FCC Regulatory Compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manuals, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
Modifications to this product not expressly approved by Proxim, Inc., could void the FCC approval and the user's
right to operate the product.
The Stratum is intended for point-to-point operations over an unobstructed line-of-sight path.
This equipment is authorized for use by the FCC, under the United States Code of Federal Regulations Title 47 Part
15 Subpart E – Unlicensed National Information Infrastructure Devices (UNII).
To comply with FCC rules for UNII devices:
1. The equipment must be installed in accordance with CFR 47 Section 15.407 (a) (3) which states: “The
operator of the U-NII device, or if the equipment is professionally installed, the installer, is responsible for ensuring
that systems employing high gain directional antennas are used exclusively for fixed, point-to-point operations.”
2. The installer must ensure that the unit is properly installed in compliance with the FCC’s guidelines for
maximum permissible radio frequency exposure as outlined in CFR 47 Section 1.1307(b)(1), preventing excess
exposure to all persons. The installed radiating device should be inaccessible to unauthorized personnel. The
installed unit should be positioned to guarantee no direct continuous exposure to people within 5 feet of the antenna.
During installation, the installer should use caution to avoid excess exposure to directed antenna radiation within 3
feet of the front of the antenna.
3. The unit is normally provided with an integral flat panel antenna for both the “A” end (5.3 GHz transmitter) and
the “B” end (5.775 GHz transmitter) of the point-to-point link. For extended range applications, the unit at the “B”
end may be provided with a connection for an external parabolic antenna instead of an integral flat panel antenna.
When deployed with an external antenna, the unit must be professionally installed to comply with CFR 47
Section 15.203. Only antennas with gain less than 40 dBi are authorized for use with the “B” unit. The antenna
gain improvement at the “B” end of the link aids both directions of the link.

Industry Canada Regulatory Compliance
This device complies with Industry Canada specification RSS-210 for “Low Power License-Exempt Radio
Communication Devices,” Section 6.2.2 (o1), “Local Area Network Devices.”
The Stratum is designed for point-to-point communications and operates within the bands 5250-5350 MHz and
5725-5825 MHz.
Users should take note that high power radars are allocated as primary users (meaning they have priority) of 5250-
5350 MHz and 5650-5850 MHz and these radars could cause interference and/or damage to LELAN devices.
Users should also take note of the maximum antenna gain permitted to comply with restrictions for those bands:
5250-5350 MHz
“The maximum transmitter power shall not exceed 250 mW or 11 + 10 Log B dBm, whichever power is less. The
power spectral density shall not exceed 11 dBm in any 1.0 MHz band. The maximum EIRP shall not exceed 1.0 watt
or 17 + 10 Log B dBm, whichever power is less. B is the 99% power bandwidth in MHz.”
The Stratum ODU-A transmits between 5250-5350 MHz. The transmit power is +1 dBm. The integral flat panel
antenna gain is 26 dBi. The EIRP is 27 dBm and complies with the requirement above.
5725-5825 MHz
“Fixed point-to-point devices for this band are permitted up to 200 watts EIRP by employing higher gain antennas,
but not higher transmitter output powers. Point-to-multipoint systems, omni-directional applications and multiple
co-located transmitters transmitting the same information are prohibited under this high EIRP category.”
The Stratum ODU-B transmits between 5725-5825 MHz. The transmit power is +1 dBm. The integral flat panel
antenna gain is 26 dBi. The EIRP is 27 dBm and complies with the requirement above.
The Stratum ODU-B-EXT transmits between 5725-5825 MHz. The transmit power is +1 dBm. External parabolic
antennas with gain up to 52 dBi will comply with the requirement above.

Safety Warning
Before aiming the antenna or working near the antenna, read this entire manual and follow the instructions
carefully.
DO NOT STAND IN FRONT OF THE ANTENNA WHILE POWER IS ON.
Be sure to provide adequate grounding and lightning protection. Do not install the Outdoor Unit
near overhead electrical wires.
This unit is intended for point-to-point operation over an unobstructed line-of-sight path. It is the responsibility of
the installer to ensure the unit is properly installed in compliance with the FCC’s guidelines for maximum
permissible radio frequency exposure outlined in CFR 47 Section 1.1307(b)(1), preventing excess exposure to all
persons. The installed radiating device should be inaccessible to unauthorized personnel. The installed unit should
be positioned to guarantee no direct continuous exposure to people within 5 feet of the antenna. During installation
use caution to avoid excess exposures to directed antenna radiation within 3 feet of the front of the antenna.
The transmit power output from the Stratum is less than 0.8 milliwatts. However, after the gain of the standard 18-
inch flat panel antenna is added, the Effective Radiated Power is approximately 0.5 watts. Microwave radiation can
cause tissue heating, potentially affecting the eyes, and causing permanent damage to vision.

Chapter 1: Introduction
The Stratum is a wireless Ethernet bridge designed to deliver dedicated full duplex 20 Mbps or 100 Mbps
connectivity with fiber reliability. The Stratum transports all Ethernet traffic types in addition to two T1 channels.
With full duplex Ethernet bridging and two T1 links for applications such as voice traffic, Stratum satisfies many
short haul, high capacity communications needs.
In contrast to millimeter wave equipment, Stratum delivers high throughput with none of the negative factors
associated with millimeter waves. There’s no worry about rain fades or poor bit error rates. Stratum links perform
as well as fiber, at a fraction of the cost and with far less time to deploy.
Features
• Full duplex 20 Mbps or 100 Mbps LAN bridging
• Dual T1 transport for TDM voice and data traffic without impact to LAN performance
• Unlicensed U-NII band operation allows fast deployment and is immune to weather fades
• Fiber class performance
• Fully SNMP managed using industry standard platforms such as HP OpenView
Product Overview
Proxim’s Stratum is the first product operating in the U-NII bands to merge high capacity voice and data with ease
of installation and operation. Stratum incorporates a MAC layer Ethernet bridge for high capacity bridging of all
Ethernet traffic types, including IP and Voice-over-IP. With auto-negotiation for 10/100 Ethernet, full or half
duplex LAN support combined with 802.1d Spanning Tree functionality, Stratum requires very little in the way of
initial configuration. In addition to the 20 Mbps or 100 Mbps full duplex bridging capabilities, Stratum includes two
DSX-1 interfaces for transport of voice between digital PBXs or other T1 traffic. The DSX-1 interfaces operate
equally well for channelized or unchannelized T1 applications.
Operating at distances of up to 7 miles, Stratum far outperforms ISM band radios and Infrared devices. Also,
Stratum is easily managed using SNMP or the native HTML Graphical User Interface.

Chapter 1: Introduction •

•8 Stratum Installation and Maintenance Guide
Rapid Deployment
Stratum operates in the newly allocated U-NII bands, with no FCC licensing requirements. Unlicensed band
operation removes the waiting time involved with frequency coordination and license approval. Stratum can be
deployed immediately in contrast with up to six weeks delay for deployment of licensed band products.
Additionally, if you need to move the link, the Stratum antennas may be relocated without applying for license
changes.
Fiber Class Performance
For years, fiber has been the performance standard for communications media. Today, Proxim brings the
outstanding performance of fiber to wireless communications. Stratum employs a concatenated Reed-Solomon
(t=16) Forward Error Correction and Viterbi convolutional decoding to provide the highest degree of error
correction, which is transparent to the user. Because Stratum operates in the 5 GHz U-NII bands, rain, fog and other
weather conditions do not adversely affect operation.
100 + 3 Mbps or 20 + 3 Mbps Full Duplex Throughput
The Stratum 100 delivers 100 Mbps full duplex throughput for transport of Ethernet traffic, so the wireless link is no
longer a bottleneck on the network. The Stratum 20 provides all of the features of the Stratum 100 but delivers 20
Mbps full duplex throughput and is ideal for applications requiring less bandwidth.
In addition to the 100 Mbps or 20 Mbps wireless connectivity available for LAN traffic, Stratum incorporates two
DSX-1 interfaces for point-to-point transport of T1 traffic, such as digital voice. Each T1 operates at full speed and
does not share bandwidth with the LAN traffic; so all data streams receive the maximum throughput with the lowest
latency. Stratum’s broadband capabilities make it the ideal choice for bandwidth hungry applications like multi-
Megabit Internet access, Voice-over-IP, and real-time video and imaging.
Installation, Maintenance, Management, and Monitoring
Designed for installation and maintenance by IT professionals, one or two qualified individuals can install a Stratum
link in a matter of hours. The Stratum’s “Aiming LED” allows the installer to aim the antennas without using
costly test equipment.
Stratum requires no maintenance or calibration for the life of the product. Software upgrades to the Outdoor Unit
are downloaded from the Indoor Unit via the IDU-ODU fiber interface.
SNMP or TELNET allow easy day-to-day monitoring, and you may manage the Stratum from any standard SNMP
manager such as OpenView or SunNet Manager™. The Industry standard MIB II and a Proxim Enterprise MIB
allow full access to parameters for SNMP management. Stratum can send traps to multiple hosts on networks where
management is distributed among more than one computer.
An integrated menu-driven configuration and management tool allows the operator to review the system parameters
at a glance and to access packet and radio statistics for both ends of the link from a single interface. An integrated
HTML interface is also standard and allows password protection to prevent unauthorized access.

Standard Configuration
The Stratum consists of three units:
• The Indoor Unit (IDU) is a rack-mountable unit that contains the electronic bridging components. The
IDU can be installed in any convenient climate-controlled location within a building. The IDU must be
powered from an 110V or 220V AC source.
• The Outdoor Unit (ODU) is a pole-mountable weather tight unit which contains the RF components and
includes an 18" x 18" x ¾" flat panel antenna. An ODU-A transmits in the mid-UNII band, centered at
5287 MHz. An ODU-B transmits in the upper-UNII band centered at 5782 MHz. One ODU-A and one
ODU-B are required for a Stratum link.
• The Alignment Mounting Bracket (AMB) is a galvanized steel bracket used to mount the ODU to a pole
of 1.9 to 3.5 inch diameter. The AMB can be adjusted on the pole in both vertical and horizontal axes to
align the flat panel antenna along the line-of-sight path.
The IDU and ODU must be interconnected via two multi-mode fiber cables, one for transmit, one for receive. A
shielded two-conductor cable (with drain) is required to supply DC power from the IDU to the ODU. The IDU will
supply adequate DC power over a 1000-foot span to the ODU using 18 AWG wire pair.
Figure 1 shows a typical link bridging network traffic between two buildings. The two ODUs in the diagram are
mounted on the roofs of two adjacent buildings and the associated IDUs are located inside these buildings.

Sample Stratum Installation
The standard Stratum link is supplied with a pair of high-performance, flat panel phased-array antennas to establish
a connection over a distance of up to 4 miles. The small antenna size (18"x18"x3/4") and light-weight outdoor unit
allow building-top installations to use a cost effective tripod or parapet-braced pole mount. Alternatively, a Stratum
link can establish a connection over a distance of up to 7 miles using a high-gain parabolic antenna at one end.
Optional External Antenna Configurations
For extended range applications, the ODU at the “B” end of the Stratum link may be supplied with an “N”
connector for an external parabolic antenna instead of the integral flat panel antenna. The ODU-B-EXT allows the
Stratum to utilize industry standard parabolic antennas. Parabolic antennas are commercially available in 2, 4, and
6-foot diameters that are characterized for both the mid and upper U-NII frequency bands. Use of such antennas can
increase overall link system gain to achieve connectivity over a distance of up to 7 miles with 99.99% Availability.

Installation Preparation: The Path Survey & Cable
Installation
Before beginning installation, you should complete path and site surveys for the link, including line-of-sight path
planning, antenna supports, and pre-installation preparation. The path survey should also specify the expected
signal strength between the two antennas. Proxim strongly recommends that a qualified radio engineer perform
the path survey. The procedure to perform a path survey is beyond the scope of this manual. If you have questions
about or problems with the path survey, contact your reseller or Proxim Technical Support.
Assembling Tools and Cables Before You Begin
The following tools are needed during installation:
For Installing the IDUs and ODUs
• 1/2" socket wrench
• 1/8" slotted screwdriver
• Assorted hand tools
• #2 Phillips screwdriver
• Digital multi-meter
• Torque wrench (if you intend to change antenna polarity)
• PC or laptop running HyperTerminal, or an equivalent VT-100 terminal emulation program. The PC or

Step 1. Installing and Mounting the ODUs
The following instructions describe how to assemble and mount a single ODU with integrated flat panel antenna.
Refer to the end of this section for information on how to mount the ODU-B-EXT using a parabolic antenna.
Remove the ODU, pre-assembled Antenna Mount, and Accessory Kit from their shipping cartons. Save all packing
materials in case you need them later.
Using the foam packing material to protect the painted surfaces of the antenna, carefully place the ODU on the
packing foam with the antenna facing down.
Set aside the accessory kit. Use this hardware to attach the antenna mount to the ODU, and to attach the complete
ODU to a supporting mast.
Note: The ODU and antenna are factory weather-sealed. DO NOT DISASSEMBLE THE ODU OR
REMOVE THE ANTENNA – THIS WILL VOID THE WARRANTY.
The ODU’s connectors are shown in Figure 2 below.
