A two-way terrestrial antenna, employing electrical down tilt and azimuth beam adjustment capability is disclosed. Such antenna configuration allows for a variable antenna coverage footprint within designated coverage sector. To compensate for installation support structure variations the two-way antenna employs a positional sensor that can provide feedback to BTS or automatically compensate azimuth and tilt beam angles so as to provide uniform sector coverage. In particular by monitoring tri-vector gravitational inclinometer and earth magnetic field sensors, and determining correction factors for antenna tilt and azimuth beam adjustments, uniform or compensated sector coverage is provided.

The invention relates to a self-optimization method for a concentrated clustering type self-organization network (SON), belonging to the field of digital communication. The method comprises the following steps of: gathering cells with stronger relativity into a cluster, arranging SON entities in the cluster and a network management center, coarsely adjusting each cluster firstly, determining whether the parameter such as antenna tilt, antenna azimuth or downlink transmission power of each cell in the cluster needs to be adjusted, and if the parameter needs to be adjusted, outputting a parameter adjusting instruction; adjusting relevant parameters of the corresponding base station in the cluster; after coarse adjustment, computing the capacity and coverage indexes in the cluster by the SON entity in each cluster according to the adjusted parameters; and inputting the capacity and coverage index parameters in each cluster into a SON control ring of the network management center by the network management center, then evaluating the integral capacity and coverage indexes of each cluster, and determining whether to finely adjust the relevant parameters of all base stations in the corresponding clusters. In the invention, coarse adjustment and fine adjustment are carried out sequentially, thereby better achieving global optimization.

Using High-beam and low-beam transmission signals that have different antenna tilts, different beam-widths, and different polarizations than one another may provide performance advantages in wireless networks. The high-beam transmission signal and the low-beam transmission signal may have orthogonal polarizations. For example, the high-beam transmission signal and the low-beam transmission signal may be linearly polarized signals having different electromagnetic field (E-field) polarization angles with respect to the y-axis, e.g., + / − forty-five degrees with respect to a vertically polarized wave. As another example, the high-beam transmission signal may be a vertically polarized signal, and the low-beam transmission signal may be a horizontally polarized signal, or vice-versa. In addition to having orthogonal polarizations, the low-beam transmission signal may have a greater antenna beam down-tilt angle, and a wider beam-width than the high-beam transmission signal.

Optimization of a wireless communications network may be accomplished by evaluating relationships between a source cell and a plurality of target cells, determining an optimization value based on the evaluated relationships, and adjusting an antenna parameter of the source cell based on the optimization value.

Embodiments are directed towards providing 5G zero touch traffic management of cells in a network. A target cell associated with a network objective is identified. One or more neighbor cells are also identified. Transmit power and tilt capabilities of the target cell are determined. An interference between the target cell and the one or more neighbor cells is also determined. An electrical antenna tilt adjustment or a transmit power adjustment is determined for the target cell to apply based on the transmit power capabilities, the tilt capabilities, the interference, and the network objective. The determined electrical antenna tilt adjustment or the determined transmit power adjustment are then provided to the target cell. If the network objective is met after the target cell applies the electrical antenna tilt adjustment or the determined transmit power adjustment, then the changes are confirmed, otherwise they are reversed.
