Unfortunately, there is no where to move public safety radio frequencies as the spectrum available to public safety has been exhausted." "Often the two systems frequencies are too closely positioned within the 800 MHz radio spectrum. "The co-location of commercial wireless vendors and public safety radio systems within the 800 MHz radio spectrum is where the problem begins," the article noted. 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. ![]() 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 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. And starting in 1991, it teamed with Motorola on a digital variation of SMR that could hold more bandwidth. At the time of its 1987 formation, Fleet Call worked to acquire many of the niche players that had been built around this technology at the time, which were mostly working on analog systems.ĭuring the early years, the company spent time putting together the chess pieces and working with the FCC to allow it to expand the technology's reach. Now Fleet Call (which, again, is an awesomely cheesy name), took advantage of specialized mobile radio (SMR), a wireless technology that had been allocated by the Federal Communications Commission in the 1970s for the purposes of two-way radio systems. ![]() And this is reflected by Nextel's awesomely awkward original name, Fleet Call. ![]() The company's roots were not with mobile phones, as it turns out, but taxi and trucking fleets. The fun part about this is that the feature actually was what the entire company was built around in the late 80s and early 90s. (Gross also invented the pager and wireless phone, so even if he wasn't the outright inventor, he has other claims to success.) "Without taking anything away from Gross' accomplishment, Hings' CM&S field radios were already in production at that time," the Hings website states. (He didn't come up with the walkie-talkie term, instead calling it a "pack set.")Ī website dedicated to Donald Hings' memory suggests that there were examples of Hings' invention in use as early as 1937, predating a similar invention by Canadian-American inventor Al Gross, who built his own ham radio in the early 1930s, but expressed a desire to create a portable version- which he successfully built in 1938, soon handing his idea to the US military. Hings, an employee of a Canadian mining company who came up with the device as a way to help workers in remote areas communicate with one another. The person with the strongest case for inventing the walkie talkie, though, is perhaps Donald L. It was an idea that a lot of people had around the same time, and all added their own twist on the equation. More complicated is the question of who invented it-with credit being given to individual inventors, the Galvin Manufacturing Corporation (later known as Motorola), and the US Army, which popularized it among an audience of soldiers who used it to communicate in the field. And it had its original moment in the sun around World War II.
