The first handheld mobile phone was demonstrated by John F. Mitchell [1] [2] and Martin Cooper of Motorola in 1973, using a handset weighing c. 4.4 lbs (2 kg). [3] In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion, penetrating 100% of the global population and reaching even the bottom of the economic pyramid . [4] In first quarter of 2016, the top smartphone manufacturers were Samsung , Apple , and Huawei (and "[s]martphone sales represented 78 percent of total mobile phone sales"). [5]

In 1991, the second-generation ( 2G ) digital cellular technology was launched in Finland by Radiolinja on the GSM standard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators.

Ten years later, in 2001, the third generation ( 3G ) was launched in Japan by NTT DoCoMo on the WCDMA standard. [7] This was followed by 3.5G, 3G+ or turbo 3G enhancements based on the high-speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity.

Espionage (colloquially, spying ) is the obtaining of information considered secret or confidential without the permission of the holder of the information. [1] Espionage can be committed by an individual or a spy ring (a cooperating group of spies), in the service of a government or a company, or operating independently. The practice is inherently clandestine , as it is by definition unwelcome and in many cases illegal and punishable by law. Espionage is a subset of " intelligence " gathering, which includes espionage as well as information gathering from public sources.

Espionage is often part of an institutional effort by a government or commercial concern. However, the term is generally associated with state spying on potential or actual enemies primarily for military purposes. Spying involving corporations is known as industrial espionage .
