IoT wireless connectivity networks are booming to help meet the networking needs of a variety of devices, from connected cars and smart homes to smart lighting and infrastructure. Low-power wide area networks (LPWAN), in particular, are suitable for IoT systems that require low power consumption and ultra-long battery life with carrier-grade security. Several LPWAN technologies, including LTE-M and Narrowband IoT (NB-IoT), are being developed and deployed to support such IoT connectivity needs. LPWAN will have a significant impact on the future growth of IoT innovation.
Выберите правильную сеть IoT
Для создания успешной системы IoT необходимо подобрать подходящую технологию или комбинацию технологий для сетевого взаимодействия. В зависимости от категории приложения IoT предприятиям необходимо учитывать шесть ключевых факторов при выборе технологий сетевого подключения: покрытие, пропускная способность, мобильность, задержка, время автономной работы и стоимость.
Возьмём, к примеру, пропускную способность, которая отражает скорость обмена данными в сети. Что касается парковочных счетчиков в «умных» городах, управление освещением, or other scenarios where less data is exchanged and high latency can be tolerated, data throughput may be a lower priority. However, if the application targets streaming, telemedicine, or involves video scenarios, choosing a high-throughput, low-latency network will be critical.
Преимущества технологии низкого энергопотребления
Снижение затрат и увеличение срока службы батареи всегда были главными приоритетами при разработке архитектуры систем Интернета вещей (IoT). Технологии LTE-M и NB-IoT идеально подходят для решения подобных задач — и не только. В данной статье речь пойдет именно об этих двух технологиях сетевого подключения.
Compared with traditional IoT mobile connection technology, LPWAN technology has obvious advantages. Overall network connectivity costs are expected to be significantly lower than traditional mobile broadband connectivity costs due to wide-area coverage and multi-terminal capacity per region.
Additionally, LTE-M and NB-IoT can provide up to 10 years of battery life for many IoT devices. While 12 to 24 hours of battery life is sufficient for consumer wearable devices, remote asset monitoring devices require much longer. For example, the batteries of smart devices that track assets in the supply chain may last anywhere from seven to more than 30 days at a time, depending on the time and mode of transport, such as land, sea, and air; and the availability of simple switches or containers. Monitoring the capacity of trash cans or liquid storage tanks, the equipment needs to be in the field for many years, and a single battery needs to last for many years as well.
Лицензионный и безлицензионный спектр для LPWAN
Существует две широкие категории технологий LPWAN: лицензионные технологии и технологии, освобожденные от лицензий.
Licensed LPWAN technology leverages mobile network operators’ existing wireless spectrum resources. Mobile operators have long held licenses to operate within dedicated spectrum, used exclusively for wireless communications. This is where they deliver the highly reliable, scalable, and secure network environment that large enterprises have come to expect. Both NB-IoT and LTE-M support licensed spectrum with carrier-grade security.
Технологии LPWAN, не требующие лицензии, могут использоваться в выделенных частотных диапазонах при условии соблюдения правил, связанных с этими диапазонами. Маршрутизаторы Wi-Fi, беспроводные телефоны и другие устройства связи также могут использовать нелицензируемый спектр, что может вызывать помехи в сигнале и снижать производительность сети. Кроме того, технологии, работающие в нелицензируемом спектре, имеют ограниченную зону покрытия, не обеспечивают уровень безопасности операторского класса и не всегда поддерживают двунаправленную связь. Поэтому большинство технологий LPWAN, работающих в нелицензируемом спектре, не поддерживают беспроводное обновление прошивки и программного обеспечения.
Market Status and Future Evolution
With the rapid development of global cellular IoT, NB-IoT and LTE-M have evolved from industry newcomers into the core backbone and mainstream standards of global IoT connectivity. According to GSMA statistics, global licensed LPWAN connections have reached staggering scales in the billions, widely empowering various sectors such as smart cities, промышленная автоматизация, and supply chain logistics.
As complementary low-power IoT technologies, LTE-M and NB-IoT connect directly to mobile networks, eliminating cumbersome Wi-Fi logins or Bluetooth pairing. NB-IoT perfectly handles applications with basic data requirements like smart parking and utility metering, while LTE-M leverages higher bandwidth and mobility to support complex scenarios such as asset tracking, wearable devices, and patient monitoring.
Standing in the present, as 5G and the IoT ecosystem further deeply integrate, investing in and deploying NB-IoT and LTE-M is no longer a matter of “preparing in advance,” but a mature, essential path for enterprises to achieve digital transformation, cost reduction, and efficiency gains. LPWAN continues to accelerate IoT innovation, driving large-scale device deployment and ecosystem prosperity worldwide.
Резюме
The rapid maturation of cellular IoT technologies like NB-IoT and LTE-M has firmly established LPWAN as a vital foundation for modern digital transformation. By balancing low power consumption, carrier-grade security, and flexible spectrum deployment, these technologies empower enterprises to connect massive numbers of distributed devices cost-effectively. As IoT ecosystems continue to expand, leveraging LPWAN solutions unlocks unprecedented operational visibility and drives smarter, more efficient decision-making across industries worldwide.
