Abstract

Aspects of the subject disclosure may include, for example, a device providing network communications services to user devices using a frequency band and to machine-to-machine (M2M) communication devices in the Internet of Things (IoT). The device monitors traffic loads in the frequency band due to the user devices and due to the M2M communication devices. Depending on the traffic loads, the M2M communication devices use a narrowband carrier within the frequency band, within the adjacent guard band, or separate from the frequency band and guard band as a standalone carrier. The narrowband M2M carriers are dynamically deployed to support the user devices and IoT devices. Other embodiments are disclosed.
