2G (or 2-G) is short for second-generation cellular network. 2G cellular networks were commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. Three primary benefits over their predecessors were: Digitally encrypted phone …

3G is the third generation of wireless mobile telecommunications technology. It is the upgrade for 2.5G GPRS and 2.75G EDGE networks, for faster data transfer. This is based on a set of standards used for mobile devices and mobile telecommunications …

4G is the fourth generation of broadband cellular network technology, succeeding 3G, and preceding 5G. A 4G system must provide capabilities defined by ITU in IMT Advanced. Potential and current applications include amended mobile web access, IP telephony, gaming services, …

In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones.5G networks are …

In telecommunications, 6G will be the sixth generation standard for wireless communications technologies supporting cellular data networks. It is the planned successor to 5G and will likely be significantly faster, at speeds of ~95 Gbit/s. Like its predecessors, these networks …

Alternating Current (AC)

Circuit that passes an AC signal while blocking a DC voltage.

A voltage with alternating polarity.

Equipment that will operate from an AC or DC power source.

Active components, or Active Parts rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition. Active components …
