Admin ơi, mình có thể sử dụng Cisco Catalyst 9115AXI-S cho các ứng dụng ngoài trời không?
Chào anh, Cisco Catalyst 9115AXI-S chỉ dành cho trong nhà, không chịu được thời tiết ngoài trời.
Cisco Catalyst C9115AXI-S có hiệu quả về chi phí so với các sản phẩm cùng loại không ạ?
Cisco Catalyst C9115AXI-S hiệu quả về chi phí nhờ giá hợp lý, hiệu năng Wi-Fi 6 mạnh mẽ, tích hợp Bluetooth 5.0, và dễ triển khai quản lý.
Nếu đặt 2 thiết bị C9115AXI-S quá gần nhau (dưới 5m), có cần tắt tính năng nào không để tránh interference không vậy shop?
Nếu đặt hai thiết bị C9115AXI-S quá gần nhau (dưới 5m), bạn nên: Giảm công suất phát sóng, chọn kênh khác nhau cho từng thiết bị, giảm độ rộng kênh xuống 20/40MHz, tạm tắt một băng tần nếu không cần thiết. Không cần tắt tính năng MU-MIMO hay OFDMA trừ khi gặp vấn đề thực tế.
