Influence of signal frequency on the energy of radio links in free space

Influence of signal frequency on the energy of radio links in free spaceWhat changes when the applied frequency band is changed in radio communication is not always correctly formulated even by experienced radio amateurs. On the one hand, the formula for transferring Friis is extremely simple, and there seems to be nothing to discuss. On the other hand, in this formula, in addition to explicitly mentioning the wavelength λ, it is implicitly hidden in other coefficients. There are many statements, notes and articles, that with higher frequencies the power of radio links is worse, there are no less articles of "myth exposures" - saying that there is nothing worse than ...

By the Day of Radio. O communication, you are a world

By the Day of Radio. O communication, you are a worldToday is the Day of Radio and Communication, perhaps the most beloved engineering festival in Russia. It is celebrated by employees of cellular and fixed communication, radio, developers, engineers. And this is not surprising, because no company, no one thinks himself today without communication. Every year at industry conferences and in radio and communication publications, a quick end or, at best, a transformation beyond recognition is predicted. But nevertheless, technologies are continuously developing: in 2003 there was still a paging communication, and this autumn the world is waiting for ...

Although the smooth evolution of the mobile Internet has spanned decades (and continues to this day), mobile data access has rapidly changed our lives already in the early and mid-2000s, when third generation networks were distributed.
 
While the phones became less and more productive, the Internet adapted to mobile platforms, the data transfer rate grew (4G networks improved the bandwidth by about ten times compared to 3G), mobile communication became ubiquitous.
 
 
Today we will tell the story of the legendary technological breakthrough in the telecom: the transition of technology ...

Technologies of the future: rejection of physical SIM-cards

Technologies of the future: rejection of physical SIM-cards
 
Shot from the movie "Kingsman: The Secret Service" (2015)
 
 
For years the device of physical SIM-cards almost did not change. Of course, they have decreased in size: Mini-SIM 25 x 15 mm, Micro-SIM 15 x 12 mm, Nano-SIM 1?3 x ?8 mm. However, SIM cards retained functionality and compatibility regardless of the format. And you still need to insert a small plastic card into your phone or tablet to connect to the mobile network.
 
 
When the market first appeared dvuhsimochnye smartphones, they aroused great interest among users who tried to solve the problems of network availability, savings, roaming ...
