3.1. Introduction
3.1.1. Cisco FM3500 Endo
The Cisco FM3500 Endo radio transceiver
Introduction
The Cisco FM3500 Endo (model FM3500) is designed to operate in the
sub-6 GHz range as a wireless data backhaul link. In non-technical terms,
this means it is designed to function as an intermediate radio link between
a core wired data network and a sub-network. The unit must be connected
to one or more external antennas. The unit is designed primarily formobility
applications based on Fluidity technology, in which specialized antennas
need to be deployed (for example, train-to-ground, automated mining
vehicles, industrial automation and similar applications).
The Cisco FM3500 Endo is configured as a multiple input/multiple output
(MIMO) 2x2 radio transceiver. In a 2x2 scenario, two separate spatial

streams are transmitted by one transceiver unit, and are available to be re-
combined by the radio chipset of a second transceiver unit.
Data throttling
The unit's FluidThrottle functionality allows you to specify the maximum
amount of data throughput the unit will be required to handle at any time.
The unit's throughput capacity can be upgraded to different levels using
software plug-ins.
MPLS protocol
Two different Multi-Protocol Label Switching (MPLS)-based protocol
versions can be chosen. If a newer network is being built or upgraded, the
advanced Prodigy 2.0 protocol can be selected to boost performance. If
an older network incorporating Fluidmesh components is being upgraded,
the Prodigy 1.0 protocol with limited functionality can be selected to
guarantee compatibility. Prodigy uses a traffic optimization algorithm that
allows every Fluidmesh radio to assign a specific priority level to every
forwarded data packet.
Unit configuration
The unit is compatible with Fluidmesh RACER™. This is a centralized, web-
based interface that allows you to configure, monitor, and troubleshoot the
unit (and in certain cases, the entire wireless network) in real time, without
the need for any offline software. In cases where an initial connection
cannot be made to the internet, the unit can be configured using a built-in
offline Configurator interface.
Environmental rating
The unit is certified for outdoor usage, equipped with vibration-proof
connectors, and designed for fast installation and enhanced reliability in
harsh environments.
Product specifications
For detailed product specifications, refer to the product data sheet for the
Cisco FM3500 Endo.
Transceiver and gateway unit power consumption
In service, Fluidmesh transceiver units and gateway units consume

IMPORTANT
In service, transceiver and gateway units will consume power
at various levels between the quoted lower limit and upper limit,
depending on data traffic load, signal strength, environmental
conditions such as line-of-sight and atmosphericmoisture, and
other factors.
Note that the power consumption of transceiver units tends to
be affected in inverse proportion to the unit temperature (in
other words, power consumption tends to rise when the
temperature of the unit falls, and the other way around).

3.2. Fluidmesh Architecture
3.2.1. Overview
Wireless network architectures
Depending on the network design and the type of components used, the
Cisco FM3500 Endo can be used to create wireless network architectures,
including:
•Point-to-point (P2P) links.
•Mesh networks.
•Mobility networks.
•Mixed networks that are capable of using any combination of types
listed above.
3.2.2. Fluidmesh technologies
Prodigy
Prodigy is Fluidmesh's proprietary implementation of the Multi-Protocol-
Label-Switching (MPLS) standard.
Prodigy 2.0 offers greatly improved performance compared to Prodigy 1.0.
New features include:
•Fluidity (through software plug-ins)
•Traffic engineering
•Advanced Quality of Service (QoS)
Note that Prodigy 2.0 is only compatible with device firmware versions 6.5
and higher.
IMPORTANT
A Fluidmesh device only features Prodigy selection if the
installed Prodigy engine includes the selection feature.
Fluidmesh devices that are designed to operate exclusively in
Bridge Mode (in other words, point-to-point configuration) do
not feature Prodigy.

Getting Started

Page 16 of 177
Fluidity
Fluidity is the proprietary track-side and vehicle-to-ground data transfer
protocol developed by Fluidmesh.
Fluidity supports video, voice and data communication, ensuring usable
throughput of up to 500 Mbps for high-speed railway trains and other
vehicles capable of traveling at up to 225 mph or 360 Km/h (under optimal
wireless link conditions).
For detailed information on the operational concepts, and instructions on
how to configure Fluidity, refer to the Fluidmesh Networks Fluidity
Configuration Manual.
FM Racer
RACER™ is Fluidmesh's web-based configuration portal. It is the primary
interface with which to configure Fluidmesh radio devices.
You can operate FM Racer using any internet-connected computer with a
web browser.
3.2.3. Point-to-point wireless bridge
A point-to-point wireless bridge allows two local networks to communicate
with each other. A simplified example is shown in Figure 1 (page 17).
IMPORTANT
Prodigy 1.0 and Prodigy 2.0 are not compatible with each other.
Do not implement the two protocol versions within the same
network.
If you are expanding an existing network using new Fluidmesh
hardware components, make sure that all components are
compatible with each other by:
Upgrading all network components within the same
network to firmware version 6.5 or higher, and:
Configuring all network components within the same
network to operate using either Prodigy 1.0 or Prodigy
2.0.
Use of Prodigy 1.0 is only recommended if the network contains
older Fluidmesh devices that are not compatible with Prodigy
2.0.
Select the Prodigy version you need by using the General Mode
page of the Configurator interface.
IMPORTANT
For a detailed description of the differences between FM Racer
and the local Configurator interface, refer to “Device
configuration using the configurator interface” (page 46).

Page 17 of 177
In context of the overall network architecture, the two local networks are
called network segments.
Figure 1. Point-to-point network architecture
All network activity that takes place on wireless bridges is 'transparent' to
the network hosts. In other words, a wireless bridge forwards packets
from one network segment to another according to a 'Forwarding table'. The
forwarding table is built by learning the network topology from analysis of
incoming traffic.
Inthis configuration, no explicit interaction takes place between the wireless
bridge and the network hosts. The network segments on either side of the
wireless bridge share the same IP subnet. Therefore, each network host
must use a unique IP address within the subnet.
3.2.4. Mesh network architecture
Fluidmesh Networks offers wireless networking solutions that are based
on the mesh networking architecture, but can also fill more traditional
networking roles if needed. This allows substantial reliability and flexibility
advantages when compared to traditional wireless solutions.
A simplified example of a wireless mesh network is shown in Figure 2 (page
18). In such a network, every Fluidmesh hardware componenttransmits the
data packets that come from the components directly linked to it.
In a reliable mesh network with an acceptable amount of redundancy, every
stream of data packets may reach the base station through any of a variety
of paths. The CiscoFM3500 Endo is designedtoact asan 'intelligent router'
that is able to forward packets coming from other

Page 18 of 177
Fluidmesh components in real time, based on an optimal, software-
determined path. In addition, the absence of any single point of failure
greatly increases reliability when compared to any other wireless or wired
data-transmission technology.
Figure 2. Fluidmesh Mesh Networking Architecture
3.3. Fluidmesh network addressing
3.3.1. Bridge IP addressing
If needed, the Cisco FM3500 Endo can be operated in Bridge mode. This
creates a single point-to-point connection between two network segments.
A simplified example of a Bridge mode connection is shown in Figure 3
(page 19).
As shipped from the factory, the wired ethernet ports of all Fluidmesh
hardware components are assigned the same default IP address of
192.168.0.10/24.
No default IP address is associated with the wireless interface.

Figure 3. Wireless network architecture (bridge configuration)
3.3.2. Unit identification and addressing
Mesh- and bridge-capable radio transceiver identification
Regardless of its configuration and operating mode, every Fluidmeshradio
transceiver is shipped from the factory with a unique unit identification (ID)
number. This number always takes the following form:
5.a.b.c
The triplet a.b.c uniquely identifies the individual physical hardware unit,
and cannot be changed.
The unit ID number is used to identifythe physical hardware units within the
configurator interface that is used for configuration of the unit.
A simplified diagram demonstrating the relationship between a wired LAN,
and a linked meshradio network containinga mesh end unit andmesh point
units, is shown in Figure 4 (page 20).
CAUTION
This section contains theoretical explanations of the underlying
concepts behind mesh network addressing, and is intended for
use by qualified network engineers only.

mesh network architecture, it can be set to operate in either of two operating
modes:
•Mesh Point Mode: This is the default operating mode. Each radio
transceiver unit that is part of the network, but is not connected to
the wired LAN backbone, must be set in Mesh Point mode.
•Mesh End Mode: Each radio transceiver unit that is part of the
network and is connected to the wired LAN backbone must be set
in Mesh End Mode. A Mesh End transceiver unit is always the
junction point between the wireless network and any IP-based wired
network.
