Coverage
T811-CM Omni Antenna
Coverage
The T811-CM includes internal 5GHz and 2.4GHz omnidirectional antennas, and is equipped with
a DOCSIS 3.1 cable modem.
The T811-CMs are best deployed where internal-antenna lateral beamforming can provide the
greatest reach and throughput to a wide coverage area, and provide the greatest distance
between APs in a connecting device. See Figure 3 for internal-antenna coverage patterns, and see
Figure 4 for a typical mesh coverage pattern between a T811-CM root AP and a 7782 non-root AP.

Powering Options
Powering Options
The T811-CM supports AC power over cable (POC). 60 to 90 VAC POC is used when the T811-CM is
powered via an F-type coaxial cable connected to the HFC cable plant.
Performing a Site Survey
Perform a site survey to determine the optimal T811-CM placement for maximum range, coverage,
and network performance. Ruckus Wireless Support can supply site survey best practices
information.
The location and orientation that you choose for the T811-CM play a critical role in the
performance of your wireless network. In general, Ruckus Wireless recommends installing the
T811-CM away from obstructions and sources of interference and ensuring that the AP’s best
coverage zone is pointing in the general direction of its wireless clients or associated bridge units
as described in T811-CM Omni Antenna Coverage.
When performing a site survey, consider the following factors:
• Data rates: Range is generally inversely proportional to data rates. The maximum radio range is
achieved at the lowest workable data rate. Higher data rates are generally achieved at closer
distances.
• Antenna type and placement: Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, radio range is increased by mounting the radio higher off of the ground
with the AP oriented so that the dome is tilted down. (For recommended orientation examples,
refer to T811-CM Omni Antenna Coverage.)
• Physical environment: Clear or open areas provide better radio range than crowded or filled areas.
The less cluttered the operating environment, the greater the wireless range.
• Obstructions, building materials, and sources of interference: Physical obstructions, such as
concrete pillars, steel beams, buildings and trees, can block or hinder wireless communication.
Avoid installing the T811-CM in an environment where there is an obstruction between sending
and receiving devices. A number of machines and electronic devices that emit radio waves –
cranes, wireless phones, microwave ovens, and satellite dishes – interfere with and block wireless
signals. Building materials used in construction also influence radio signal penetration. For
example, drywall construction permits greater range than concrete blocks.
• Mounting: The T811-CM is designed to clamp onto a 1/4” to 3/8” (6.35mm to 10mm) support
wire. The hangers allow a 2” bundle of cables between the support wire and the T811-CM.
• Power and backhaul connections: The T811-CM needs a backhaul connection to the CMTS
and it needs to be close enough to an AC power injector on the CATV cable to assure that it is
able to pull 60-90VAC. If not, then another power injector must be installed closer to the T811CM. If SFP backhaul is used, POC will still be used for delivering power over the cable, even if
the data is transmitted over the SFP fiber cable.
When you are finished planning the installation, continue with Installing the T811-CM.
Positioning the GPS Antenna
The T811-CM AP includes an internal GPS antenna. If the AP is to be used with the optional
GPS feature enabled, then the GPS antenna must be mounted outdoors and have as clear
a view of the sky as possible (as close as possible to 360 degrees, and with no obstructing
trees or buildings). The GPS antenna must not be installed where it can be covered with
T811-CM AP Installation Guide, 800-71436-001 Rev A

Planning the T811-CM Installation
Powering Options
snow buildup to avoid attenuating the GPS signal. These requirements must be met to
ensure that the GPS module can obtain lock and provide accurate GPS time and position.
If the GPS antenna has less than a clear 360-degree view of the sky, then the GPS module
may experience degraded performance.

LED Startup Sequence (CM Backhaul)
The startup sequence from factory default state to operational state is as follows:
1. At power on, the Power LED is red, then blinking green during bootup.
2. CM DS LED blinks while finding CM downstream link, then solid once complete.
3. CM US LED blinks while finding CM upstream link, then solid once complete.
4. Online LED blinks while getting new config from CMTS, and solid once configuration is
complete.
5. Power LED is solid green once an IP address is received.
6. Once the AP is approved on the controller, the DIR LED starts blinking, indicating firmware
downloading.
Note: If the AP was preconfigured at the factory and does not need a firmware upgrade, this
step is skipped.
7. Once firmware upgrade is complete, the AP reboots and the Power LED turns red, then
blinking green, then solid green once reboot is complete.
8. AIR, 2.4 GHz and 5 GHz LEDs are the same as other Ruckus APs: Amber when SSID is up,
green when clients connected to the radio. The AIR LED indicates Mesh AP upstream
connectivity; therefore it will not generally be lit on a cable modem AP, whose backhaul should
be the cable modem rather than a mesh link.

Installing the T811-CM
Deploying the T811-CM
Deploying the T811-CM
In this section, you will mount the T811-CM in its final mounting location. Perform the following:
• Mounting the T811-CM
• Earth Grounding the T811-CM
• Installing the Cable Power Tap
• Powering the T811-CM with POC
• Checking the T811-CM Signal Level with an RF Power Meter (Optional)
• Configuring the T811-CM for the First Time (Optional)
Mounting the T811-CM
To mount the T811-CM assembly on a cable strand, you need to secure the cable clamps that are
attached to the strand interface to the cable strand.
1 Slightly loosen the nuts that fasten the two cable clamps to the strand interface, enough for the
strand support cable to fit into the cable clamps.
2 Place the cable clamps on the strand support cable.
3 Tighten the two cable clamp nuts to 22 to 27N.m (16 to 20 ft-lbs) to secure the mounting.
You have mounted the T811-CM. Continue with Earth Grounding the T811-CM.

Installing the T811-CM
Deploying the T811-CM
Earth Grounding the T811-CM
The cable strand is usually earth-grounded, and mounting the T811-CM on the cable strand earth
grounds the T811-CM chassis as well; if this is the case, skip this procedure and continue with
Installing the Cable Power Tap.
CAUTION! Be sure that earth grounding is available and that it meets local and national electrical
codes. For additional lightning protection, use lightning rods and lightning arrestors.
If the cable strand is not earth-grounded, then continue with the following:
1 The color coding of ground wires varies by region. Before completing this step, check your local
wiring standards for guidance.
2 Using the factory-supplied ground screw and washers, use the factory-supplied earth ground
wire with ring terminal to connect a good earth ground to the T811-CM using the chassis
ground screw shown in Figure 5.
CAUTION! The T811-CM includes one 12mm stainless steel M6x1 earth ground screw with split
lock and flat washers. Make sure that any replacement screw is no longer than 12mm. If a screw is
longer than 12mm, it can damage the T811-CM chassis.
You have earth-grounded the T811-CM. Continue with Installing the Cable Power Tap.

Installing the T811-CM
Deploying the T811-CM
Installing the Cable Power Tap
The CATV coaxial cable used in the field deployment must have 60 to 90 VAC power multiplexed
with the RF signal on the coaxial cable, since the T811-CM Connector B is used for both electrical
power and the RF signal.
Ruckus Wireless recommends installing a cable power tap (Antronix MGT2000-SDPE tap, or
equivalent) close to the T811-CM. Refer to the manufacturer’s instructions to mount the cable power
tap on the coaxial cable. Figure 7 shows a typical cable power tap and connection to the CM
using an RG6 quad shield cable. Table 4 describes the elements in Figure 7.
NOTE If the F connector on the T811-CM is damaged, then refer to Appendix C: Replacing the F
Connector Adapter.
1 Use a customer-supplied cable, connect any port on the cable power tap to the F connector on
the T811-CM.
2 Using a wrench, tighten the cable F connectors to 3.4N.m or 30in-lbs.

Installing the T811-CM
Deploying the T811-CM
Powering the T811-CM with POC
60 to 90 VAC POC is used when the T811-CM is mounted on a cable strand and powered via an Ftype coaxial cable connected to the HFC cable plant.
1 Remove the power jumper from the power tap to remove AC power out of the power tap.
2 Insert the F-type coaxial cable that is connected to the HFC cable plant to the F-type connector
on the T811-CM. Power is supplied through a power passing tap on the CATV coax. The tap is
connected to F-type connector on the T811-CM as shown in Figure 5.
3 Finger tighten the coaxial cable connector and then tighten to 3.4N.m (30in-lbs).
4 Plug the power jumper back into the power tap to restore AC power out of the power tap.
5 When the T811-CM receives power, its LEDs flash on and off as it goes through a power-on self
test and then receives its AP and CM configurations from the cable operator.
NOTE Normally, the T811-CM receives its AP and CM configurations from the cable operator.
This means that the installer does not need to manually configure either the AP or the CM part of the
T811-CM.
6 Wait until the T811-CM PWR, CM DS, CM US, and ONLINE LEDs stop flashing and then remain
on.

Operating and Troubleshooting the T811-CM
How Radio Frequency Scanning Works
How Radio Frequency Scanning Works
The following steps describe how a DOCSIS-compliant T811-CM performs radio frequency
scanning:
1 Looks at the last “known good channel” (repeat this every 64 channel checks).
2 Checks the sixteen last known frequencies (repeat this every 32 channel checks).
3 Scans STD standard channels (where the center of the channel is an integer spaced by 6MHz),
first [from 93MHz to 999MHz - 152 channels]).
4 Scans the harmonically related carrier (HRC) channels, which moves the channels 1.25MHz off
the standard frequencies so the video carriers are all related by 6MHz [from 91.75 to 997.5MHz-152 channels].
A complete frequency scan requires approximately 469 channel checks. Since each channel takes
about 0.6 seconds, a full scan is done every 281 seconds (a little under 5 minutes).
NOTE The scanning of generic DOCSIS channels is required the first time the T811-CM connects
to an MSO. After the initial scan, the T811-CM is able to retrieve the local country frequency plan
without a complete scan during its normal operation.

What to Do Next
The following are some of the post-installation tasks that Ruckus Wireless recommends. Refer to the
Ruckus Wireless Outdoor Access Point User Guide for more information on configuring and managing
the AP.
Changing the Administrative Password
Management access to the Web interface of the AP is controlled through administrative user name
and password. As soon as you complete the AP setup, make sure you log on to the AP’s Web
interface and change the default administrative user name and password. This will help prevent
unauthorized users from logging in to the AP’s Web interface and changing the AP settings to
compromise your network.
Configuring the Security Settings
Unlike wired networks, anyone with a compatible wireless adapter can receive wireless data
transmissions from your network. To prevent unauthorized users from entering your wireless network
and accessing your computers and files, Ruckus Wireless strongly recommends enabling and
configuring wireless security on the AP. The AP supports several types of encryption and authentication methods to help prevent unauthorized access to your wireless network.
Configuring Advanced Settings and Features
The AP has been configured for basic operation. However, the Ruckus Wireless AP supports many
advanced settings and features. Refer to the Ruckus Wireless Outdoor Access Point User Guide for
instructions on how to configure the advanced setting and feature parameters.
