一家名为 Hubble Network 的初创团队拿到了包括美国YC投资等机构在内2000万美元的A轮融资,其主营业务是打造“蓝牙卫星网络”,让蓝牙设备通过卫星联网,为蓝牙行业提供新的物联网定位和追踪方案。这家公司称其业务为“物联网设备的星链”(Starlink for IoT devices),意图通过卫星群,为全球所有装有BLE芯片的设备提供实时的数据更新。 Hubble Network的蓝牙卫星网络 ,其核心科技是一个简单的固件(software framework),它可以使目前全球所有装有BLE芯片的传感器或设备直接接入该公司的卫星网络,并自动提取设备的数据,不需要额外的硬件改变,像是专有的调制解调器或定制芯片组。 也就是说,蓝牙用户不需要额外添加任何的硬件,只靠对软件架构的调整就能实现真正意义上的全球连接。对此,Hubble Network的CEO,Alex Haro表示,公司通过降低比特率和每秒传输的数据量等方式,已经能够使蓝牙设备实现全球范围的连接。此次融资,也让Hubble Network能够在明年1月使用SpaceX发射第一批的四颗卫星,并在之后激活早期试点客户。  除了固件这个核心科技以外,Hubble Network还重新进行了卫星天线的设计。该公司即将发射的卫星,不仅只有一根天线在卫星总线上,而是在每颗卫星上都使用数百根天线,这让蓝牙卫星可以支持数百万个地面的蓝牙设备连接。对此,Alex解释说,“这几乎是一个在地球表层的巨型放大镜,它能够探测到这些从蓝牙芯片出来的非常微弱的无线电信号,使你能够实际破译和接收蓝牙信号。”  简而言之,这个“蓝牙天网”,相当于在空中发射几个基站,使全球蓝牙设备能够与基站连接,为蓝牙设备的数据传输添加了一条新的路径,也为蓝牙BLE增加了新的功能和应用场景。...
