    • A radio-over-fiber (RoF) wireless picocellular system adapted to form an array of substantially non-overlapping individual picocells by operating adjacent picocells at different frequencies is operated to form one or more combined picocells. The combined picocells are formed from two or more neighboring picocells by the central head-end station operating neighboring picocells at a common frequency. Communication between the central head-end station and a client device residing within a combined picocell is enhanced by the availability of two or more transponder antenna systems. Thus, enhanced communication techniques such as antenna diversity, phased-array antenna networks and multiple-input/multiple-output (MIMO) methods can be implemented to provide the system with enhanced performance capability. These techniques are preferably implemented at the central head-end station to avoid having to make substantial changes to the wireless picocellular system infrastructure.
    • 适用于通过以不同频率操作相邻微微小区来形成基本上不重叠的单个微微小区的阵列的无线电光纤(RoF)无线微微蜂窝系统被操作以形成一个或多个组合的微微小区。 组合的微微小区由两个或更多个相邻微微小区由中央头端站以相同的频率操作相邻微微小区来形成。 通过两个或更多个应答器天线系统的可用性,中央前端站和驻留在组合微微小区中的客户端设备之间的通信得到增强。 因此,可以实现增强的通信技术,例如天线分集,相控阵天线网络和多输入/多输出(MIMO)方法,以向系统提供增强的性能能力。 这些技术优选地在中央头端站处实现,以避免必须对无线微微蜂窝系统基础设施进行实质性改变。
