It is a term used in the telecommunication sector. It is a spectrum that supports 2G technology. High bandwidth is required for this purpose.

"2G" means second-generation wireless telephone technology. 2G cellular telecom networks were commercially launched on the GSM standard in Finland in 1991.

"G" has been superseded by newer technologies, such as 2.5G, 2.75G, 3G, and 4G; however, 2G networks are still used in many parts of the world.

There are three primary benefits of 2G networks over their predecessors: phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.
