  • Patent number: 8693875
    Abstract: A system and method for optimizing an optical RF photonic link system is presented. The system comprises a modulator subsystem in which nonlinear response is compensated by an envelope precompensation method and employs an optical filter to suppress optical carriers and extract modulated sidebands, an optical amplifier, and an array of photodetectors, each having a plurality of pairs of diodes. The modulator subsystem performs optical filtering on the signal, the signal is amplified by the optical amplifier and sent to the array of photodetectors. The optical amplifier can be an erbium doped fiber amplifier, or a phase sensitive amplifier. The optical power can be delivered to each diode of the array of photodetectors via a photonic integrated circuit.

  • Publication number: 20130094444
    Abstract: A method for automatically provisioning a WiFi-equipped machine-to-machine (M2M) device is disclosed. A WiFi M2M gateway identifies a WiFi network identifier broadcast by a powered-on M2M device in WiFi ad hoc mode through a scanning procedure and joins the ad hoc network defined by the M2M device. The WiFi M2M gateway obtains device information (e.g., MAC address) of the M2M device. The WiFi M2M gateway transmits a command to the M2M device to switch from ad hoc mode to infrastructure mode. The WiFi M2M gateway registers the M2M device with an M2M server associated with a service provider based on the device information of the M2M device. The WiFi M2M gateway receives a fully qualified domain name (FQDN) associated with the M2M device from the M2M server.
