Introduction
Welcome to wireless networking. You have
purchased RadioLAN’s Model 140 MOBILINK, a
wireless network device that allows you to connect
a PC that uses a PCMCIA slot to a RadioLAN
wireless network. RadioLAN wireless networks
allow network stations to access shared network
resources using a full-speed 10Mbps connection,
without typical cabling requirements.
Using the Model 140 MOBILINK in a notebook PC,
you can easily move from one location to another
without searching for a network port. If your
notebook is powered on and placed upon a rolling
cart, you can route through the workplace while
taking notes or performing data entry. One example
of this type of user would be a medical professional
Figure 1: The Model 140 MOBILINK
that regularly dispenses medication to a number of
patients. While operating on battery power, the
nurse moves from one room to the next. While using the Model 140 MOBILINK, the nurse’s station
maintains a wireless connection to the facility’s network, and can continually receive network
messages, e-mail, and chat requests throughout the day.

Another example of Model 140 use would be a professional in an office complex. When using a hardwired network, the professional would typically have connection to the network in his office, but would
leave this connection to valuable resources behind when going to meetings in conference rooms.
When using the Model 140 MOBILINK, the professional would have network resource access while in
his office, and during meetings in conference rooms. The professional would enjoy necessary
network resources any time they were required.
The Model 140 MOBILINK comes with RadioNET Manager, RadioLAN’s powerful network connection
application. RadioNET Manager manages wireless network stations, enabling them to function at
optimum speeds and performance.
With RadioNET Manager you can gain access to shared network resources like printers, hard disk
drives, and other network stations. You can also receive network performance information that allows
you to:
•
•
•
•
•
•
•
View detailed information for a selected station.
View information about several stations at once.
Modify your station name.
Modify station Subnet ID.
Identify access type for each station.
Test individual stations to determine success/failure rate of transmissions.
Test the communication connection between stations.

Inserting and removing the MOBILINK
The transceiver comes installed on the end of the PCMCIA card, and is hinged for easy installation
and safe storage after removal. The unit is designed to open at a 130-degree angle from the PCMCIA
card. This allows the card to slide completely into the PCMCIA slot inside of the PC.
When using other PCMCIA devices: When the unit is open, the MOBILINK’s antenna points
upward. If you use other PCMCIA devices in a second slot, consider inserting the MOBILINK into the
top slot. This allows cable access to other the other card because the MOBILINK’s antenna does not
cover the other card.
The PC card interfaces the transceiver with your personal computer. It slides into any Type II or Type
III PCMCIA slot inside your notebook. After properly installing the MOBILINK, and software drivers,
you will configure the unit using RadioNET Manager.

Range of Operation
RadioLAN networks provide a radio carrier range of 250 feet
with a nominal data range of a 120 feet radius from each
station. Your system’s range may be greater than 120 feet
depending upon the environment. Within the data range, a
station can exchange information at full Ethernet speeds.
120 feet
data range
For best operation, RadioLAN recommends that you locate
all stations within a 120-foot circular area (see Figure 11).
This ensures proper operation of the network’s CSMA/CA
feature, which overcomes network communication
collisions.
Obstructions can decrease the data range: RadioLAN is
designed to operate in a semi-open office environment.
Listed below are some obstructions that may reduce your
data range:
•
•
•
•
•
Walls made of a metallic substance
Thick concrete walls
Walls reinforced with metallic studs
Foil-backed insulation installed within walls
Desktop objects that surround your RadioLAN transceiver

Roaming
Two Radio Carrier Areas
RadioLAN networks provide an automatic
ability in the client stations to select the
Access Point with the best signal. This allows
the client stations to move from one Access
Point to another without user intervention.
For instance, a portable computer using the
RadioLAN Model 140 card may easily move
from one area of the building to another area
served by a separate Access Point, while
receiving 10Mb service. This allows the user
to take the computer from the office area, to a
conference room and continue to work on the
network.

The client stations software manages the
relationship to the nearest access point, and
Figure 12: Roaming Between Access Points
when conditions change, the client station will
notify the new Access Point that it is selected
to provide service for that client, and the old Access Point to discontinue service. This is performed
automatically and seamlessly.

Performing a Site Survey
Performing a site survey allows you to map out your signal quality ratings throughout the office area.
To perform the survey, you need to configure two stations. For example, the first station might be a
desktop station. The second station might be a wireless notebook station using the Model 140
PCMCIA Card. While testing, each station is monitoring the other for connectivity quality.
Maping the Site
Create a map of the wireless site. On the map, mark the locations of each stationary station, for
example, mark each office where a wireless station will be located. Also specify and mark the station
that will connect to the hard-wired 10BaseT local area network. In this example, the Access Point is
the center point of the wireless network.
From the Access Point, measure the distance to each office where a wireless station is located. Note
the distance at each station on the map.
Performing the Test
1.
Using RadioNET Manager, view the NETWORK INFORMATION AND CONNECTIVITY screen at both
stations to monitor the connectivity quality of the other station.
2.
Raise and locate the desktop Access Point station’s transceiver to the highest possible location,
clear from obstructions on any side.
890-013 06/02/99 Version 1

3.
With the portable notebook station, move to the location where each wireless station will be
located. Locate the notebook so that you can position its transceiver as close to the location
where the proposed station’s transmitter will be located. Place the transceiver, and then call up
the NETWORK INFORMATION AND CONNECTIVITY screen onto the notebook’s screen. Read the
rating for the Access Point. If the Access Point does not have a rating of 5, attempt to raise the
value to 5 by relocating the transceiver. Note the highest rating that you attain during the test on
the map. Also note that this rating was noted at the notebook’s location.
4.
With map in hand, go to the Access Point, and then read the connectivity rating for the notebook
on the NETWORK INFORMATION AND CONNECTIVITY screen. Note this rating on the map at the
location of the notebook. Also note that this reading was taken from the Access Point.
After noting the two ratings, move to the next designated station location. Repeat the steps above
until you note each location’s connectivity quality rating from the Access Point and the notebook.
When you have completed your mapping, you will have an illustrated view of the best connectivity
quality that can be attained between the Access Point and each station in the network. You will also
be familiar with the best locations to position transceivers throughout the network.
