2G Connectivity

2G  connectivity refers to second-generation wireless telephone technology. Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. Three primary benefits of 2G networks over their predecessors were that 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. 2G technologies enabled the various mobile phone networks to provide the services such as text messages, picture messages and MMS (multi media messages). All text messages sent over 2G are digitally encrypted, allowing for…

1G Connectivity

1G refers to the first generation of wireless telephone technology in mobile telecommunications. The analog telecommunications standards that were introduced in the 1970s and continued until being replaced by 2G digital telecommunications.In the 1970s, the First Generation, or 1G, mobile networks were introduced. These systems were referred to as cellular, which was later shortened to “cell”, due to the method by which the signals were handed off between towers. Cellular phone signals were based on analog system transmissions, and 1G devices were comparatively less heavy and expensive than prior devices; 0G. The main difference between the two mobile telephone systems (0G and 1G), is that the radio signals used by 1G…

0G – Mobile Radio Telephone

Wireless connectivity just as any other inventions has a lot to be told. The mobile radio telephone technology or as it is also called 0G, refers to pre-cellular mobile telephony technology in the 1970s. Even though not as swift as today, they laid the foundations for the forthcoming generation of truly wireless mobile telecommunications. These mobile telephones were usually mounted in cars or trucks, though briefcase models were also made. Mobile radio telephone systems preceded modern cellular mobile telephony technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes referred to as 0G (Zero Generation) systems. Technologies used in 0G systems included PTT (Push…
