2-4 Hardware Installation
The 4.9GHz outdoor subscriber is a radio device, so it is susceptible to common causes
of interference that can reduce throughput and range. Follow these basic guidelines to
ensure the best possible performance:
¾ IF there is any other 4.9GHz RF device deployed around the outdoor radio, try to set
the channel to the non-overlapping one.
¾ Install the bridge at a height sufficient place where structures, trees, or hills do not
obstruct radio signals to and from the unit. A clear line-of-sight path can guarantee the
performance of the RF link.
Site Surveys
Clear and flat area provide better RF range and data rate, on the contrary, physical
obstructions such as trees, electric tower, hills or buildings can reduce the
performance of RF devices. Do not deploy your radios in the location where there is
any obstacle between the antennas.

Advanced Parameters
RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden
Node” problem. If the size of the packet transmitted is larger than the value you set, the
RTS will be enabled. When the RTS is activated, the Wireless Bridge will use a
(RTS/CTS) mechanism for data transmission. The setting range is 0-2346.
Fragmentation Length: Fragmentation mechanism is used for improving the efficiency
when there is high traffic within the wireless network. If you transmit large files in a
wireless network, you can enable the Fragmentation Threshold and specify the packet
size. This specifies the maximum size a data packet will be before splitting and creating a
new packet. The setting range is 256-2346. For example: If you set value as 256, it
means the packet will be fragmented into “256” bytes while transmitting.
Beacon Interval: This value indicates the frequency interval of the beacon. A beacon is
a packet broadcast by the outdoor radio to keep the network synchronized. A beacon
includes the wireless LAN service area, the outdoor radio address, the Broadcast
destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic
Indicator Message (TIM).
Space In Meter: This is used for extending ACK time-out destination. The setting range is
0-10000 m. The longer is the distance, the lower the throughput.
Note: please set the value in this field according to the true distance, the value you
set will affect the performance of the throughput. Our default value is 1000m.
Time Slice: set the time slice of the VQOS / TDM.

VAP / VLAN Settings
As the number of data-based systems increase, it becomes more and more difficult to provide
the network infrastructure (due to the sheer number of Ethernet connections that need to be
provided) from the perspective of cost, space, and wire management. Luckily, the advent
technology called VLAN (Virtual Local Area Network) can achieve her mission. Now it is
possible for these multi devices in function without the need for multiple physical network
APs.
See the diagram below.
Under this mode, this radio can behave as 8 virtual Wireless LAN infrastructures. You
can specify unique SSID for these different infrastructures. For example, VLAN1 contains
ETH1 and STA1, VLAN2 contains ETH2 and STA2, and so on. However, they all share
23
the same AP and undertake different tasks. Some VLANs can be used for guest Internet
access, others for enterprise users, and administrators can be put on a high security
VLAN with enhanced firewall permissions. All this can be achieved using a single
infrastructure to emulate up to 8 infrastructures. The AP does this by assigning each of
the 8 VLANs it’s own SSID, so you will think you are looking at up to 8different wireless
networks.
Enable this function to let associated clients be able to separate from each other when
security is required. The default setting is Disable.
Note: If you complete the settings, please click on “Apply” for changes to take effect.
Wireless Setup / Encryption Settings
To prevent unauthorized radios from accessing data transmitted over the link, the
Encryption Settings window offers WEP features, making your data transmission over air
more secure and allows you to specify Encryption Key(s) if you enable encryption for the
Wireless Bridge. There are three degrees of encryption could be selected: 64 bits WEP,
128 bits WEP and 152 bits WEP. Also you can select WPA-PSK and WPA2-PSK for the
advance security.
24
The following elaborate WEP/WPA security options.
Field Description
Network
Authentication
You have two authentication options.
• Open System:
No authentication is imposed to the radio. However, if the 802.1x
option is configured, authentication of connections can be
performed by a RADIUS server.
• Shared: this is for shared key authentication. Data is encrypted.
25
Encryption
Strength
You can select the following data encryption options: Disabled
64- 128- or 152-bit WEP With Open System Authentication and 64-
128- or 152-bit WEP Data Encryption with Shared Key
authentication
Security
Encryption (WEP)
Keys
WEP enabled, you can manually enter the four data encryption
keys or enable Passphrase to generate the keys automatically.
These values must be matched between all Clients and access
points at your LAN (key 1 must be the same for all, key 2 must be
the same for all, etc.)
Two ways to create WEP encryption keys:
• Passphrase.
Passphrase functions as automatically case-sensitive characters.
However, not all wireless adapters support passphrase key
generation.
• Manual. These values are not case sensitive. 64-bit WEP: enter
10 hexadecimal digits (any combination of 0-9, a-f, or A-F). 128-bit
WEP: enter 26 hexadecimal digits (any combination of 0-9, a-f, or
A-F). 152-bit WEP: enter 32 hexadecimal digits (any combination of
0-9, a-f, or A-F).
WPA-PSK (Wi-Fi
Protected Access
Pre-Shared Key)
WPA Pre-Shared-Key uses a pre-shared key to perform the
authentication and generate the initial data encryption keys. Then, it
dynamically varies the encryption key. It uses Temporal Key
Integrity Protocol (TKIP) for encryption keys. However not all
wireless adapters support WPA. Furthermore, client software is
required on the client. Windows XP and Windows 2000 with Service
Pack 3 do include the client software that supports WPA.
Nevertheless, the wireless adapter hardware and driver must also
support WPA.
WPA 2-PSK Identical to WPA-PSK with the exception of the way to encryption
keys. WPA2-PSK uses Advanced Encryption Standard (AES) for
encryption keys.
WPA-PSK& WPA
2-PSK
You may have the option of WPA-PSK associated with TKIP.
Alternatively, you can select WPA2-PSK associated with AES.
26
Note: WPA-PSK (TKIP) & WPA2-PSK (AES) only works at Base station and
CPE mode.

Appendix A: Trouble shooting
This Appendix helps you to isolate and solve the problems with the 4.9GHz
outdoor subscriber. Before you start troubleshooting, it is important that you have
checked the details in the product user manual and QIG.
In some cases, rebooting the unit clears the problem. If the radio still can’t work
well, please try to contact your local vendor or supplier.
General Descriptions
To successfully use the radios, engineers must be able to troubleshoot the system
effectively. This section will show you how an 4.9GHz outdoor subscriber could be
analyzed in the case of “no link,” usually, we thinks that the link is down because there is
no traffic being passed. The four main reasons that a link may not work are list as below:
Configuration
Path issues (such as distance, obstacles, RF reflection…)
Personal reasons (careless mounting or the incorrectly connection.)
Hardware (includes the radio, cable and connectors…etc. In few cases, the radio will
conflict with the laptop or PC)
Environment (anything that is outside the equipment and not part of the path itself)
After verified the correct configuration, double-checked the path terms, ensure no
personal reasons and the hardware works well in the office, but the user still report that
the link does not work. Most likely, the problem reported is caused by the environment or
by improper tests to verify the connection. Assumes that the test method, cabling,
antennas, and antenna alignment have been checked, (Always ensure this before
checking the environment.) then you can do the follow to check the environment.
General Check
Two general checks are recommended before taking any action:
Check whether the software version at both sides is the most current
Check for any reported alarm messages in the Event Log
Analyzing the Spectrum
The best way to discover if there is a source of interference is to use the spectrum
analyzer. By turning the antenna 360 degrees, you can find out which direction is the
interference coming from. it will also show the frequencies and the level of signal is
detected.
Avoiding Interference
When a source of interference is identified and when the level and frequencies are known,
the next step is to avoid the interference. Some of the following actions can be tried:
Change the RF channel to the one away from the interference source
802.11a Outdoor Multi-function Radio User Manual

Change the polarization of the antenna; try to change to a polarization different
from the interferer.
A small beam antenna may helps. (Such as some grid or dish antenna, align the
antenna in to the particular direction will reduce the affects from the interference
source) This solution cannot help when the source of interference is right behind
the remote site.
Before checking for interference, ensure all the hardware works well and configurations
are correct. The path analysis, cabling and antennas should be checked as well.
Connection Issues
This section describes several common troubles the customer might have while setting
the radios.
Radio Does Not Boot
When the Radio does not Boot, do the following steps to check your whole system:
1. Ensure that the power supply is properly working and correctly connected.
2. Ensure that all cables are workable and connected correctly.
3. Check the power source.
Cannot use the Web Interface
If the radio boot, but can’t enter it via the Web site.
1. Open a command prompt window and enter ping <ip address unit> (for example:
ping 192.168.1.1). If there is no response from the radio, make sure that you the
IP address is correct. If there is response, the Ethernet connection is working properly,
do the next step.
2. Make sure that you are using one of the following Web browsers:
Microsoft Internet Explorer version 5.0 or later
Netscape version 5.0 or later.
3. Ensure that you are not using a proxy server for the connection with your Web
browser.
Double-check the physical network connections (includes the cables and the connectors).
Use a well-known unit to ensure the network connection is properly functioning.
Configuration Issues
The following problems relate to setup and configuration problems.
Some basic configurations might make the link fail, below are the major ones:
RF Channel
SSID
IP address
Rule of MAC address filter
Rule of security settings (such as WEP or WPA)
34
Rule of authentication (such as settings of radius server and 802.1x)
Configurations of WDS page
If the links of the two radios works within close distance of each other, then there are two
possible reasons why wireless connectivity is not possible while the 4.9GHz outdoor
subscribers are at their desired locations:
RF path, for example, a bad antenna alignment, the tower is not tall enough when
the radios are installed in a long distance or the connector do not attachment
well…etc (these are the most common problems in installations)
Interference problem caused by a high signal level from another unit. The
interference can be checked by changing the frequency and then see if another
channel works better. Or you can change the polarization of the antenna as a way of
avoiding the interfering signal. To know in advance how much interference is present
in a given environment, a Spectrum Analyzer can be attached to a (temporary)
antenna for measuring the signal levels on all available Channels.
If the link still not works after resetting the configurations, checking the
connectors and cables, double-check the path and environment issues, then the
problem is possible a hardware problem. Acquiring a third radio and then
testing it amongst the existing units will help to find out the broken unit.
