Qualcomm launched the MDM 9x07 at the beginning of this year, supports Cat 4 up to 150Mbps; the other is MDM 92071, supporting the Cat 1 standard; and last October launched MDM 9206, supporting CatM1, and later through software upgrades to support NB- IoT. Module OEMs are expected to release modules based on MDM 9206 and Cat M1 in early 2017. Support for Cat NB1 is expected to be implemented through software upgrades soon after this.


In addition, in the current Release 13, NB-IoT does not support VoLTE, but in the future Release 14, Qualcomm will try to increase voice support. As NBIoT continues to evolve, Qualcomm hopes to lay the groundwork for IoT standards that are applicable to 5G.


After speaking about the chip manufacturers, the operators are described below.

Since last year, a number of mainstream operators including China, Korea, Europe, the Middle East, and North America have conducted pilots based on pre-standard NB-IoT technology and started end-to-end technical and business verification.


1. China Telecom

China Telecom is actively following up on the development of NB-IoT technology and has officially initiated the research and development of NB-IoT key technologies, terminals and services. In the specific deployment scenario, NB-IoT will be deployed based on the full-coverage 800M LTE network; the base station also supports LTE, NB-IoT and 800MLTE base stations to share baseband, radio frequency, and antenna resources. At the same time, in order to avoid possible frequency interference, and consider the flexibility of the subsequent evolution of the LTE800, priority is given to the independent mode of operation.


In addition, at the "2016 Tianyi Intelligent Terminal Trade Fair" held in July this year, China Telecom united Qualcomm, Huawei, ZTE, Intel, Bosch, SAP, IBM, Ericsson, Shenzhen Venture Capital, Shanghai Institute of Microsystems, Chinese Academy of Sciences, and Beiyou. The 12 units of Southeast University jointly initiated the establishment of “Tianyi Wulian Industry Alliance”.
