Acronyms and Definitions

Computer Engineering – the branch of engineering that integrates electronic engineering with computer sciences. Computer engineers design and develop computer systems and other technological devices.  (www.livescience.com/48326-computer-engineering.html)

Russian School of Mathematics – an after school program that provides mathematics education for children attending K–12 of public and private schools. The school provides children the opportunity to advance in mathematics beyond the traditional school curriculum. The founder of RSM is Inessa Rifkin and co-founder is Irene Khavinson (wikipedia)

GSM – Global System for Mobile Communications – a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets. (wikipedia)

GPRS – General Packet Radio Service – a packet oriented mobile data standard on the 2G and 3G cellular communication network’s global system for mobile communications(GSM). GPRS was established by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP). (wikipedia)

3GPPThe 3rd Generation Partnership Project – unites [Seven] telecommunications standard development organizations (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC), known as “Organizational Partners” and provides their members with a stable environment to produce the Reports and Specifications that define 3GPP technologies. The project covers cellular telecommunications technologies, including radio access, core network and service capabilities, which provide a complete system description for mobile telecommunications.

Fact Check

When did wireless come to Brazil? The history of mobile telephony in Brazil began on 30 December 1990, when the Cellular Mobile System began operating in the city of Rio de Janeiro, with a capacity for 10,000 terminals. At that time, according to Anatel (the national telecommunications agency), there were 667 devices in the country. The number of devices rose to 6,700 in the next year, to 30,000 in 1992. In November 2007 3G services were launched, and increased rapidly to almost 90% of the population in 2012 and the agreements signed as part of the auction specify a 3G coverage obligation of 100% of population by 2019. After the auction that took place in June 2012, LTE tests were undertaken in several cities, tourist locations and international conference venues.[5] The first LTE-compatible devices became available in the local market and LTE services was commercially launched in 2013. Under the 4G licence terms, operators were required to have commercial networks in all twelve state capitals which are acting as host cities for the 2014 FIFA World Cup. (wikipedia)

Claude Shannon – (April 30, 1916 – February 24, 2001) was an American mathematicianelectrical engineer, and cryptographer known as “the father of information theory“. Shannon is noted for having founded information theory with a landmark paper, “A Mathematical Theory of Communication“, that he published in 1948. He is also well known for founding digital circuit design theory in 1937, when—as a 21-year-old master’s degree student at the Massachusetts Institute of Technology (MIT)—he wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical numerical relationship. Shannon contributed to the field of cryptanalysis for national defense during World War II, including his fundamental work on codebreaking and secure telecommunications.
