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.  
InstantWave High Rate Family  
The InstantWave High Rate Access Point is part of a family of easy to use high  
performance wireless communication products. The family products include:  
InstantWave High Rate Access Point (NWH660, NWH650)  
InstantWave High Rate PCI Card (NWH630)  
InstantWave High Rate PC Card (NWH610)  
System Requirements  
System requirements to install and operate the InstantWave High Rate Access  
Point are:  
A RS-232 cable  
An Ethernet drop (UTP)  
A PC (only used when configuration of the AP’s Network properties is  
necessary)  
Cabling  
Connecting the AP to an Ethernet network requires an Unshielded Twisted-Pair  
cable. The AP fits into the network just as any other node would do. An LED will  
light to indicate a connection. The cable length should follow Ethernet standards  
in each case.

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.

InstantWave High Rate is extremely versatile in providing varying levels of  
network management. For Small Office/Home Office users, setup and  
configuration is a quick, four-step process. The Access Point Hardware  
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  
effectively doubled since Station-1 can talk to Station-2 through the  
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.

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  
The following sections give quick guidelines for these two steps. Before we go  
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

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:  
a) Multiple APs with overlapping signal coverage (see Multiple AP  
Installation, page 6)  
b) The APs must be configured to have the same Domain name (see AP  
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.

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.
