1. Safety and Environmental

The electrical installation has to be performed in

accordance with the safety regulations of the local

authorities. Due to safety reasons, the electrical

installation must be performed by qualified

personnel only. The repeater must not be opened.

The antennas of the repeater (integrated and / or

external) have to be installed in a way that the

regional and national RF exposure compliance

requirements are met.

To comply with FCC RF exposure compliance

requirements, the following antenna installation

and device operating configurations must be

satisfied: A separation distance of at least 20 cm

must be maintained between the antenna of this

device and all persons. RF exposure compliance

may need to be addressed at the time of licensing,

as required by the responsible FCC Bureau(s),

including antenna co-location requirements of

1.1307(b)(3). Maximum permissible antenna gain

is 12 dBi.

The miniRepeaters must only be used for

indoor applications!

2. Quick-Start Checklist

 Adjust channel(s); see chapter 10.

 Mount the repeater; see chapter 6.

 Install donor and coverage antennas.

 Provide the repeater with power; see chapter 3.

 Adjust the attenuation; see chapter 12.

Start the adjustment with the maximum attenuation

and decrease attenuation until the ALC becomes

active and the ALC alarm LED lights up. Then

increase attenuation until the ALC alarm is inactive

again.

 Select auto-setup; see chapter 12.

 Check for alarms; see chapter 13.

3. RF and Power Connectors

G0783ZR

The miniRepeaters are equipped with two RF antenna

ports: one antenna port that provides RF signals

to/from mobile(s) and another antenna port on the

opposite side of the miniRepeater that provides RF

signals side to/from the BTS. Both of these

connectors are SMA-Female. Two coaxial jumper

cables are included with the miniRepeaters to provide

N-female connection ports.

The socket for the DC supply is situated to the right of

the “to/from BTS” RF connector. The power supply

voltage for this connection point is 6.7 to 7.5 VDC,

with a typical current draw of 1.7 amps. Only the

Power Supply Unit (PSU) supplied with the

MiniRepeater must be used.

An alternative method to provide power to the

MiniRepeater is through the “to/from BTS” RF

connector via the coaxial cable and a bias-T at the

source. The DC socket of the repeater must not be

connected if the unit is biased via the RF port.

Mounting bracket Wall manual Attenuation setting automatic E0783B0 Downlink signals from the BTS reach the internal duplexer through the “to/from BTS” RF port. Following the DL path from the duplexer, the RF signals are amplified by an LNA, which feeds the amplified signals to a mixer.

10. Start-Frequency Switch Settings As described in chapter 4 Functional Description, the miniRepeaters utilise a high rejection filter to allow only the desired frequency band to be repeated. The miniRepeaters are available in different bandwidths with field adjustable start frequencies to support the desired frequency band of the user. Following are tables that show the filter band-pass start frequencies corresponding to the switch settings.

11. Standard Frequency Band Settings The following tables show SF switch settings that would provide the appropriate passband frequency response required for specific SF bands. Note that the passband response may be different than the filter bandwidth of the miniRepeater. In these instances, the miniRepeater high rejection filter is used in conjunction with the duplexer response to narrow the actual band-pass response.

12. Attenuation Setting The attenuation of the miniRepeater can be set by means of a rotary switch. There is a label on the miniRepeater that shows the possible positions of the rotary switch and the corresponding values of the attenuation. The attenuation can be set, using a small screwdriver, in the range from 0 dB to 20 dB in steps of 2 dB or “auto setup” may be selected. When auto setup is selected, the miniRepeater will automatically set its gain to maximize RF performance.
