EMS Wireless EkoMini Manual

1.0 Introduction

This small, powerful RF repeater will provide indoor coverage for approximately 5,000

to 75,000 square feet (500 to 7,000 sq. meters) of office building floor space. This

makes it ideal for small to medium size office buildings, retail stores, restaurants, etc.

The EkoMini

supports all system protocols including CDMA, GSM, TDMA, AMPS,

etc., and is available in models that cover all licensed 1.9 GHz PCS bands A through

F, Cellular A, B, (and their extensions), ESMR 806-869 MHz and Cellular Full Band

(824 to 894 MHz).

Band selective filtering in both uplink and downlink signal paths is accomplished with

surface acoustic wave (SAW) filtering at an intermediate frequency (IF) to provide

maximum selectivity from out of band carriers. The same voltage controlled oscillator

(VCO) is used for up conversion as well as down conversion to eliminate frequency

shift.

The EkoMini

features software controlled automatic set-up, a lightweight compact

enclosure, optional remote alarming, excellent electrical specifications, and high

reliability.

The EkoMini

is a versatile “building block” that can be used in a variety of system

designs. The block diagram in Figure 1 shows a simple indoor system design.

Multiple units (cascaded or in parallel, including multi-band combinations) can be used

in larger buildings to expand coverage by placing different EkoMini repeaters at

strategic locations.

The system design in Figure 2 shows a much more sophisticated dual-band (Cellular

800 MHz/PCS 1900 MHz) cascaded system for coverage up to about 150,000 square

feet (14,000 sq. meters) for each band. This system could be used by a carrier with

licensed spectrum in both the 800 and 1900 MHz bands, and desires simultaneous

coverage with one indoor system. Separate donor antennas and repeaters are used

for each band. A directional coupler taps off a small portion of the signal from the first

pair of repeaters, and feeds the signal to the second pair of repeaters. Each pair of

repeaters provides coverage to separate areas of a large building. This system is

versatile, configurable, and quite inexpensive. Other similar systems may be designed

to accommodate other building layouts.

The EkoMini

has 70 dB gain and +20 dBm composite RF output power. One to

approximately four server antennas may be connected in parallel with a coaxial power

EMS Wireless

EMS Wireless EkoMini Manual

divider to distribute signal throughout a building. The server antennas are frequently

very small, particularly at PCS. Many of them mount directly to acoustic ceiling panels,

or are embedded directly into the panel so they are totally invisible to the building

occupants.

The EkoMini

optional remote alarming feature allows a simple means of remotely

alarms from the unit, as well as monitoring basic performance parameters of the

repeater. This is done using any standard computer with a terminal program, and a

modem. The alarms generally indicate performance situations that require correction,

such as no downlink signal present at the repeater output (if, perhaps, the donor BTS

goes off the air).

Up to three digital pager numbers and paging PIN numbers can be programmed for

use in case an alarm is issued. The unit will send an alarm to the first number when an

alarm occurs. 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.

A small external power supply is supplied, which plugs into any 100 – 240 VAC, 47 –

63 Hz outlet. Both the repeater and the power supply are totally convection cooled,

with no cooling fans. No user maintenance is required.

3.4 Installing the EkoMini

Note: Only qualified technicians should perform the installation. 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: This device complies with Part 15 of the FCC Rules. Operation is subject to the

condition that this device does not cause harmful interference.

The EkoMini

is designed for indoor use only. It should not be mounted outside.

• Determine the donor and server antenna(s) locations. Choose a location for the

EkoMini

that will minimize coaxial cable lengths to these antennas, while

maintaining adequate isolation. Also, choose a protected area such as an

electrical or telephone room so the EkoMini

will not be physically damaged.

The location must also be near a 100 - 240 VAC, 47 – 63 Hz outlet. See Figures

7 and 8 below – do not apply AC power without the coaxial cables and

antennas installed!
