Abstract: Systems and methods for platform independent secure customer data migration from one data storage to another data storage. A synchronization server includes a translation layer and an authentication layer. The translation layer encodes data from one data storage access language and schema to another distinct data storage access language and schema. Before the full transition to the second data storage, the translation layer also encodes, updates and inserts data into the first data storage. Existing references to the first data storage as well as new references to the second data storage are supported using an authentication layer. After a request for secure customer data, a determination is made which data storage is accessed from an obtained authentication factor. When the second data storage is accessed, the translation layer is employed to encode the first data storage object references to the corresponding second data storage object.

Abstract: A communication device includes a donor receiver that receives a first beam of input radio frequency (RF) signals from a base station or a network node. The communication device further includes a service transmitter that transmits a second beam of RF signals in a first radiation pattern to a user equipment (UE). The communication device further includes control circuitry that detects an amount and a direction of echo signals at the donor receiver. The control circuitry applies polarization to the second beam of RF signals transmitted to the UE and calibrates the polarization to minimize the echo signals at the donor receiver. A second radiation pattern is generated for the second beam of RF signals and communicated to the UE based on the calibrated polarization. The communication of the second beam of RF signals in the generated second radiation pattern further reduces the echo signals at the donor receiver.
