Nebula Cloud Networking Access Points ยี่ห้อ ZYXEL รุ่น NAP203
The Zyxel Nebula NAP203 802.11ac Dual-Radio, Dual-optimized Antenna 3×3 Nebula Cloud Managed Access Point is a high-performance 3-stream 802.11ac WiFi AP featuring ultra-fast speeds of up to 1.75 Gbps with a groundbreaking “dual-optimized” antenna design. Through the innovative adjustable antenna setting, the NAP203 can provide the best signal coverage in both ceiling-mount and wall-mount deployments to deliver constant, nocompromise WiFi performance. Additionally, the ultra-slim ID design at 32 mm height blends perfectly into modern interior decorations.
Every Nebula AP has been engineered for cloud management. Based on the NETCONF standard, all data traffi cs between the cloud and APs are exchanged using secure transports to ensure transaction-safe confi guration on all Nebula devices. Furthermore, with the intuitive management interface, administrators are able to control all the APs quickly even without training.
