FCC Notice
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
•Consult the dealer or an experienced radio / TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications to this equipment. Such modifications could void the user’s authority to operate
the equipment.

1 Installation Considerations
The AP lets you access your network, using a wireless connection, from virtually anywhere
within its operating range. Keep in mind, however, that the number, thickness and location of
walls, ceilings, or other objects that the wireless signals must pass through, may limit the range.
Typical ranges vary depending on the types of materials and background RF (radio frequency)
noise in your home or business. The key to maximizing wireless range is to follow these basic
guidelines:
zKeep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate RF noise.
zKeep the number of walls and ceilings between the AP and other network devices to a
minimum - each wall or ceiling can reduce your AP’s range from 3-90 feet (1-30 meters.)
Position your devices so that the number of walls or ceilings is minimized.
zBe aware of the direct line between network devices. A wall that is 1.5 feet thick(0.5
meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree
angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel
straight through a wall or ceiling (instead of at an angle) for better reception.
zBuilding materials can impede the wireless signal - a solid metal door or aluminum studs
may have a negative effect on range. Try to position wireless devices and computers with
wireless adapters so that the signal passes through drywall or open doorways and not
other materials.

1.1 Network Topology – Access Point Mode
The diagram above is shown with an AirEther AB54E combined with external wide radiation
pattern antenna ( i.e. AirEther OA12 or AirEther SA1218 sector antenna). This setup can
achieve point to multipoint expanded wide area coverage . For cost effective sectorized mobile
or fixed wireless coverage area, use the AirEther AB54 with integrated 12 dBi antenna.

1.2 Network Topology – Repeater Mode
The AirEther AB54 or AB54E in the repeater mode extends AB54 series equipment and other
802.11 b/g Access Point’s coverage area to service hard to reach wireless clients. This is
convenient if a wired distribution system is not feasible. To retian the quality of service and
broadband internet experience of the wireless coverage area, do not extend a repeater system
beyond 2 to 3 hops. The table reference below indicates few manufacturer’s access point
compatibility uncertainty due to propriety. It is recommended to use AB54 series AP to ensure
full compatibility.
Make P/N 802.11 Chipset Compatible
Broadcom BCM94704-GAP b/g Broadcom Yes
Cisco 1231G b/g No
Conexant ISL3900A a/b/g Conexant No
D-Link DWL-2100AP b/g Atheros No
Linksys WAP54G b/g Broadcom Yes
Proxim AP600 b/g Atheros No

1.3 Network Topology – Wireless Bridge Point to Multi-Point Mode
The AirEther AB54 or AB54E in the wireless bridge mode provides two functionality, point to
point or point to multipoint layer 2 bridge. Each AB54 has packet fowarding capability to
provide AP to AP communication. Inscape Data bridges may span across multiple hops to span
across buildings, campus, and cities. For high capacity bridge, please see the AirEther BR108
for optimal backhaul performance up to 108mbps data rate.
The X mark on the above topology diagram is an example of what not to do
using the bridge mode. Creating a bridge loop will cause instability in the bridge
system.

Attention:
zThe cable distance between the AB54/E and the Router, Switch, or PC should not exceed 100
meters, the Ethernet cable limitation.
zIn 10Mbps operation, Cate

ory 3/4/5 cable can be used for the cable connection. To reliably
operate your network at 100Mbps, you must use Category 5, or better data grade cables.
