T-Mobile Rolls Out Narrowband IoT Communications Nationwide
As part of its run-up to nationwide 5G communications, T-Mobile has launched narrowband IoT, a series of bands intended specifically for sensors and other devices that communicate only small amounts of data at any one time, but which need a dedicated band in which to do it. To do this, T-Mobile has utilized the guard bands, which are narrow slices of frequencies next to their LTE bands used for cellular communications, as a way to achieve spectrum efficiency.
Narrowband IoT is designed to provide a pathway for low-power devices that don’t require much bandwidth to communicate without interference.
