The classification of an antenna used in a device, indicating its physical configuration or mounting style such as external, internal, integrated, directional, omnidirectional, or multi‑antenna setups (e.g., "2x2", "4 x External"). It helps buyers understand how the antenna is attached and what signal coverage it may provide.

The total count of antenna units present on a device or system. It indicates how many separate antennas are installed and can help assess potential signal coverage and performance.

A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

List of operating systems that the product can run or support, including specific versions and architectures when relevant. Each value represents a distinct OS that is compatible with the hardware or software.

The network and data interface technologies supported by the product, such as Wired, Wireless, USB, Bluetooth, or combinations thereof. Each value represents a distinct technology that can be used for communication or power delivery.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

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 vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

List of physical or logical interfaces that allow communication between a host device and other components, such as USB, PCI Express, SATA, M.2, Ethernet, Thunderbolt, or similar standards.

List of physical or logical interfaces that allow communication between a hard drive and other devices, such as SATA, M.2 PCIe, U.2, SAS, NVMe, or other standard connections.

Indicates whether the product is designed to be installed inside a computer system or other device, such as an internal hard drive, SSD, network card, or component. A value of "Yes" means it can be mounted within the chassis; a value of "No" indicates it is intended for external use.

A list of the functions or statuses that an LED indicator on a device can display, such as power status, activity, link, and other operational signals.

The highest theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.

The modulation technique used by a wireless device or component to encode digital information onto a carrier signal. Common schemes include QAM, OFDM, PSK, FSK and their variants. This attribute helps users understand the signal processing method and compatibility with other equipment.

A list of the networking protocols and standards that a device can support or comply with, such as IEEE 802.11 variants for wireless, IEEE 802.3 for Ethernet, or other relevant networking specifications. The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

Indicates whether the product is manufactured in accordance with the RoHS (Restriction of Hazardous Substances) directive, which limits the use of certain hazardous materials in electrical and electronic equipment.

Una lista de los algoritmos criptográficos y protocolos de seguridad que el producto soporta, como cifrado (AES, WEP), autenticación (WPA2-PSK, EAP-TLS) o protocolos de red (HTTPS, SSH). Cada elemento describe un algoritmo individual; la lista puede contener varios valores separados por comas.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.

Indicates whether the product has built‑in Wi‑Fi capability, allowing it to connect to wireless networks without requiring external adapters or dongles.

A textual description of the Wi‑Fi frequency bands supported by a device, such as "Dual-band (2.4 GHz / 5 GHz)" or "Tri‑band (2.4 GHz / 5 GHz / 5 GHz)". The value indicates which radio frequencies are available for wireless communication and helps users understand the device’s connectivity capabilities.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as 802.11a, 802.11b, 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.

Indicates whether a product has wireless connectivity and, if so, which wireless technologies it supports (e.g., Wi‑Fi, Bluetooth, RF). The value can be "Yes" or "No", or a textual description of the supported protocols.
