Análisis de los sectores para los que es adecuada LoRa

Introducción a LoRa

LoRa es una solución de IoT de largo alcance y bajo consumo ofrecida por Semtech. Semtech y numerosas empresas líderes del sector, como Cisco, IBM y Microchip, pusieron en marcha la Alianza LoRa (Long Range, Wide Range) y se han comprometido a promover la tecnología LoRaWAN, estándar de la alianza, para satisfacer diversas necesidades de cobertura de área amplia y bajo consumo energético, así como los requisitos de aplicación de los dispositivos M2M. LoRaWAN cuenta actualmente con más de 150 miembros, entre los que se encuentran varias empresas chinas. Se ha implantado comercialmente en varios países europeos y también ha comenzado a utilizarse a nivel nacional.

Análisis de los sectores para los que es adecuada LoRa

From the analysis and evaluation of LoRa technology, LoRa’s advantages are mainly reflected in low power consumption and low cost. When the frequency band interference is small enough, its coverage capability and capacity can also meet the needs of LPWA. Because the technical characteristics are different, one technology cannot fully meet the existing or future low-traffic IoT application needs. At the same time, the maturity stages of various technologies are also different. In the future, multiple technologies may coexist in the market. Comparing LoRa with the current mainstream 3GPP standard technology (the evaluation of 3GPP standards mainly refers to 3GPP related research reports and GSMA research reports), it can be seen that the main characteristics of various technologies are different, and the types of applications they can cover are also different. ,As shown in Figure 4. The shortcomings of LTE-MTC are mainly cost and battery capacity, but it is also sufficient to meet the requirements of wearable applications; while the NB-IoT solution is relatively balanced. The current question that may exist is whether the cost meets the needs of IoT applications. The main shortcomings of the LoRa solution are its support for mobility and the problem of latency, so it is not suitable for real-time applications such as highly mobile applications or industrial system monitoring.

It will take at least 2 years for LTE-MTC and NB-IoT to mature in the industry chain. However, LoRa has already met the commercial conditions for some M2M application characteristics, and LoRa’s price and power consumption have great competitive advantages, so it can be considered for dense distribution in applications. deployed in the area. Before technologies such as LTE-MTC and NB-IoT are commercialized, there will be a time window to transfer some existing M2M services to networks such as LoRa.

Referring to the LPWA business requirements sorted out by GSMA, it is recommended that LoRa businesses choose businesses with smaller data volumes, deep coverage requirements and certain battery requirements, see the table above!
