Unknown Mobile Generations, What's 3.5G?

If you are an active mobile phone user you probably know that there is a really wide variety of methods major mobile carriers use to promote a new mobile communications standard and advertisers rarely study the technical side of that standard. That's why they always call a new standard of mobile communications a new generation. In the result we often face pretty unknown mobile generations, 3.5G for example. In a matter of fact even a 3G is a simple slogan that was created for promotion a technology that was simply faster than 2G. In the meantime, 2G has its own divisions, which were created by promoters as new standards were introduced in a second generation. They are 2.5G that emerged when the GPRS technology was presented and 2.75 or 2.9G for promoting EDGE standard. But nevertheless all those 2.5 and 2.9G were the second generation.


That's the reason why we at Jammer-Store Company decided to try to sort things out and understand what they've sold use under the 3.5G brand name. As you know, there is an International Telecommunications Commission and that organization develops and determines the standards for mobile communications. And that organization states that the EDGE technology, which is branded as 2.9G is closer to a third generation, or 3G and it would be right to brand it that way.


Also it is worth mentioning that modern mobile phones work with those networks in a different manner. If you'll connect an iPhone to a 3G network it will show a 3G icon on the status bar, while the device will work with HSPA standard and its varieties like HSUPA, HSPDA or HSPA+. That is so because the speed of the 3G may vary in a great spectrum, and various protocols work with different speeds. The original 3G network without additional superstructures would be able to reach a maximum data transmission speed up to 384 Kbit/s, which is a rather low speed for modern mobile networks.


But regardless the 3G is rather popular among not only smartphone users. That generation is frequently used in hidden video surveillance, because data transmission speeds allow to stream video in real time and low energy consumption will ensure that a hidden wireless camera will work longer. That's the main reason of the growing popularity of 3G signal blockers.


Android based smartphones display H with a 3G icon in a status bar, when connected to a 3G network. The reason is that Android devices can distinct a common 3G network form its more advanced superstructures. The H letter is diplayed in the status bar when the data transmission speed in the network is 2-15 Mbit/s. We should also mention that 3.5G is actually a brand name for all the superstructures of 3G.


Another interesting fact is that the LTE standard, that is associated with a fourth generation of mobile communications is actually still closer to 3G. LTE failed to meet the ITC's expectations and that's why it is still 3G, but much more advanced. They even use different frequencies, while 3G works with 2000-2100 MHz, LTE uses 875 MHz, though those frequencies may vary depending on the country and the carrier. That LTE standard is used not only for mobile Internet access, but for hidden video surveillance too. Such hidden cameras are still very expensive and rare, but they are the most reliable way for hidden video surveillance. That's why we've made our best to create an LTE jamming device that is compatible with all the previous mobile generation and standards.
