Nextel employee Michael "MrMobile" Fisher noted earlier this year , Nextel fostered an interesting reputation among mobile companies, using its ties to the original fleet technology to sell itself as a business-oriented company that didn't care so much about games on phones.
But there were problems with this setup that appeared over time—particularly with emergency systems that greatly relied on the same MHz frequency that Nextel's cellular functionality did.
A Firehouse piece noted that more than 1, reports of interference with police, fire, and ambulance systems had been reported due to the Nextel system's close proximity to the public services.
Unfortunately, there is no where to move public safety radio frequencies as the spectrum available to public safety has been exhausted. This caused a lot of problems for Sprint Nextel, which had to figure out a way to move its spectrum to a completely different part of the MHz spectrum, closer to the MHz section, another portion of the spectrum allocated to iDEN.
It cost the company billions, but they eventually pulled it off. Push-to-talk phones still exist, but they've become extremely niche. It's worth pondering whether walkie-talkie phones would still be popular had the Sprint-Nextel merger never happened. Recently, Mark Cuban turned some heads when it was announced that he was trying to buy the Broadcast.
Because of the war there was a shortage of product names. Many name writers were off fighting the Axis. And new weapons and other war paraphernalia were being invented at an unprecedented rate and they all needed names. The only name available fitting this particular device was walkie-talkie, which had been gathering dust in the naming archives for years.
Sounds like a venereal disease.
