摘要： 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.

摘要： A spread spectrum communications system that is operable to provide user-selectable data transfer rates comprises a user station for generating an access request and a gateway server for receiving the access request. The gateway server includes a rate unit for comparing a requested rate to assigned rates, a selector for selecting an available user channel and an available signaling alphabet, and an allocation unit for assigning the carrier, user channel, and alphabet to the access request. One of several offered transfer rates is assigned to the available user channel. Each offered rate corresponds to a set of signaling alphabets with low cross-correlation for data transfer.

摘要： 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.
