TP-LINK TL-WN881ND Wireless Network Card with PCIe Interface

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 pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render the visual content and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

The spatial pattern of signal transmission or reception for a device, indicating whether it emits or receives signals uniformly in all directions (omni‑directional) or preferentially in a specific direction (directional). This attribute helps users understand antenna coverage and signal propagation characteristics.

Indicates the type of Ethernet flow‑control mechanism supported by a network device, such as IEEE 802.3x or other proprietary variants. The value describes whether and how the device can pause or manage data traffic to prevent congestion.

The operating frequency of a device or component, expressed in hertz (Hz). It represents the number of cycles per second that the product’s internal circuits or wireless radios can run and is useful for comparing performance across similar products.

The amount of signal amplification provided by an antenna or radio component, expressed in decibels relative to an isotropic radiator (dBi). This value indicates how effectively the device concentrates radio energy in a particular direction and is used to compare performance across similar components.

A list of the operational states that an LED indicator on a device can display, such as power status, activity, link, or other functional signals. Each entry represents a distinct status that the LED may show when the device is in use.

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 number of times per second that a display updates its image, expressed in hertz (Hz). It indicates the smoothness and responsiveness of motion on the screen; higher rates generally provide a more fluid visual experience.

A comma‑separated 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 may include both the technical name and a consumer‑friendly label, and they represent all standards that the product claims to support.
