TP-LINK CPE205 (01) PDF DOCUMENT

The package for the TP-LINK CPE205 contains the following items:

• Pharos CPE

• Passive PoE Adapter

• Power Cord

• Pole Mounting Straps

• Mounting Bracket

• Plastic Wall Anchors (Qty. 2)

• Self-tapping Screws (Qty. 2)

The LEDs on the TP-LINK CPE205 indicate the following statuses:

Signal Strength LEDs (Four LEDs):

• In AP/AP Router Mode: All four LEDs remain solid.

• In Client/Bridge/Repeater/AP Client Router Mode: The number of lit LEDs indicates the wireless signal strength. More lit LEDs mean better signal.

LAN0/LAN1 LEDs:

• On: A device is connected to the port, but there is no activity.

• Flashing: A device is connected to the port, and it is active.

POWER LED:

• On: The CPE is powered on.

The panel of the TP-LINK CPE205 includes:

• Grounding Terminal: For lightning and ESD protection.

• Shielded Ethernet Port LAN0 (Passive PoE IN): Used to connect to the PoE adapter for power and data.

• Shielded Ethernet Port LAN1: An additional Ethernet port.

• RESET button: Used to restore the device to factory default settings.

The Passive PoE Adapter has the following features:

• Remote Reset: Press and hold this button for about 8 seconds until the CPE’s wireless signal strength and LAN LEDs flash to remotely reset the CPE.

• Power LED: The Power LED is on when the passive PoE adapter is working normally.

For optimal performance, ensure a clear line of sight between the wireless devices. An elevated location is recommended, as obstacles like trees, buildings, and large steel structures will weaken the wireless signal.

Install the TP-LINK CPE205 with its front facing the intended signal-receiving device. You can use landmarks to help with orientation. The horizontal beamwidth for the TP-LINK CPE205 is 60°.

Follow these steps to connect the hardware:

1. Connect an Ethernet cable (up to 60m) from the LAN0 (PoE IN) port on the TP-LINK CPE205 to the POE port on the passive PoE adapter. A shielded CAT5e (or above) cable with a ground wire is recommended.

2. Connect another Ethernet cable from the LAN port on the passive PoE adapter to your computer, router, or switch, depending on your network topology.

3. Connect the power cord to the passive PoE adapter and plug it into a power outlet.

4. Once all connections are finished, slide the cover back onto the CPE.

At the selected site, approximately align the TP-LINK CPE205 to the direction that you have oriented and secure it using the included pole mounting straps.

Mounting the adapter is optional. To do so, follow these steps:

1. It is recommended to install the adapter with the Ethernet port facing upward for the most secure attachment.

2. Drill two holes on the wall and insert the plastic wall anchors.

3. Secure the mounting bracket to the wall. Ensure the shoulders at the corners of the mounting bracket are on the outside and pointing upward.

4. Attach the passive PoE adapter to the mounting bracket by sliding it in the direction of the arrows until it locks into place.

Proper grounding is extremely important for outdoor devices. You can use one of two methods:

• Method 1: Use a shielded CAT5e (or above) cable with a ground wire for the connection between the CPE and the provided PoE adapter. This method helps eliminate ESD attacks.

• Method 2: If using a general CAT5e cable, you must connect the grounding terminal of the CPE to an earth ground using a separate grounding cable.

Follow these steps:

1. Before accessing the interface, you must assign a static IP address to your computer in the format 192.168.0.X (where X is a number between 2 and 253, e.g., 192.168.0.10). Set the Subnet mask to 255.255.255.0.

2. Open a web browser and type http://192.168.0.254 into the address bar and press Enter.

3. For the first login, enter “admin” for both User Name and Password. Read and agree to the terms of use, then click Login.

4. You will be prompted to change the default User Name and Password to protect your CPE. For subsequent logins, use the new username and password you create.

Follow these steps in the PharOS Quick Setup:

1. Log in to PharOS and go to the Quick Setup page.

2. For Operation Mode, select Access Point and click Next.

3. For LAN Settings, click Next to keep the default settings.

4. In Wireless AP Settings:

a. Create a new SSID (Network name).

b. Select WPA-PSK/WPA2-PSK for the Security method and create a PSK Password.

c. Enter the distance between the Access Point and the Client in the Distance Setting field.

d. Select the MAXtream checkbox if needed, and click Next.

5. Verify your settings and click Finish to complete the configuration.

Follow these steps in the PharOS Quick Setup:

1. Log in to PharOS and go to the Quick Setup page.

2. For Operation Mode, select Client and click Next.

3. In LAN Settings, change the IP Address to an unused address on the same subnet as the Access Point (e.g., 192.168.0.X, where X is between 2 and 253), and click Next.

4. In Wireless Client Settings:

a. Click Survey, select the SSID of your Access Point from the list, and click Connect.

b. Select WPA-PSK/WPA2-PSK for the Security option, and enter the same PSK password and distance value as the Access Point, then click Next.

5. Verify your settings and click Finish to complete the configuration.

To get the best wireless performance, you can use the Antenna Alignment tool.

1. In the PharOS interface, click Antenna Alignment from the drop-down list in the upper-right corner.

2. Check the box to enable ‘Alignment Beep’.

3. Physically adjust your antenna’s position. The frequency of the beep sound helps estimate the signal strength received. The lower the sound frequency, the stronger the signal strength.

4. Adjust the antenna until the sound frequency is the lowest, which indicates the optimal alignment.

The hardware features for the TP-LINK CPE205 are as follows:

Note:

1. Estimation is based on copper grounding cable and shielded CAT5e cable with ground wire.

3. Please use the included PoE adapter.

The wireless features for the TP-LINK CPE205 are as follows:

Note:

2. Beamwidth values may vary throughout operating frequency.

With the CPE powered on, you can reset it using one of two methods:

Method 1: Via the RESET Button on the CPE. Press and hold the RESET button for about 8 seconds until the CPE’s LEDs for wireless signal strength and LAN flash.

Method 2: Via the Remote Reset Button on the Passive PoE Adapter. Press and hold the Remote Reset button for about 8 seconds until the CPE’s LEDs for wireless signal strength and LAN flash.

To maximize the received signal strength, you need to minimize the effect of out-of-phase signals caused by obstacles. The Fresnel Zone is a method to calculate the required clearance. The formula for the Fresnel zone radius (r) is:
r = √( (d₁ * d₂) / (d₁ + d₂) * c / f )

Where:
• r = Fresnel zone radius in meters
• c = 3×10⁸ m/s, speed of light
• f = operating frequency of the devices in Hz
• d₁ & d₂ = the distances between the obstacle and each device in meters.

The mounting height (H) of the CPE should be greater than the height of the obstacle (h) plus at least 60% of the Fresnel zone radius (r), or H > h + r * (1 – 40%).

For example, if d₁ is 2 km, d₂ is 8 km, and f is 2.4 GHz, then r is 14.142 m. Allowing for 40% toleration, the allowable radius is 8.485 m. If an obstacle (h) is 10 m high, the minimum mounting height would be 10 m + 8.485 m = 18.485 m. You should calculate this for all obstacles and use the maximum calculated value as the final minimum mounting height.

Pharos MAXtream is a proprietary protocol from TP-Link based on Time Division Multiple Access (TDMA). By dividing transmission timing into different time slots, it allows devices to transmit one after another, reducing collisions. Its advantages include:

• Eliminates hidden node collisions and improves channel efficiency.

• Lower latency, higher throughput, larger network capacity, and more stability.

• Improves the QoS for video, voice, and sound data streams.

Please note that Pharos MAXtream is a non-standard Wi-Fi protocol and is only compatible with other TP-Link Pharos series products. You cannot connect other standard Wi-Fi devices to an AP that has MAXtream enabled.

Follow these steps:

1. Log in to PharOS. From the ‘Tools’ drop-down list, click Spectrum Analysis. A window will pop up to remind you that wireless connections will be lost during the analysis. Click Yes to continue.

2. Click Start. The Pharos will begin to analyze the power of frequencies.

3. Observe the curves for a period of time, then click Stop.

4. The graph shows radio noise across frequencies. A relatively low and continuous part of the average curve indicates less radio noise. You should choose a channel/frequency that avoids the spectrum with large radio noise.
