  • Publication number: 20190173583
    Abstract: A system for enabling signal penetration into a building includes a first transceiver, located on an outside of the building, for transmitting and receiving signals at a first frequency outside of the building, wherein the signals at the first frequency do not easily penetrate into an interior of the building. A first up/down converter converts between a first version of the signals at the first frequency and a second version of the signals at a second frequency. The first frequency is higher than the second frequency and the signals at the second frequency better penetrate to the interior of the building and overcome losses caused by penetrating into an interior of the building. A second up/down converter converts between the second version of the signals at the second frequency that overcomes the losses caused by penetrating into the interior of the building and a third version of the signals after transmission from the building exterior to the building interior.

  • Publication number: 20190166506
    Abstract: A unified core network provides core network services to a number of telecommunications network operators. The unified core is partitioned into a number of slices with each slice being the core network for a network operator. Each network operator is then free to define services within its own partition to serve its own users. In this manner, the network operators are freed from building and maintaining a core network while simultaneously enjoying the benefit of having a core network.
