2. IP Plan and RF PlanIP Address:

Subnet Mask:

Default Gateway:

Channel Bandwidth: 5MHz or 10MHz

Channel Frequency: As per frequency configured in BS

3. Verification of exact POE for SS

RED GREEN



4. Physical Verification of Power SourceCheck for the stable Power Source where the Power Adaptor for the POE would be connected

Ideal Power Source: 230V AC

5. Physical Installation Procedure

Mounting of Brackets and Ethernet Cable Installation Steps



Pole Mounting

• Position the clamp around the pole (1 - 3 in) in the desired location

• Install and tighten the clamp bolts enough to secure the clamp to the pole.

• Tighten these screws only after antenna pointing.

Pin-outs for Ethernet Cable

Verification of the Ethernet Cable using Cable Tester



6. Grounding Rules

Proper Grounding is a most essential part of the installation process. Grounding on Base Station isdone at Outdoor unit and the POE

Properly Grounded Radio: A grounded radio causes the surge to pass directly to ground

bypassing the radio

• Locate the grounding lug on the CPE at the back panel of the outdoor unit

• Provide a proper grounding conductor long enough to reach from the Outdoor Unit to the

earth ground

• Crimp one end of a grounding cable to the suitable cable lug

Similarly for Grounded POE: In this case the surge will be picked up by the Cat5 cable and since

the POE is grounded the route for the surge is through the POE to ground

Grounding Lug

If incase Grounding Point is not available the same needs to be communicated to the user as this

could cause damage to the port connecting to the POE. Also ensure the installer puts some proper

insulation tape on the grounding LUG

8. AT Trial Deployment Recommendations

a. Subscriber Station should be positioned in line of sight to the base station antenna and betweenthe Inner and Outer coverage radios of the Base Station antenna

b. If the Subscriber station is too close to the Base Station, appropriate antenna downtilt needs to

apply. Following table can be referred to adjust the position of the subscriber station. The values

represent a first order approximation and should only be used as guidance.

c. Subscriber station should be pole mounted on a permanent fixture so that the subscriber stationantenna direction does not change due to wind or external factors.

d. It is recommended not to carry a subscriber station in hand during establishing a link or during

recording critical AT data.



9. Configurations in SS

SS Installation Procedure through WebGui

Log in to the Configurator

Your Subscriber Unit provides a Web-based Configuration for performing advanced

configuration activities. After you install your Subscriber Unit, use the following procedure to

launch the Configuration.

1. Use an Ethernet cable to connect the Ethernet port labeled PC on the PoE adapter to a

network-interface card (NIC) in a PC or network hub. Then connect the other Ethernet port

on the PoE adapter to the Subscriber Unit.

2. Start your Web browser and point it to one of the following default IP addresses:

http://192.168.0.1. The Login page in Figure 3 appears, with your cursor in the User name

field.

3. Enter the default username admin and default case-sensitive password default in the

appropriate fields.

4. Click the OK button to log in. The Information Page appears. This read-only page displays

network, wireless and device information about your installation.

IP Address 192.168.0.55

Subnet Mask 255.255.255.0

Gateway Not Required

X - O v e r



Specify Wireless SettingsAfter logging in to the Configuration, use the following procedure to set the Subscriber

Unit’s wireless settings.

• In the left pane, under WiMAX Setup, click Wireless. The Wireless Settings page

appears.• Set the three groups of parameters as indicated in Table below. These values must

match the ones you entered for the Pico Base Station.

• Click the Apply button. A page tells you that your configuration changes have beensaved, but will not be applied until you reboot the Subscriber Unit.

• Do not reboot the Subscriber Unit at this time. Instead, proceed to “Specify Network

Setup Settings”.



Link Status

Operational

Management VLAN=10

Data VLAN =100



10. Provisioning Check of SS in EMS

SS needs to be provisioned in the EMS by the NOC team. After the discovery of the SS in the Airsync EMSand after successful registration of SS in the EMS SS would be able to communicate with the Backhaul

Network

11. RF Connectivity Check

SS has the LED Support to check the Link Status

RSSI≤

-96dBm 1

-95dBm ≤ RSSI -86 dBm 2

-85dBm ≤ RSSI ≤ -76 dBm 3

-75dBm ≤ RSSI ≤ -61 dBm 4

ON = Connection to LAN established

BLINKING = Connection in use

OFF= No LAN Connection

LAN

ON = Connection to BS Established

OFF= No Connection to BS

ON = CPE is fully operational

BLINKING = CPE is booting or shutting

down

12. Basic commands to check the connectivity throughCLI interface

SSH or Telnet the IP address of SS using Putty or X-Terminal

Basic Commands

Reboot [reboot CPE]

Ifconfig [Check IP & MAC addresses]

Cat/etc/version |grep firmware_name [Check CPE firmware version

Sf [Check Service flow]

Check Logs

dmesg [kernel log]

cat/var/log.message [CPE event log]

cat/tmp/wavesat/wimax.log [Wireless Log]

Check RF Statics

Analog_ctrl get tx_power [Check CPE’s current Tx Power in dBm]

Rssi [Check downlink rssi]

Cinr [Check downlink Cinr]

Lm_ctrl get dl_freq [Check downlinkfrequency]

Lm_ctrl get bsid [Check BS’s Bsid that CPE is connecting to



13. Procedure for throughput test

JPERF can be downloaded from the Software FTP Site. Install JPerf on both the

PC. Connect one PC behind the Base-Station and other behind the CPE. First do the

connectivity check between this PC and then run Server on PC behind BS and Jperf

Client on the PC connected to CPE.
