NB-IoT is a kind of IoT technology with wide coverage, massive connection, lower power consumption and lower cost. For the present, it is still in its infancy. Therefore, the NB-IoT market has become a battleground for the major players.
If you want to find a bright spot at the 2017 China Mobile Partner Conference, then the "139 Cooperation Plan" is definitely not to be ignored. The “1†here, namely China Mobile, will build a mobile Internet of Things with a wide range of technologies and coverage, and achieve continuous coverage of NB-IoT in 346 cities, providing users with convenient and fast Internet of Things service experience.
As a chip maker that promotes the domestic NB-IoT application, MediaTek is pursuing the victory. At the China Mobile Partner Conference, the industry's first dual-mode IoT chip MT2621 supporting NB-IoT R14 specification was released.
"Today at China Mobile's partner conference, the most heard is the 139 cooperation plan. I think this is the layout of NB-loT. China has a good chance to be ahead of the NB-loT and 5G era. The fastest growing place in the world.†The general manager of MediaTek's family entertainment products group, You Renjie, told Ji Wei. The dual-mode NB-loT chip MT2621 released by MediaTek today has low power consumption and cost advantages, and will be in 2018. Mass production was achieved in the first quarter.
The first NB-IoT chip MT2621 supporting R14 dual modeI believe that everyone in the industry knows that Mobike uses the 2G chip of MediaTek to locate the GSM network through GPRS, instead of the NB-IoT chip.
Shared bicycles should be a typical case of NB-IoT applications, but since the NB-IoT definition was in the R13 communication standard, it can only be used for fixed transmission, so it is difficult to use NB-IoT like a shared bicycle. However, the latest R14 standard supports device mobility, and MediaTek is the first to cut into the R14 standard, which will bring more possibilities to NB-IoT applications.
This time, MediaTek released the industry's first dual-mode IoT chip MT2621 supporting NB-IoT R14 specification, supporting NB-IoT and GSM/GPRS network modes, with low power consumption and cost advantages, which can bring rich things. Networked applications such as wearables such as fitness trackers, IoT security devices, smart meters, and various industrial applications.
It can be seen that the MT2621 is an integrated Internet of Things platform that is compatible with existing GSM/GPRS networks in addition to the NB-IoT network. In terms of low power and ubiquitous connectivity for NB-IoT applications, the MT2621 is powered by a power-saving ARM v7 microcontroller (MCU) with built-in flash memory and pseudo-static random access memory (PSRAM) and supports a wide range of audio and video interfaces. The built-in Bluetooth 4.2 communication function is free to connect with other devices nearby.
In terms of product cost and application maturity, the MT2621 uses a simple and cost-effective single SIM card single-antenna design. The terminal device requires only one Universal Integrated Circuit Card (UICC) and mobile number, which can be used in NB-IoT and GSM/ GPRS dual network freely switch, and supports single card dual standby. In addition, the MT2621 integrates a broadband front-end module that supports all ultra-low frequency, low frequency and intermediate frequency bands worldwide, helping terminal equipment manufacturers to push products into the global market faster.
According to the traveler Jie, the MT2621 will be mass-produced in the first quarter of 2018, and the product will be launched in the second quarter of next year. The MT2621's built-in power-saving and connectivity features support the existing GSM/GPRS network and future NB-IoT development, and bring animal networking to the next stage of growth.
On the occasion of China Mobile's "139 Cooperation Plan", MediaTek launched the MT2621 dual-mode IoT chip with NB-IoT R14 specification, mainly considering China Mobile's deployment cycle of NB-IoT continuous coverage in 346 cities. Yu Renjie said that the dual-mode MT2621 chip was introduced because it takes time to consider the layout of the carrier base station. It may take two to three years to estimate the layout time. Of course, in addition to China Mobile, MediaTek is also cooperating with China Telecom. / China Unicom's application requirements in the NB-IoT business.
NB-loT market will grow rapidly in the second half of 2018In fact, in June of this year, MediaTek launched its first NB-IoT chip MT2625, and together with China Mobile to create ultra-small (16mm X18mm) NB-IoT universal module, providing low power consumption for IoT devices. Low-cost solutions are gradually becoming commercially available.
The NB-IoT chip MT2625 supports the latest specifications at the time. The chip is very small, the specification is 5.6mmx5.6mm, which is smaller than the fingernail's nails; its transmission speed will increase by about 4 times; it also supports the R14 standard, suitable for smart home. Static or mobile IoT applications such as logistics tracking and smart meter reading.
It can be seen that MediaTek's NB-IoT chip supports the standard and is the pace of deployment ahead of operators. Yu Renjie said that the reason why the NB-IoT chip supporting R14 is launched so soon is because the existing 2G network application will be replaced by NB-IoT. NB-IoT's transmission speed will be faster, and its low power consumption feature can make the TV life of water meters, electricity meters and other devices on a yearly basis, greatly reducing the cost of battery replacement.
At the same time, on wearable devices, it requires a small chip and saves power, and NB-IoT can meet this demand and support the movement of wearable devices, which is not supported by the NB-IoT R13 standard.
In addition, due to the latest support for the R14 standard chip support device, for some devices with a moving speed of less than 90 km / h, the NB-IoT chip can be installed for tracking. For example, pet tracking, tracking of valuables, logistics tracking, etc., has a wider range of applications.
"Just change 2G to NB-loT, this will be faster, we will choose index customers to support and support in the future." Visitors said that before the MediaTek is pushing mobile phone chip solutions, but NB-loT play It is different from the previous business, because the application is too broad, including the market and the middle layer, we call it the system integrator, which will involve many different special specifications, which are completed by the system integrator, and MediaTek Only the most core chips will be provided.
Overall, the NB-loT market is still in its infancy, and product applications will be dominated by single models. However, with the acceleration of the commercial process in the NB-loT market, single mode is transitioning to dual mode, and dual mode will be the future market trend of NB-loT. And MediaTek can quickly realize the transition to NB-loT chip application based on the advantages of 2G chip application.
"It is expected that the NB-loT market will see relatively rapid growth in the second half of 2018." Visitors said that China Mobile's access port is about 200 million this year, and it is estimated to become 320 million in 2018, an increase of 120 million. Next year, it is possible that the dual mode will account for the majority, and the single mode will develop rapidly. Now the ecological chain of the NB-loT business model is still converging, and it will take some time to increase the formation and maturity of the ecological chain. And MediaTek has already laid the board, waiting for the "wind".
