EkoMini™ Manual
Description
The EkoMini is a band selective, 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, homes, etc.
The EkoMini is housed in an indoor mountable enclosure, and is powered with a
regulated wall mountable power supply.
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.
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 setting. 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.
EMS Wireless EkoMini Manual
EMS Wireless
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 controlled 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. See Figure 1 below.

If a unit is initially set-up or moved from one location to another, pressing and holding
the reset switch a minimum of 5 seconds until the LED’s blink will restart the automatic
set up feature. If the peak limit and uplink gain offset switches are preset when the unit
is installed the EkoMini will first attempt to set itself up to the full RF output power of 20
dBm and then reduce power as instructed by the peak limit and uplink gain offset
switches.
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 output power on both paths to
prevent overdrive. Should the downlink detected 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.
The output power level setting and the maximum detected level, along with date and
time, are recorded in the history log file.

EkoMini Cellular Band switches 3 and 4 are used to EkoMinimize the gain of the
adjacent bands control channels by increasing the frequency roll off in band. It should
be noted that the two switches shift the center frequency of the band; they do not
change the bandwidth of the filter. The operation band is preset by the factory and not
customer changeable.

The units are factory set for filter centering at the middle of the bands, therefore
channels at the beginning and end of the bands will be filtered out. For example, in the
“B” band, channels 334 to 337 will be filtered out. Likewise in the “A” band, channels
330 to 333 will be filtered out.
If a customer needs to utilize channels near the band edges that might otherwise be
filtered out, EMS can custom fit the filtering to meet the customer’s needs.
EkoMini ESMR Band switches 3, 4 and 5 are unused; channel bandwidth is preset by
the factory per customer request.
Remote Alarming
Remote alarming is accomplished with a factory installed modem and software option.
The EkoMini microprocessor will detect the modem and initialize the required software.
By dialing into the unit, it may now be programmed to the desired response numbers
and alarm codes. Access to programming mode requires entering a user selected 5digit password.
EMS Wireless EkoMini Manual
11
EMS Wireless
A factory default password is preprogrammed into the unit as 11111. The user may
change this in the program mode of operation. There is also a factory access
password.
Up to three numbers and alarm codes or paging pin numbers can be sent. The unit
will send an alarm to the first number when an alarm occurs. (The alarm is not sent
during the red flashing alert period. It is delayed 5 minutes to be certain the alarm will
not clear itself). Each additional number and alarm, which has a programmed
sequence, will be sent after the programmed delay. The delay, which is set, is a time
measurement from initially sending the first telephone call and alarm. The three

Telephone number 2 delay is the time between dialing out number 2 after number 1
has been dialed. Accordingly telephone number 3 delay is the time between dialing
out number 3 after number 2 has been dialed.
Should an alarm condition clear, the EkoMini will send an Alarm Clear alert to the
same number or numbers that were alerted previously. As an example the alarm
condition could occur if the base station was turned off for maintenance.
The unit will record time, date and cause of the last 25 reportable (alarms present after
5 minute alert delay) alarms. The user may download these via the modem connection

or factory personnel may also review them. Retrieving log history requires entering the
password.
Command, Clear Log File, is accessible only with the factory password.
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.

*Optional, Telephone cable 6 ft.
*Only needed with external alarm.
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.
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 AC source and connect 9 VDC output to EkoMini
DC Input.
-Optional connect telephone line to RJ11 jack.
Refer to attached drawing for any clarification. (Page 16)
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.
EMS Wireless EkoMini Manual

EMS Wireless
Select mounting location of Rerad antenna to provide maximum coverage while
maintaining at least a 20-foot spacing from closest cell phone usage if possible to
reduce the possibility of overdrive.
IMPORTANT: Before performing channel or amplitude adjustments on any unit, make
sure power is OFF.
System Set Up Instructions:
-During initial set-up, downlink signal must be presented to the unit.
-Apply Power after setting user switches and unit will automatically set up.
-Set Band Switches to desired Band for PCS or 3 dB roll off point for Cellular SW 3 &

and after 5 more minutes (or 15 minutes after the original alarm) Report 3 will be
contacted. If Report 2,3 Dial out numbers are not changed the EkoMini will
attempt to contact Report 1 when the delay time has expired. After setting up the
Dial Out number and if necessary the Pin number (used for some paging
systems) The Unit MUST be issued the Activate Report Alarms Command: ( set
rp actv Answer = yes ). If this step is skipped the unit WILL NOT report remote
alarms. The unit then should have the Answer Rings set, if they are not set the
EkoMini will DEFAULT to answer on 2 rings. The next step would be to set the
time and date.

STEP 3. Testing the Reporting.
A. Testing the remote alarming.
test report 1
Note: Before logging off the unit, it is advisable to test the configuration. By
issuing a test report 1 command, the unit will log the user off and try to
send an alarm code to the Report 1. If there are no alarms, it will send a 0.
Keep Alive Functionality
Theory of Operation:
The EkoMini's Keep Alive can be set up to function in one of various
formats. The unit can either be reactivated for an additional 24 hours by (1)
either dialing out and send the site location and alarm string to a computer
or (2) it can expect to receive a call and will report site location and alarm
status. If there is a failure of communication with the remote computer the
unit WILL SHUTDOWN and report alarm condition if possible. The unit will
then need to have it's power cycled or reactivated by the remote computer
if the unit can be contacted (should the deactivation be related to power
failure, telephone line out, etc. at the remote computer location).
Setting up Keep Alive:
STEP 1. Connect to Unit.
STEP 2. SET KACTV YES.
STEP 3. Confirm Activation.
STEP 4. SET KTYPE --- Dial or answer
STEP 5. SET KMESSAGE --- What to send. If ASCII is selected the unit
will attempt to connect and send a status screen.
STEP 6. SET KRING --- Modified ring amount used for line share purposes
STEP 7. SET KDIAL --- the Telephone Number to try to contact.
STEP 8. Set KRTRY --- Number of retries before alarming/shut down
STEP 9. TEST REPORT KADIAL --- Test the Keep Alive Telephone
Number
Important Notes:
IF Keep Alive is set to Active and IF UNIT IS NOT CONTACTED IN 24
Hour time period IT WILL SHUTDOWN.
