Definition: mobile broadband


Data transmission delivered by cellular carriers to mobile devices. A fundamental component of smartphones, mobile broadband is optional on tablets, laptops and desktop computers. However, it can be easily added with external products (see cellular modem). Speeds are typically less than high-speed fixed broadband subscriptions such as cable and FiOS. However, 4G LTE cellular service competes with DSL, low-speed cable and satellite offerings. See mobile broadband router, cellular data, wireless broadband and cellular generations.
