Motorola’s MOTOMESH Duo is a high performance, 802.11 a/b/g meshed Wi-Fi solution
designed to meet strict cost per square mile and ROI targets. MOTOMESH Duo is part of the
MOTO wi4™ portfolio of broadband wireless access technologies, and delivers a new level of
economic flexibility and investment protection to municipalities and service providers.
MOTOMESH Duo leverages Motorola’s field proven, MeshConnex™ routing engine and One
Point Wireless Management™ system to meet the challenges of demanding multi-use
networks. Its small size, minimal visual impact and low power consumption increases
mounting location flexibility and enables rapid deployment. MOTOMESH Duo devices are
available in three different radio configurations:
Chapter
1
• 2.4 / 5.4 GHz (single mesh)
• 2.4 / 5.8 GHz (single mesh)
• 2.4 / 4.9 GHz (dual mesh)
MOTOMESH Duo devices can be deployed in a variety of meshing configurations depending
on the radio configuration ordered:
• 2.4 GHz client access / 2.4 GHz meshing – In this configuration the second radio is
disabled and the 2.4 GHz radio is used for client access and for inter-nodal meshing.
• 2.4 GHz client access / 5.4 GHz meshing – In this configuration the 2.4 GHz radio
is used for client access and the 5.4 GHz radio is used for inter-nodal meshing.
• 2.4 GHz client access / 5.8 GHz meshing – In this configuration the 2.4 GHz radio
is used for client access and the 5.8 GHz radio is used for inter-nodal meshing.
• 2.4 GHz client access / 2.4 GHz meshing | 4.9 GHz client access / 4.9 GHz
meshing – In this configuration the 2.4 GHz radio is used for client access and inter-
nodal meshing. The 4.9 GHz radio is also used for 4.9 GHz client access and internodal meshing. This configuration is referred to as Dual Mesh.
MOTOMESH Duo devices can also be ordered in AC and DC versions.
1-1
Chapter 1: System Overview
All MOTOMESH Duo 2.1 Infrastructure Devices require professional
installation to ensure the installation is performed in accordance with
Motorola installation standards and that regulatory requirements are met.
MOTOMESH Duo 2.1 Network Components
.............................................
.
.
A MOTOMESH Duo 2.1 network is comprised of the following components.
• Intelligent Access Points (IAPs)
• Mesh Wireless Routers (MWRs)
• Supporting networking equipment
Intelligent Access Point
A MOTOMESH Duo device can function as an IAP (gateway) or an MWR. All MOTOMESH
Duo devices ship from the factory as IAPs. If an IAP does not detect a wired connection it
will convert to an MWR thus removing itself as a valid gateway to the wired network. This
prevents routing holes from forming in the network. IAPs (functioning as MWRs) will still
participate in the mesh and will forward traffic to an alternative IAPs (gateways). A node can
also be specifically set as an IAP or an MWR using the One Point Wireless Manager™
application or the device webpage.
Intelligent Access Points:
• Support 802.11 a/b/g Wi-Fi client access.
• Support all 802.11 client security methods (open, WEP, WPA/WPA2 RADIUS,
WPA/WPA2 PSK).
• Support 15 Virtual Access Points per radio for client access.
• Support Dynamic Route Selection via the MeshConnex™ routing engine.
• Support Automatic Load Balancing.
• Support 128bit AES encrypted Secure Mesh inter-nodal links.
• Are equipped with two Ethernet interfaces one of which can source standards
based 802.3af Power over Ethernet (PoE) (to power an external IP enabled
device such as a surveillance camera) or Canopy PoE to power Motorola
Canopy subscriber modules.
• Offer fast and easy deployment via a pivot mounting bracket.
• Designed with a rugged NEMA 4 outdoor enclosure.
1-2
Chapter 1: System Overview
With the addition of each IAP additional network capacity is added.
Mesh Wireless Router
When a MOTOMESH Duo device operates as a Mesh Wireless Router (MWR), its primary
function is to seed and extend the range between IAPs and wireless clients while
simultaneously increasing the spectral efficiency of the network.
Mesh Wireless Routers:
• Range extension for all other network devices.
• Support 802.11 a/b/g Wi-Fi client access.
• Support all 802.11 client security methods (open, WEP, WPA/WPA2 RADIUS,
WPA/WPA2 PSK).
• Support 15 Virtual Access Points per radio for client access.
• Support Dynamic Route Selection via the MeshConnex™ routing engine.
• Support Automatic Load Balancing.
• Support 128bit AES encrypted Secure Mesh inter-nodal links.
• Are equipped with two Ethernet interfaces one of which can source standards
based 802.3af Power over Ethernet (PoE) to power external IP enabled devices
such a surveillance camera. This allows a network of IP-enabled devices to be
directly addressed, accessed and managed over the network.
• Offer fast and easy deployment via a pivot mounting bracket.
• Designed with a rugged NEMA 4 outdoor enclosure.
Supporting Networking Equipment
Additional networking infrastructure is required to support a MotoMesh Duo network. This
includes an enterprise grade server to provide network services such as DHCP and DNS, as
well as host the MotoMesh Duo management software (One Point Wireless Manager™. A
RADIUS server may also be present. Switching and routing network equipment is also
required. Our small system reference design utilizes a single Layer 3 switch which provides
switching and routing within the same device.

Small System Reference Design
This section details a small system reference design. By understanding the small reference
design one can apply these details to larger networks. A small system reference design is
defined as a network in which the network servers and associated networking hardware are
located at a central location. Wireless or wired bridging may be used to provide connectivity
between the Intelligent Access Points and the switch / router backend.
Chapter
2
Our small system reference design has the following attributes:
• Support for at least 20 IAPs (gateways).
• All IAPs and MWRs will utilize DHCP for network addressing.
• The Network will be configured and managed with the One Point Wireless
Manager™ application residing on a RedHat ES 4 Linux server.
• A Windows 2003 RADIUS server will provide authentication for Secure Mesh.
• The standard small network design does not include server or network hardware
redundancy.
Network Requirements
.............................................
.
Network Servers
There are two network servers used in the small system reference design. The following is
the recommended hardware configuration for these two servers. Variations from the
recommended hardware configuration may result in inadequate system performance.
• Enterprise grade server (e.g. Hewlett-Packard ProLiant DL360-G5 3.00GHz
Server)
• Minimum 2 GB of RAM
• (2) 36.4 GB 15K RPM SCSI Hard Disk Drives
2-5
Chapter 2: Network Setup
Figure 2-1 HP DL360 G5 server
• Monitor
• Keyboard
• Mouse
These requirements are an approximate estimate intended to allow for
maximum scalability while supporting rapid system response time. As a
minimum, we recommend 2 GB of system memory and redundant hard
drives with a hardware RAID controller of server quality.
One Point Wireless Manager Server
• The One Point Wireless Manager™ server in our reference design server hosts
the One Point Wireless Manager™
configuration and network management. DHCP and DNS will also be configured
on this server and are part of the Linux operating system.
RADIUS - (Optional)
• The Windows 2003 server is optional and is used to support EAP-TTLS Secure
Mesh. Juniper’s Steel Belted Radius application will be configured on the
Windows 2003 server since it supports EAP-TTLS based authentication. The
Windows 2003 Server also provides certificate services which will be used to
generate certificates to support EAP-TTLS. Our RADIUS server could also be
used for certificate based 802.11 client authentication and or store 802.11 client
usernames and passwords. A RADIUS server for Secure Mesh is not required if
PSK Secure Mesh is used instead.

Chapter 2: Network Setup
EAP-TTLS Secure Mesh
The MotoMesh 2.1 architecture provides a set of features designed to help network operators
secure the mesh network. These security features can help to protect the mesh network from
intruders and attackers.
It is important to distinguish between the security provided by the MotoMesh architecture
(Secure Mesh) and the security features provided for standard 802.11 clients (e.g. laptops,
mobile Wi-Fi devices, etc.). Mesh Security applies between all of the mesh-enabled devices
that form the mesh network. 802.11 client security (e.g. WEP, WPA-PSK, etc.) is completely
independent of mesh security and is detailed in the WMS Administrator’s Guide.
EAP-TTLS Secure Mesh uses Public Key Infrastructure (PKI) certificates to authenticate the
network infrastructure, a RADIUS server, and a unique user ID and password to uniquely
authenticate each mesh device. EAP mode supports MIC codes and encryption, where
available. EAP mode supports centralized control of per-device authentication credentials by
the RADIUS server, so a compromised device's credentials can be individually revoked
without having to change keys on other devices. Session keys are automatically derived
based on the EAP authentication and rolled periodically at a rate controlled by the RADIUS
server. EAP mode is recommended for medium- or large-sized networks or any network that
requires per-device authentication or centralized control over credentials. EAP mode
requires the "R0 Key Holder" (R0KH) service. The R0 Key Holder service acts as a key
cache, speeding up key generation for devices that already have a valid session key from the
RADIUS server, similar to the R0 Key Holder defined for 802.11r. The R0KH service is
included as part of the Linux environment setup.
Secure Mesh can also be configured to use PSK thus eliminating the RADIUS requirement. Please
see the WMS Administrator’s Guide for detailed steps.

Overview
The standard small system reference design includes a Cisco 3750 L3 Switch which supports
20 Intelligent Access Points (IAPs). Four switch ports (ports 1-4) are also available for
network servers such as the One Point Wireless Manager™ server and RADIUS. IAPs are
connected to L3 switch (ports 5-24) via one of three methods:
• Direct Ethernet
• Connection via a wireless bridge (Motorola Canopy™ System)
• Connection via a wireline media converter (e.g. Ethernet over Fiber media
converter)

and the server network 172.31.0.0/16 (e.g. inter VLAN routing between VLANs
1, 24, 31, and 49).
• DHCP relay from the wireless subnets to the DHCP server running on the One

By default, the 3750 Switch drops IP directed broadcasts; thus preventing them from being
forwarded. The One Point Wireless Manager™ application utilizes SNMP broadcasts for
automatic network discovery. We have enabled IP directed broadcasts in the 3750 L3 switch

Chapter 2: Network Setup
in order to prevent the switch from dropping these discovery packets. See Appendix A for
detailed steps on how to configure the IP directed broadcast feature on the 3750 L3 switch.
VLAN Setup
The L3 network switch provides the ability to segment management and user traffic using a
combination of VLAN tagging and firewall access control rules, see Figure 2-4. In the small
system reference design the L3 switch has been configured with the following 4 VLANs each
representing a different IP subnet per our IP plan:
• VLAN 31 is configured on Ports 1-4. Ports 1-4 are access ports only (non-tagged)
• VLAN 1 is the native VLAN of the L3 switch by default. Ports 5-24 have been
and are used by network servers such as the One Point Wireless Manager™
(172.31.0.20/16) and RADIUS. VLAN 31 has the address of 172.31.0.2/16. Note
how the second octet of the IP address (31) is aligned with the VLAN number. This
has been done to simplify the IP design.
configured as trunked ports and have VLAN 1 in their allowed VLAN list. VLAN 1 has
the IP address of 10.1.0.1/24. It has been configured to support non VLAN capable
devices such as cameras and other IP devices. This VLAN is also configured with an
IP helper address of 172.31.0.20 (The address of the Wireless One Point Manager™
server) to service any DHCP requests received on this VLAN.

• VLAN 24 is also included in the allowed VLAN list on ports 5-24. VLAN 24 has the
address of 10.24.0.1/16. VLAN 24 has been configured to be used as a
management VLAN. The management VLAN is used to communicate management
data from the One Point Wireless Manager™
VLAN is also configured with an IP helper address of 172.31.0.20 (The address of
the Wireless One Point Manager™ server) to service any DHCP requests received
on this VLAN.
• VLAN 49 is also included in the allowed VLAN list on ports 5-24. VLAN 49 has the
address of 10.49.0.1/16. VLAN 49 has been configured to be used by wireless
clients. As mentioned previously a MOTOMESH Duo device supports up to 15
Virtual Access Points (VAPs) per radio. Each VAP can be configured to have a
unique VLAN. Thus, in this example, VLAN 49 has been created to support a client
VAP. Note that this VLAN tag will be stripped off prior to data being sent to client
devices (VLAN tag stripping is on by default on client VAPs). Traffic that originates
from a client would be tagged with VLAN 49. This VLAN is also configured with an IP
helper address of 172.31.0.20 (The address of the Wireless One Point Manager™
server) to service any DHCP requests received on this VLAN.

VLAN Examples
In order to better understand how VLANs are used in our small system reference design let’s examine
how traffic traverses these VLANs. In the example below the One Point Wireless Manager
connected to port 1 and our IAP is connected to port 18. Management VLAN 24 has been configured on
our IAP as well as DHCP. When the IAP is powered on it obtains an IP address in the follow steps:
1. The IAP requests an IP address via DHCP. This request is sent over VLAN 24.
2. The 3750 switch receives the DHCP request on Port 18 which is configured to accept packets on
VLAN 24. VLAN 24 is configured on the L3 switch to forward DHCP requests to the One Point

MOTOMESH Duo Device Defaults
MOTOMESH Duo devices come from the factory with the following default settings:

Chapter 2: Network Setup
• All devices are IAPs
• DHCP enabled
• VLAN support enabled
• Management configured as VLAN 4095. A management VLAN of 4095 means
• Backhaul detection on – If a MOTOMESH Duo device does not detect a wired
untagged. Thus when a MOTOMESH device requests an IP address for the first time
the DHCP request will come in as untagged and will be serviced by VLAN 1. Thus
the device will receive a 10.1.X.X/16 address (e.g. if the small system reference
design defaults are used). The management VLAN can then be changed to another
VLAN e.g. VLAN 24 used in the reference design. (The management VLAN would
be changed to VLAN 24 and the device rebooted. The device would then get a
10.24.x.x address).
backhaul connection it will convert itself from an IAP to an MWR. The Backhaul
detection feature is comprised of active ping and link layer detection. By default, the
IAP will ping the gateway address received in the DHCP reply. If an IAP is statically
configured then an IP address will need to be entered into the backhaul detection
settings (in the One Point Wireless Manager™ application or via the webpage
interface) for the Backhaul Detection feature to operate correctly. Improper
configuration will lead to the IAPs configuring themselves to operate in degraded
mode which is an IAP acting as an MWR.
If an IAP is addressed via DHCP, the gateway address received in the DHCP reply
will be used as the logical address the IAP will ping for logical backhaul detection.
If the IAP is statically configured a valid “pingable” IP address must be configured
in the backhaul detection settings or the IAP will enter degraded status and
operate as an MWR.
