14 World Broadband statistics Share of world broadband subscribers by region in Q South and East Asia; 20,91% Western Europe; 26,82% Asia-Pacific; 16,49% North America; 23,31% Middle East and Africa; 2,54% Latin America; 5,23% Eastern Europe; 4,70% 14

15 World Broadband statistics Share of broadband technologies in Q DSL; 65,19% Cable Modem; 21,95% Other; 2,05% FTTx; 10,79% 15

18 Using of Broadband technologies in CIS V.92

19 Broadband access technologies 1. access based on copper cable 2. access based on optical fiber 3. wireless access 19

20 Broadband access technologies 1. access based on copper cable one or several copper pairs are used between subscribers and operators. The best example of this is the plain old telephone system (POTS) where the customer is physically connected to the operator by a pair of twisted copper cable. Most popular technologies are different types of DSL such as ADSL, HDSL, SHDSL, VDSL etc. 20

21 Advantages & Disadvantages DSL simultaneously keeps your Internet connection and phone lines open You can have higher speeds than you would have with a regular modem (1,5 Mbps<) DSL uses the existing wiring infrastructure of your telephone lines DSL efficiency is related to distance DSL needs two copper pairs for developing HDSL and G.SHDSL technologies DSL is limited for a certain perimeter 21

22 Characteristics of xdsl technologies 22

23 Broadband access technologies 2. access based on optical fiber 2. access based on optical fiber this type of access is one of the effective method of access technologies, because of its possibility to transfer dates to long distances with VHS. 23

24 Advantages & Disadvantages very high speed variety of services simultaneously low prices of optical fiber very high operating costs difficulty of elimination of defects Lack of specialists 24

25 Broadband access technologies 3. wireless access subscribers and operators are connected through radio channels. Mobility is one of the significant benefits of this technology. Widespread wireless technologies such Wi-Fi and Wi-MAX are more used nowadays. 25

26 Advantages & Disadvantages mobility of subscribers simplicity of network operating more convenient for business limited spectrum of used frequency network security is lower than fixed networks limited number of users in one access point 26

27 Importance of broadband access for Uzbekistan one of the basic factors in building of e- Government development of distance working and education implementation of modern ICT services improvement of productivity making contribution to development of telecommunication infrastructures 27
