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 comma‑separated list of the radio frequency bands that a device can receive or transmit, such as 2.4 GHz, 5 GHz, LTE Band 3, or 5G NR n78. The values are free text and may include band names, numeric frequencies, or both.

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.

A comma‑separated list of the DHCP roles and options a device can provide or use, such as server, client, relay, snooping, option 82 support, IPv6 variants, and other network management functions.

The environmental conditions under which the product is designed to operate safely and reliably, expressed as a temperature range in degrees Celsius and a relative humidity range in percent. Values are typically formatted like "0 °C to 40 °C – 10 % to 90 %" or similar.

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.

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.

A list of the network interfaces and protocols that a device can use for configuration, monitoring and remote management, such as web‑based GUI (HTTP/HTTPS), command‑line interface (CLI) via Telnet or SSH, SNMP, or other standard protocols. Each entry represents one supported method, allowing users to understand how they can access the device remotely.

The largest amount of memory that a device can support, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates the upper limit for active processes and multitasking performance.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

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

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The total number of individual units contained within a single package or bundle. This value helps customers understand how many pieces they receive when purchasing the product, and it is useful for inventory, shipping, and comparison purposes.

A list of the Wi‑Fi standards 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.

The range of relative humidity (expressed as a percentage) within which the storage device is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 - 90 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

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.

The maximum power level at which a device can transmit radio signals, expressed in the appropriate unit such as decibels relative to one milliwatt (dBm) or milliwatts (mW). It indicates the strength of the transmitted signal and is used to assess coverage range and regulatory compliance.

The alternating current voltage range that the product accepts from its power source, expressed in volts (V), together with the acceptable mains frequency range, expressed in hertz (Hz). It indicates the minimum and maximum supply voltages and frequencies compatible with the device.

The radio frequency band(s) that a wireless device supports, expressed as free text such as "Dual-band (2.4 GHz / 5 GHz)", "Single-band (2.4 GHz)", or "Tri‑band (2.4 GHz / 5 GHz / 5 GHz)". It indicates the spectrum(s) on which the device can transmit and receive Wi‑Fi signals.

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.
