The end of 2G and 3G networks, the end of an era in the mobile industry
Recently, the global communications standards organization 3GPP announced that at the recent RAN #88e plenary meeting, the RAN6 working group responsible for GERAN and UTRAN wireless and protocol work was officially closed.
It is reported that the RAN6 working group is mainly responsible for studying 2G and 3G wireless functions, and defining specifications and interfaces involving GSM/EDGE radio access network (GERAN) and UMTS radio access network (UTRAN).
In fact, as early as 1998, standard setting organizations from Europe, China, Japan, South Korea, and North America jointly established 3GPP (Third Generation Partnership Organization) to jointly develop detailed next-generation mobile communication network (3G) standards.
At the same time, 3GPP has also accepted the work of maintaining and continuing to develop GSM specifications. The project successfully promoted the evolution from 2G to 3G, and successfully realized the global popularization of 3G.
Although 2G and 3G are still in use at present, it is time to focus the energy of standards organizations on the next generation of mobile communication technology.
With the evolution from 4G to 5G, the GERAN and UTRAN standards and the core networks behind them are completely stable and can be used for a long time if needed.
3GPP also stated that the closure of the RAN6 working group marks the end of an era in the mobile industry.
But this does not mean that 2G and 3G networks will completely withdraw from the stage of history. They will still be maintained as needed, but they will no longer be developed and evolved.
Finally, 3GPP successfully promoted the evolution of global mobile communications from 2G to 3G, realized the global popularization of 3G, and finally step by step to 4G and 5G.
Cell phone jammer can shield 2/3/4/5G signals, GPS, WiFi, drones and other signals. They are mainly used in prisons, schools, churches, gas stations and other places to provide you with shielded communication services to protect your privacy Safety!
