مشخصات کلیدی Cisco 1921/K9:
توضیح مختصر:
روتر Cisco 1921/K9 یک دستگاه باسیم (Wired Router) است و خودش قابلیت وایفای داخلی یا دوبانده (Dual-Band Wi‑Fi) ندارد.
این مدل طراحی شده برای اتصال از طریق پورتهای اترنت گیگابیت (Gigabit Ethernet) و استفاده از ماژولهای توسعه (EHWIC/HWIC/VWIC) برای قابلیتهای بیشتر، مثل اضافه کردن کارتهای WAN یا Voice.
