Cisco Cisco IOS Software Release 12.4(2)XB6

The Cisco BWG functions in the gateway role in WiMax Access Service Network. WiMAX is a 
standards-based wireless technology that offers high throughput broadband connections over long 
distances. WiMAX can be used for a number of applications, including “last mile” broadband 
connections, hotspots and cellular backhaul, fixed and mobile cellular service, and high-speed enterprise 
connectivity for business.

The Cisco BWG colocates both the Decision and Enforcement Points (DP and EP), and acts as an 
interface to the Base-stations in each Access Services Network (ASN). 

The BWG is the key to the IP mobility scheme. It provides the termination of the mobility function 
across base-stations and the foreign agent function. The BWG maps the radio bearer to the IP network. 
It works with the CSN and the policy servers to control policy on behalf of the user. Additionally, it acts 
as an IP gateway for the IP host function that is located on the Base Station. The BWG brings together 
IP functions performed for the access network including end-to-end Quality of Service, Mobility and 
Security.
