  • Patent number: 11711780
    Abstract: A base station is disclosed, comprising: a processor; a memory coupled to the processor; a base station access radio coupled to the processor; a user equipment module, coupled to the processor, for providing a backhaul link for the base station; and a sniffing circuit coupled to the processor. The sniffing circuit further comprises: a radio receiver coupled to an amplifier and a filter, the amplifier and the filter both capable of being used across a plurality of frequencies; and a baseband processor coupled to the radio receiver, configured to convert a received signal from the radio receiver to a baseband frequency, to determine whether the received signal is one of a 2G, 3G, 4G, Wi-Fi, or 5G signal, to measure a signal strength of the received signal, and to identify a synchronization signal within the received signal.

  • Publication number: 20200401675
    Abstract: Described herein are systems and methods for providing software provisioning of functionality in a wireless communications device. Software-enabling functionality may include systems for granting a license to intellectual property or other pre-embedded functionality within a device. Communications to and from the device may be used to send or receive activation messages and/or licensing messages. Network capabilities may be provisioned using activation messages sent over the network. Activation messages may be sent in-band or out-of-band, for a device connected to the Internet and/or a mobile operator core network. Licenses may be required for any functions or intellectual property present on a given device. Activation may enable logical modules of a system-on-chip (SOC), functions of a software-defined radio (SDR), baseband, or DSP core. The disclosed systems and methods could thereby provide a new, flexible paradigm, namely, “Silicon as a Service (SaaS).
