Indicates whether a device can connect to the Internet using a cellular network such as 3G, 4G, LTE or 5G. A value of "Yes" means the product has the necessary hardware and software to access mobile data; "No" indicates that this capability is not present.

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.

The linear dimension of a pallet measured in a standard unit such as meters, centimeters or inches. It represents the overall length from one end to the other and is used to compare the size of pallets across different products and logistics contexts.

The horizontal measurement of a pallet, expressed in a linear unit such as millimetres or inches. It indicates how wide the pallet is from one side to the other and helps customers assess fit for storage, shipping, or display.

The count of individual units that are packaged together inside a single inner shipping case for transport or sale. It indicates how many separate pieces are included in each case, regardless of product type.

Indicates whether a product is designed to be mounted in a rack system. The value can be "Yes" or "No", or it may specify the height occupied by the device using rack units (U) such as "1U", "2U", or a numeric measurement with unit, e.g., "61.25 mm".

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.

The vertical dimension of the inner case or packaging measured from its lowest to highest point, expressed in a physical unit such as millimetres, centimetres or inches. It applies to any product where the internal dimensions of the shipping or protective case are relevant.

The linear dimension of the inner case or enclosure of a product, measured in a standard unit such as meters, centimeters or inches. It represents the overall length of the internal space available for components or accessories and is useful for comparing sizes across similar items.

The horizontal dimension of a product’s inner case or enclosure, measured in a linear unit such as millimetres or inches. It indicates how wide the interior space is from one side to the other and is used for sizing, fitting, and compatibility purposes with components that must fit inside the case.
