On July 9th, Microtek announced that it has partnered with China Mobile to complete the rate enhancement test of NB-IoT R14 standard and become the first chip manufacturer to pass the test. This test uses a development board based on MediaTek MT2625 chip. , R14 measured uplink peak rate up to 150kbps, downlink peak rate reached 102kbps, is 4-6 times the R13 standard rate, indicating that R14 has been in the remote meter reading, over the air firmware upgrade (FOTA), push to talk (Push to Talk or The application capabilities of multiple scenarios, such as Voice over Message, help push the Internet of Things market towards a broader space of development and create more value for the industry chain. With the development of the Internet of Things market and the abundance of business, the R13 standard is up and down. Peak line rate can no longer meet more and more IoT service requirements. In order to ensure that it can achieve the same rate level as GPRS, it can better meet the high requirements for remote upgrade and other data transmission rates and delays of NB-IoT. Power Overlap (LPWA) service scenario, evolving NB-IoT R14 standard increases uplink and downlink peaks by increasing transmission block (2536 bits TBS) and using dual-process (2 HARQ) technology The rate can reach more than 100kbps. At the same time, the NB-IoT R14 standard has also been enhanced in terms of mobility, positioning, multicast and multi-carrier technologies, and further provides better standards and technical support for the development of the Internet of Things market and industry maturity. . Deputy CEO of MediaTek Technologies and General Manager of Smart Device Business Group Zeng Jie said: 'MediaTek is pleased to be the first chip manufacturer to pass the China Mobile NB-IoT R14 interoperability test. MediaTek actively promotes the development of standards for the Internet of Things. Technology R&D plays an important role in the development of the Internet of Things. At present, we have two chips that support R14 – single-mode MT2625 and GSM+NB-IoT dual-mode MT2621. These two chips will be widely used in industry With the consumer Internet of Things (IoT) market, we have accelerated the era of the Internet of Things. 'MediaTek and China Mobile have been working closely together on the Internet of Things. In June last year, they jointly launched the industry's smallest (16mm x 18mm) NB-IoT universal model based on the MT2625 chip. Group, to help manufacturers quickly and easily achieve the development of IoT devices. Afterwards, both parties cooperated in NB-IoT R14 interoperability testing. Internet of things development It is necessary to actively cooperate with the network-side and chip-side vendors to ensure a good experience in the use of IoT devices. The cooperation between China Mobile and MediaTek in NB-IoT is an example. In the future, both parties will cooperate and explore in more areas, and advance together. The win-win development of the Internet of Things industry.
