Why do We need broadband access?

• New services require broadband access• Convergence of services• Development of distance working and

education• Development of interactive video, gaming

and other entertainment services• Access to Internet and other data

communication networks is becoming cheaper

Broadband access technologies

1. access based on copper cable

2. access based on optical fiber

3. wireless access


20


1.1. access based on copper cableaccess 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.


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


22

Characteristics of xDSL technologies


23


2. access based on optical fiber2. 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.


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


25


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.


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


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
