In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 ...
5G is a major phase of mobile telecommunications standards beyond the 4G/IMT Advanced standards. NGMN Alliance or Next Generation Mobile Networks Alliance define 5G network requirements as: Data rates of several tens of megabits per second (Mbit/s) should be supported for tens of thousands of users.
In 4G systems, the circuit-switched infrastructure is abandoned and only a packet-switched network is provided, while 2.5G and 3G systems require both packet-switched and circuit-switched network nodes, i.e. two infrastructures in parallel. This means that in 4G traditional voice calls are replaced by IP telephony.
In telecommunication, a public land mobile network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country. [1] [2] A PLMN typically consists of several cellular technologies like GSM/2G, UMTS/3G, LTE/4G, NR/5G, offered by a single operator within a given country, often referred to as a cellular network.
Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-7 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
Specific requirements of the IMT-Advanced report included: Based on an all-IP packet switched network. [4]Interoperability with existing wireless standards. [5]A nominal data rate of 100 Mbit/s while the client physically moves at high speeds relative to the station, and 1 Gbit/s while the client and station are in relatively fixed positions.
