微波到毫米波的无线电载波通常用于创建高容量的皮cell无线网络。先进的光纤无线电（RoF）技术可以有效地产生和传输这种载波，并将它们传送到简化的天线站。由于多模光纤在建筑物内网络中占主导地位，因此需要适当的多模光纤无线电传输技术来克服多模光纤链路中的模态色散。介绍了光倍频技术；它实现起来相对简单，但它对模态色散具有鲁棒性，并且能够产生非常纯的微波载流子，同时只需要中速电子器件。因此，它可以在MMF网络的多ghz载波上以综合调制格式传输高数据速率。它提供多种无线电标准的同时操作，以及通过嵌入式控制通道动态适应无线电链路参数（如载波频率、发射功率和其他天线站点功能）的能力。此外，与光路由相结合，它可以动态调整网络配置，以实现灵活的无线服务交付。
Microwave to mm-wave radio carriers are commonly employed for creating high-capacity picocell wireless networks. Advanced radio-over-fiber (RoF) techniques can efficiently generate and transport such carriers, and deliver them to simplified antenna stations. As in in-building networks multimode fiber is predominantly used, adequate radio-over-multimode fiber (RoMMF) techniques are required to overcome the modal dispersion in multimode fiber links. The optical frequency multiplying technique is introduced; it is relatively simple to implement, yet it is shown to be robust against the modal dispersion, and it is able to generate very pure microwave carriers while requiring only moderate speed electronics. Thus, it can convey high data rates in comprehensive modulation formats on multiple-GHz carriers in MMF networks. It offers simultaneous operation at multiple radio standards, and capabilities for dynamic adaptation of the radio link parameters such as carrier frequency, transmit power, and other antenna site functions by means of an embedded control channel. Moreover, in combination with optical routing it enables dynamically adjustable network configurations for flexible wireless service delivery.
