CLARION M10II INTRODUCTION
GETTING STARTED GUIDE PAGE 1
1. INTRODUCTION
1.1 WELCOME
Thank you for choosing Clarion’s M10II multi-point, multi-addressing
modem. The M10II is pre-configured to operate right out of the box to
connect multiple workstations or multiple LANs (Local Area Networks)
with the speed and accuracy of a wired LAN without the need for wires.
Just plug them in, one M10II per wired network segment and away you go.
The M10IIs will automatically sense the local traffic and build internal
tables.
The M10II is ideal for forward-thinking organizations that require 10 Mbps
(Megabits Per Second) LAN performance across the street or just across the
hall and want to maintain the flexibility and cost control that management
of their own network provides. There is no reliance on wire installers or
fees to pay for telephone access. The M10II uses RF (Radio Frequency)
technology operating at the same data rate as standard wired connections,
allowing you to connect networks simply by plugging in the M10IIs. The
M10II can reduce the cost associated with expansions or changes within
your company by providing you with an easy and cost effective way to
connect multiple workstations or multiple LANs without the constraints
associated with wired connections.
1.2 M10II, THE NEXT GENERATION OF THE M10 FAMILY
The M10II is the second generation Clarion product in the M10 family.
The M10 is a wireless, single address modem that connects two media
points together. The M10II is a wireless multi-point, multi-addressing
modem able to accommodate up to 200 NICs (Network Interface Cards)
per network segment. The M10II offers the functions and features of the
original M10 modem, as well as providing an important additional
advantage to customers. The upgraded feature of the M10II is the
extension of retransmission protocol to multi-source address situations.
This key new feature of the M10II required substantial development. In
wired communications frames are lost mainly by collisions. However, in
wireless communications frames can be lost by fading, weak signals or
interference. Thus, all radio modems require lower level retransmission of
frames to provide adequate reliability and throughput. The original M10
was designed for connection to a single Ethernet card, either in a

CLARION M10II INTRODUCTION
GETTING STARTED GUIDE PAGE 2
workstation or a router. Both the workstation and the router employ a
single 802.3 source address that the M10 learns and uses for the
retransmission protocol. Thus, when the M10 receives a frame with the
destination address equal to the address of the attached Ethernet card, the
M10 sends the RF acknowledgment frame to the source modem. The
M10II can do this for multiple Ethernet source addresses.
There are two important situations in which the above single-source-
address constraint is violated: 802 MAC (media access control) level
bridging and wireless interconnection of 10BaseT hubs. Each of these is
important for general networking, and each presents the modem with
multiple source addresses from the wired side. The M10II maintains a list
of its wired side source addresses, and will acknowledge RF frames
addressed to these. Thus, the key new feature of the M10II is extension of
the retransmission protocol to multi-source-address configurations.
The M10II maintains acknowledgment-address tables, however, it is not a
bridge. For 802-compliant bridging the M10II can be connected to a MAC
bridge, with the MAC bridge providing address tables obtained via the
spanning-tree algorithm.
1.3 M10II APPLICATIONS
The M10II is a robust, 10 Mbps (Megabits Per Second) wireless multi-
point, multi-addressing modem designed to support wireless connections
across town, across the street or just across the hall for IEEE 802.3 and
Ethernet II (TCP/IP) LANs. It provides all the functionality of wired
LANs, without the physical constraints of the wire.
The M10II connects multiple workstations or workstations on multiple
wired Ethernet LANs. It builds and maintains a list of the workstations on
the wired Ethernet LAN to which it is connected, and shares this
information with other M10IIs. When a user on a wired LAN wants to
ACROSS TOWN

CLARION M10II INTRODUCTION
GETTING STARTED GUIDE PAGE 3
send data to a user on another wired LAN, the M10II will transmit the data
and acknowledgments to the appropriate M10II connected to the other
wired LAN. The M10II senses local traffic, builds internal tables and
operates the re-transmission and packet filtering protocols to insure that
useless information is not transmitted. The M10II adapts immediately
without user intervention.
For the OEM (original equipment manufacturer) desiring to integrate the
M10II with a bridge or router, the multi-source-address checking features
make the M10II perfect for modest size multi-point RF (Radio Frequency)
connections.

2.1 SYSTEM REQUIREMENTS AND CHARACTERISTICS
2.1.1 COMPATIBILITY
The M10II is compatible with all IEEE 802.3 and Ethernet II LAN devices,
all operating systems and all protocol stacks. The M10II is completely
transparent to the network operating system.
2.1.2 RELIABILITY
The retransmission function at the radio MAC layer provides enhanced
reliability and throughput by avoiding long time-outs caused by
retransmissions performed at higher levels.
2.1.3 DATA SECURITY
Security is a great concern with any data transmission system. Wireless
data systems may be of even greater concern because of the leakage of
transmitter waveforms beyond the intended receiver sites. The M10II
offers excellent security without incorporating conventional cryptography.
Of course, the user always has the option to add conventional data
encryption technology to the most critical applications.
Most commercial spread spectrum manufacturers use fixed spreading codes
in their products. The M10II radio, with Direct Sequence Spread Spectrum
(DSSS), uses continuously changing, pseudo-random spreading codes, in
which each symbol is encoded with a different spreading code.
Furthermore, the user may select from 64k different sequences to determine
the order in which the spreading codes are used; this provides excellent
security against eavesdropping by unintended parties.
2.1.4 TARIFFS AND LICENSES
No FCC License is required.

2.1.5 FLEXIBLE MANAGEMENT
The M10II includes a complete set of management and configuration tools
for the network administrator.
2.1.6 NETWORK FLEXIBILITY
•Network segments can be set up or augmented without installing or
moving wires.
•The M10II can be used for point to point or multi-point topologies by
simply adding M10IIs to Ethernet network segments.
•The number of Ethernet segments that may be supported is unlimited
due to address filtering which effectively isolates network traffic.
•Each Ethernet segment may contain up to 200 PCs or NICs.
