Chapter 1. System Overview
1.1 Introduction of TEW-455APBO
The 802.11 b/g compliant TEW-455APDO is an outdoor wireless device that can be used for five different
purposes in three different modes. In the AP mode, it can be deployed either as traditional fixed wireless
Access Point (AP), or combination of AP and WDS(AP+WDS). In the WDS mode, it’s only used to expand or
bridge Ethernet networks and deployed as a main base, relay based or remote base station. In the CPE mode,
it connects to Wireless Internet Service Provider’s (WISP) outdoor network via wireless WAN gateway to
access to Internet.
The die-cast sealed TEW-455APDO is compact in size and compliant with IP66/IP67 weatherproof standard. It
comes with a mounting kit to mount on pole or wall. It is suitable for both indoor and outdoor usage with its
adjustable output power.
1. Access Point : It can be deployed as a traditional fixed wireless Access Point
2. Repeater: To expand wireless service by repeating prior AP
3. WDS : It can be used to expand Ethernet network via wireless WDS Link
4. AP+WDS: Not only to extend Ethernet network, but also provide wireless access to the expanded
network
5. CPE (Customer Premises Equipment): It is a wireless gateway with NAT and DHCP Server functions to
connects to Wireless Internet Service Provider's (WISP)

1.2 System Concept
The TEW-455APDO is not only designed and used as traditional outdoor AP, but also with rich features tailored
for WISP applications. The two-level management capability and access control ease WISP and owners to
maintain and manage wireless network in a more controllable fashion. Main applications are listed as follows
with illustration:
Wireless CPE for Multi Dwelling Unit/Multi Tenant Unit (MDU/MTU) complexes including apartments,
dormitories, and office complexes.
Outdoor Access Point for school campuses, enterprise campuses, or manufacture plants.
Indoor Access Point for hotels, factories, or warehouses where industrial grade devices are preferred.
Public hotspot operation for café, parks, convention centers, shopping malls, or airports.
Wireless coverage for indoor and outdoor grounds in private resorts, home yards, or golf course
communities.

1.3 Applications in Wireless Network
TEW455APBO is a multiple mode system which can be configured either as a wireless gateway or an access
point as desired. It also can be used WDS link for Ethernet network expansion. This section depicts different
applications on AP Mode, WDS Mode, and CPE Mode.
Configuration in AP Mode (including Access Point + WDS)
An access point can be either a main, relay or remote base station. A main base station is typically
connected to a wired network via the Ethernet port. A relay base station relays data between main base
stations and relay stations or remote base stations with clients. A remote base station is the end point to
accept connections from wireless clients and pass data upwards to a network wirelessly.
Example 1 : Access Point without WDS
It can be deployed as a tradition fixed wireless Access Point
Example 2 : Access Point with WDS
It can be deployed as a tradition fixed wireless Access Point and provides WDS link to expand
network

Configuration in WDS Mode (Pure WDS)
An access point can be either a main, relay or remote base station. A main base station is typically
connected to a wired network via the Ethernet port. A relay base station relays data between main base
stations and relay stations or remote base stations with clients. A remote base station is the end point to
accept connections from wireless clients and pass data upwards to a network wirelessly. In this mode, it
can support single or multiple WDS links and no wireless clients can associate with it though.

Configuration in CPE Mode
It can be used as an Outdoor Customer Premises Equipment (CPE) to receive wireless signal over last mile
application, helping WISPs deliver wireless broadband Internet service to residents and business
customers. In the CPE mode, TEW-455APBO is a gateway enabled with NAT and DHCP Server functions.
The wired clients connected to TEW-455APBO are in different subnet from those connected to Main Base
Station, and, in CPE mode, it does not accept wireless association from wireless clients.

1.6 Wireless Performance 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.
6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz cordless
phones or other wireless remotes operating on the 2.4GHz frequency can potentially drop the wireless
signal. Although the phone may not be in use, the base can still transmit wireless signal. Move the
phone’s base station as far away as possible from your wireless devices.
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.
