1-5G: a breakthrough technology: With 5G, a real technological breakthrough was born. The 3G and then 4G generations of mobile telephony are part of technological continuity. Each new generation was an evolution of the previous one.
2-5G will offer an increased throughput and very low latency, close to optical fiber. Speeds equivalent to the optical fiber, around at least 100 Mbit / s on average perceived by the user, and up to 20 Gbit / s at least in theory. 5G must be able to offer a user speed and a maximum speed respectively 10 and 20 times higher than what is currently available with 4G.
3-With 5G, the end of “network neutrality”: 5G is based on the principle of slicing, which consists of “slicing” the network to allocate dedicated resources by type of use. There will be priorities to manage. 4-5G will be operational normally with gear speeds of 500 km / h (ex TGV). 5-Latency: 4G + is approaching 10 milliseconds. In 5G, this would be reduced to less than a millisecond. 6- 5G is a network that will also be dedicated to the Internet of Things. 7-Energy savings, since 5G should save the batteries of our devices. 9-The bit rate depends on the frequency band used: The larger the band, the higher the bit rate. Regarding LTE, it uses a band of 20 MHz at most, which allows for a throughput of 150 Mbit / s. By aggregating 5 carriers, the total band reaches 100 MHz, so the throughput can be 5 times higher. In 5G we will need an 800 Mbit / s band.
10- There are 2 ways to deploy 5G radio:non-standalone mode (NSA) and standalone mode (SA). In NSA mode, 5G interacts with the 4G core. To deploy 5G in SA mode, a 5G core network is required. René Serres is a telecom and ICT consultant.
