ÑDMA - the system of multiply access with code
division - became, probably, most promising system which has appeared
in the world market. Decades ago this technology was used in military
connection (USA), and today is known for all as the global digital
standard for commercial systems of communications. According to
official Internet-site of the author of standard CDMA, company
Qualcomm from August, 28th, 2006, 224 operators of CDMA networks in
95 countries of the world provide services of communication to 324
million to subscribers.
In technology CDMA maintenance of high quality of speech is possible at
simultaneous decrease in radiated capacity and a level of noise. Result
is constant high quality of transfer of speech and data with the minimal
average target capacity.
In tens times smaller value of target capacity unlike other, now in use
standards - distinctive quality of technology CDMA by consideration of
two important factors:
Influences on an organism of the person;
Operation time without additional charge of the accumulator.
Capacity CDMA in three-six times exceeds capacity of other digital
systems. The networks constructed on its basis, effectively use a
radio-frequency resource, owing to an opportunity of repeated use
of one same frequencies in a network.Under quality characteristics of transfer CDMA speech parameters are
comparable to quality of wire channels. As on channels CDMA it is
transferred not only the voice, but also any other information,
special value has absence of handicaps.System CDMA provides a smaller delay in transfer of the voice message,
than other systems of mobile communication. This property gives side
benefits CDMA in conditions of cities with high-altitude buildings.Owing to the opportunities standard CDMA has officially been recognized
by world telecommunication community the standard of 3-rd generation of
wireless communication.
Considering all the above-stated positive factors, company ULTEL within
the limits of the first stage of project CDMA2000 1X, beginning from
01.09.2006 of year has commissioned the wireless network (ATS-480)
covering all territory of city Baku and peninsula Absheron.
