AirLive WH-9000MESH - Manual (Page 12)

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-9000MESH is designed to be attached to the wall at appropriate locations. To complete
the configuration, you should have at least the following components:
y PCs with one of the following operation systems installed: Windows NT 4.0, Windows 2000 or
Windows XP;
y A compatible IEEE 802.11a/b/g PC card or device for each computer that you wish to
wirelessly connect to your wireless network;
y Access to one laptop or PC with an Ethernet card and cable that can be used to complete the
initial configuration of the unit;
y A 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
y TCP/IP Protocol (usually comes installed on any Windows PC)
The WH-9000MESH 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-9000MESH 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
y Free Space Path Loss
