Mobitel is a Slovenian GSM/UMTS/LTE mobile operator. The company is under a 100-per-cent ownership of Telekom Slovenije. == Company history == Mobitel was established in October 1991〔(History )〕 as a limited liability company. The founder was SP PTT Ljubljana, which was joined by other Slovenian PTT companies by the end of the year. In November 1992, Mobitel was transformed into a public limited company. In 1991, the company already set up the NMT analogue network for mobile telephony in Slovenia. In 1994, PTT Slovenija separated postal and telecommunication activities and transferred the latter, together with the infrastructure, to the newly founded Telekom Slovenije, which became the owner of a 100-per-cent share of Mobitel. In 1995, Mobitel became the national operator of digital mobile telecommunications by the decree of the Government of the Republic of Slovenia. By the summer of 1996, the company thus built the base of the GSM network. In 1996, the company also became a member of the international GSM Association,〔(GSM World )〕 uniting GSM operators and GSM device manufacturers. The membership in the Association enabled the establishing of the first contracts on mutual roaming in foreign networks. By July 1996, the company provided a 40% GSM coverage of the population. By 2000, 1,000,000 users already used Mobitel services in the GSM and NMT networks. In November 2001, the company was the first in Slovenia to obtain a concession contract for UMTS – the third generation of mobile telecommunications. In addition to telephony, the existing network enabled also a series of additional services. In 2001, the company introduced GPRS data transfer, in 2002 the network started supporting MMS multimedia messages, since 2003, network users have been able to access multimedia content on the mobile portal (Planet ) and, in December 2003, Mobitel launched the UMTS third generation network, the first in the world. In 2008, the whole UMTS network was upgraded by the HSDPA and HSUPA technologies, also called 3.5 G. Currently the company is upgrading its network with the HSPA+ technology.〔http://tehnik.mobitel.si/trenutna-pokritost-slovenije-s-hspa-mobilni-internet-216-mbs/〕 In March 2013 Mobitel launched LTE network on frequency 1800 MHz, covering 27 cities with 93 cell sites (37,25% of population), expanding its coverage to 31 cities (39,75% of population) in April.〔()〕〔(LTE/4G )〕 By the end of 2013 Mobitel astimates they will have 250 operational LTE cell sites.〔()〕 In June 2014 Mobitel extended their LTE network by using the new awarded 800 MHz frequency.
