Download from Www.Somanuals.com. All Manuals Search And Download.
•
InstantWave Access Point (AP): This product provides a
transparent bridged connection between a wired network and a
wireless network and allows Wi-Fi compliant wireless stations to
communicate with devices attached to a wired network. Not only
does it support wireless stations with wireless LAN adapters, such as
PC cards, PCI adapters, and USB adapters, but it also operates
together with the NWH6210 Wireless Ethernet Bridge.
•
NWH6210 Wireless Workgroup Bridge (WWB): This is a
workgroup bridge that supports 16 Ethernet devices via an Ethernet
Hub or Switch. The NWH6210 can only work together with an
InstantWave Access Point under InstantWave’s proprietary bridge
protocol. It is very useful in conference rooms, hotels, etc. to
connect wireless devices to the wired LAN environment.
•
NWH2610 Wireless Ethernet Client (WEC): The WEC is an
Ethernet client that supports a single Ethernet device. The
NWH2610 can only work together with an InstantWave AP under
InstantWave’s proprietary bridge protocol. It is very useful in
public places, hotel rooms, coffee shops etc. where temporary
connection to a local LAN or the Internet is required.
• IWMS (InstantWave Management System): This is a powerful
Network Management System that is fully compatible with the
industry standard SNMP (Simple Network Management Protocol). It
features:

including Multi-Monitor, Batch-Upgrade, Batch-Reset, and
Bathc-LoadDefault. Batch mode operation is useful when
deploying multiple InstantWave products
Friendly user interface with a consistent look and feel
Automatic Discovery of InstantWave Products
A powerful automatic-discovery algorithm is built into the InstantWave Network
Management System. With a simple click on the “Discovery” icon, all
InstantWave APs, WWBs, and WECs within the subnet will be discovered. This
discovery feature is based on the following techniques:
•
DHCP Client and IP recovery: InstantWave APs, WWBs, and
WECs have a built-in DHCP client and will request an IP address
from a DHCP server so that SNMP (Simple Network Management
Protocol) can be further applied. Should there be a failure of the
DHCP server; when it recovers, the AP, WWB, and WEC will
automatically negotiate for a new IP address
•
Auto-IP: When the AP, WWB, or WEC cannot get an IP address
from a DHCP server, they will auto-assign an IP address of
169.254.x.x , and a subnet mask of 255.255.0.0.
A Windows OS PC originally configured as a DHCP client will
follow the same algorithm to assign itself an IP address in the same
subnet. Users may need to renew the IP settings (see the following
section), otherwise Windows may continue to use the previous IP
address instead of executing the Auto-IP procedure

Terminology Used in this Guide
BSSID/MAC ID
BSSID (Basic Service Set ID) is an ID unique to each InstantWave product. It is
factory set and is identical to the MAC ID (Media Access Control ID). It allows
each InstantWave product to be identified on the network.
Domain Name/SSID
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 concept is similar to that of a cellular phone moving from one base station
(one AP) to another. InstantWave offers built-in high performance seamless
roaming capabilities.
Regulatory Domain
InstantWave 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 IEEE 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 in a country not listed above,
check with your government’s regulating body to find the correct frequency band
to use. All InstantWave products are supplied preset to the country of sale’s
frequency band.

WEP
WEP stands for Wired Equivalent Privacy. It is an encryption scheme that
provides secure wireless data communication. WEP uses a 40-bit or 128-bit key
to encrypt data. In order to decode the data transmission, each wireless client on
the network must use identical keys.

How to Use this Guide
The User’s Guide gives complete instructions for installation and use of the
InstantWave Access Point (AP), Wireless Workgroup Bridge (WWB) and Wireless
Ethernet Client (WEC). All of them share a common user interface. The major
difference among them is:
•
•
The AP has MAC address access control of the wireless stations
The WWB‘s supports up to 16 Ethernet devices. An access table is
provided by the WWB to allow 16 Ethernet devices’ MAC addresses
to be registered.
•
The WEC supports one Ethernet attached device.
InstantWave products are supplied with factory set default network settings. Use
the IWMS tool to change the default settings before introducing a new device to an
already-established wireless network.
The IWMS program is a simple-to-use, yet extremely powerful, SNMP-based
utility for online central configuration and network management from a remote
station on the same subnet. A trap management program is also provided to
monitor/diagnose InstantWave products.

Plan the Network
Infrastructure Network Types
An infrastructure network is formed by several stations (WWBs or WECs) and one
or more Access Points (APs), with the stations (WWB or WEC) 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 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 the stations, the radio
transmission distance is effectively doubled since Wireless
Computer-1 can talk to Wireless Computer-2 through the AP. The
drawback of this configuration is that the effective bandwidth is
halved since all communication is relayed by the AP.

network. This time the AP is connected to a wired Ethernet network
as a node. In this configuration the AP operates as a bridge between
the wired Ethernet network 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.

Any other type of configuration is usually a mix of these commonly used types.
Planning WWB and WEC for your wireless network
The InstantWave WWB may be used together with a hub or switch, and wirelessly
associates to the existing network backbone via InstantWave APs. It can connect
up to 16 users (per bridge) for temporary meeting areas, classrooms, etc.
The InstantWave WEC needs no extra drivers or wireless LAN configuration for
wireless operation. It may be connected to most Ethernet-ready equipment, such
as industrial PCs, scanners, etc.
Figure 4, on page 20, illustrates a complex infrastructure network that combines
APs, WWBs, and WECs.

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 products
2. Decide the best physical location of the InstantWave products so as to
optimize performance
The following section gives quick guidelines for these two steps. First, decide
whether to have a single AP wireless network or a multiple AP network.
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 Types,
page 17), all you need to do is make sure the AP and all the wireless stations hold
the same ‘Domain Name’ (SSID) & Security (WEP) setting 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’ (SSID) & Security
(WEP) setting 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, page 19)
•
•
Use the same Domain Name (SSID) & security (WEP) settings
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 allows 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 21)
b) The APs must be configured to have the same Domain name (SSID) &
security (WEP) setting (see Filter, page 33)
c) The mobile stations must have the same domain name (SSID) & security
settings (WEP) as those of the APs
It is advisable that APs on different TCP/IP subnets be given different domain
names to avoid roaming confusion (see the note below).
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 station. The APs that a mobile station will roam to must 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 associates with an 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.

Using the InstantWave Management
System
Once the WWB (or WEC) is connected to an Ethernet network, a network
administrator can connect to it from any PC on the same network via the
InstantWave Management System (IWMS) utility.
The IWMS utility is a Windows-based SNMP management tool, allowing network
administrators to remotely configure and monitor the WWB (or WEC) through
both an Ethernet and a wireless connection. To launch the IWMS utility:

Note: A WWB (or WEC) will directly transfer SNMP respond packets
(confirmation packets) to an IWMS PC if it is within the same LAN (the
same subnet mask). If an SNMP respond packet from a WWB (or WEC) is
destined for an IWMS PC on another LAN, then the SNMP respond packet
needs to go through a router-gateway. The default gateway is the path to
that router. If you set the correct default gateway, then you can use an
IWMS manager (i.e. a PC running IWMS) physically located in a different
subnet to manage this WWB (or WEC).
If you wish to change the defaults, set each WWB (or WEC) to its new IP address
before introducing it to the open network. All WWBs (or WECs) within the same
network must have the same TCP/IP subnet address.

table from a network disk for ease of access). Once the Host Table has been
imported, the IWMS will automatically check the availability of WWBs or WECs
listed on the Host Table. This is an extremely powerful feature as Auto-Discovery
can only find InstantWave’s devices when they are alive. A failed device will not
be found via Auto-Discovery. The devices listed in the Host Table should be
available and provide a service. If they do not exist, the IWMS can report their
absence immediately so that the system administrator can take immediate action.
New/Edit/Delete a Host Address on the Host Table
Click the Add New Address button to open the New/Edit Address dialog box
(Figure 33). You only need enter an IP address; the IWMS will automatically
find WWB and WEC hardware address and device types.

Hardware
InstantWave Product Placement Guidelines
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 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 signals, resulting in performance
degradation on the wireless network.
For the best performance, follow the guidelines below in placing the product:
•
•
Place as high as possible, in as open an area as possible
Avoid placing the WWB or WEC (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)
Mounting the WWB
The WEB may be either freestanding or wall-mounted. Screws and a template
are provided for easy installation. The installation procedures to fix the WWB to
a wall are as below:
