Overview the Product Introduction The high-performance Wireless Network Access Point (AP) is designed for enterprise and public access applications. Embedded with the Atheros chipset, it boasts network robustness, stability and wider network coverage. Based on 802.11n (Draft 2.0), the access point supports high-speed data transmission of up to 300Mbps.
Features and Benefits Point-to-Point & Point-to-MultiPoint Support Point-to-Point and Point-to-MultiPoint communication between different buildings enables you to bridge wireless clients that are kilometres apart while unifying the networks. Virtual AP (Multiple SSID) Virtual AP implements mSSID (Multi-SSID) This allows a single wireless card to be set up with multiple virtual AP connections with different SSIDs or BSSID (Basic Service Set Identifier) and security modes.
Operation Modes and Connection Examples Access Point and Access Point WDS Mode The Access Point Mode is the default mode of the device. It enables the bridging of wireless clients to wired network infrastructure and enables transparent access and communication with each other. The illustration below shows a typical resources sharing application example using this device. The wireless users are able to access the file server connected to the switch, through the access point in Access Point Mode.
Station Mode In Station mode the device acts as a wireless client. When connected to an access point, it creates a network link between the Ethernet network connected at this client device, and the wireless Ethernet network connected at the access point. In this example the workgroup PCs on the ethernet network connected to the Station device can access the printer across the wireless connection to the access point where the printer is connected.
Station WDS Mode Station WDS mode is similar to Station mode. The difference is Station WDS must connect to access point configured to Access Point WDS (or RootAP) mode. Station WDS is mainly use for point-to–point connection between 2 buildings or locations as far as several kilometer away. Point-to-Point An access point setup as Access Point WDS (or RootAP) and other as Station WDS (Transparent Client).
Router Mode In Router Mode, the device also operates as a router. Either the wireless or Ethernet can be setup as WAN connection to a broadband modem. Wireless as WAN is known as Station + Router mode (or Wireless Routing Client mode) and Ethernet as WAN is known as AP + Router mode (or Gateway mode). Device supports several types of broadband connections Static IP, Dynamic IP and PPPoE. For setup details refer to the respective section.
Repeater WDS Mode Repeater WDS Mode to mainly to extend the wireless range and coverage of the wireless network allowing access and communications over places generally difficult for wireless clients to connect to the network. In Repeater mode, the access point acts as a relay for network signals on the network by regenerating the signals it receives, and retransmitting them to main network infrastructure. Detailed information on the Repeater mode is available in the Repeater Setup section.

Install the Hardware This section will show you how to install the hardware of the access point. • Antenna Alignment The antenna alignment of the access point must first be considered to ensure that the signal is strong. • Installation Direction After considering the antenna alignment, the direction in which the access point is facing must be considered to ensure that the signal is actually being directed to the receiving end.
Antenna Alignment The physical environment of the antenna must be examined when aligning the antenna. Obstructions, available mounting locations, and other factors must be considered. Many objects such as forests, buildings, and hills, can obstruct the antenna, reducing the signal strength. The antenna can be installed at a height above such obstructions, and aligned so that antennas are directed at each other by taking into account the horizontal angle and the vertical angle of the antenna signal.
Installation Direction The directional antenna radiates the signal towards the front of the unit. The unit should be installed in a position whereby the front of the unit faces the direction you wish to send the signal to. Therefore the direction you wish to send the signal to has to be considered before going on to the next step of starting to set up the access point.

Appendix I - Network This section provides more detailed explanation on the network operation modes in general. The Network Page allows the administrator to setup bridge or routing functionality. Device can operate in bridge or router mode. The IP configuration as described below is required for device management purposes. IP addresses can either be retrieved from a DHCP server or configured manually. Use the Network menu to configure the IP settings.
Bridge IP Address: The device can be set for static IP or can be set to obtain an IP address from the DHCP server it is connected to. One of the IP assignment modes must be selected: DHCP : choose this option to assign the dynamic IP address, Gateway and DNS address by the local DHCP server. STATIC : choose this option to assign the static IP settings for the bridge interface. IP Address: enter the IP address of the device while Static Bridge IP Address mode is selected.
Spanning Tree Protocol: Multiple interconnected bridges create larger networks using the IEEE 802.1d Spanning Tree Protocol (STP), which is used for finding the shortest path within network and to eliminate loops from the topology. If the STP is turned on, the Bridge device will communicate with other network devices by sending and receiving Bridge Protocol Data Units (BPDU).
Appendix II – Wireless with Router Mode This section provides more details on wireless with router function.
Gateway IP: This is the IP address of the host router which resides on the external network and provides the point of connection to the next hop towards the internet. This can be a DSL modem, Cable modem, or a WISP gateway router. The device will direct all the packets to the gateway if the destination host is not within the local network.
Port Forwarding Settings Port Forwarding: Port forwarding allows specific ports of the hosts residing in the internal network to be forwarded to the external network. This is useful for number of applications such as FTP servers, gaming, etc. where different host systems need to be seen using a single common IP address/port. Port Forwarding rules can be set in Port Forwarding window, which is opened by enabling the Port Forwarding option and activating the Configure button.
Bridge mode Firewall Configuration Settings Firewall functionality on any router interface can be enabled using the "Enable Firewall" option. Router Firewall rules can be configured, enabled or disabled while using Firewall configuration window which is opened with the "Configure" button.
Enable DMZ: The Demilitarized zone (DMZ) can be enabled and used as a place where services can be placed such as Web Servers, Proxy Servers, and E-mail Servers such that these services can still serve the local network and are at the same time isolated from it for additional security. DMZ is commonly used with the NAT functionality as an alternative for the Port Forwarding while makes all the ports of the host network device be visible from the external network side.
Appendix III- Advanced Settings This section provides more detail explanation on advanced setting for routing and wireless settings. The Advanced options page allows you to manage advanced settings that influence on the device performance and behavior. The advanced wireless settings are dedicated for more technically advanced users who have a sufficient knowledge about wireless LAN technology. These settings should not be changed unless you know what effect the changes will have on your device.
Fragmentation Threshold: specifies the maximum size for a packet before data is fragmented into multiple packets. The range is 256-2346 bytes, or word “off”. Setting the Fragmentation Threshold too low may result in poor network performance. The use of fragmentation can increase the reliability of frame transmissions. Because of sending smaller frames, collisions are much less likely to occur. However lower values of the Fragmentation Threshold will result lower throughput as well.
Signal Strength LED Settings LED Thresholds Configuration The LED's for signal strength on the device can be made to light on when received signal levels reach the values defined in the following fields. This allows a technician to easily deploy a CPE without logging into the unit (i.e. for antenna alignment operation).
Appendix IV- Services This section provides more details on the system management services. Ping WatchDog The ping watchdog sets the device to continuously ping a user defined IP address (it can be the internet gateway for example). If it is unable to ping under the user defined constraints, the device will automatically reboot. This option creates a kind of "fail-proof" mechanism. Ping Watchdog is dedicated for continuous monitoring of the particular connection to remote host using the Ping tool.
NTP Client, Web, Telnet, SSH Server NTP Client: The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. It can be used to set the device system time. System Time is reported next to the every System Log entry while registering system events if Log option is enabled.
