T-Mobile has rolled out a nationwide narrowband Internet of Things (NB-IoT) service.
Its NB-IoT network covers almost 2.1 million square miles and about 320 million people. The operator claimed to be the first carrier to launch NB-IoT network in the United States. It also claimed that it was first such service to launch worldwide with guard bands.
T-Mobile said that Guard bands are unused areas of the spectrum that insulate one signal from another. It allows T-Mobile gain more efficiency when using spectrum resources and enable IoT applications to avoid interference from other data traffic.
“NB-IoT is a means through which information can be communicated between a sensor and the wireless network utilizing a low-power wide area network [WAN],” David Mayo, Senior Vice President and 5G & IoT Business Chief at T-Mobile.
