iv Information for Canadian Users
Information for Canadian Users
The Industry Canada label identifies certified equipment. This certification means that the equipment meets
certain telecommunications network protective operation and safety requirements. The Industry Canada
does not guarantee that the equipment will operate to a user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities
of the local telecommunications company. The equipment must also be installed using an acceptable
method of connection. In some cases, the company's inside wiring associated with a single line individual
service may be extended by means of a certified connector assembly. The customer should be aware that
compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated
by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions,
may give the telecommunications company cause to request the user to disconnect the equipment.
For their own protection, users should ensure that the electrical ground connections of the power Navigator,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution
Users should not attempt to make such connections themselves, but should contact the appropriate
electrical inspection authority, or electrician, as appropriate.
Note
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus
set out in the radio interference regulations of Industry.
ZyAIR G-405 User’s Guide
FCC Statement v
Federal Communications Commission
(FCC) Interference Statement
The device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that may cause undesired
operations.
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 commercial environment. 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.
If this equipment does cause harmful interference to radio/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:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and the receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.
Notice 1
Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
Caution
1. To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm
must be maintained between the antenna of this device and all persons.
2. This Transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.

ZyAIR G-405 User’s Guide
Wireless LAN Network 2-1
Chapter 2
Wireless LAN Network
This chapter introduces the wireless LAN network technology.
2.1 About Wireless LAN Network
This section describes each wireless LAN parameter.
2.1.1 Channel
The range of radio frequencies used by IEEE 802.11 wireless devices is called a “channel”. The number of
available channels depends on your geographical area. You may have a choice of channels (for your
region) so adjacent APs (access points) should use different channels to reduce crosstalk. Crosstalk occurs
when radio signals from different access points overlap causing interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, the AP should be on a
channel at least five channels away from a channel that an adjacent AP is using. For example, if your
region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6
or 11.
2.1.2 SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network.
Wireless devices must have the same SSID to communicate with each other.
2.1.3 Transmission Rate
Your ZyAIR automatically adjusts the transmission rate to operate at the maximum transmission (data)
rate. When the communication quality drops below a certain level, the ZyAIR automatically switches to a
lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when
the communication quality improves again, the ZyAIR gradually increases the transmission (data) rate
again until it reaches the highest available transmission rate.
2.1.4 Wireless Network Application
Wireless LAN works in either of the two modes: ad-hoc and infrastructure.
To connect to a wired network within a coverage area using Access Points (APs), set the ZyAIR operation
mode to Infrastructure. An AP acts as a bridge between the wireless stations and the wired network. In
case you do not wish to connect to a wired network, but prefer to set up a small independent wireless
workgroup without an AP, use the Ad-hoc mode.
ZyAIR G-405 User’s Guide
2-2 Wireless LAN Network
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless clients communicate
directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service
Set (IBSS).
Figure 2-1 Ad-hoc Network Example
To set up an ad-hoc network, configure all wireless clients in ad-hoc network type
and use the same SSID and channel.
Infrastructure
When a number of wireless clients are connected using a single AP, you have a Basic Service Set (BSS).
Figure 2-2 BSS Example
A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set
(ESS) or infrastructure network. All communication is done through the AP, which relays data packets to
other wireless clients or devices connected to the wired network. Wireless clients can then access resource,
such as the printer, on the wired network.
