Introduction
Congratulations on choosing one of NDC’s InstantWave High Rate wireless
networking product’s family. InstantWave High Rate was one of the first IEEE
802.11b wireless standard compliant products in the industry and was designed to
maximize the convenience of networking. You will find InstantWave High Rate
products very easy to setup and use.
The User’s Guide gives comprehensive instructions on installing and using the
InstantWave High Rate Access Point (AP). The AP provides a transparent bridged
connection between a wired network and a wireless network and allows your
wireless stations to communicate with devices attached to your wired network. It
manages the flow of data packets from the wired LAN to the wireless LAN, and
vice versa.

Glossary
Group ID/BSSID
A Group ID (the 802.11 standard uses the term BSSID) is the ID of a wireless cell.
A wireless cell is usually made up of stations in an area that the radio signal can
comfortably cover. In other words, any wireless station in the cell can
communicate with any other within reach of the radio signal.
Domain Name/ESSID
A “Domain” is most commonly used to refer to a group of computers whose
hostnames share a common suffix. The domain is usually defined by the network
administrator as a segment/subnet of a large network and may be made up of
overlapping wireless cells. Wireless nodes can roam freely within the same
domain without disconnecting from the network.
Roaming
The convenience of a mobile PC is the ability to move freely. The concept is
similar to that of a cellular phone moving from one base station to another.
InstantWave High Rate offers built-in high performance and seamless roaming
capabilities.
Regulatory Domain
InstantWave High Rate products use the unlicensed ISM (Industrial, Scientific,
Medical) band to communicate through radio waves. Different countries offer
different radio frequencies to be used as the ISM band. There are four frequency
bands defined by 802.11: Japan (2.471GHz – 2.497 GHz), USA, Extended Japan,
Canada, and Europe (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz),
and France (2.4465 GHz – 2.4835 GHz). To use InstantWave High Rate in a
country not listed above, check with your government’s regulating body to find the
correct frequency band to use. All InstantWave High Rate products are supplied
preset to the country of sale’s frequency band.
2 InstantWave High Rate Access Point
InstantWave High Rate is extremely versatile in providing varying levels of
network management. For Small Office/Home Office users, setup and
Installation section, on page 9, provides simple instructions to get your network up
and running within minutes. Go to the Access Point Hardware Installation section
if your network will meet the following criteria:
•
•
You will accept all default values
Your network will have only one Access Point
The AP COMFig Tool, see page 12, permits AP configuration from a PC via a
COM port connection. The program enables the user to change the default Access
Point IP configuration settings before introducing a new AP to an already
established wireless network.
Before using the setup tool, you should read through the next section “Planning
Your Network”, in order to get the best possible performance from your
InstantWave High Rate wireless network.

Planning Your Network
Infrastructure Network Types
An Infrastructure network is formed by several stations and one or more Access
Points (APs), with the stations within a set distance from the AP. Figure 1 depicts
a typical Infrastructure network topology.
There are three infrastructure network setups that are commonly used. It is a good
idea to understand the possible network setups and configuration requirements
before planning your wireless network.
Type 1.
The simplest wireless infrastructure network is composed of one
Access Point (AP) and a few wireless Stations communicating via
radio waves (Figure 1). This setup enables mobile stations to
communicate with each other. The main benefit of this type of
network is to extend the range of the network. If an AP is placed
between Station-1 and Station-2, the radio transmission distance is
AP. The drawback of this configuration is that the effective
bandwidth is halved since all communication is relayed by the AP.
Figure 1. Simple Wireless Infrastructure Network
Type 2.
The next simplest wireless network is very similar to the Type 1
network. This time the AP is connected to a wired Ethernet network
as a node. In this configuration the AP is effectively performing as a
bridge between the wired Ethernet and the wireless networks (Figure
2).
Wireless users have the same access to the network resources as they
would have if they were wired. This type of network is usually used
to extend an existing network into a difficult to wire or a roaming
environment.
4 InstantWave High Rate Access Point
Server
Figure 2. AP to Wired Ethernet Bridge
Type 3.
The third type of network is composed of multiple APs and multiple
Stations (Figure 3). The APs could also be connected to servers on
the wired Ethernet network. The shadowed area represents signal
overlap between subnet1 (AP-1) and subnet2 (AP-3).
Figure 3. Multiple AP Network
The reasons for having multiple APs installed are:
1. To increase bandwidth in order to boost overall network performance
2. To extend the coverage range
Any other type of configuration is usually a mix of these commonly used types.

Planning an Infrastructure Network
This section explains some of the things you need to consider in planning an
Infrastructure network. Setting up is a two step process.
1. Install and configure the InstantWave High Rate products
2. Decide the best physical location of the InstantWave High Rate products so as
to optimize performance
into detail, the network planner should first decide whether to have a single AP
wireless network or a multiple APs network.
Single AP Installation
If you are setting up a simple network with only one AP and a few Stations (a Type
1 or Type 2 network configuration as described in Infrastructure Network, page 4),
the installation can be performed painlessly. All you need to do is make sure the
AP and all the wireless Stations hold the same “Domain Name” in their
configuration.
Adding a new Station to an existing Infrastructure Network is easy. Again, all you
need to do is to set the newly added Station’s “Domain Name” to the same as that
of the AP’s.
Multiple AP Installation
Install multiple APs in the same network (or Domain) with an overlapping signal
(Figure 3)
•
•
Use the same Domain Name
Enable the roaming function in the Station if roaming is required
Note: A Station will automatically connect to whichever AP in the same domain is
offering the best signal
6 InstantWave High Rate Access Point
Roaming
InstantWave High Rate products are equipped with seamless roaming capabilities.
Roaming is necessary to prevent mobile Stations from being disconnected from the
network as they move around.
InstantWave High Rate is designed to allow wireless Stations to roam freely within
an infrastructure domain composed of multiple APs with overlapping signal
coverage (as in the Type-3 network configuration described in the previous
section). For example, roaming enables Station-1 to move from the AP-1 signal
coverage area to the AP-2 signal coverage area without disconnecting from the
network. The handover is achieved transparently; the Station-1 user would not
realize he had moved from AP-1 to AP-2.
The requirements for a roaming environment are:
Installation, page 6)
COMFig Service, page13)
c) The mobile Stations must have the same Domain name as that of the APs
d) *It is advisable that APs on different TCP/IP subnets be given different
Domain names to avoid roaming confusion (seeAP COMFig Service ,
page13)
Note: If you want to move your mobile PC between different APs without
terminating the existing networking link, you need to enable the roaming
function on the Mobile Station. The APs that a Mobile Station will roam to
must also be configured with the same domain name. If a Station detects
that the signal quality with the current linked AP is weak, it will search for
an AP in the same domain with a better signal quality and automatically
establish a new connection with it. When a Station is roaming, it will
always use the same IP address. The TCP/IP router will not route
information packets to a Mobile Station if it re-associates with a AP that is
in a different TCP/IP subnet. In other words, if your network consists of two
subnets connected by a router, a Mobile Station may roam to a different
subnet with the same domain name and then fail to communicate with other
network devices via TCP/IP. To avoid running into such an awkward
situation, you must assign different domain names to different TCP/IP
subnets.

Access Point Placement Guidelines
A characteristic of radio communication is the “interference” problem. Radio is
receptive to interference. Therefore, the more interference you can avoid, the
better performance you will get from wireless products. The following section
describes how the InstantWave High Rate AP should be placed to reduce possible
interference.
A few tips to mention that are particularly significant in a radio wave
communications system:
1. Radio waves reflect or refract from buildings, walls, metal furniture, or other
objects. This could result in performance degradation due to the fluctuation of
the received signal.
2. Microwave ovens use the 2.45 GHz frequency band. InstantWave High Rate
also functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the
band with microwave ovens. This means that when a nearby microwave oven
is in use, it may interfere with InstantWave High Rate, resulting in
performance degradation on the wireless network.
Placing For Performance
For the best performance, it is advisable that users follow the guidelines below in
placing the product:
•
•
Place the AP as high as possible, in as open an area as possible
Avoid placing the AP (especially the antenna) close to metal objects (e.g., file
cabinets, metal cubicles, etc.)
•
Keep APs and Stations as far away as possible from microwave ovens (10
meters min. is advisable)
Placement Tools
InstantWave High Rate includes a Station utility program to help users find the
best location in which to place the AP relative to the location of the Stations.
1. Start the AP
2. Allow a wireless Station to connect with the AP
3. From the Station, run the InstantWave High Rate Station Monitor RF Signal
Quality Program
4. Move the AP and the AP’s antenna to find the best signal quality
Mounting the AP
The AP may be either freestanding or wall-mounted. Screws and a paper template
are provided for easy installation.

Encryption
Click the Encryption tab to setup the security options (Figure 9). This page allows
you to create up to four data encryption keys and enable encryption to keep your
data secure.
InstantWave High Rate Access Point 15
Figure 9. Encryption
Click the arrow to the right of the Method field. The pull-down method lists four
options:
Disabled (default)
The station communicates with this Access Point without any data encryption.
40 bit WEP
Allows station to communicate with this Access Point through 40 bit WEP key
data encryption.
128 bit WEP
Allows station to communicate with this Access Point through 128 bit WEP key
data encryption.
Proprietary
The station communicates with this Access Point through NDC proprietary data
encryption.
You must set the security keys before you enable use of encryption.
WEP stands for Wired Equivalent Privacy. It is an encryption scheme that
provides secure wireless data communications to users. WEP uses a 40-bit or 128-
bit key to control network access. In order to decode the data transmission, each
wireless client on the network must use identical keys.
Key Generation - There are two ways to generating a security key.
16 InstantDWowanvloeaHd ifrgohm WRwawte.SAomccaensusaPlso.cionmt . All Manuals Search And Download.
The first is by entering any text in the Passphrase field. Click the Generate button.

from the dropdown list of the Default Key box. If you do not select a key, key 1 is
selected, as it is the default key. Click Apply.
Another key generation method is to insert key values directly into the key fields
using a keyboard. Select the Key number in the Default Key box. If the Key is not
entered correctly, a client cannot access the wireless LAN resources. Click Apply
Filter:
The next tab on the dialog box is Filter (Figure 10). This is a one-way protocol
filtering mechanism that prevents the AP from transmitting certain protocols from
the Wired Ethernet LAN into the Wireless zone. If you do not require particular
protocols on the wireless part of your network you can save bandwidth by enabling
the protocol filter.
