Analysis was carried out of the status and the development potential for the most informational closed market of professional mobile communications (PMR) and for the corporate mobile communication market closely related to the former. It was concluded that the potential of the market was considerably high but, at the same time, could not be used by applying the technologies that are operated at present. It was shown how advancing the McWILL standard developed on the basis of TD-SCDMA and included in the ITU. Recommendations would solve technical and commercial problems of Russian corporate and departmental users in getting access to PMR services.

A parametrical model, that adaptive antenna array and adaptive radio channel resource special distributing algorithms describes on common position, for McWILL Base Station are proposed. On it base composite parametrical criterion is offered. This criterion permits to determine in quantity the best characteristics for antenna array and for radio resource spatial distribution adaptive algorithm. Achieving advantages for such antennas and adaptive algorithms combinations are obtained. These advantages show significant higher rate over widespread in radio networks fixed three-sectors site structure.
Keywords: circle adaptive antenna array, mobile networks, spatial selection.

In this paper we based on the maximum likelihood (ML) criterion and derive an estimation algorithm for ICI components. After that we derive an equalizer scheme, which performs ICI rejection and fading correction. Modeling results have demonstrated that it should be possible to increase subscriber’s movement speed by a factor of 2−2,5 without service quality degradation in the LTE and McWILL networks. It was established, that when McWILL networks working in its basic bands has 3 times higher subscribers speeds upper limit then LTE networks in its basic bands.

EVALUATION OF MOBILE SUBSCRIBERS' MOVEMENT SPEED AFFECTING TO THE CONNECTION-LOSS FLOW INTENSITY IN NETWORKS WITH OFDM SIGNALS
A.O. Shorin, LLC «NXTT», technical director; as@nxtt.org
Relationships between subscribers' movement speed and the connection-loss flow intensity were obtained for communication systems with OFDM signals. It was found out that most height intensity of losses flow appeared in the lines with most complicated modulation types (QAM64). It is shown, that for the simplest modulation types (QPSK) impacting of subscriber’s movement are not strong. Also has been shown, that for basic McWILL bands 300…400 MHz there are not significant influence at drop calls intensity from movement with speeds less than 100 m/s. At the same time has been shown, that for basic LTE band 2600 MHz drop call rate unacceptably increases on subscriber’s speeds 30 m/s or higher.
Keywords: flow intensity, mobile communication systems, OFDM, movement speed, Markovian process.
MIMO: OPTIMIZATION FOR NUMBER LOGICAL CHANNELS CONTROLLING
G.O. Bokk, LLC «NXTT», science director, Dr.Sci.(Tech.); bokkg@yandex.ru
In the general framework of approach of the spatial-temporal processing of radio signals, which called MIMO, was performed the analysis of the effectiveness of controlling the number of logical channels in the presence of a reverse control channel. In the form of a fairly simple algorithm was found a rigorous solution of the nonlinear equation for the optimal number of logical channels. It is established that in the bands below 800 MHz well-known algorithms used in LTE, lose their effectiveness. In such cases, the most effective is the algorithms spatial focusing of the beam of the antennas, which currently supported only in the networks of standard McWILL.
Keywords: MIMO, adaptive performance, Shannon capacity.
