Figure 1. 3G Wireless WAN HWICs for Cisco Integrated Services Routers
With enhanced data rates and improved latency (below 100 milliseconds), WWAN services are an ideal way to
supplement traditional wireline services. 3G WWAN data services offered today have average data rates well in
excess of ISDN speeds, with theoretical limits in excess of 7 Mbps on the downlink and 5 Mbps on the uplink.
You can use the 3G WWAN as a primary link for sites with lower bandwidth requirements and for mobile
applications. You can also use the 3G WWAN data services as a cost-effective alternative in areas where
broadband services are either not available or very expensive. Cisco is building on these performance milestones
and adding support for wireless to our wide variety of WAN interface alternatives.
