D-Link DWR-933 Portable Battery-Powered Up to 14 Hours

A list of the cellular network technologies and standards that a device can connect to, such as GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, LTE, VoLTE or 5G NR. The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

A list of the cellular network standards that a device supports for 4G connectivity, such as LTE, LTE‑TDD, LTE‑FDD, LTE‑A, and other variants. The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

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 chemical composition or classification of a battery, such as lithium‑ion, lithium‑polymer, nickel‑metal hydride, sealed lead acid, alkaline, zinc‑air, etc. It indicates the type of electrochemical reaction that stores and delivers energy in the device.

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.

List of the memory card types that a device can read or write, such as MicroSD (TransFlash), SD, MMC, CompactFlash, and others. Each value represents a format that the device’s slot or reader supports for storage expansion.

Indica el tipo o estándar de la conexión Ethernet que posee un producto, como Gigabit Ethernet, 10 GbE, 2.5 GbE, Fast Ethernet, etc. Los valores suelen ser textos descriptivos sin unidades numéricas y pueden incluir varias opciones separadas por comas cuando el dispositivo soporta más de una velocidad.

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 longest period a device can operate on a single charge before needing to be recharged, expressed in standard time units such as hours or minutes.

The largest capacity of a removable memory card that the device can support, expressed as a digital storage size (e.g., megabytes or gigabytes). It indicates the maximum amount of data that can be stored on an inserted card and is useful for comparing devices with different card slot capabilities.

The cellular network generation supported by a device, such as 2G, 3G, 4G, or 5G. It indicates the overall technology tier that determines data speeds and coverage characteristics.

The total count of individual product units that are part of a single purchase or bundle. It indicates how many separate items are available for use, sale, or shipping within the package.

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 electrical potential difference that a device delivers to its load, expressed in volts (V). It indicates the nominal voltage supplied by the product’s power output and is useful for matching it with compatible accessories or systems.

The main electrical supply that powers the device, such as mains electricity (AC), battery, USB power, PoE, or a combination of these options.

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 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.
