An apparatus and method are provided for dynamically changing power distribution levels to sectors in a cell site. A device, such as an eNodeB, radio network controller, or base station controller, provides instructions to an RF power splitter to adjust the power output in ratios, which changes the power distribution levels at the sectors. The power splitter contains a transformer and motor that can dynamically change the power output ratios based on the instructions received from the device. The resulting power outputs are distributed to the sectors.

A method, system, and medium are provided for dynamically enabling and disabling cyclic prefix within a long-term evolution (LTE) channel. A base station receives channel quality indication (CQI) reports indicating levels of ISI within the LTE channel. The base station determines whether the levels of ISI within the LTE channel are greater than, equal to, or less than a predetermined threshold level of ISI for the LTE channel. Based on the determination, the base station either enables or disables cyclic prefix within the LTE channel. In addition to levels of ISI, numbers of roaming users or cell edge users utilizing the LTE channel may affect whether cyclic prefix is enabled or disabled within the LTE channel.

An antenna mount for mounting radio antennas on a communications tower is described. The antenna mount includes a ring structure that encircles the tower and includes a channel disposed about its outer perimeter. The channel is configured to receive a plurality of antenna carriages upon which antennas are mounted on a first end. A second end of the antenna carriage is disposed in the channel and is slideably movable along the length of the channel about the perimeter of the ring structure. The antenna is thus aimable in any desired azimuthal direction by moving the antenna along the ring structure. Bands for communication of data, power, control signaling, and propulsion of the antenna carriages about the ring structure are disposed in the channel. The ring structure may include a junction that allows reorientation of antennas with respect to one another.

Systems, methods, and computer-readable media for modifying signals are provided. Embodiments include staged low noise amplifiers (LNA's) in order to customize signal modification. Signals may be modified at various fixed gains by different LNA's within a device. Additionally, signals may be attenuated or receive no modification at all in order to ensure signals are within a preferred signal range.

Systems, methods, and computer-readable media for dynamically adjusting power settings based on a gain mapping file are provided. In embodiments, the method includes receiving and interpreting a gain mapping file associated with an antenna. Transmit power levels are determined for each channel associated with the antenna. Transmit power levels are adjusted according to the determination and each channel is adjusted to have identical gain.

A method and system are provided for dynamically changing Qrxlevmin and Sintrasearch values in a LTE network. An eNodeB sets the Qrxlevmin and Sintrasearch values for each mobile device. The Qrxlevmin value and Sintrasearch value are changed based on RF conditions and a velocity of the mobile device. A lower Qrxlevmin value coupled with a higher Sintrasearch value increases a search period to locate better performing neighboring cells and reduces the chance of handing down from the LTE network to a non-LTE network.

Systems, methods, and computer-readable media for optimizing voice services are provided. Hybrid automatic repeat request (HARQ) is an algorithm that implements fast retransmissions of lost blocks or packets of data. HARQ is an error correcting algorithm. Data may be lost at any layer of a protocol stack, thus, increasing a retransmission rate. In order to reduce the retransmission rate and increase quality of voice services, HARQ may be implemented at each layer of a protocol stack based on, for example, radio frequency signal and retransmission rates.

Optimizing voice services

A method and system are provided for dynamically adjusting gain in a cell site. Network devices, such as an eNodeB, NodeB, base transceiver station, base station server, radio network controller, and base station controller can provide instructions directly or through remote radio heads to an amplification system to change the power distribution levels. The instructions are received over an AISG protocol and cause a mechanical motor in an amplification system to move a magnetic core in a solenoid causing a change in the electromagnetic field resulting in a change in an electrical current. The change in the electrical current causes a change in gain, thus, resulting in a change in the power distribution level in a cell.
