/etc/nginx/nginx.conf.华为海思原来这么厉害，跪了
电子发烧友
高通可谓是这个领域的专家（买基带送CPU的的美名可不是浪得的）然而华为也一直在做巴龙基带芯片，而且还是相当成功的，以前主要用于数据卡上。终于在2014年，华为把巴龙和K3合在一起，开始做SOC，就是把多个功能集成到一个芯片上去，K3甚至只能叫做AP而不能叫SOC，这才有了K910和K920的问世。华为真正核心价值力的，是海思基带芯片Hi6920， 要能支持2/3/4G，要把3gpp协议读透，然后结合写软件，结合硬件DSP，这真是不坐几年冷板凳做不出来的。在去年，华为更是推出巴龙750基带，有媒体甚至喊出了碾压高通这样的口号。Balong 750在全球范围内第一个支持了LTE Cat.12、Cat.13 UL网络标准，理论下载速率高达600Mbps，而上传也达到了150Mbps。相比之下，高通最新的MDM9x45也仅支持到Cat.10，下载450Mbps、上传100Mbps，而联发科预计年底才会有Cat.10基带。事实上，LTE Cat.12的下行速度就已经提升到600Mbps，不过上行只有100Mbps，而华为没有满足于此，Balong 750突破达到了150Mbps，从而符合LTE Cat.13 UL上行标准。据华为介绍，Balong 750能够根据运营商的频谱资源和网络覆盖，通过2CC（双载波）数据聚合、4x4 MIMO多入多出技术（一个无线信道中堆叠4个空间流），或者4CCA（四载波聚合）技术，提供高达600Mbps的下载速度。一般来说，运营商都会有至少两个频段区间，但每个频段带宽资源有限。频谱较少的运营商，需要通过载波聚合技术，提升LTE网络容量，达到更高的下载速度；即使是频谱较多的运营商，也需要通过载波聚合技术，提升网络覆盖，实现真正的网络无缝联接。针对频谱资源较少的运营商，Balong 750会采用2CC＋4x4 MIMO技术，使下行速度达到600Mbps；针对频谱资源较多的运营商，则会采用4CCA技术，扩大网络的覆盖范围和带宽能力。Balong 750也是目前唯一一款支持4CCA的基带芯片。华为海思作为国内半导体领域一个代表厂商，是毋庸置疑的，展望未来，海思能够给我们带来什么惊喜呢？让我们翘首以待。
