Yealink W90B DECT Base Station White

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Indicates whether the product includes an Ethernet LAN interface for wired network connectivity, allowing data transmission over RJ‑45 or compatible cables.

Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.

The span of frequencies, expressed in hertz (Hz), that a device can operate within or respond to. It may be given as a single value, a numeric range (e.g., "20 000‑50 000 Hz"), or an open‑ended interval such as "2.4 GHz+" indicating the lower bound only.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The range of electrical voltage that a device can safely accept from its power source, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the product, covering both AC and DC inputs where applicable.

The greatest distance over which the product can effectively operate or communicate, expressed in metres.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

A list of network communication protocols that a device can use or support, such as TCP/IP, HTTP, HTTPS, FTP, DHCP, DNS, and various wireless standards. Each protocol is represented by its standard name and may be separated by commas or slashes in the source data.

A list of audio codecs that the product can use for transmitting or recording voice signals, such as G.711, AMR‑NB, Opus, etc. Each value represents a valid codec supported by the device’s hardware or software.
