What frequency, bandwidth and rate does NB-Iot use for communication?

NB-IoT uses the 900MHz frequency band to deploy NB-IoT, and some operators deploy it in the 800MHz frequency band. Mainly includes Narrow Band -Internet of Things (Narrow Band - Internet of Things) technology.

NB-IOT focuses on the Low Power Wide Coverage (LPWA) Internet of Things (IoT) market and is an emerging technology that can be widely used around the world. NB-IOT uses License frequency bands and can be deployed in three ways: in-band, guard band or independent carrier, coexisting with existing networks.

In 2016, NB-IoT field-scale networking trials based on 900MHz and 1800MHz were launched in 7 cities (Beijing, Shanghai, Guangzhou, Shenzhen, Fuzhou, Changsha, Yinchuan), and more than 6 business applications demonstration. In 2018, we will begin to comprehensively promote the commercial deployment of NB-IoT across the country.
