Cisco 1921 vs. cisco 1941 vs. cisco 1941 w. More features, more models, more details...

1. Cisco 1900 Routers are designed to meet the application demands of today's small
branches and to evolve to cloud-based services. They replaced /took over Cisco 1800
series becoming the most popular Cisco router today.
Cisco 1900 Series ISR include:
 2 RU and 1 RU units with up to 2 GE integrated WAN ports
 Up to 1 Integrated Service Module (ISM)
 Up to 11 LAN switch ports, two Enhanced High-Speed WAN Interface Card
slots
 Hardware accelerated DES, 3DES and AES for IPSec and SSL VPNs
 Integrated 802.11a/g/n access point with 802.11i, WPA and WPA2 for security
 16 Wireless VLANs and 15 SSIDs
 WAN optimization through WAAS Express
 Secure cloud access with integrated intrusion prevention, content filtering and
cloud web security
What their main features can meet your network needs? Maybe the comparison of
main Cisco 1900 models can help you find out the answer.
