Abstract: Provided are methods and systems of managing vertical handoffs in a wireless communication network. Embodiments include analyzing wireless device usage to determine usage patterns, which may include locations and times at which the wireless device is typically accessing the network. The network may recognize points in the usage patterns at which signal quality parameters are typically reduced. Such reductions in signal quality parameters may lead to inefficient vertical handoffs. The network may decrease adverse effects of inefficient vertical handoffs by reducing ping ponging, selecting links between wireless devices and network nodes, or indicating to a user of the wireless device that delays and/or data loss may occur.

Abstract: Provided are methods and systems of using division-free duplexing (DFD) in a cable communication network. Techniques for applying DFD in a cable communication network may enable data to be transmitted and received over a coaxial cable without using division duplexing techniques. For example, the cable communication network may include DFD enabled network nodes and each subscriber to the cable network may be equipped with a DFD system configured to operate in a DFD mode. In some embodiments, oppositely propagating signals may be transmitted over one frequency channel, and DFD techniques may be used to recover originally transmitted signals. Further, in some embodiments, DFD techniques may be used with encryption methods to increase the security of data transmitted in the cable communication network.

Abstract: A smart street lighting system and method employs a plurality of street lights having a luminaire, a luminaire associate and a support pole. A communications module is contained within the luminaire associates and a power line is contained within the support poles. The power line is coupled to the communications module, the luminaire associate and the luminaire, and a steerable millimeter wave radar operatively coupled to the communications module. The communications module operates in a radio frequency network in a frequency range of 57-64 GHz. The steerable millimeter wave radar provides a signal reflected from a target that may be received by one of the luminaire associates within the system. A powerline communications system interfaces with the radio frequency network to provide communications between the communications modules in the street lights and the PLC system.
