Product Benefit
The 10 dBi Outdoor PoE Access Point is the point of connection to Wireless Outdoor Network for service provider deploying last mile services to business or residential broadband subscribers.. Network administrators can create multiple subscriber service tier using per-subscriber rate limiting features, and manage centrally.
Installation Considerations
There are a number of factors that can impact the range of wireless devices.
1.Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an angle. The more material the signal has to pass through the more signal you will lose.
2.Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a wireless device. Position the wireless devices in a manner that will minimize the amount of obstructions between them.
3.Building materials can have a large impact on your wireless signal. In an indoor environment, try to position the wireless devices so that the signal passes through less dense material such as dry wall. Dense materials like metal, solid wood, glass or even furniture may block or degrade the signal.
4.Antenna orientation can also have a large impact on your wireless signal. Use the wireless adapter’s site survey tool to determine the best antenna orientation for your wireless devices.
5.Interference from devices that produce RF (radio frequency) noise can also impact your signal. Position your wireless devices away from anything that generates RF noise, such as microwaves, radios and baby monitors.
If you are still experiencing low or no signal consider repositioning the wireless devices or installing additional access points. The use of higher gain antennas may also provide the necessary coverage depending on the environment.
TEW-738APBO

Configuring QoS options consists of setting parameters on existing queues for different types of wireless traffic. You can configure different minimum and maximum wait times for the transmission of packets in each queue based on the requirements of the media being sent. Queues automatically provide minimum transmission delay for Voice, Video, multimedia, and mission critical applications, and rely on best-effort parameters for traditional IP data.
As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher priority for transmission (lower wait times for channel access), while other applications and traditional IP data which are less time-sensitive but often more dataintensive are expected to tolerate longer wait times.
o Aifsn: The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds) for data frames
oCWmin: Minimum Contention Window. This parameter is input to the algorithm that determines the initial random back-off wait time ("window") for retry of a transmission. The value specified here in the Minimum Contention Window is the upper limit (in milliseconds) of a range from which the initial random back-off
wait time is determined.
oCWmax: Maximum Contention Window. The value specified here in the Maximum Contention Window is the upper limit (in milliseconds) for the doubling of the random back-off value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for "cwmax" must be higher than the value for
"cwmin".

When the no acknowledgment (No ACK) policy is used, the recipient does not acknowledge received packets during wireless packet exchange. This policy is suitable in the environment where communication quality is fine and interference is weak. While the No ACK policy helps improve transmission efficiency, it can cause increased packet loss when communication quality deteriorates. This is because when this policy is used, a sender does not retransmit packets that have not been received by the recipient. When the Normal ACK policy is used, the recipient acknowledges each received unicast packet.

Wireless MAC Filter Setup |
Wireless Network Expansion |
Continue Virtual AP Setup section. For each Virtual AP setting, the administrator can allow or reject clients to access each Virtual AP.
The administrator could create WDS Links to expand wireless network. When WDS is enabled, access point functions as a wireless bridge and is able to communicate with other access points via WDS links. A WDS link is bidirectional and both side must support WDS. Access points know each other by MAC Address. In other words, each access point needs to include MAC address of its peer. Ensure all access points are configured with the same channel and own same security type settings.
Remote Bass Station
•MAC Filter Setup: By default, it’s “Disable”. Options are Disable, Only Deny List MAC or Only Allow List MAC.
Two ways to set MAC filter rules:
o Only Allow List MAC: The wireless clients in the “Enable” list will be allowed to access the Access Point; All others or clients in the “Disable” list will be denied.
o Only Deny List MAC: The wireless clients in the “Enable” list will be denied to access the Access Point; All others or clients in the “Disable” list will be allowed.
Add a station MAC: Enter MAC address (e.g. aa:bb:cc:00:00:0a) and click “Add” button, then the MAC address should display in the “Enable” List.
There are a maximum of 20 clients allowed in this “Enable” List. The MAC addresses of the wireless clients can be added and removed to the list using the Add and Remove buttons. Click Reboot button to activate your changes
