Chapter 1: Introduce
1.1 Introduce
The AirLive WH-9100MESH product is ruggedized and wall-mountable IEEE 802.11 Wireless Access
Point (AP) and Bridge device. The AP and Bridge mode can work simultaneously by dual radio
interfaces. The WH-9100MESH serial products are designed for use in industrial and outdoor
environments. They are powered by the Power over Ethernet (PoE) to simple cabling installations. So,
they are suitable to set up at outdoor environment and using AP function to provide wireless network
service and Bridge function to link to another location where is within infrastructure network.
The WH-9100MESH product is designed as a high security wireless network device. They are with the
following cryptographic modules: WEP (64,128or 152 bits), WPA (TKIP / AES-CCMP) or WPA2 in AP
mode, and AES-CCMP (128 bits) for the bridging mode; and HTTPS/TLS for secure web
communication. Moreover, the WH-9100MESH serial products also provide the wireless client MAC
address filtering, Rogue AP detection to protect your wireless network.
There are serial of products for you choose. The 9100MESH is the basic line product works at 2.4GHz
band (802.11b/g) and 5GHz (802.11a) with AP and bridge function. The 9100MESH also provides
Super G / Turbo A function to enhance transmit data rate up to 108Mbps. (Turbo A mode doesn’t
support at ETSI domain region.) The 9100MESH adopts newest 802.11i WPA2 standard to enhance
the wireless security. The major feature of 9100MESH is Wireless Mesh Network function and
introduce at section 1.1.3. The 9100MESH works at 2.4GHz and 5GHz band too. The 9100MESH also
provides Gateway mode, Layer 2 (Client) isolation, Multiple SSID/VLAN and Gateway Mode
features. When 9100MESH set up at Gateway mode, it provides firewall function to enhance network
security.
1.1.1 802.11g Super and 802.11a Turbo:
802.11g Super and 802.11a Turbo technologies provide speed and throughput of more than double
standard wireless LAN technologies in networking products. The Maximum link speed available is
108Mbps and the typical maximum end-user throughput ranges from approximately 40Mbps to
60+Mbps, depending on application demand and network environment.
1.1.2 Wireless Mesh Network:
The mesh network function let you set up the point-to-multipoint bridge function easily. You don’t need
to key in each remote bridge’s BSSID (WLAN MAC address) to form bridge topology. It calls as
auto-forming function. Beside the auto-forming function, it also detects network topology status. If some
of bridge devices are log out, the other devices will find out it and re-forming network topology again.
This is also call as auto-hearing function.
1.1.4 AP Mode vs. Gateway Mode
At AP mode, IP address for wireless devices are typically assigned by the wired network’s DHCP server.
The AP virtually connects wireless users to the host wired network. All wireless devices connected to
the AP are configured on the same sub network as the wired network interface and can be accessed by
AirLive WH-9100-MESH User’s Manual
5

devices on the wired network.
Unlike the AP mode that the wireless clients get IP address from upstream network equipment and is at
the same sub-network with wired network interface. Gateway mode provides private IP address for the
wireless clients and is different sub-network from wired network interface. Gateway mode takes
advantage of some built-in “router” function, such as the Network Address Translation (NAT) and
Firewall. The NAT provides private IP address for the wireless clients and the Firewall enhance the
security of wireless network.
Figure 1-1: Gateway mode vs. Access Point Mode
1.1.5 Multiple SSID/VLAN:
The Multiple SSID function working with VLAN switch provides the feature that different level clients link
to one AP with different privilege.
Traditional AP only provides one SSID. All clients link to this SSID are in same network domain with
same privilege. If you want different level clients link to different network domain with different privilege,
AirLive WH-9100-MESH User’s Manual
6

you need use another AP with different SSID name. And those APs link to different wire network
domains to provide different privilege.
The Multiple SSID AP can provide couples SSID in one device. A VLAN Switch provides a
switched network that is logically segmented by function, project team, or application in the
same physical LAN. Within Multiple SSID AP and VLAN Switch, each SSID is associated
with a VLAN to provide different privilege to distinguish different level client. Different level
clients can link to same AP by different SSID with different privilege.
1.1.6 Layer 2 (Client) Isolation
The Layer 2 (Client) Isolation function can protect your computer to prevent other users in the
same network domain log in your computer to access data.

Chapter 2: System Installation
The manual deals only and specifically with the single device as a unit. The purpose of this chapter is
the description of the device and its identifiable parts so that the user is sufficiently familiar to
interact with the physical unit.
Preliminary setup information provided below is intended for information and instruction of the
wireless LAN system administration personnel.
It is intended, and is the philosophy of the manufacturer, that the user not be required to open the
individual unit. Any maintenance required is limited to the external enclosure surface, cable
connections and to the management software only. A failed unit should be returned to the manufacturer
for maintenance.
2.1 Prepare for use
The WH-9100MESH is designed to be attached to the wall at appropriate locations. To complete
the configuration, you should have at least the following components:
yPCs with one of the following operation systems installed: Windows NT 4.0, Windows 2000 or
Windows XP;
yA compatible IEEE 802.11a/b/g PC card or device for each computer that you wish to
wirelessly connect to your wireless network;
yAccess to one laptop or PC with an Ethernet card and cable that can be used to complete the
initial configuration of the unit;
yA Web browser program, such as Microsoft Internet Explorer 5.5 or later, or Netscape 6.2 or
later, installed on the PC or laptop you will be using to configure the Access Point
yTCP/IP Protocol (usually comes installed on any Windows PC)
The WH-9100MESH operates with Power over Ethernet (PoE) which requires the installation of a
separate power injector which “injects” DC current into the CAT5 cable (including in package).
2.2 Site Survey
The WH-9100MESH requires physical mounting and installation on the site, following a prescribed
placement design to ensure optimum operation.
2.2.1 Estimate Bridge Transmit Distance
Normally, the bridge need transmit RF signal to another bridge device at long distance. You may be
able to use below equation to calculate the RF link Budget.
Fade Margin = received signal – receiver threshold
Where
Received signal = Transmitter power – Transmitter cable loss + Transmitter antenna gain – free
space path loss + Receiver antenna gain – Receiver cable loss
Received threshold = Received sensitivity
yFree Space Path Loss

Using below Free Space Loss Formula to calculate free space path loss
DFLP1010 log20log206.96 ++=
Where
LP= free space path loss between antennas
F = frequency in GHz
D = path length in miles
2.2.2 Estimation Bridge’s antenna Location
When as bridge device, the WH-9100MESH may need to be mounted outdoors on a high place to
achieve the best bridge result. The Fresnel zone and Earth bulge dominate to decide how high that
the unit’s Antenna need be put. The total antenna height equals the width of Fresnel zone plus the
height of earth bulge.
yFresnel zone:
The Fresnel zone is the area around the visual
line-of-sight that radio waves spread out into
after they leave the antenna. This area must be
clear or else signal strength will weaken. The
rule of thumb is that 60% of the Fresnel zone
must be clear of obstacles. Typically, 20%
Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage, signal loss will
become significant. The equation of the width of Fresnel Zone is

Where
W = Width of the Fresnel Zone (in feet)
D = Distance between the antennas (in miles)
F = Frequency in GHz
yEarth Bulge
When the transmit distance of RF signal is longer than seven miles, the curvature of the earth may be a
factor and require the antenna put at higher location. The additional antenna height can be calculated
by below formula:

2.3 Cabling
The following figure illustration shows the external cable connectors on the WH-9100MESH. The WAN

port is used to connect the WH-9100MESH to the organization’s LAN. The Ethernet cable is run from
the WH-9100MESH WAN port
to the Power Injector which is
then connected to a power
source and wired LAN. A
second (LAN port) Ethernet
RJ45 connector is designed
for use during initial
configuration and as LAN
function when set up as
Gateway mode
This uses an RJ45 cable to
connect the WH-9100MESH
to a laptop. The following
diagram demonstrates the
setup.
2.4 Antenna Installation
2.4.1 Antenna for AP
The package includes two 5dBi omni-directional antennas and two antenna connectors at
WH-9100MESH’s real panel are used for AP to support diversity function. Thus, for getting best
performance, those two antenna connectors need plug with antennas. Don’t let antenna connectors are
open when unit is working, or you need to enter configuration screen to set the Tx Pwr Mode as Off at
Wireless Access Point –General. Some experience show us and we want to suggest that the
equipment may need to up side down while the it is put at high location. For the case where the AP is
placed high on a tower, the part of the antenna pattern is pointed towards the sky instead of the ground
where the clients are. Hence if you are standing underneath the antenna, you may not get much of a
signal.
2.4.2 Antenna for Bridge
The antenna connector at front panel is used for bridge. To get the best performance, the bridge’s
antenna should far away AP’s antenna. Using 1.5m low loss antenna cable connects to this connector
then connects a directional antenna at the other end of cable. Since the Bridge’s antenna is directional
antenna normally; it should be toward to another WH-9100MESH Bridge unit’s antenna directly.
Anything in the line of sight between on antenna at the other can cause major issue for RF link. You can
exploit the SS LED or enter configuration screen Wireless Bridge –General to understand received
radio signal strength and make sure the Bridge antennas are installing well.
To comply with FCC RF exposure compliance requirements, the antennas used with the
WH-9100MESH must be installs with a minimum separation distance of 20 cm from all people and must

not to be co-located or operated in conjunction with any other antenna or transmitter. Installation should
be accomplished using the authorized antenna and/or cable provided with the device or available form
the manufacturer/distributor for use with this device. Changes or modifications not expressly approved
by manufacture or party responsible for this FCC compliance could void the user’s authority to operate
the equipment.
2.4.3 Sealing Antenna Connections
Once all antennas have been installed, the connection should be sealed to protect them in an exterior
harsh environment using a self amalgamating polyisobutylene tape which, over a period of hours,
adheres to itself and forms a single amalgamated rubber molding conforming to the shape of the item it
is covering. Once the tape is in place for several hours, it forms a shaped rubber molding that is
resistant to water and most solvents. It remains stable over a wide temperature range and degrades
very slowly in sunlight. Be sure that it is completely dry when applied. If you need to uninstall it after it
has sealed for 30 minutes or more, cut it away with a sharp knife.
2.4.4 Lightning Arrestor Installation
The potential for lightning damage should always be considered when setup this machine at outdoor
environment. A variety of lightning protections are available. Make sure the equipment is properly
grounded to provide low-impedance paths for lightning currents and using the lightning arrestor to
protect antennas. You can contact OvisLink to buy Lightning Arrestor and follow Appendix B to install
lightning arrestor.
