Abstract: A method is provided for using virtual subscriber identity modules (vSIMs) for client devices. A network device creates, in a memory, a user account for storing one or more vSIMs. The network device receives, from a user of the user account, a selection of network services to be associated with a vSIM. The network device initiates creation of a blockchain including a vSIM certificate for the network services, wherein the vSIM certificate includes an International Mobile Subscriber Identity (IMSI). The network device associates the vSIM certificate with the user account. The vSIM can be retrieved and used by any one of different devices associated with the user account or loaned to other users.

Abstract: A user equipment (UE) device may include a memory, a communication interface, a plurality of antenna components, and one or more processors. The one or more processors operate to identify a plurality of base stations available for connection via the communication interface and the plurality of antenna components. Virtual user equipment (UE) for two or more of the identified plurality of base stations are allocated and the UE device connects to the two or more base stations using the respective virtual UEs. Network characteristics are identified for the connections with the plurality of base stations. Data flows for the device are identified. The identified data flows are assigned to the virtual UEs based on the identified network characteristics.

Abstract: A user equipment (UE) device may include a memory, a communication interface, an antenna, and one or more processors. The one or more processors operate to identify a plurality of networks available for connection via the communication interface and the antenna assembly. Virtual user equipment (VUE) for two or more of the identified plurality of networks are allocated and the UE device connects to the two or more networks using the respective VUEs. Network characteristics are identified for the connections with the plurality of networks. Data flows for the device are identified. The identified data flows are assigned to the VUEs based on the identified network characteristics.

Abstract: A wireless signal at a low frequency is received at a face of a meta-material antenna. An offset carrier, at a high frequency, is received at an opposite direction face of the metal-material antenna. Passive mixers upshift the low frequency wireless signal to a high frequency, at the difference between the low frequency and the offset carrier. The upshifted version of the received low frequency signal is radiated from a second face of the meta-material antenna.
