Line-of-Sight

• Fresnel Zone– http://en.wikipedia.org/wiki/Fresnel_zone

– The antenna should be installed at more than a certain height.

Source: Wikipedia, 2010


[email protected]

LOS and Fresnel Zone

• Install the antennas at places which is high enough for LOS transmission.

• For example, installing at higher places to avoid traffic or building landscape– By the ground– By road traffic– By an obstacle

Source: Wikipedia, 2010


[email protected]

Line-of-Sight

If there is a tree between the two nodes, then the antenna should be installed at a higher location to avoid the tree obstacle, trying to calculate the height roughly by the Fresnel Zone formula.

CSMA & TDMA

• TDMA can transmit up to 40km, but only with PtP Configuration– 21Mbps with Link Aggregation (R2)

– 12Mbps without Link Aggregation (R1 or R2)

• CSMA can transmit up to 20km, with PtP or PtMP Configuration– 27Mbps with Link Aggregation (R2)

– 14~18Mbps without Link Aggregation (R1 or R2)

Security Features

• Network Authentication• Data Encryption• Hide SSID: Avoid accessed

by rovering• Wireless Client Isolation Mo

de• Access Control List• Radius Support/Settings

– Primary Radius Server– Secondary Radius Server

• Remote Management• SNMP• Time Setting• GPS Coordinate Setting• Remote Firmware Upgrade• SysLog Server

Features

• Distance in Meters• Spanning Tree Protocol

– STP Forward Delay• VLAN 802.1Q

– Management VLAN ID• System Monitor

– Software-triggered Watchdog Reset• Adjustable Output Power• Selectable Bandwidth: 5/10/20/40 MHz• TDM Coordination

– TDM Coordination Time Slice• NoACK

– Under TDMA mode, enabling NoACK can enhance throughput but it might result in higher error rates in a noisy environment.

• WMM(Wi-fi Multi-media)• Super Mode


[email protected]

Features

• Uplink Speed Limit• P2MP

– Set by MAC address– Set by Group ID

• Antenna Alignment Tool– A very useful feature using BEEP frequency when your are

adjusting the antenna• Link Test• Broadcast SSID

– Hiding network name is necessary when you are in a wireless environment that may have potential risk. By disabling broadcast SSID, the STA cannot scan and find the IEEE 802.11a/n Wireless Outdoor CPE, so that malicious attack by some illegal STA could be avoided.

Other Considerations

• Surge Protector– Ground the device properly with grounding wire to

protect against lightning

• Lightning Arrester• Grounding• Hard Reset• Hard Reset to Factory Default Setting• EMD (Lightning) DAMAGE IS NOT

COVERED UNDER WARRNTY

• If there are a lot of smog and fog, when such extreme conditions, how to overcome the throughput degrade problem with the transmission of data getting slower– technically speaking, the transimission effectiveness is a function of (System

Transmission Power) + (Antenna Gain) - (Media Loss)– When it's foggy, it means that the (Media Loss) getting bigger. There are som

e ways to improve it:• Use an antenna with bigger (Antenna Gain). But, bigger the antenna gain, sm

aller the beam angle• Increase the (System Transmission Power): it means that you should use som

ething like external Booster.• You may use additional Z9000R2 as a relay in between the two Z9000R1 that

it will shorten the hop-distance and get better throughput.• Use some devices running at 700MHz or 900MHz band. Essentially, the lower

the band frequency the signal is, the higher the signal penetration. The problem is that you need to change all the system, and the 700/900MHz may be the licenced band in your country. Furthermore, you need to have field-trial to know the exact effectiveness.

• What if the signal quality is poor or not so good?– Check whether there is obstacle between units. Obstacle may lead

to poor signal.– Check the antenna height. Place the unit in a high position can help

to get a better communication in long distance transmission.– Check the polarization direction of antenna. Keep the polarization

direction of antennas on two associating units the same; if not (one is horizontal, another is vertical), the signal quality may reduce dramatically.

– Check the antenna angle. Align the antenna to the remote one if using directional antenna. Big angle shift may lead to poor signal.

– Check the feeder length. Too long feeder may increase the signal loss and affect the unit performance.
