Chapter 1 – Introduction
Thank you for choosing the Gemtek Systems 54Mbps Operator Access Point model P-520.
The Gemtek Systems P-520 is a Carrier-Grade Wi-Fi Access Point designed to provide reliable and
secure wireless access to an operator network or enterprise LAN. Theft-proof mounted to a wall or
ceiling the access point can be fully configured and controlled from a central management system
minimizing the need for an engineer to physically access the unit once it has been installed.
Product Overview
High Performance for Maximum Coverage
The Gemtek Systems P-520 Operator Access Point provides quality connectivity for Wi-Fi networks.
Designed to support even the largest of Hot Spots, this AP combines high receiver sensitivity and
proven antenna technology to maximize coverage.
Wi-Fi Compliance to Ensure Network Compatibility
Tested for interoperability with the Wi-Fi standard, the P-520 will support all Wi-Fi certified client
devices; the global industry-standard for local wireless networking.
The Perfect Access Point for Large Areas
The P-520 is specifically designed for large venues. Connected to a Access Controller like the
Gemtek Systems G6000 or P-560, P-520s can easily cover a hotspot of any size. P-520 is IEEE
802.3af compliant, enabling it to be powered over standard Cat-5 Ethernet cabling, reducing
installation and maintenance costs.
Total Management
The P-520 Operator Access Point simplifies the set-up, operation, control and management of public
access networks. The AP can be remotely managed via HTTP or SNMP. Auto-channel selection and
integrated site survey utilities help administrators to optimize cell planning.
Security
P-520 supports various state-of-the-art security mechanisms like WPA, Access Control Lists,
802.1x/EAP authentication and Layer 2 User Isolation. The User Isolation feature can effectively
prevent peer-to-peer communication between client stations. The AP is designed for wall mount with
integrated theft-protection.

User’s Guide Chapter 1 – Introduction
Management Options
There are several managing and monitoring interfaces available to the operator to configure and
manage the P-520 on your network:
This user manual provides detailed description of Web and SNMP management option.
Web Interface
The Web-browser interface (also known as the HTTP interface) provides easy access to configuration
settings and network statistics from any computer in the network. Use the Web browser interface
through your LAN (switch, hub, etc.), over the Internet, or with a “crossover” Ethernet cable connected
directly to your computer’s Ethernet Port.
SNMP Management
In addition to the Web interface, you can also manage and configure a P-520 using the Simple
Network Management Protocol (SNMP). SNMP enables network administrators to manage network
performance, find and solve network problems, and plan for network growth.
In order to manage the device you have to provide your Network Management
System software with adequate MIB files. Please consult your management
software manuals on how to do that.

Operating Modes
The P-520 Access Point can work in different operating modes:
Access Point (AP) mode:
In AP mode the P-520 can connect multiple wireless client stations to a wired network. The Local
Area Network and the Wireless Network are from the same IP address space.
Gemtek Systems Page 10
User’s Guide Chapter 1 – Introduction
Access Point with WDS (Wireless Bridge and Wireless Repeater) mode:
A WDS (Wireless Distribution System) allows you to create a wireless network infrastructure.
Normally, the access points must be connected with a wire (LAN), which is generally an Ethernet
connection in business applications. Once connected, these access points create wireless cells
allowing a wireless connection. The WDS feature allows the access points to be wirelessly connected
to another access point, eliminating the need to the wired connection between them. Two WDS
configurations are described in the following pictures: wireless bridge and wirelessrepeater.
Gemtek Systems Page 11
User’s Guide Chapter 1 – Introduction
Wireless Bridge:
The first use of the WDS, Wireless Bridge mode is to create the wireless bridge between two or
more wired networks, for example networks in different buildings with no wired connections between
them. All APs in a WDS have to be configured for the same radio channel and must be configured
with their WDS partner AP BSSIDs (MAC addresses). The data being transported is bridged
transparently; i.e., the data received by the LAN station is identical to data that would be received if
both LAN stations had been connected to the same LAN subnet.
Gemtek Systems Page 12
User’s Guide Chapter 1 – Introduction
Wireless Repeater:
The other use of the WDS,WirelessRepeater mode is to extend wireless area coverage between
wired and wireless networks. This mode is normally used in large, open areas, where pulling a wire is
prohibited or not cost effective and in residential circumstances. By settings up the BSSIDs (MAC
addresses) between AP’s WDS partners, stations can intersect with any AP of this BSSID and move
between the coverage of both APs.
In both cases, the P-520 acts as a network bridge between wireless and wired networks. All data
received by the P-520 on its wireless or Ethernet interface is broadcast on the wireless interface to all
connected devices that are authorized in the ACL (access control list).
Antenna Diversity
The P-520 Operator Access Point uses antenna diversity to select the best reception signal at the two
integrated antennas. Antenna diversity counters the adverse effects of multi-path fading and antenna
pattern nulls and reduces the packet error rate.
The main antenna (at internal connector J4) is used for transmission whereas both antennas, main
and aux, can receiving signals. Receive diversity examines only packets directed at the AP. A count
of frames received consecutively with FCS errors is compared to the configured threshold value.
When this value is reached, the receive antenna used is switched to the other antenna. If a directed
frame is received without errors the error count is reset back to zero.
