聚合射頻在汽車環(huán)境：建筑選擇和天線解決方案

　　使用網(wǎng)關(guān)或集線器連接到Internet服務(wù)提供商（ISP）具有眾所周知的優(yōu)勢(shì)。例如，當(dāng)我們坐在咖啡店，使用Wi-Fi連接時(shí)，我們的設(shè)備使用更少的電力，我們使用更少的分鐘，我們使用更少的數(shù)據(jù)吞吐量從我們的ISP，我們中的許多人支付。此外，我們暴露自己的RF水平是較低水平的信號(hào)，不需要我們的手機(jī)范圍。

　　展望未來(lái)，公共場(chǎng)所、建筑物、餐廳和辦公室將不使用等級(jí)聚合門戶和樞紐的唯一實(shí)體。我們的汽車也會(huì)。大多數(shù)汽車在不久的將來(lái)將提供直接4G，然后5G連接，將作為個(gè)人區(qū)域網(wǎng)絡(luò)的服務(wù)器，我們作為個(gè)人將連接到一次內(nèi)。本文著眼于建筑選擇和天線選項(xiàng)，我們可以使用我們的汽車連接。

　　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.
