OREANDA-NEWS. August 30, 2010. Kuanyshbek Yessekeyev, Chairman of the Board of Kazakhtelecom JSC presented to the Head of state broadband Internet access services using EV-DO technology within the working trip of the President of Republic of Kazakhstan to Kostanay oblast, reported the press-centre of Kazakhtelecom.

Organization of broadband Internet access in rural area is seconds stage of the project on organization of wireless communication network on base of CDMA-450, which is included to the number of breaking ones and is realized within the state Program “30 corporate leaders”. In result of project realization, deficiency for communication in rural area will be completely eliminated. Created network of wireless access will allow solving information inequality problem between rural and municipal residents.

By results of the first stage on implementation of wireless communication on rural network, all perspective rural settlements of RK are telephonized, 392 base stations have been installed, 232 thousand rural subscribers have been connected, density of telephone lines reached 13.6 to 100 residents in rural area, number of subscribers in rural area in April the same year exceeded 1 million people. Network coverage composes over 60% of the republic territory.

EV-DO (Evolution-Data Optimized) standard has been worked out to increase Internet access speed, which is realized on base of third generation cellular networks CDMA 2000 and represents its original raising over the existing CDMA networks, which allow providing broadband Internet access services to subscribers without attachment to land telecommunication channels. New technology allows increasing quality of Internet access at expense of high data transfer. Maximum allowed Internet access speed composes to 3 MB/s, medium speed composes 600 KB/s, that corresponds to third generation communication standards (3G). High speed of data transfer by EV-DO technology in rural area reached at expense of applying new algorithms of digital data compressing that allows securing high speed Internet access at any point of CDMA-450 coverage zone. In Kostanay oblast the pilot project on EV-DO implementation is realized in 3 districts at the same time: Kostanay, mendykarinsky and Sarykolsky.

Information
CDMA Standard (Code Division Multiple Access) is digital and uses frequency band in a range of 450 MHz, has multi station access technology with code channels separation. Coverage zone of CDMA-450 base station in rural area composes 25-35 km. One such station can maintain up to 1000 subscribers. Equipment of wireless communication CDMA is recommended by international organization on communication standardization as most perspective for building third generation networks.
