This is a timeline of mobile telephony, attempting to describe the evolution of mobile phone networks, as well as crucial mobile device releases in relation to novel functionality.

Big picture

Time period Development summary
1900s Radio transmission is achieved by creating bursts of sparks generated by electrical voltages.[1]
1930s The idea of a cell phone begins.[2]
1940s Communication by mobile radios becomes more common. Most government agencies, as well as the rich people, own mobile radios.[3] AT&T and Bell Labs introduce cellular technology. However, mobile phones would not develop widespread use at the time.[4] US Signal Corps communicate via radio in field during World War 2.[5]
1960s Researchers develop the technology systems (like frequency reuse and handoff) that would lead to modern cellular networks.[4] In the United States, Bell Labs prepares a detailed plan for implementing the cellular system.[6] Soviet engineer Leonid Kupriyanovich develops very small mobile phones.
1970s 1G is developed by AT&T and Bell Labs early in the decade.[7] The first mobile call is made.[8]
1980s 1G is deployed.[7][6] Mobile phone technology starts to be released commercially.[9] Adding text messaging functionality to mobile devices begins.
1990s Mobile telephony revolutionizes telecommunications during the decade.[10] 2G Second–generation wireless telephone technology becomes available, [11] bringing the first digital systems to be deployed.[9][7] Mobile phone operators start offering prepay mobile phones. European and American networks start to split apart and compete against one another.[4]
2000s Apple introduces the iPhone. Android operating system launches. 3G technology starts deployment.[7]
2010s A massive development in smartphone technology takes place. 4G technology starts deployment.[7] Mobile telephony keeps extending into developing and least developed countries. 5G technology is still in development phase as no standard for its deployment has been concreted.[12]

Full timeline

Year Event type Details
1876 (March 10) Antecedent Scottish-born Alexander Graham Bell, the inventor of the telephone, makes the first phone call.[8] United States
1894 Italian inventor Guglielmo Marconi transmits signals over the distance of 2 kms.[13]
1906 Antecedent Canadian-born inventor Reginald Fessenden manages to broadcast music through radio.[13] United States
1908 Antecedent A man claims to have invented a wireless telephone. Being considered so crazy for this time, he is accused of fraud. The charges are later dropped.[4]
1921 Antecedent The Detroit Police Department introduce mobile radios in their police cars, giving rise to the car–to–car radios. However, the system doesn't work very well at the time.[3][14] United States
1924 Network launch Wireless phones are tested on trains running between Berlin and Hamburg.[4] Germany
1940 Technology Second World War: Hand-held radio receivers become widely available, opening up communications in battlefields around the world.[4]
1945 Network launch The first service created just for mobile phones launches in Saint Louis, but the service doesn't work well and it does not last.[3][14] United States
1946 (June) Network launch American company Bell Labs begins to offer mobile telephone services on vehicles in Saint Louis. A few weeks later, AT&T matches Bell Labs, offering its Mobile Telephone Service (0G equivalent), at the time a wide range of mostly incompatible mobile telephone services with limited coverage areas and a small number of available channels.[4]
1946 Network launch Interconnection of mobile transmitters and receivers with the Public switched telephone network (PSTN) begins in the United States, with the introduction of Mobile Telephone Service (MTS) by the American Telephone and Telegraph Company.[15] United States
1947 Technology Engineers at Bell Labs seek ways to implement cell service in vehicles, theorizing that hexagonal cells would work best for them. The first car phone service is attempted. A car phone service opens between Boston and New York, but this service soon fails.[3] The same year, base stations for mobile phones come into being when engineers from Bell Labs develop the first stations.[4] United States
1947 Bell Labs is the first company to propose a cellular radio telephone network.[1][6] United States
1948 Service coverage The Mobile Telephone Service, initially only available in Saint Louis, becomes now available in about 100 towns in the United States. Using this service, an estimated 5,000 customers place approximately 30,000 calls each week. Each call has to be manually connected by an operator. The system also functions similar to a Walkie-Talkie: a button must be pushed down talk, then released to listen. The Mobile Telephone Service requires about 36kg of equipment in the vehicle. Expensive, it costs approximately US$ 15 per month (same buying power as $154.76 in 2017) plus an additional $0.30 to $0.40 per local call. [4] United States
