Cisco 1900 Series Router Hardware information

If you are looking for the small offices or mid level offices where the you need to connect the WAN interlinks there must need to understand the WAN bandwidth requirement from the customer side.

Lets us suppose we have the requirement of 10-20 users in the office, then which router can be used as per the design considerations. Cisco has many different routers in the Cisco 1900 Series router, like they have routers

  • Cisco 1905
  • Cisco 1921
  • Cisco 1941
These 3 routers are generally used for the various bandwidth requirement.

Cisco 1905 : Can be used where requirement is till 10 Mbps of Bandwidth, HWIC card is already inbuilt in this router. It offers a choice of LAN, Serial, 3G, or ISDN modules to accommodate field upgrades to future technologies without requiring replacement of the platform. Cisco 1905 is powered by high-performance multicore processors that support growing demands of branch- office networks by supporting high-throughput WAN requirements.

Cisco 1921 : Can be used where requirement is till 20 Mbps of Bandwidth. Cisco 1921 is powered by high-performance multicore processors that support growing demands of branch-office networks by supporting high-throughput WAN requirements. Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined with an optional Cisco IOS Security license, enables WAN link security and VPN services (both IPsec and SSL acceleration).The traditional console and auxiliary ports are also available. You can use either the USB-based console or the RJ-45-based console port to configure the router

Cisco 1941 : Can be used upto 30 Mbps of the WAN bandwidth, As it can be used for the higher bandwidth as well but as per the standard design recommendations it has to be used till 30 Mbps.Cisco 1941 Series is powered by high-performance multi-core processors that support growing demands of branch office networks by supporting high throughput WAN requirements.Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined with an optional Cisco IOS Security license, enables WAN link security and VPN services (IPSec acceleration).The traditional console and auxiliary ports are also available. Either the USB-based console or the RJ-45-based console port can be used to configure the router.Cisco 1941 supports dual radios - 802.11 b/g/n and 802.11a/n and is capable of operating in both autonomous and unified modes.

So in Cisco 1900 Series, Cisco launches 3 models and can be used as per the requirement of the enterprise or small offices based upon the capacity required in the WAN network.
