To Wi-Fi users, it is not uncommon to have bad experience on Wi-Fi performance, and antenna design plays an important role while evaluating wireless performance. Today, most access points on the market are designed with single static radiation pattern, typically for ceiling-mount. When an AP with ceiling-mount pattern is installed in wall-mount scenario, its signal coverage does not fit for wall-mount deployment. Adapting an AP with external antenna may be the alternative option, however, external antenna installation requires know-how for antenna selection, and would look awkward for interior decoration. A flexibly installed Wi-Fi AP with optimal performance and stylish outlook is a prerequisite today, but a satisfactory solution has been missing for a long time. ZyXEL's WAC6103D-I is a high performance 3-stream 802.11ac Wi-Fi AP featuring ultra-fast speeds of up to 1.75 Gbps with ground-breaking 'dual optimized' antenna design. Via the innovative adjustable antenna setting, the WAC6103D-I provides the best signal coverage fitting for either ceiling-mount or wall-mount deployments. Even better, the stylish, ultra-slim industrial design perfectly blends into modern decorations. Choose WAC6103D-I for constant, no-compromise Wi-Fi performance. Ceiling-mount installation is the most common type of wireless deployments, and it is not surprising that most APs on the market are designed with single static radiation pattern for ceiling-mount installations. In wall-mount scenarios, the ceiling-mount radiation pattern would create interference with devices on upper and lower floors, meanwhile it delivers short-range signal for wireless clients at the AP front. Choosing an AP with external antenna may be the alternative option for wall-mount installation. However, the installation usually requires professional knowledge for antenna accessory selection and signal coverage fine-tune. Designed with the innovative 'Dual-optimized' antenna.
