Introduction
EkoMini is quick and easy to install, using a minimum set of common tools. This section will
provide the basic steps to performing the installation of EkoMini. Please read complete
instructions before beginning assembly.
Description
The EkoMini is a bi-directional amplifier unit and was designed to provide enhanced RF
coverage for wireless systems in small facilities. Usage includes providing coverage in retail
stores, offices, warehouses, restaurants, etc.
The EkoMini is housed in an indoor mountable enclosure.
The EkoMini supports most system protocols including CDMA, GSM/PCS1900 and TDMA and
is available in models that cover all licensed 1.9 GHz PCS bands A through F, ESMR/SMR 806-
866 MHz and Cellular 821 to 894 MHz. Band selective filtering in both uplink and downlink
signal paths is accomplished with down conversion to an intermediate frequency and SAW
filtering to provide maximum selectivity from out of band carriers.
The EkoMini features auto set-up, lightweight compact enclosure, optional remote alarming,
excellent electrical specifications, high reliability and cost-effective pricing.

IM 610179-1, Rev 02
08/25/06 Page 6
Functionality
In order to function properly, during initial set-up the downlink signal must be presented to the
EkoMini. Without the downlink signal, the unit will not operate properly.
The EkoMini is capable of automatically adjusting its own signal gain levels up to the maximum
output power levels. The EkoMini detects the downlink output power and adjusts the level for
20-dBm composite output power and continues to monitor and reset the gain as required for
proper system performance. For example, when a CDMA protocol system is being amplified,
there could be an error in set-up initially resulting from only pilot sync, and paging Walsh codes
being present on the RF carrier. The EkoMini will reduce the system gain until no signal is
received that will exceed the output power set- ting. This prevents the EkoMini from setting up
to a higher power level than actually desired if all of the Walsh codes were present. The gain
does not continually change to maintain an output power of 20 dBm (AGC) since this would
defeat and fight the benefits of power control in the system. The user may reduce or limit the
power output level by adjusting the peak power limit as described below. The user peak power
switches will set the unit's output power up to 14 dB below the maximum power output of 20
dBm; the user interface to control this feature is the peak power switches.
The EkoMini has 30 dB of gain control in the uplink and downlink signal paths. This gain is
controlled by two methods. Up to 14 dB can be con- trolled by adjusting the user peak limit
switches located behind an access plate on the side of the unit to limit the maximum output
power level. The uplink and downlink attenuators are controlled by the internal microprocessor
to adjust the maximum gain of the unit for both paths. The uplink and downlink signal paths are
adjusted to the same setting by the microprocessor unless the user offsets, reduces the gain in
the uplink signal path. The user has control to reduce the uplink gain by 6 dB, this can be used
to balance the uplink and downlink paths as well as reduce contribution of noise to the base
station receivers.
The EkoMini has a total of 30 dB of gain control in the uplink and downlink signal paths, which is
controlled by the microprocessor. The microprocessor monitors the uplink and downlink
detected signal levels and adjusts the gain to prevent overdriving the linear power amplifier
circuits.
The EkoMini monitors the downlink-detected signal and adjusts the gain to achieve rated output
power, +20 dBm. The uplink attenuation is adjusted by the microprocessor to the same gain
level. Path loss is normally equal in both directions. The microprocessor continues to monitor
the detected out- put power on both paths to prevent overdrive. Should the downlink de- tected
power increase above the desired level; the processor will reduce the gain in both uplink and
downlink paths. A subscriber unit getting very close to the rerad antenna, may cause uplink
signal overdrive. The processor will temporarily reduce the gain in the uplink (reverse) path
when uplink signal overdrive is sensed, which will reduce the coverage during this condition.
Proper placement of the rerad antenna will reduce the occurrence of this condition.
Protocol Selection
To insure proper RF power output the proper protocol must be selected this insures the
software will properly distinguish the detected RF power level. CDMA is the only protocol that
requires a different look up table/RF calibration.

IM 610179-1, Rev 02
08/25/06 Page 7
Band Selection
All Frequency Bands must be factory set and cannot be altered in the field. If you desire your
EkoMini to be set to a different Frequency Band than originally ordered, it must be returned to
the factory. Please contact Customer Service.
System Set Up Instructions:
- During initial set-up, downlink signal must be presented to the unit.
- Apply Power
- Log in to GUI via Web browser
- Set Up Peak Power and Uplink Offset
- Restart Unit Using Setup Screen.

EkoMini with IP Modem
QTY Description
1 EkoMini
1 Manual
1 Test Data, Factory
Mounting
EkoMini is designed for optimum use as an in-door repeater. The housing is not weather
resistant and the automatic set up procedure assumes sufficient isolation between antennas is
assured. When the donor antenna is mounted outside and the rerad/server antenna is mounted
inside of a building isolation is assured to be adequate.
Antennas mounted outside shall comply with Article 810 of the National Electrical Code,
ANSI/NFPA 70, specifically, clearances from power and lightning conductors, mounting, and, if
necessary, groundings.
Since the EkoMini has a minimum gain of 40 dB, isolation of at least 55 dB must be obtained
between the donor and the rerad antenna. Should adequate isolation not be obtained an
oscillation could occur which could cause damage to the unit.
•Connect coaxial cables to the Donor and Rerad ports.
•Connect primary power module to unit
For EkoMini with IP Modem connect AC Power to AC Power Input on
Modem Module and connect 9VDC Output of Modem Module to EkoMini
DC Input.
Installation

IM 610179-1, Rev 02
08/25/06 Page 9
This unit will be installed by a professional installer using the appropriate anchors, etc. to
support a minimum of 30 lbs(actual weight of unit is 10 lbs) with four(4) #8 screws a minimum of
1 ¼ inch in length(not provided with unit) for the surface where the unit is being mounted in the
orientation shown located within 2.95 meters of the unit.
Standard hand/power tools possessed by any qualified installer are adequate for both installing
and removing the unit.
The power supply cord must not be attached to the building surface nor run through walls,
ceilings, floors, and similar openings in the building structure. The power supply cord must be
inserted in a standard receptacle.
CAUTION !
DOUBLE POLE / NEUTRAL FUSING
Select Mounting location of Donor directional antenna and orient toward the base station to
maximize signal level. For best performance this should be line of sight between the Donor
antenna and the base station antenna.
Alarms
All alarms are considered major since there are no field replaceable modules in the unit. All
alarms are indicated locally and immediately by the Alarm LED indicator blinking red. Once the
Alarm State has existed for 5 minutes, the Alarm LED will have a constant red indication.
Certain problems will result in the unit automatically shutting down after 5 minutes of sensed
failure. This is done by disabling the RF output stages in both the uplink and downlink signal
paths. Removing DC power from the unit for a period of 30 seconds or longer will reset the auto
shut down.

No RF Uplink Detected; this is a normal state for the uplink RF path. The normal levels of RF
received and amplified from the subscriber unit may be below the -10 dBm detectable level. A
quick check can be made by getting within a few feet of the Rerad Antenna, while watching the
Uplink RF indicator.
Primary Power
The EkoMini with IP Modem operates on AC input voltages of 100 to 240VAC only.
Donor Antenna
This input/output is connected to an antenna, which is directed at the desired cell site.
Rerad Antenna
This input/output is connected to an antenna, which is mounted in the desired area to be
covered. The antenna should be mounted at a location where adequate coverage is provided
for the area desired while EkoMinimizing the potential of subscriber units normally operating
close enough to overdrive the unit.
Serial Number
Each unit has a unique electronic serial number. This number is displayed on the decal on the
unit and is also displayed with the history log when using the modem interconnect.
Installation:
Note 1: Only qualified technicians should perform Installation and system set up. The user is
cautioned that modification or changes to this device not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
Note 2: Manufacturer's rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5
dBm, especially where the output signal is re-radiated and can cause interference to the

adjacent band users. This power reduction is to be determined by means of input power or gain
reduction and not by an attenuator at the output device.
AC Systems (EkoMini with IP Modem)
The voltage input range is 100-240VAC, single phase 50-60Hz. Use only a grounded electrical
outlet when connecting the unit to a power source. If you do not know whether the outlet is
grounded, consult with a qualified electrician.

User Interface Overview
The IPWMM (IP connected wireless modem module) allows the user to monitor the operation of
the repeater and control some of it’s function remotely. The modem connects through a
CDMA200 network and looks and acts like an IP connection. Once the user knows the IP
address of the modem he/she can connect to the repeater using a laptop connected to the
internet.
The IPWMM also can be connected directly to a computer through an Ethernet Crossover Cable
and will then allow local monitoring and control of the repeater. Password protection is used to
control access to the repeater.
The EkoMini will Auto-Setup on Power Up so it is important to ensure the RF input and output
cables are connected before plugging in the unit to a power source. The IPWMM requires up to
3 minutes to load and connect to the network after power up even though the EkoMini typically
sets up in less than 30 seconds.

Remote Connection Through the Wireless Modem
You’ll need to find out the IP address of the modem and enter it into the browser address bar.
The wireless service provider needs to supply this address since the addresses are dynamically
allocated. Be sure there are no firewalls that prevent connection. Wireless service providers
usually operate closed networks, so if the EkoMini modem is on one of those the computer
accessing the EkoMini needs to be on that network too.
Pre-Login Access
You can view some of the settings without logging into the EkoMini. The items are described
