Deployment / Use Cases
This wireless adapter is designed for desktop computers in environments where running Ethernet cables is impractical or where wireless connectivity is preferred. It's particularly useful for office workstations, point-of-sale systems, and home desktop setups that need reliable Wi-Fi access.
The card suits small businesses upgrading older desktops, IT departments deploying standardized wireless connectivity across multiple workstations, and home users adding Wi-Fi to custom-built PCs. Its TAA compliance makes it appropriate for government and educational procurement where sourcing requirements apply.
Office Workstation Upgrade
Add wireless connectivity to existing desktop computers without replacing entire systems, maintaining productivity during office reconfigurations or expansions.
Small Form Factor Solutions
The low-profile bracket enables installation in compact desktop cases commonly used in retail, healthcare, and space-constrained environments.
Physical Profile
Measuring 1.90" wide by 0.70" high by 3" deep (48.26 x 17.78 x 76.20 mm), the adapter has a compact footprint that fits standard PCIe slots. The lightweight design at 1.30 ounces (36.85 grams) minimizes strain on the motherboard slot while the detachable antennas allow flexible positioning for optimal signal reception.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 0.70" (17.78 mm), 1.90" (48.26 mm), 3" (76.20 mm), 1.30 oz (36.85 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
