Reduce Network Congestion with Wi-Fi Offloading


For the past few years, 3G/4G networks have become increasingly congested due to the rising penetration of smartphones and tablets. Telecom operators are determined to provide a better communication environment for their customers. As the cost of expanding existing cellular coverage is prohibitive, many operators choose to deploy Wi-Fi, which offers higher throughput and lower RAN costs per gigabit. 4ipnet’s carrier-grade Wi-Fi access layer offloading solution includes Wi-Fi access points, WLAN controller with scalable AP management, and a high performance policy enforcement gateway functionality supporting EAP-SIM authentication. Additional features such as high availability, lawful interception, and specific user routing have also been designed to meet the unique specifications of each operator’s requirements.

Carrier-grade Authentication Methods and Performance

One of the top priorities for carriers today is to monetize their Wi-Fi hotspot deployments while providing smooth and seamless offloading between cellular and Wi-Fi networks. 4ipnet’s solution for carrier Wi-Fi has been proven in large-scale nationwide deployments, supporting login methods such as 802.1X with EAP-SIM, UAM (browser-based login), and WISPr. Additionally, features in 4ipnet’s WHG gateway-controller such as IP address assignment, lawful interception, and specific routing have been designed and optimized to support carrier-grade performance.

Location-based Advertising with Scalable VLANs

Location-based Advertising with Scalable VLANs

Although Wi-Fi networks have yet to demonstrate a competitive average revenue per user compared to traditional cellular technologies, operators have discovered unique methods for Wi-Fi monetization. With 4ipnet, operators can engage in new business models for revenue generation. For example, 4ipnet’s solution supports scalable Q-in-Q VLANs, allowing operators to assign a unique VLAN location ID to each hotspot access point. Combined with customizable captive portals and 4ipnet’s Service Zone concept, operators can enable a location-based advertising platform for business customers nearby the deployed Wi-Fi hotspots.

Virtualization of Network Gateway Functions

4ipnet is collaborating with carriers to migrate existing appliance-based network infrastructure to an NFV (network functions virtualization) architecture. By decoupling traditional 4ipnet gateway network functions such as DHCP server, bandwidth control, and policy routing from dedicated hardware platforms, carriers can increase network scalability, improve rollout efficiency, and enable dynamic resource allocation. Along with system reliability features such as N+1 redundancy and WAN load balancing, carriers can guarantee uninterrupted AAA gateway service with 4ipnet’s solution.
