1Introduction
Terragraph Network
Terragraph is a 60GHz, multi-node wireless Software Defined Network (SDN) that
enables high-speed Internet connectivity in multiple environments. The network
operates best in Line-Of-Sight (LOS) conditions to maximize connectivity.
Terragraph is a distribution-level network designed to augment and expand a fiber
optic network. That is, Terragraph is a high-speed backbone network to which
other networks are connected. When combined with fixed access connections or
Wi-Fi access points, Terragraph is a simple and easy-to-install solution to achieve
street-level coverage with high speeds.
A Terragraph network is composed of individual nodes. There are two types of
nodes in a Terragraph network – Distribution Nodes (DNs) such as the MLTG-360,
and Client Nodes (CNs) such as the MLTG-CN. DNs are the backbone of the
Terragraph network that distribute Internet connectivity from one or more fiber
optic Points of Presence (PoPs) over multiple hops to CNs. DNs and CNs are
connection points for client networks, wireless access points, and other customer
premise equipment (CPE) to connect to the Internet.

Each node in a Terragraph network is a Layer 3 (L3) router. Nodes route traffic within
and between the Terragraph network and attached access networks using routing
information provided by the Open/R protocol. The over-the-air link protocol
between Terragraph nodes uses a modified version of the Directed Multi-Gigabit
(DMG) physical layer (PHY) of the IEEE 802.11ay standard.
The MLTG-360 has up to 4 radios for 360 coverage. Each radio is equipped with a
256-element beamforming phased array antenna to form high-quality
communication links between nodes supporting up to 1.8 Gbps bi-directional
throughput, using primarily LOS paths but also reflection paths. Links between
MLTG-360 devices can be formed at distances of up to 300 meters. The multiple
propagation paths are called micro-routes, and each micro-route is a potential
communication link between nodes. Each node selects the strongest
communication link from the many possible propagation paths between nodes.
The phased array antenna allows Terragraph to establish links that mitigate co-
channel interference that often prevail in dense urban environments.
A Distribution Node such as the MLTG-360 serves as the demarcation between the
Terragraph network and the provider’s backbone network. While Terragraph is a
wireless technology, there must be at least one wired Terragraph PoP node
connected to an upstream IPv6-enabled network.
Connecting to the Web Interface
The MLTG-360 offers a user-friendly web-based management interface for the
configuration of all the device’s features and network settings. Any PC directly
attached to the unit can access the management interface using a web browser.
The web interface is accessible through the Management PoE In port. To access the
MLTG-360’s web interface, follow these steps:
1. Connect a PC directly to the MLTG-360’s MGMT PoE IN port.
2. The MLTG-360 is configured as a DHCP Client and receives its IP dynamically.
Check the DHCP server on the PC for the assigned address.
3. In case the DHCP server is unavailable, the MLTG-360 uses the fallback IP
192.168.1.20 and subnet mask 255.255.255.0.
Set the PC IP address to be on the same subnet as the MLTG-360 MGMT PoE IN
port. The PC IP address must start with 192.168.1.x and use subnet mask
255.255.255.0.
4. Enter the MLTG-360 IP address into the web browser address bar.

After logging in to the web interface, the Dashboard screen is displayed. The
Dashboard shows basic settings and status of the device regarding system
information, network, and topology.

System The following items are displayed in this section:
◆Status:
■Length of time the device has been up.
■Software version number.
■Device serial number.
■MAC address of this node.

◆Radio MAC:
■MAC address of each radio. The number of radios and their position varies
by model:

■Complete list of the device’s MAC addresses and correspondent network
interfaces: Management port, SFP+ port, and four PoE Out ports.
■Hovering the pointer over any port on the list highlights its location on the
bottom view graphic.

◆Interface IP:
■Management Interface: Bound to the PoE In port. This traffic is separated
from the access network and should be assigned to a subnet different from
the uplink interface.
■Control Interface: The logical interface that the POP node uses to
communicate with the external controller or other management tools.
■Terragraph LAN Interface: The logical routing interface in Terragraph
networks. The Terragraph LAN interface is only active in Terragraph mode.

■Link Uptime: Length of time the link has been up.
◆Terragraph Network Routing Table:
■Destination: Destination IP address/subnet.
■via: Next hop.
■Interface: Output interface.
Note: The 60 GHz interface is referred to as terraX. Each radio includes 16 terra
interfaces. Therefore, terra0–terra15 are interfaces of Radio A, terra16–terra31 of
Radio B, terra32–terra47 of Radio C, and terra48–terra63 of Radio D.
Topology Displays the status of the links. On a POP node, this section shows the status of

Network Configuration
The management interface is bound to the physical PoE In port. The management
interface is isolated from the access network. There are two available configuration
modes: DHCP or static. In both modes, the configuration of IPv4 and IPv6 addresses
depends on the capability of the management network.
Management The management port is in DHCP mode by default. The following options are
displayed in this section:
