The correct answer is A. Multimedia processing.
DECT (Digital Enhanced Cordless Telecommunications) is a family of digital radio standards for cordless telephony. It is designed to provide high-quality voice and data communications in a variety of environments, including homes, offices, and public spaces.
DECT is used in a variety of applications, including:
- Cordless private branch exchange (PBX): A PBX is a telephone system that allows users to make and receive calls within a private network. DECT can be used to provide cordless extensions to a PBX, allowing users to move around freely while still being able to make and receive calls.
- Wireless local loop (WLL): WLL is a type of fixed wireless access that uses radio waves to provide telephone and data services to homes and businesses. DECT is often used for WLL networks because it offers good voice quality and coverage.
- Home cordless phones: DECT is the most common type of cordless phone in use today. It offers good voice quality and range, and it is relatively inexpensive.
Multimedia processing is not an application of DECT. Multimedia processing is the process of manipulating and storing digital multimedia data, such as audio, video, and images. DECT is not designed for multimedia processing, and it does not offer the features and capabilities that are required for this type of application.
