Garderos MPAG supports WiMAX Business Models
Retail WiMAX ISP The Garderos approach is to authenticate users and/or CPE-routers using PPPoE within the WiMAX base station, using the Garderos MPAG, which can be configured to terminate PPPoE sessions. Wholesale WiMAX ISP The MPAG offers a LAC capability1 which can forward the PPP sessions to a centralized LNS. Hotspot WiMAX ISP “Fly-by” users can be authenticated using UAM (Universal Access Method), a portal-based authentication.
Fig. 1: WiMAX scenario
The Garderos MPAG is a decentralized WiMAX access gateway which supports different types of access methods. It can:
- Terminate PPPoE Sessions (BRAS capability) or - Forward the PPP sessions to a centralized LNS (LAC capability1) or - Authenticate and charge “fly-by” users (UAM capability)
