INTRODUCTION
All ParkerVision Wireless products are designed
and manufactured by ParkerVision. Products are
fully compliant with IEEE 802.11b standards and are
optimized to provide maximum possible speed and
bandwidth through your Internet connection for fastest
uploads and downloads.
The distance capabilities of your wireless network
equipment directly affect your signal quality. Distance
capabilities are usually stated in terms of outdoor, open
fi eld reach. However, this reach is greatly diminished
indoors by walls, doors, construction techniques and
appliances that may block the radio signal. A wireless
network adapter that tests outdoors at 200 feet could, in
an indoor environment, provide 20 feet in one direction
and as little as 5 or 10 feet in another direction. Factors
such as building materials, fl oor plans and furnishings
can greatly impact the signal range, quality and rate of
data transmission. The extent to which your signal is
affected varies greatly depending on your environment.
Wireless network products powered by D2D technology
will provide better performance than other products
because they can achieve open fi eld distances of up
to one mile, (when a D2D enabled adapter is used in
conjunction with a D2D enabled base station). The D2D
adapter alone provides 3 to 7 times the distance of other
leading brands. This is suffi cient to reach all rooms in
most homes or small offi ces.

4.6 MORE ON AD-HOC AND AP MODES
Ad-Hoc Mode (Peer-to-Peer Workgroup)
The Institute of Electrical and Electronics Engineers (IEEE) standard for wireless LAN’s (WLAN’s),
802.11 offers two methods for confi guring a wireless network — Ad-Hoc and infrastructure (Access
Point). In an Ad-Hoc network, computers are brought together as needed. In this instance, there
are no fi xed points to the network — each node can generally communicate with any other node.
There is no Access Point involved in this confi guration. This enables the set up and use of a small
wireless workgroup and allows workgroup members to exchange data or share printers as supported
by Microsoft Networking in the various Windows operating systems. To set up an Ad-Hoc workgroup
operating with standard protocols:
• Set all stations to connect in Ad-Hoc mode (or Peer-to-Peer workgroup mode).
• Set all stations to use the same network name (or SSID).
• Set all stations to use the same wireless channel for communication.
• Set all stations to either disable the WEP encryption key, or set all stations to use an identical WEP
encryption key.
AP Mode (Infrastructure Mode)
With a wireless Access Point (AP), you can put the ParkerVision-Wireless PC LAN into AP
(Infrastructure) mode. It provides wireless connectivity to multiple wireless network devices within a
fi xed range or area of coverage, interacting with a wireless node by way of an antenna. In AP Mode,
the wireless Access Point converts airwave data into wired Ethernet data, acting as a bridge between
the wired LAN and wireless clients. Connecting multiple Access Points via a wired Ethernet backbone
can further extend the wireless network coverage. As a mobile computing device moves out of the
range of one Access Point, it moves into the range of another. As a result, wireless clients can freely
roam from one Access Point domain to another and still maintain seamless network connection. To set
up an AP network operating with standard protocols, do the following:
• Set all wireless stations to connect in AP mode.
• Set all stations to use the same network name (or SSID).
• Set all wireless Access Points to use the same network name (or ESSID).
• Set all stations to disable the WEP encryption key, or set all stations to use an identical WEP
encryption key as used by the Access Point.
• Set up wireless channels used by individual Access Points. (It is not necessary to set channels on
the stations as the stations will automatically scan through all channels for the nearest Access Point.
• You should consult your access point documentation for the available options.
Page 21

2323
USB1500 Wireless PC LAN Adapter
4.7 MORE ON SSID
Service Set Identifi cation (SSID)
The Service Set Identifi cation (SSID) is a thirty-two alphanumeric character (maximum)
string identifying the wireless local area network. ParkerVision-Wireless refers to the SSID as
network name. For stations to communicate with each other, all stations must be confi gured
with the same SSID. A wireless LAN consisting of nodes operating in Ad-Hoc confi guration
without an Access Point is called a Basic Service Set (BSS). All nodes in a BSS must use the
same Basic Service Set ID (BSSID). In an AP (Access Point) confi guration, multiple BSS can
be confi gured to form an Extended Service Set (ESS). In this confi guration, the Access Points
are confi gured with the same Extended Service Set ID (ESSID). Wireless clients confi gured
with the same ESSID can freely roam from one Access Point domain to another and still
maintain a seamless connection to the network.
4.8 MORE ON WEP ENCRYPTION
Authentication and WEP Encryption
Wireless links are vulnerable to information theft. To provide a certain level of security,
IEEE 802.11 standard has defi ned two types of authentication methods, Open System and
Shared Key. Open System authentication is a null algorithm. Shared Key authentication is an
algorithm where both the transmitting node and the receiving node share an authentication
key to perform a checksum on the original message. By default, IEEE 802.11 wireless devices
operate in an open system network. Wired Equivalent Privacy (WEP) data encryption is
utilized when the wireless nodes or access points are confi gured to operate in Shared Key
authentication mode. ParkerVision-Wireless utilizes the following 802.11b solutions: the
standard based 64-bit WEP data encryption and 128-bit WEP data encryption. The 64-bit
WEP data encryption method allows for a fi ve-character (40 bits) KEY. Additionally, 24 factoryset bits are added to the 40-bit input to generate a 64-bit encryption key. (The 24 factory-set
bits are not user confi gurable.) This encryption key will be used to encrypt/decrypt all data
transmitted via the wireless interface. The 128-bit WEP data encryption method consists of
104 confi gurable bits. Similar to the 64-bit WEP data encryption method, the remaining 24 bits
are factory set and not user confi gurable.

LAN must be confi gured on the same radio channel. An Ad-hoc wireless LAN is available at a
departmental scale for a branch or SOHO operation.

Ad-hoc Wireless LAN Topology - Continued
The ParkerVision Wireless LAN Adapter provides access to a wired LAN for wireless computers.
An integrated wireless and wired LAN is called an Infrastructure confi guration. A group of
wireless LAN computer users and an Access Point constitute a Basic Service Set (BSS).
Each wireless-equipped computer in this BSS can talk to any computer in the wired LAN
infrastructure via the Access Point.
Infrastructure confi guration will extend the accessibility of a wireless station to the wired LAN.
Multiple Access Points will allow roaming and it will increase the transmission range. The
Access Point is also able to forward data within its BSS. The effective transmission range in
an Infrastructure LAN is doubled.
