Aim of investigation: research of possibility of multiplying efficiency of the use of frequency resource for technology of CDMA-450, which will be instrumental in successful integration of Ukraine in the European communication network and outer informative space in part of the effective use of radio frequency resource. Results: the problems of possibility of expansion of frequency resource are explored for development in Ukraine of technology of CDMA EV-DO, which works in a bar 450 MHz, and developed recommendation in relation to expansion of frequency resource in a bar 450 MHz under technology of CDMA EV-DO. Effectivity: it is shown that expansion of frequency resource for development in Ukraine of technology of CDMA EV-DO possibly taking into account the developed recommendations. Sphere: technologies of radio contact.
