Cisco 802.11ac Wave 2 4×4 Antenna Extender AP

The radio frequency band used by a wireless device, expressed in gigahertz (GHz). Common values include 2.4 GHz and 5 GHz, which indicate the operating spectrum for Wi‑Fi or other wireless protocols.

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

The highest directional signal amplification a device’s antenna can provide, expressed in decibels relative to an isotropic radiator (dBi). It indicates the maximum gain achievable by the antenna and helps users compare coverage or range potential across devices.

The total count of independent communication or signal pathways that a product can provide or receive, such as audio channels, video streams, data links, or radio frequencies. It indicates how many separate signals can be transmitted or processed simultaneously and is expressed as an integer.

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 positions or mounting options where a product can be installed, such as indoor, outdoor, wall, desk, floor, ceiling, or universal. Each value represents a distinct placement scenario that the device supports.

The type of network interface used to connect a device to the wide‑area network (WAN). It specifies the physical connector and protocol, such as Ethernet (RJ‑45), ADSL (RJ‑11), or mobile cellular (SIM/USB). This attribute helps users identify the required cables, adapters, or SIM cards for external connectivity.
