Active Devices

Any electrically powered device that boosts signals via amplification or filtering.

All-Band Calibration

E2E calibration enables high-precision beamforming by accurately tuning phases for network links. In 5G, beamforming is a basic capability for all bands, making all-band calibration a fundamental requirement.

Analog Return

The upstream return path to the headend or hub using analog optical fiber nodes.

API: Application Programming Interface

In general terms, an API is a set of clearly defined methods of communication between various software components; a set of subroutine definitions, protocols, and tools for building application software.

Beamforming

Beamforming is a key wireless technique that utilizes advanced antenna technologies on both mobile devices and networks’ base stations to focus a wireless signal in a specific direction, rather than broadcasting to a wide area.
