Intel, Qualcomm and Sequans launched low-power, low-data rates such as LTE Cat. M and narrow-band Internet of Things (NB-IoT) at this year's Global Mobile Communications Conference (MWC) The chip solution, for the development of IoT machine-to-machine (M2M) communication applications, is focusing on new growth momentum.
The development of the Internet of Things technology writes a new page. This year's communications industry's annual event - Global Mobile Communications Conference (MWC), the Internet of Things and 5G can be said to be the two most popular focus of the venue, whether it is the product display at the booth, or the manufacturer's press release around this Two topics.
Different from the high transmission rate applications discussed earlier, the biggest progress in the development of the Internet of Things is the emergence of various low-power, low-data-rate technologies and chip solutions, especially the long-range evolution plan (LTE). In this development, this will help machine-to-machine (M2M) communication applications to flourish, thus accelerating the advent of the era of universal interconnection.
Low data rate chips compete for M2M applications
In fact, LTE has started from the 12th edition (Release 12) standard, that is, the development of high-speed and low data rate parallel lines. On the one hand, it continues to advance to high-speed specifications such as Cat. 10/11/12 to meet the high-frequency width. The application requirements of high data throughput, on the other hand, are also actively developing LTE machine type communication (MTC) related standards, in order to balance the demand for low data rate and low-cost networking technologies of the Internet of Things, and expand the LTE power map to the object. Networking for various application areas.
Compared with the LTE and LTE-A high-speed mobile networks, LTE's MTC communication protocol architecture is quite streamlined, tailored for IoT M2M applications, enabling device-to-device communication at lower cost and mitigating telecom core networks. The amount of data is burdened. Following Cat. 1/0, 3GPP proposed the Cat. M specification in the 13th edition of the LTE standard to further reduce the transmission rate, allowing LTE technology to accelerate the field of M2M sensing, communication, computing and instant control applications.
This year's MWC, including Intel, Qualcomm and Sequans, has consistently released low-power, low-data-rate chips that support the LTE Cat. M standard and the latest narrow-band Internet of Things (NB-IoT). It is expected to inject strong momentum into the development of LTE in the field of application of IoT M2M.
Take Intel as an example, its XMM 7115 modem chip is designed for NB-IoT devices and applications. Another XMM 7315 modem chip integrates LTE modems and application processors into a single chip, supporting LTE Cat. M and NB-IoT standards, suitable for large-scale coverage, low power consumption, and Low-cost Endpoint products.
Sikuo is working with RF chip developer Skyworks to create the best solution for LTE Cat. M applications to meet the growing demand for embedded cellular connectivity technology in the Internet of Things. This device leverages the Skyworks half-duplex RF front-end module and the new Monarch LTE Cat. M single-chip, which simplifies the original equipment manufacturing for the integrated turn-key solution that complies with the 3GPP R13 LTE standard. The OEM (OEM) development process accelerates the time-to-market of low-data-rate, low-power LTE devices and meets the needs of global network operators.
On the other hand, Qualcomm demonstrated two low-power LTE applications at the MWC venue; one of them was to show how the LTE IoT device uses the power-saving mode (PSM) of the MDM9207-1 modem, reaching 10 with two 3rd batteries. The battery life of the year, and the second demonstration is the finished product developed in cooperation with Ericsson, showing the Extended Idle DRX function published in the 3GPP Release 13 specification. The LTE Extended Idle DRX synchronizes the timing of the mobile network and the IoT device. At very long time intervals, the device can be woken up at a timely time and receive data from the network, thus extending its battery life.
Although MediaTek has not launched LTE Cat. M or NB-IoT related solutions, it is also optimistic about the demand for low-data-rate and low-power data-computer chips for IoT M2M applications, and jointly exhibited with Nokia to reduce power consumption and enhance The network-covered EC-EGPRS solution meets the frequent data transmission needs of billions of IoT devices and sensors in the future. This EC-EGPRS solution demonstration is based on MediaTek's data machine chip technology and protocol software, as well as Nokia Flexi MulTIradio 10 base station and mobile base station supporting EC-EGPRS.
Telecom equipment vendors add code to invest in IoT M2M applications
In addition to the chip vendors' low-data-rate, low-power M2M application market, telecom equipment operators have begun to expand the relevant layout.
eMTC communication takes the big step Nokia/KT for field test
In response to the demand for machine-to-machine applications and communications that are rapidly increasing in the Internet of Things, Nokia Communications has teamed up with Korea Telecom to showcase the world's first eMTC (enhanced Machine Type CommunicaTIons) field test.
It utilizes the wireless technology of Nokia Communications to exploit the potential of eMTC, coexist with existing LTE networks, expand its coverage, and achieve medium data transmission rates, laying an important milestone for the development of the Internet of Things.
Nokia Communications Korea leader Andrew Cope said that there were nearly 50 billion connected devices in 2025. In order to continue the growing Internet of Things, the company successfully demonstrated the potential of LTE as the backbone of the Internet of Things through this field test.
According to Chang Seok Seo, senior vice president and network strategy leader of Korea Telecom, the field test provides a reliable platform to drive a wide range of service applications by addressing the barriers to the development of the Internet of Things. Together with Nokia, Korean Telecom can play an important role in creating an Internet of Things in Korea.
Korea Telecom and Nokia have conducted the industry's first eMTC field test, which is intended to drive the connected world through telecom communication technology. This field test was conducted on Korea Telecom's LTE network (this network utilizes the Nokia Flexi MulTIradio 10 base station). The eMTC uses only 1.4 MHz of the 20 MHz LTE system, allowing the rest of the spectrum to perform normal LTE communication.
It is understood that the 3GPP R13 version will move from LTE-A to LTE-A Pro. eMTC is a feature of this version, which is considered to be LTE-M running at 1.4MHz bandwidth. Compared with traditional LTE, eMTC can provide data rates up to 1 Mbit/s, and better quadruple coverage, while reducing device complexity by up to 80%, and enabling more data-rich sensors with low cost. Networking, such as environmental monitoring or building monitoring of LTE networks in rural areas.
