Radio Characteristics
The Telxon Mobile Node uses a radio modulation
technique known as spread spectrum transmission
(SST). This modulation technique provides high data
bandwidth and excellent immunity from interference
and multipath effects.
Two versions of the radio module are offered which
differ in their frequency band of operation:
o Air—I/O MN 900 900 MHz band (902 928 MH7.
range).
- Air-I/O MN 2.4 DS 2.4 GHZ band (2.400 2.485
CHz range).
Data is transmitted over a halfduplex radio channel
operating at data rates up to 860 kb/s (900 version)
and 2 Mb/s (2.4 D5 version),
Radio Ranges
The Telxon Mobile Node radio module is used in
indoor wireless radio networks. The radio range
achieved depends on the following:
- Data bit rates . better receiver gain at lower data
bit rates
Lower bit rate links have an advantage over higher
bit rate links. There is a decrease in receiver
threshold as the radio data rate increases. The
maximum radio range is achieved at the lowest
workable data bit rate.
. Antenna type and placement - increased range
with antenna height.
The key to maximizing range indoors is to place the
access point antenna above obstacles such as
cabinets. shelves, etc. An antenna mounted on the
ceiling provides excellent coverage,
0 Openness of the environment - open areas are
better than closed areas.
The less cluttered the work environment, the
greater the range.
0 Building materials -drywall vs concrete.
Floor-to—floor radio penetration depends on the
building materials used between floors. For
example. the range will be greater if the signal is
passing through drywall rather than concrete
blocks.
Table 1 provides a summary of typical radio ranges to
be expected for different situations.

Radio antenna
The Telxon Radio Node comes supplied with an
integrated dipole antenna and provides
omnidirectional (360 degree) coverage.
Security features
The Telxon Mobile Node provides secure and highly
reliable data communications by employing spread
spectrum technology, previously developed for
military "antijamming" and “low probability of
intercept" radio systems. Additional security is
l6
achieved through the use of a system identifier (SID).
The SID is a unique‘ 6 hexadecimal digit value that is
attached to each packet sent out over the radio. With
over 8 million possible SID settings, a high degree of
privacy and security can be assured. See Chapter X
for detailed information on setting the SID.
Radio network terminology
When configuring your system, and when reading this
document, keep in mind the following radio network
terminology:
Network tree
Conceptually. Telxnn‘s advanced radio local area
network is designed like an upsidedown tree‘ (see
Figure 2) with a root unit at the top, and repeaters
and radio nodes branching down and out from the
FOOL
Figure 2, Network tree
Wiud LAN
End mm
Root unit
An access point which is located at the tap ofa
network trees The root unit is the starting point in the
network and contains information in its registration
table regarding all nodes on the network.
Repeaters
A repeater is a wireless access point which is used to
extend the radio range of your network. A single
access point is limited to a specific RF range, lfyour
system configuration includes nodes outside this
range. you will need to add a repeater in order for
them to communicate.
Radio node
17
18
A PC, notebook computer‘ etc. containing a radio card,
End node
A radio node that is located at the end of the network
tree.
Parent/child node
Refers to the relationships between nodes on the
network tree. For example, the root unit (at the top of
the tree) would be the parent of the repeater and the
repeater would be the parent of the end nodes,
Conversely, the end nodes would be the children of
the repeater and the repeater would be the child of
the root unit.
Registration
Each access point (repeater or root unit) on the radio
network contains a registration table, used to control
the routing of packets from the Ethernet and the
radio network. The table controls the routing of
packets by maintaining entries for all radio nodes
situated below the access point on the Network tree
Power saving protocol (PSP) and Nonpower saving protocol
The power saving protocol allows computers (usually
portable computers) to power up only part of the time
to conserve energy. Ifa radio node is using PSP to
communicate with the network, the access points
must be aware of this mode and implement additional
features such as message store and forward. While
the PSP mode does provide greater battery life, it
does increase the response time for the data.
Registration modes
Note that NorrAiMN mode does not
wppon Power Saving Protocol on
Radio end nodes 1599 Figure 3],
The Telxon Mobile Node can be used in either
ARLAN (default), PSP or NonARLAN registration
model
ARLAN mode (microceilular architecture)
A hightraffic radio network with one or more access
points placed on a cabled backbone LAN, and Telxon
Mobile Nodes installed in remote radio nodes (PCs
and notebook computers).
Each radio node registers to and communicates with
the closest, or userspecified Telxon access point, The
access points perform routing functions by moving
data packets to and from the cabled LAN and remote
radio nodes. This mode provides automatic circuit
handoff and message forwarding, as a Telxon Mobile
Node user roams between LAN access point
microcells, In this way, largescale‘ wireless LANs are
configured.
PSP
Same as ARLAN Mode‘ except that it is used for
Telxon Mobile Nodes installed in remote
batterypowered radio nodes such as notebook
computers. The power saving protocol conserves
battery power at the cost of decreased throughput by
periodically turning off the radio (See the Power
saving protocol section in this chapter)
NonARLAN mode
A low-traffic radio network comprised strictly of radio
nodes (PCs, file servers, notebook computers, etci)
fitted with the Telxon Mobile Node.

In Non»ARLAN mode, access points are not used‘ and
ARLAN microcellular architecture is not utilized,
since data is transmitted directly between the radio
nodes. The radio nodes can operate in a peertopeer, or
in a clientserver network relationship depending on
the network operating system being used,
The Telxon Mobile Node can be used in a variety of
network system configurations. Examples of some
common system configurations are outlined below,
and shown on the pages that follow’ along with a brie!"

allowing remote workstations equipped with Telxon
Mobile Nodes to register to the access points. The
ARLAN protocols allow remote workstations to move
from the domain ofone microcell to another. The
process is seamless and transparent‘ and the
connection to the file server or host is maintained
without disruption. This configuration is particularly
useful with portable or mobile workstations.
