1 LTE Category 0概况机器对机器(M2M)或物联网(IoT)连接是由日渐增多的各种有线和无线技术提供支持的。其中包括蜂窝技术(2G,3G,LTE)、Wi-Fi、个人区域网如蓝牙智能、Zigbee、802.15.4和其他新兴的低功耗广域技术如On-Gamp,SIGFOX,Weightless等等。所有这些技术拥有特定的属性,以支持特定的市场应用。蜂窝技术目前占全球M2M连接总量的15%,将继续拥有较高的收益,并将在很多垂直行业中普遍使用,这些行业的网络运营商能从M2M连接中获得更高的回报。这是因为蜂窝运营商能提供更大的移动性、灵活性和覆盖面、简便的连接管理,以及
1 LTE Category 0 At a Glance M2M or IoT connectivity is supported by a growing variety of wired and wireless technologies. These include cellular technologies (2G, 3G, LTE), Wi-Fi, personal area networks such as Bluetooth Smart, Zigbee, 802.15.4 and other emerging low-power wide area technologies such as On-Gamp, SIGFOX, Weightless and more. All of these technologies have specific attributes to support specific market applications. Cellular technology, currently at 15% of the world’s total M2M connections, will continue to have high revenue and will be widely used in many vertical industries where network operators are able to reap higher M2M connectivity. This is because cellular operators can provide greater mobility, flexibility and coverage, easy connection management, and
