Introduction
Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide
Features and Benefits
SPEEDLAN 9200 Features
The SPEEDLAN 9000 series introduces the second generation of wireless routers. The
SPEEDLAN 9200 offers the following new features:
• New Wireless Mode parameters (e.g., 5GHz OFDM, 2.4GHz DSSS or
2.4GHz OFDM), Preamble, Tx power and SSID). For more information, see
Configuring the Radio Parameters, page 3-38.
• Double the transmission rate with turbo mode, up to 108Mb/s for 5GHz
OFDM. For more information, see Configuring the Radio Parameters,
page 3-38.
• You can allow a mesh node in a 9200 network to communicate with a
SPEEDMesh-enabled client in adhoc mode. For more information, see
Enabling/Disabling the SPEEDMesh-Enabled Client, page 4-5.
• Provide network security between SPEEDMesh-enabled clients (PDAs and
laptops) and SPEEDLAN 9200 routers via WEP. In a SPEEDLAN 9200 network,
you can authenticate a SPEEDMesh-enabled client with a standard security
mechanism called Wired Equivalent Privacy (WEP). WEP encrypts data that is
transmitted over the wireless LAN. WEP protects the wireless link between
clients and access points. Network administrators can control access via
standard 802.11 client using WEP. For more information, see B. Enabling
WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200,
page 4-4.
1-2
• Provide DHCP relay: This first release of the SPEEDLAN 9200 shall use the
DHCP relay function to forward DHCP requests from non-SPEEDLAN wireless
clients to one or more DHCP servers. Those DHCP servers maybe suitably
configured SPEEDLAN 9200 routers (in which they won’t relay), or they may be
dedicated servers, reachable through the Ethernet interfaces of one or more of
the SPEEDLAN 9200 routers. To configure DHCP relay, see Configuring
DHCP Relay, page 3-50.
• Support for DC input sources: Devices that lack AC power will require DC-to-
DC supply.
• At this time, star mode (i.e., base, point-to-point and CPE)
is not available. Only mesh mode is available.
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03
The SPEEDLAN 9200 offers the network manager unsurpassed flexibility in meeting the
challenges of designing, building and managing today's wireless broadband networks.
In a mesh topology, the SPEEDLAN 9200 routes traffic around physical limitations,
eliminating the line-of-sight (LOS) issue present in star topology-only networks. Each
mesh router will communicate with other mesh routers in a radius of up to 2 miles
depending upon the model and signaling rate selected. This creates a multi-hop IP
routed cell: self-healing, load balancing, and scalable network. By removing LOS
issues caused by large buildings, hills, and other obstructions, service providers can
reduce network deployment costs while maximizing their broadband wireless
investment and reach new markets that could otherwise not be served.
For more information about mesh, see SPEEDLAN 9200 Mesh Protocol -- How It Works
in Mesh Cells, page 1-6.
ISP Functionality
The SPEEDLAN 9200 products are tailored to fit the needs of Internet Service Providers
and Broadband Telecommunications Providers. Two features particularly useful to
Internet Service providers are Network Address Translation (NAT) and Dynamic Host
Configuration Protocol (DHCP). NAT helps to ensure network security and allows an
entire company to share a single global IP address for communication on the Internet.
This enables companies to communicate with other devices on the Internet. DHCP
servers provide efficient use of IP addresses by assigning them dynamically or statically
to the wireless router location. DHCP allows network administrators to dynamically
assign IP addresses for the period of time needed to connect to the Internet or network.
IP Router Functionality
The SPEEDLAN 9200 is a highly configurable wireless IP router which supports mesh
topologies. In addition to being configurable via a standard web browser, the
SPEEDLAN 9200 also contains a firewall to control incoming and outgoing traffic,
preventing unauthorized access.

Configuration Management
The SPEEDLAN 9200 Configurator is a web-based management tool that allows a
network manager to configure routers. For more information, see General Functions of
the Configurator, page 3-1.
SPEEDManage
The SPEEDManage suite offers network management tools to help you troubleshoot

routers.
• You can recover lost IP addresses. (Use IP Recover in SPEEDManage.)
Note: Advanced Encryption Standard was adopted by the National Institute of
Standards and Technology in October of 2000. AES presents a new level in computer
networking security, especially important in wireless communications because wireless
circuits are easier to tap than their hard-wired counterparts.
AES is more difficult to crack than its predecessor Data Encryption Standard. These
routers use an AES 128-bit encryption key.
Encryption Note! A Web browser must support 128 bit encryption in order to be
used with the Configurator. For more information about AES, visit http://
www.nist.gov. This User Guide explains how encryption works with 9200 products in
A. Enabling Encryption Between SPEEDLAN 9200 Routers, page 4-4 and B. Enabling
WEP Security Between a SPEEDMesh-Enabled Client and SPEEDLAN 9200, page 4-4.
Priority Queuing
Despite having two physical interfaces, a SPEEDLAN 9200 router can experience
congestion. That is because the interfaces' bit rates are not matched. Specifically,
packets can ingress (enter) the Ethernet interface faster than they can egress (exit) the
wireless interface. If this occurs briefly, it is called short-term congestion, which can
cause increased packet delay and/or jitter. If congestion lasts too long, it can cause
packet discard ("loss"). Long-term congestion in a SPEEDLAN 9200 will typically only
occur when it receives excessive unthrottled UDP traffic at its Ethernet interface. TCP
traffic will self-throttle, typically experiencing only short-term congestion, if any.
A SPEEDLAN 9200 mitigates short-term congestion by providing priority egress
queuing at its wireless interfaces. With priority queuing, packets may be transmitted in a
different order than they were received. This allows favoring network management,
VoIP and SCADA, over SMTP, ftp, and NNTP (for example).
How does Priority Queuing work? The packets are prioritized into a hierarchy of
queues, based on class of traffic. The highest priority queue packets are serviced first.
When the highest queue is emptied, the next lower queue is serviced. The SPEEDLAN
9200 has four levels of priority queues.
1-5
Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide
Queue 1 (the highest queue serviced) contains "management" traffic (i.e., RIP, Mesh,
K2, SNMP). Queue 2, the next lower queue serviced, contains "real-time" traffic (i.e.,
VOIP, Video, SCADA). Queue 3, the next lower queue serviced, contains "non-real
time interactive" traffic (i.e., HTTP, SSH and Telnet). Queue 4 (the lowest level queue
serviced) contains all traffic that doesn't fit into one of the first three queues.
There are no matching or requirements for this queue; it is simply the default queue if
the packet doesn't qualify for one of the first three queues.
SNMP
The SPEEDLAN 9200 contains a Simple Network Management Protocol (SNMP) Agent
that provides a remote Network Management System (NMS) with read-only ("get")
access to certain configuration and status parameters. For more information, see
SNMP, see SNMP, page 3-26.
Equipment and Hardware
For information about equipment and hardware, see SPEEDLAN 9200 Hardware,
page 2-1.
SPEEDLAN 9200 Mesh Protocol -- How It Works in Mesh Cells
Figure 1-1: SPEEDView illustrating a mesh network (in SPEEDManage suite)
1-6
SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03
SPEEDLAN 9200 routers provide the unique ability to "self-heal" the wireless network as
the topography changes over time, thereby increasing the overall stability and
performance of the network while allowing traffic to reach buildings blocked by
obstructions of line-of-sight.
What is happening in Figure 1-1 on page 1-6?
• You will notice negative numbers next to the routers, or referred to as nodes
on the network diagram. These numbers represent the receive signal strength
(expressed as dBm) for the links in the network diagram.
• The black dots in a mesh network diagram indicate a trace route, which maps
out the current data flow between the selected pair of nodes. A user would
select the trace feature to view the data flow between a node pair (for mesh
networks only).
This illustration also shows that every router in the mesh cell can be heard by
every other router in the cell, except for the blocked link indicating that there is
no signal between those two nodes.
SPEEDView allows you to block traffic over any link in the cell. When you block
a connection, the node pair will not be able to communicate. The advantage
of blocking a connection is verifying that the path can be re-routed for successful connectivity. (This is done using the "Block" feature in SPEEDView. The
broken [or disconnected] link will appear as a red line. This link also appears
when there is no signal between two nodes.)
• SPEEDView can also be used to perform bandwidth, link and ping tests.

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide
Explaining this scenario on the simplest level (using the Mesh protocol as shown in
Figure 1-2 on page 1-7). A can route a packet to B, despite the tree obstruction (block
of trees) within the path. How does this procedure work?
1 A has line-of-sight to C but not to B.
2 C has line-of-sight to A and to B.
The most efficient path in this case is to hop from A to C to B.
Note: No manual programming is required because A automatically detects its
neighboring router (in this case C, and B and detect a clear path to C). Therefore, the
packet is successfully routed around the obstacle between B and A.
This process creates a more scalable, flexible, and extended wireless network (as shown
in Document Changes/Corrections, page 1-11).
SPEEDLAN’s Mesh Cell Architecture
Separate multi-user and residential models (SPEEDLAN 9201 for business and
residential use, as well as the SPEEDLAN 9204 for residential use) are specifically
designed to meet the connectivity demands for everyone from single users to large
corporations. SPEEDLAN 9201 and SPEEDLAN 9204 are mesh units. These models will
communicate with every other mesh router within an unobstructed radius of 1/2 mile
for SPEEDLAN 9201 and 1/4 mile for SPEEDLAN 9204.

SPEEDLAN 9200 User Guide Part # 34357-MNL Rev.03
SPEEDLAN 9200 Mesh Core Components
SPEEDLAN 9200 Mesh protocol includes three central components which are neighbor
discovery, topology updates, and routing.
Neighbor Discovery
Neighbor discovery occurs when each router sends a broadcast "hello" message to
detect those routers to which it has line-of-sight. The "hello" sender acknowledges those
replies, whereupon the sender and the neighboring router add each other to their
respective active neighbor lists. Neighbor discovery protocol messages are sent by each
router on startup and periodically thereafter. The periodic messages are required to
determine when a former neighbor can no longer be reached, whereupon it is removed
from the active neighbor list. Neighbor discovery messages are relatively short and are
sent infrequently enough that they don't constitute significant overhead.
Topology Updates
When a router adds or deletes a neighbor to or from its active neighbor list, it
propagates that information to the rest of the routers in the wireless mesh LAN. Unlike
classic wired routing protocols, topology update notifications are not flooded. Instead
they are sent via a spanning tree, such that each router receives only one notification of
a particular event. (A brief explanation of the spanning tree algorithm is explained in
the note below.) This approach also conserves bandwidth for use in forwarding user
traffic. Since each router knows the topology of the entire wireless LAN, it can
determine the shortest path to each peer router in the wireless LAN.
Note: In short, the spanning tree algorithm enables units to dynamically locate a
subset of the topology that is loop-free. The spanning tree algorithm determines the
best path a unit can use to send a message.

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide
Routing
Routing is simply the act of forwarding a received Internet Protocol (IP) datagram (a
block of data) toward its destination. The router compares the destination IP address to
entries in its routing table. If the destination is a wireless neighbor or a node connected
to the router's wired LAN, the router sends the datagram directly to the destination.
Otherwise, it sends the datagram to another router, which must be on the wired LAN or
be a wireless neighbor.
In wired broadcast LANs, all routers on the LAN can hear each other. Therefore, a
datagram only passes through a router when it is moving from one LAN to another LAN
along the path to its destination. In a mesh wireless LAN, not all routers can hear each
other. Therefore, a router within a wireless LAN may forward a datagram to a neighbor
router within the same wireless LAN, in order to send the datagram toward its
destination. For each datagram, the routing algorithm minimizes the number of router-
to-router hops within the wireless LAN, thereby also conserving bandwidth for other

The SPEEDLAN 9200 outperforms other routers because the SPEEDLAN 9200 routing
table broadcasts only the information that changed, such as when new routes are
added or old routes are removed from the network. This information is sent to the
router's immediate neighbors along the most efficient path to the end destination. This
process helps conserve bandwidth. If an existing path is modified in some way, by the
addition or deletion of a router, a SPEEDLAN 9200 using the Mesh protocol can
monitor its routing table to decide if a secondary path should be taken. One could call
this a "self-healing" network, which means it finds a secondary route through the
network without manually reprogramming the routers.

Hardware Overview
The SPEEDLAN 9200 offers all the equipment you need to meet your connectivity
requirements:
• SPEEDLAN 9201: A router used in a non-line-of-sight pico cell (using the
Mesh protocol). This router contains an integrated 8 dBi, omni antenna (for
2.4 GHz only) which is directly attached on the top. You do not need an
additional external antenna. The parameters are configured with the Mesh
protocol in the SPEEDLAN 9200 Configurator. This type of self-healing Mesh
topology process helps you reach buildings that do not have a clear line-ofsight back to a base station without the possibility of interference from hidden
transmitters. For more information on this topic, see SPEEDLAN 9200 Mesh
Protocol -- How It Works in Mesh Cells, page 1-6.
2-4
• SPEEDLAN 9202: This model can be configured as Customer Premise
Equipment (CPE) at one end of the point-to-point or point-to-multipoint link. It
can be used with a 2.4GHz or 5GHz external antenna.
• SPEEDLAN 9203: This model is pre-configured as a base station but can be
reconfigured to function as a CPE router or as one end of a point-to-point or
point-to-multipoint link. It can be used with a 2.4GHz or 5GHz external
antenna.
• SPEEDLAN 9204: This model provides the same functionality as a SPEEDLAN
9201, but it uses an integrated 5 dBi omni (for 2.4GHz only). The SPEEDLAN
9204 is intended for more densely populated cells.
• SPEEDLAN 9205: This is similar to the SPEEDLAN 9202, but can be used only
in 2.4GHz and 5GHz mesh-only applications.

The SPEEDLAN 9200 is housed in a waterproof, cast enclosure that mounts outside the
building, on a mast, or tower. The SPEEDLAN 9200 allows up to 300’ of specialized,
outdoor Ethernet cable to be used between the LAN and the RF device, without loss of
any radio signal. This increases the effective wireless link distance and reduces or even
eliminates the need for an amplifier.
Tips for Antenna Alignment
You are encouraged to use the transmit power test during installation if you have a
spectrum analyzer or power meter to measure the output for the antenna alignment.
For more information, see the SPEEDManage User Guide. The SPEEDSignal
application will also help installers align or position antennas on SPEEDLAN 9200
units.

Installation Steps for the SPEEDLAN 9201/SPEEDLAN 9204
To install your SPEEDLAN 9201/SPEEDLAN 9204, follow the steps below:
Step 1: Mounting the SPEEDLAN 9201/SPEEDLAN 9204
This router will have an omni directly attached. No additional steps are needed for this
step. Go to Step 2.
Step 2: Mounting the SPEEDLAN 9201/SPEEDLAN 9204 on the Pole
• Pole Mount: Attach the router to the mounting pole using the two V-bolted
clamps and aluminum bracket, one on top of the router and the other on the
bottom of the router. Make sure you tighten the nuts for the clamps securely to
prevent shifting of the router after antenna alignment.
Step 3: Running the Cabling
1 Run outdoor CAT5 cable (from bottom of router) down to junction box located
inside the building.
2 Secure grounding wire by running this wire to a suitable "earth" ground and
fasten it securely in place. See the installation diagram following
these directions.
3 Install proper indoor ground plug into the junction box. Connect the outdoor
CAT5 Ethernet to the "radio" jack. Connect the LAN Ethernet cable to the "LAN"
jack of the junction box. Install the power supply DC connector to the junction
box. Plug the external power supply into the wall outlet.
(The VAC power outlet’s input voltage of this universal adapter can vary from
100 to 250 VAC.) Connect the DC output of the adapter to DC jack on the
indoor junction box.

Part # 34357-MNL Rev.03 SPEEDLAN 9200 User Guide
4 Connect the wireless SPEEDLAN 9201/SPEEDLAN 9204 to the customer's
Ethernet LAN or PC by connecting the RJ-45 plug on a standard Ethernet
CAT5 cable to the RJ-45 port connector, marked as "LAN" on indoor junction
box. Connect the other end of the Ethernet CAT5 cable to your Ethernet hub,
switch or router.
Important Note: Waterproofing the External Connectors!
Make sure you waterproof all the connectors, as follows: Apply two layers of electrical
tape to the connector (covering three inches of cable past the connector), and leave
approximately 3 inches of cable exposed on either side of the connector. An alternative
is to begin at the lowest point, so the tape overlaps from bottom to top creating a
shingled effect. (This creates an effective barrier against runoff.) Apply this "shingle
effect" to each layer of the sealing process. Then, apply one layer of insulation putty
over the top of the electrical tape, and leave at least one inch of the cable jacket to
ensure a good seal. Do not stretch the putty, as this causes thinning and reduces the
effectiveness of a good seal. Finally, apply five layers of electrical tape over the
insulation putty and extend at least one (1) inch past the putty. This is the most
important step in a creating a watertight seal. Make sure that there are no wrinkles in
the tape, and the final wrap must be completed from bottom to top.
