3G Licensing Crucial Dates in Russia

• 23 October 2006 - the State Committee on Radiofrequencies made a decision to allocate frequency bands of 1935-1980 MHz, 2010-2025 MHz and 2125-2170 MHz for IMT-2000/UMTS mobile networks deployment on the Russian Federation territory.

• 26 December 2006 - the Federal Communications Agency announced tender rules for getting licenses to provide 3G services in Russia.

• 20 April 2007 – ICU President A.E.Krupnov announced the winners on 3G tender on operators activity licensing in IMT-2000/UMTS standard networks :

MegaFon , Mobile TeleSystems and VimpelCom .

• 24 May 2007 – 3G licenses issuing to winners by the RF Minister L.D.Reiman

OPERATOR’S PLANS• Mobile TeleSystems plans to launch HSDPA 3G services in

the largest cities of Russia in the beginning of 2008. It’s going to build 3000 base stations. MTS plans to invest $1bn over 3 years: till 2009 - in 45 cities and till 2011 – 11 mln. 3G subscribers

• VimpelCom plans to launch 3G services in Moscow in 2008. It’s going to build 6000 base stations over 5 years. VimpelComplans to invest $300-350 mln. in 2007-2008 in 39 constituent territories of the Russian Federation.

• MegaFon is expected to start construction of its new network since the end of 2007. It plans to invest $1bn over 3 years.

Operators Risks while Networks Deployment

Big variety of 3G terminals

Big international experience in

problems solving

No need for a subscriber to choose from «Empty List»

Operators risks for 3G networks

deployment are significantly lower then for WiMAX

Resume� The most perspective way of wireless access networks development is the

convergence with the cellular and fixed networks

� Convergent development of wireless access, cellular and fixed networks promote the efficiency increase of networks resources usage and radio-frequency spectrum, facilitate the development of new infocommunication services market and make them more available

� ICU’s proposals approved by the Scientific & Technical Council of the RF Telecom Ministry are the basis for the further development of state regulation in the communication sphere

� R&D “Cell-Access”: first but significant steps to implementation of the convergent networks in Russia

� Researches results realization will contribute to innovation development of telecommunication sphere, population involvement into the world information community
