Low-power LTE-M accelerates the boom in the Internet of Things

LTE-M is part of the 3GPP LTE standard, with wide coverage, low power consumption, low latency and low cost. It can utilize the existing LTE network infrastructure for low data rate machine-to-machine ( M2M) communication applications provide a cost-effective link network that facilitates the shaping of various IoT applications.

The Long Range Evolution Project (LTE) differs from earlier networks in that its new network core and empty interfacing (OTA) technology provides a groundbreaking combination of efficiency and flexibility.
Efficient use of spectrum reduces costs and provides the ability to combine high-speed, low-latency transmission with cost-effective low bit rate services.

The advanced long-range evolution plan (LTE-Advanced, LTE-A) is superior to conventional LTE because it has a data transmission rate of 300 Mbit/s or higher (through carrier aggregation) and high mobility (car or train). .

Locked M2M application LTE optimized to LTE-M

LTE-MTC (aka LTE-M) is defined as an advanced long-range evolution plan for machine type communication optimization. LTE is claimed to be 4G, but it is technically 3.9G. LTE-A is a true 4G because it meets the requirements of the International Telecommunications Union's fourth-generation wireless system.

The cellular network has transitioned from circuit-switched 2G to packet-switched 3G, 3.5G (HSPDA) and 3.75G (HSPDA+), but 4G represents quantum size. It involves next-generation technologies such as Orthogonal Frequency Division Multiplexing (OFDM) in the null plane, an open interface to a simplified flat all-IP architecture, and Packet Core Evolution (EPC).

OFDM technology avoids selective fading, resists interference, and effectively utilizes the available spectrum, so the 4G LTE network can accommodate up to ten times more traffic than the previous generation. In addition, LTE supports IPv6 and extends the accessible IP space to unlimited.

LTE uses the user equipment category (Category, Cat.) to define performance specifications: the higher the category, the higher the data transfer rate. Cat. 0 downlink rate is 1 Mbit/s; Cat. 1 downlink rate is 10 Mbit/s; Cat. 6 is 300 Mbit/s; Cat. 8 LTE-A data transmission rate will reach 3 Gbit/s. The higher category is determined by the consumer application.

The data transfer rate of 1 Mbit/s is very sufficient for most machine-to-machine (M2M) communication applications. Why should we mention these higher numbers? There are two reasons for this: first, it shows that LTE itself is flexible; second, it shows that research and development work is underway. For example, LTE MTC is part of the upcoming Release 13.

LTE will be a common standard to provide a better user experience

LTE follows a well-defined roadmap with a sustainable upgrade that delivers higher, more stable data rates, higher capabilities and a better overall user experience. It will become a common standard, achieve economies of scale, and have a major impact on personal and business life.

In addition, this is a ubiquitous communication technology that provides the connectivity needs of the upcoming Internet of Things (IoT) era.

LTE is ideal for IoT applications that require immediate response, such as control sensing devices, critical smart grid devices, industrial alarm systems, traffic control systems, and medical devices. The low latency of LTE can accomplish application connections that are not possible in other ways.

The network design feature of LTE is to fall back to the previous generation network when the additional device cannot detect the 4G signal. This is an early, mandatory requirement because different countries have different deployment times and coverage plans.

In addition, falling back is important because it allows equipment manufacturers to validate their solutions in the future.

For companies and industries that recognize that LTE technology will become a global standard and need or sell long-life solutions (such as companies that operate for 10 years or more, such as the automotive industry), it is impossible to rely on 3G forever because 3G is here. It may stop using within the time range.

LTE is the first network technology to meet the most demanding applications (such as instant video surveillance) while providing a cost-effective connection for low-speed applications. Therefore, although these applications have a wide range of performance requirements, the market can build a broad ecosystem on a single, wide-area communication technology. In addition, LTE will strive to create a superior performance, ubiquitous network; scalability; lower cost per bit, providing quality of service and long-term service life to meet customer requirements (mobile network operators are or will stop Use the older generation of network types).

LTE-M improves battery life into the key to IoT connectivity

LTE MTC is part of the global 3GPP standard version 13 that was announced in March 2016. Its advantages include:

. Give full play to the reliability, universality, efficiency and long-term nature of 4G LTE.

. Battery life is increased by means of longer sleep cycles while reducing cost/complexity and increasing coverage that has traditionally been difficult to achieve, such as in buildings and basements.

. Coexist with mobile broadband services to help innovate new machine-to-machine business models.

. The ability to play a key role in the Internet of Things.

So far, many communication module factories have launched various LTE modules. For example, Telit's LTE910/920/930 series, M.2 series data cards, and ATOP 4G platforms can satisfy each. Internet of Things applications. The LE910 is essentially a composite of two high-speed cellular modules; one LTE 3GPP Cat. 3 module provides a downlink rate of 100 Mbit/s and an uplink rate of 50 Mbit/s, and another HSPA+ module provides up to 42 Mbit/ The downlink of s and the uplink rate of 5.76 Mbit/s. If you are unable to register to the LTE network, it will automatically fall back to HSPA+.

The LE910 is available in two different series, one for the North American market and one for the European market. Both include multi-band configurations that cover different series of 4G and 3G bands and certified by mobile network operators. The LE910 also features Multiple Input Multiple Output (MIMO), which is a fundamental feature for data transfer rates and connection reliability.

LTE accelerates vehicle networking/Internet of Things development

The M.2 family of data cards provides LTE high-speed data rates for PC original equipment manufacturers (OEMs). The M.2 specification is ideal for devices with high throughput requirements such as handheld computers, e-readers, tablets and mobile computer processing technology. The M.2 series of data cards enable the mini-card PCI and semi-mini cards to naturally transition to smaller specifications, featuring low power consumption, high-speed USB interface, and support for multiple operating systems.

LN930 M.2 supports the download rate of 150 Mbit/s through the support of 3GPP Release 9. It is available in two versions that support different RF bands and combinations of bands used worldwide. LN930 LTE in North America and Europe joins support for roaming in the Asia Pacific region. The LN930-AP LTE APAC is also available in the Asia Pacific region.

LN932 M.2 achieves a download rate of 300 Mbit/s through the support of 3GPP Release 10 LTE carrier aggregation. It comes in two versions. LN932 M.2 LTE-Advanced supports different RF bands and band combinations used worldwide. LN932 LTE-Advanced in North America and Europe has joined the support for roaming in the Asia Pacific region.

In addition, despite the huge potential of the smart car market, only 8% of the world's cars actually connect to the Internet. But all of the top 14 automakers in the 80% market have a connected car strategy. This means that the automaker's strategy is long-term, and for the programs that are published later, they have embedded the necessary hardware platforms, after which the manufacturer can decide how they must be upgraded or changed.

Unlike early networks, LTE's new network core and air interface technology provides a groundbreaking combination of efficiency and resiliency. Efficient use of spectrum reduces costs and provides the ability to combine high-speed, low-latency transmission with cost-effective low bit rate services.

Multi-regional coverage is the only important issue: empty intermediaries are complex and more than forty different bands are being used in different countries. At the same time as the network is being promoted, equipment and services are also underway, and new functional devices enabled by LTE-A are also in progress. In the next few years, with the standardization and commercial deployment of LTE-MTC, the trend of adopting LTE by IoT OEMs will become more apparent. LTE-MTC provides special features for M2M devices and promises to bring benefits to the IoT market by reducing the cost and complexity of LTE for applications that do not require high performance.
