Carrier Modifications Make Ultranarrowband Modulation (.PDF Download)

Wireless systems and services occupy bandwidth, which is limited. But not all wireless applications require wide-bandwidth channels. Emerging applications such as sensors for Internet of Things (IoT) functions need just enough bandwidth to move the amount of data generated by the sensor to a communications gateway that is connected to the internet.

For industrial and commercial applications such as these, ultranarrowband (UNB) wireless technology is very attractive as a means of provi
