　　聚合射频在汽车环境：建筑选择和天线解决方案

　　使用网关或集线器连接到Internet服务提供商（ISP）具有众所周知的优势。例如，当我们坐在咖啡店，使用Wi-Fi连接时，我们的设备使用更少的电力，我们使用更少的分钟，我们使用更少的数据吞吐量从我们的ISP，我们中的许多人支付。此外，我们暴露自己的RF水平是较低水平的信号，不需要我们的手机范围。

　　展望未来，公共场所、建筑物、餐厅和办公室将不使用等级聚合门户和枢纽的唯一实体。我们的汽车也会。大多数汽车在不久的将来将提供直接4G，然后5G连接，将作为个人区域网络的服务器，我们作为个人将连接到一次内。本文着眼于建筑选择和天线选项，我们可以使用我们的汽车连接。

　　Moving targets

　　Robust protocols with ECC are highly desired for any transceiver that will be used in an automotive hub or aggregator. Not only do distance， line of site and environmental conditions affect performance， movement can make reception more prone to errors and hits. By moving， different signal strengths and distortions due to multipath reflections can and do cause errors.

　　While conventional thinking will say to use the least amount of hardware and keep costs as low as possible， sometimes redundancy， partitioning， and extra cost is needed to make the system usable and function reliably. Even at low-data rates like voice， hits that are not error-corrected do suffer from performance degradation. We all have experience with cellular voice signals that are cutting in and out and not delivering data reliably.
