Green Packet's SONaccess system presents an integrated solution for secure seamless roaming between different WLAN networks, and between WLAN and wide-area 2.5G/3G networks like GPRS or CDMA 1x.

SONaccess supports major WLAN aggregators like iPass and GRIC to tie up the networks to create an even bigger footprint for hotspot operators to drive market acceptance and increase revenues.

SONaccess seamless handoff allows network providers to centrally manage user access while supporting multiple authentication schemes including Web and SIM-based authentication widely used by cellular operators.

SONaccess enables easier transition from desktop to mobile broadband and with suitable applications, creates shared data traffic for the operator's extended network.

SONaccess supports both RADIUS and DIAMETER AAA and interoperates with major VPN solutions for secure network access. SONaccess comes in two hardware variants for the enterprise and carrier markets.
