On another track of network communication, Narrow Band Internet of Things (NB-IoT) is also attracting attention as 5G. As an emerging technology in the field of Internet of Things, NB-IoT is also known as low-power wide area network (LPWAN), which supports the cellular data connection of low-power devices in the wide-area network, with super coverage, super low power consumption, super low cost, Features such as large connections have prompted NB-IoT technology to be favored by telecom operators and major industry chain companies.
As NB-IoT is included in the 5G standard, it is regarded as the best opportunity to accelerate the implementation of the Internet of Things with its unique advantages, and the industrialization development will also enter a new stage. At present, the number of domestic NB-IoT connected devices has exceeded 100 million, and there have been new advances in technology. NB-IoT will continue to evolve with 5G standards and form synergy with other 5G standards to ensure that the terminals of industry chain enterprises can meet the continuous changes in the market and be compatible with previous-generation products.
Recently, MediaTek and China Mobile jointly conducted a multi-carrier enhancement pilot verification of the NB-IoT R14 standard under the existing Beijing network, and took the lead in completing the large-capacity test of concurrent FOTA services for 100 terminals under three carriers, further verifying the higher transmission rate and higher transmission rate. Low-latency business satisfaction. With the large-scale deployment of NB-IoT, multi-carrier enhancement technology will improve cell capacity and throughput performance. Combined with China Mobile's entire network that has enabled NB-IoT R14 rate enhancement and power optimization RAI functions, it will better support large Concurrent capacity application scenarios promote the broader market development prospects of NB-IoT.
This joint test is based on the MediaTek MT2625 commercial module. In this test environment, a 300KB download of the FOTA file is taken as an example. In an excellent point, the three-carrier can achieve 100 terminals to complete the service in an average of 8 minutes (under the same conditions, single carrier) Able to achieve about 30 terminal services). The NB-IoT three-carrier cell reaches approximately 3.3 times the service capacity of a single-carrier cell, which can effectively support the subsequent large concurrent services of the narrowband mobile Internet of Things.
In the NB-IoT market, many manufacturers have also handed in a good report card, which has played a role in promoting the popularization of NB-IoT technology. For example, Tuya Smart has developed three NB-IoT modules, NM1, NM1-CT and NM1-GL based on MediaTek's MT2625 NB-IoT chip, and based on the modules developed outdoor intelligence including street light controllers, fire hydrant detection and municipal manhole covers. The equipment can realize real-time remote control of street lights and detect the status of outdoor intelligent equipment such as fire hydrants and manhole covers.
GosuncnWelink also developed the ME3616 module based on the MediaTek MT2625 NB-IoT chip, which has a small size, full frequency band, full certification, high reliability, wide voltage and other performance. It is extremely competitive in the industry and has achieved large-scale commercial use in industries such as smart gas meters, smart water meters, security monitoring, asset tracking, and wearables.
NB-IoT is bound to open a new chapter for the Internet of Things. MediaTek's NB-IoT chip has high integration and dual-mode advantages, and has a complete IoT software and hardware development platform, which can be applied to various NB-IoT terminals. MediaTek and China Mobile have worked closely in the NB-IoT field. They have launched NB-IoT universal modules, one-stop solutions, and completed R14 rate enhancement tests, which not only brings innovation and opportunities to vertical industries, but also jointly promotes the IoT industry Accelerated development.
