TP-LINK (DECO E3) Whole-Home Mesh Wi-Fi System with Extender, 2 Pack, Dual Band AC1200

The operating frequency of the alternating current supplied to an AC adapter, expressed in hertz (Hz). It indicates the mains frequency range that the charger can handle and ensures proper operation with the connected device.

The electrical current drawn by an AC adapter when powering a device, expressed in amperes (A). It indicates how much current the adapter supplies to the product during normal operation and helps users verify compatibility with power sources or other equipment.

The range of alternating current voltage that an AC adapter can accept, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the device, ensuring safe operation across different regions and power standards.

The electrical current supplied by an AC power adapter to a device, expressed in amperes (A). It indicates the maximum output current that the adapter can provide under normal operating conditions and helps users verify compatibility with devices or accessories that require a specific input current.

The electrical potential difference supplied by the AC adapter to a device, expressed in volts (V). It indicates the nominal voltage that the charger outputs and is used to match the adapter with compatible equipment.

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.

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 colour or combination of colours that a product’s housing or outer shell is available in, expressed as common names such as "Black", "White" or comma‑separated lists like "Black, White". It indicates the visual appearance of the product’s exterior for consumers.

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 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 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 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 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.

A list of the Wi‑Fi standards that a device supports, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac or 802.11ax. The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

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.
