About This Installation Guide 1
This Installation Guide provides information on how to set up the Ruckus Wireless T811-CM (model
901-T811-CM-US31) strand mount access point (AP) with integrated cable modem (CM) on your
network.
Topics covered in this guide include basic configuration, operation and mounting. The rest
of this
document refers to the strand mount access point with integrated cable modem as the
T811-CM.
This guide is intended for use by those installing and configuring network equipment. Consequently,
it assumes a basic working knowledge of local area networking, cable modem configuration, wireless
networking, and wireless devices.

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.

Planning the T811-CM Installation
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 T811-
CM. 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.

Safety Information
Safety Information
WARNING! Only trained and qualified installers should be allowed to install, replace, or service this
equipment.
The professional installer is responsible for the proper installation and configuration of this AP. The
AP installation must comply with local regulatory requirements, especially with those regulating
operation near military and/or weather radar systems.
WARNING! Installation of this equipment must comply with local and national electrical codes.
WARNING! Ruckus Wireless strongly recommends that you wear eye protection before mounting
the AP.
CAUTION! Make sure that you form a 80mm - 130mm (3”-5”) drip loop in any cable that is attached
to the AP or other equipment. This will prevent water from running along the cable and entering the
AP or other equipment.
CAUTION! Be sure that grounding is available and that it meets local and national electrical codes.
For additional lightning protection, use lightning rods and lightning arrestors.
CAUTION! Make sure that proper lightning surge protection precautions are taken according to
local electrical code.
