MediaTek (MTK) products from Taiwan, China, are widely used by mobile companies and phone design firms in mainland China due to their integration of multiple multimedia features and lower prices. Furthermore, MTK’s completion rate is relatively high, generally above 60%, meaning that mobile manufacturers essentially receive a semi-finished product. With just a little processing, they … Read more
In recent years, IoT technology has gradually become a focal point of attention. With the development of mobile communication technology, many “long-range” IoT technologies have emerged based on traditional “short-range” IoT technologies, bringing a wave of innovation to the industry. Among these emerging IoT technologies, the most frequently discussed are NB-IoT and LoRa. As the … Read more
Hello everyone, I am Xiaozhao Jun. Today, I saw a very shocking diagram in the WeChat group: Those who are in the know should understand. This is the diagram of the entire mobile communication network architecture and protocol specifications by 3GPP. In simpler terms, it is the complete architecture diagram of the core network from … Read more
If you still don’t understand NB-IoT after reading this article, come over and strangle me… 1 1G-2G-3G-4G-5G No explanation, just look at the picture. Where is NB-IoT? 2 NB-IoT Standardization Journey The standardization of 3GPP NB-IoT began in September 2015, and the R13 NB-IoT standard was completed in July 2016. 3 NB-IoT Design Goals and … Read more
1. Introduction Since the concept of “Smart Earth” was proposed, the idea of the Internet of Things (IoT) has rapidly gained global recognition, becoming one of the core driving forces behind a new round of technological revolution and industrial transformation. The IoT is not just about connecting a massive number of objects; it also involves … Read more
Today, the Internet of Things (IoT) industry has entered a phase of rapid large-scale development, with more and more companies in vertical industries engaging in IoT construction. However, there is a divergence in choices between low-rate IoT technologies NB-IoT and LoRa. It seems that LoRa will stand alongside NB-IoT in China, but will that really … Read more
Recently, China Telecom announced the launch of large-scale outdoor testing of NB-IoT in 12 cities across seven provinces, with plans to complete NB-IoT trial commercialization by June. This targets the weaknesses of its two major competitors, creating a rapid and decisive advantage. After all, China Mobile does not yet have an FDD license, and Unicom’s … Read more
With the continuous development of mobile communication technology, the global Internet of Things (IoT) is about to usher in rapid growth. Among international operators, AT&T, Verizon, KDDI, KPN, Orange, NTT DoCoMo, Telefonica, Telstra, and Telus have successively launched commercial eMTC services. In China, China Telecom took the lead, and after establishing the 800MHz networking capability, … Read more
