Sanremo: flowers and 4.5G

If you are in Sanremo you can use our services on the 4.5G mobile network.

The 4.5G mobile network: as the name suggests, we are half way between 4G and 5G, namely a new generation network.
But what is the purpose of these developments? To surf the Internet more quickly, download a film in a few seconds, even if it is in 4K, in other words in “ultra” high definition.
The download speed, in Mbps (Megabits per second), is the parameter commonly used to measure the performance of a mobile network. It indicates the speed with which in 1 second, on a mobile phone, you can download a heavy file, like a video, for example.
4.5G reaches the maximum speed of 500 Mbps. A good step forward compared to the 42 Mbps possible with the 3G network in the first decade of 2000.  
The shift from the third Generation to 4G, in 2012, brought the speed up to 110 Mbps.  
Two years later, in 2014, with 4G Plus, videos could be downloaded at speeds of up to 225 Mbps and 11 cities in Italy have activated a service - with 3 carriers, meaning greater bandwidth than the initial 4GPlus bandwidth - to reach 300 Mbps.
To give an idea of the great improvement that has occurred over the last 5 years, we have compared the time it takes to download a normal film, of around 1GB, and a high definition film, of around 6 GB, depending on the network.
It has gone from 300 seconds in 2011 to 20 seconds today, in the former case, and from 25 minutes to 1 and a half minutes in the latter.

The underlying technology?
A combination of technical elements. First and foremost Carrier Aggregation, namely the possibility to use greater bandwidth uniting the 4G bandwidth portions available on different frequencies.
Then there are also new techniques for coding and modulating the frequencies and new mast transmission systems which, together, increase the transmission speed.
To take advantage of this technology you need the right mobile phone. For 4.5G, for example, the Sony Xperia XZ smartphone, capable of surfing at 500Mbps at peak speed.
In addition to Sanremo, the 4.5G network is gradually being extended to other cities, one of which is Turin, where our laboratories are located and where, in October last year, we tested a service that exceeded 500Mbps on a live data connection.
You could say that at TIM we have a “mania” for mobile technology: we are the second telecommunications company for the number of radio mobile patents in Europe, where we were the first to bring the services to 300 Mbps, in December 2015, and now the 4.5G network. Moreover, we are working to achieve one Gigabit per second with the 5G network, our next goal.
