4G is the fourth generations technique for mobile network. With 4G units with a 4G receiver (a SIM card) can reach internet, telephony and text in a speed of 100 mbit/s to stationary units. To stationary units the max speed is 1000 mbit/s. For mobile units the max speed is 100 mbit/s.
The first commercial mobile network with 4G was introduced in Oslo and Stockholm in 2009. Thereafter it spread to large parts of the world. 4G was however not as big and revolutionary as the update from GSM to 3G. 3G is 40 times faster than GSM while 4G is only 10 times faster than 3G.
The quality of calls with 4G is much better than 3G. To be able to stream content such as podcasts and videos directly in your phone is no big deal with 4G because the speed allows much faster buffering of the content. Today’s mobile phones are developed to offer energy saving for 4G.
- 4G is the fourth generations mobile network for mobile units.
- The first commercial 4G networks were introduced in Stockholm and Oslo.
- 4G+ was introduced in Sweden during the summer of 2016.
- 4G requires units that have a receiver for the 4G network.
- The best use of 4G is for mobile broadband.
- Sweden has one of the most expanded 4G networks.
- 4G offer among others better sound quality in calls.
4G for mobile broadband
To be able to connect to 4G it requires a unit that has a 4G receiver. The service that you’re subscribed to also needs pertain to 4G. The mobile users that stream podcasts, videos and other content directly from internet are those who will have utility of 4G.
4G has therefore had its’ breakthrough in mobile broadband because the speed is faster and of more use than in your mobile. In addition, 4G will be upgraded so that the speed and technique become more reliable. The expansion of 4G in Sweden is relatively big, outside of big cities.
4G+ is a further expansion of the fourth generation’s mobile network. In the summer of 2016 it was released in Sweden for the first time and means an improvement in form of quality and reliability. It’s mostly the connection that will improve. However, not all 4G receivers can connect to 4G+.
Soon to be surpassed by 5G
4G was a huge step from 3G in regards to downloading large amounts of data as fast as possible. It did however take a while until 4G mobiles and 4G reciprocal units were launched on the market. The same goes to say for the 4G expansion but today the majority of Sweden’s population have access to 4G networks.
The development of 5G is meanwhile really caught speed and is expected to launch year 2020 in Sweden – If not earlier in Stockholm. This means that 4G as established technique for the mobile network will soon be obsolete because 5G will be 100 times faster than the theoretical max speed for 4G (that doesn’t even exist commercially).
4G will however still coexist with 5G for a long time due to the restricted use of 5G during the transition period. It’s moreover just advanced things such as self-sufficient cars that will need to connect to the 5G network for the time being. Therefore 4G will soon completely replace 3G.Glossary
