G-4200 SMB Public Access Controller
The Gemtek Systems G-4200 is a high performance and highly integrated Access Controller for public access networks. It combines an IP Router, a 4-port LAN Switch and a complete Access Controller for use in wireless hotspots. One single G-4200 can serve up to 200 simultaneous users, takes control over authentication, accounting and routing to the Internet as well as to the operator' central. Built-in AAA systems make hotspot owners setup public access services without any RADIUS server.

Multiple Authentication Methods and Accounting
The G-4200 supports multiple secure authentication methods from standard web browser login (Universal Access Method), MAC authentication, to 802.1x/EAP with passwords, certificates or SIM cards. The integrated real-time accounting system is based on standard RADIUS/EAP and supports various billing plan from prepaid, pay-per-time, per-volume, per-use or flat rate. Integration into existing OSS/BSS systems can be done with ease.

Built-in AAA with e-Billing and Pre-Paid
Advanced built-in AAA with e-Billing enable private hotspot owner to setup a public access service without any RADIUS Server . Hotspot owner can manage customers with predefined access and billing plans for post-paid subscribers. It also offers an optional account printer for those pre-paid users who can quickly & easily access Internet. Both built-in accounts and Telco roaming accounts are supported simultaneously.

Backend Integration
The G-4200 is compliant to the recommendations of the Wi-Fi Alliance 'Best Current Practices for Wireless Internet Service Provider Roaming' (WISPr). G-4200 has been tested for interoperability with various leading RADIUS and Web application servers (e.g. Funk, AirPath, WiFicom, iPass). For security purposes all AAA and management traffic to the network operation center can be tunneled and encrypted by the internal VPN gateway.

Customizable Login Pages
Service providers can benefit from the flexible web redirection service. G-4200 provides a set of location, browser, and user-specific information to the backend system to enable value added personalized services provided by the WISP. Detailed location information is available via Https/XML interfaces. Web pages can be either stored locally on the G-4200 or remotely on a web portal server.

Zero Configuration for Subscribers
G-4200 makes internet access very easy and user-friendly for the end-user. Subscribers will be redirected to the providers welcome page automatically regardless of their PC configuration. The UAT (Universal Address Translation) feature will accept and translate fixed company IP settings and web proxy configurations - so end-users do not have to reset their corporate IP or web settings.

Remote Management
You can choose a variety of different management interfaces to remotely configure, monitor, or update the G-4200 and the devices behind the controller. The G-4200 can be managed via SNMP, https, SSH or telnet.
