    • In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. Furthermore, varying distances between mobile units and the BTS, as well as Rayleigh fading, caused by destructive interference effects between direct and reflected signals, create extreme signal strength variations in the initial uplink signal from the mobile stations. The use of spatially-diverse antennas for receiving uplink signals provides diversity gain and mitigates deep fades. Furthermore, selecting the stronger of the spatially-diverse uplink signals mitigates deep fades and reduces frequency usage in the backhaul frequency band. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band translators include delay elements to implement slot-by-slot selective spatial diversity and automatic level control in a predictive feedforward fashion. The selective diversity mitigates deep Rayleigh fades, while the dynamic automatic level control drastically reduces the uplink backhaul dynamic range to allow for greater backhaul distances. Predictive feedforward automatic level control also eliminates overload and saturation of the backhaul high power amplifier, normally caused by wide variations in uplink power levels.
    • 在传统的时分多址(TDMA)无线系统中,由于时隙同步约束,移动单元与基站收发器系统(BTS)之间的指定距离不能超过预定距离。 此外,移动单元与BTS之间的距离变化以及由直接和反射信号之间的相互干扰影响引起的瑞利衰落造成来自移动台的初始上行链路信号的极端信号强度变化。 使用空间多样的天线来接收上行链路信号提供分集增益并减轻深度衰落。 此外,选择较强的空间多样化的上行链路信号可以减轻深度衰落,并减少回程频带中的频率使用。 在这种扩展TDMA系统覆盖的方法中,带内转换器组件位于通常包含基站收发器系统(BTS)的远程小区的中心。 带内转换器包括以预定的前馈方式实现逐时隙选择性空间分集和自动电平控制的延迟元件。 选择性分集减轻了瑞利衰落深度,而动态自动电平控制大大降低了上行链路回程动态范围,从而允许更大的回程距离。 预测前馈自动电平控制还消除了回程高功率放大器的过载和饱和,通常由上行链路功率电平的宽泛变化引起。

    • An apparatus, system, and method are disclosed for sharing referenced content through collaborative business applications. The method includes detecting referenced content in an electronic communication. The referenced content references content stored in an external repository. The referenced content identifies a registered external repository connector. The method also includes determining that an Access Control List (“ACL”) for the referenced content lacks an entry for a recipient of the electronic communication. The method includes generating an ACL entry for the recipient in response to the recipient lacking an entry in the ACL for the referenced content. The ACL entry controls access to the referenced content for the recipient. The ACL entry is defined based on a security policy associated with the recipient.
