User’s Guide Chapter 1 – Introduction
Chapter 1 – Introduction
Thank you for choosing the Gemtek Systems 54 Mb High Performance Hotspot-in-a-Box.
The Gemtek Systems P-560 is a high performance and highly integrated Access Controller for public
access networks. It combines a high-speed wireless LAN Access Point, an IP Router, a 4-port LAN
Switch and a complete Access Controller for Wi-Fi Hotspots in one box. One single P-560 can serve
up to 100 simultaneous users (depending on SW license), takes control over authentication,
accounting and routing to the Internet as well as to the operator’s central.
Product Overview
Scalable With Customer Needs
The P-560 Access Controller can be ordered with three different software licenses allowing operators
to extend functionality as their business grows. The basic “Bronze” license already supports all
required functions to operate a public access network for up to 20 simultaneous subscribers. The
“Silver” license is an upgrade for unlimited users (up to 100) and multiple WISP support whereas the
“Gold” software enables wireless LAN switching and remote AP management to the network.
Authentication, Authorization & Accounting
The P-560 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 plans from prepaid, pay-per-time, per-volume, per-use or flat rate. Integration into
existing OSS/BSS systems can be done with ease.
Service Differentiation
The integrated Web server of the P-560 allows flexible interaction with common web application
servers, facilitating the provisioning of differentiated services with bandwidth management, location
based and personalized services. Inter-Provider roaming and multi-OSS support is guaranteed by the
persistent usage of standardized protocols and interfaces like RADIUS, HTTPS and XML. As all
Gemtek Systems Access Controllers P-560 is compliant with the recommendations of the Wi-Fi
Alliance WISP roaming group.
Remote Control
The P-560 Hotspot-in-a-Box is placed at the edge of a broadband access network and allows
operators to provide cost effective public Wi-Fi services, by managing per user access control, device
configuration, and radio performance centrally from the operations centre. HTTPs, telnet, SSH or
SNMP over VPN can be used for secure remote management.
Privacy
P-560 supports different levels of security and data encryption. Client stations can be separated on
link layer (Layer2 User Isolation), preventing intruders from accessing the hard discs of other users.
User credentials (passwords) are protected by SSL or EAP-based authentication methods. User traffic
can be encrypted either by VPNs (pass-through) by Wi-Fi Protected Access (WPA). Operators and
service providers can make use of the integrated VPN/tunneling protocols to protect AAA and
management traffic.

User’s Guide Installation
Step by Step Setup
Step 1. Interface Set-Up
In the network interface | configuration menu you can set the TCP/IP settings. Eth0 is pre-
configured as the WLAN port of your Access Controller, Ixp1 is the WAN port, and Ixp0 is the LAN
port. You can modify these settings according to your local network requirements. Make sure that IP
subnets do not overlap.
Figure 5 – Interface Configuration Settings
If DHCP client, PPPoE, or PPTP is selected as a dial-up protocol for the WAN
interface the WAN settings of this table will be overwritten by the values retrieved
from the Internet Provider.
Step 2. DNS Set-Up
In the network interface | DNS menu you can specify your local domain name server or enter the
DNS server provided by your ISP (Internet Service Provider).
Figure 6 – DNS Redirection
DNS is set automatically if provided by the ISP dynamically via DHCP, PPPoE or
PPTP.
Step 3. IP Address Management
For automatic IP assignments to client stations, set the DHCP settings in the network interface |
DHCP menu according to your TCP/IP configuration from step 1. Only use address ranges within the
corresponding IP subnet of the LAN interface. In addition you can switch on the Universal Address
Translation function in the system | access | UAT menu. With UAT users do not need to change their
local TCP/IP settings to log on to the Access Controller. The Access Controller will translate fixed IP
numbers used in private networks transparently for the user.
Please refer to Chapter 3 – Universal Address Translation for further details to
avoid IP conflicts.
Step 4. RADIUS Set-Up
In the network interface | RADIUS settings menu you can first define the local settings of the
integrated RADIUS client of the Access Controller. For example you can modify timeouts and the
NAS server ID (name of the RADIUS client):
Gemtek Systems Page 19

User’s Guide Installation
Figure 7 – RADIUS Settings
On the second page: network interface | RADIUS servers you can specify up to 32 different
RADIUS servers for authentication and accounting (see Figure 8 – RADIUS Servers). The first line of
this table is the default server (can be configured as default). Thus, if a user cannot be associated to
any specific service provider by his login name, the Access Controller will send authentication and
accounting messages to the first RADIUS server on the list.
Figure 8 – RADIUS Servers
Make sure that the RADIUS server is up and running and is able to receive authentication requests
from the Access Controller.
On the download pages at www.gemtek-systems.com you will find quick installation
guides for common RADIUS servers.
Step 5. Welcome/Login/Start pages
The most popular authentication method for public users is the UAM (Universal Access Method).
UAM can be enabled using the system | access | AAA menu. With UAM users can log-on to the
Access Controller using their web browser. As an operator of a wireless access service you can
provide a custom set of web pages to your subscribers.
