Is there a solution for the smart Internet of Things at the recent 218 Mobile World Congress?

at this MWC Shanghai conference, narrowband internet of things (NB-IoT) technology shines brilliantly, and new NB-IoT chips, software, network platforms and product forms appear one by one, which fully embodies the technical advantages of cellular internet of things, such as full connection, wide coverage, strong link, low cost, low power consumption and easy management. The RG-NB6118 IoT communication module independently developed by Ruijie Network is quite impressive.
