FCC Part 15.19

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.

FCC Part 15.21

Any changes or modifications (including the antennas) made to this device that are not expressly approved by the manufacturer may void the user's authority to operate the equipment.

RF Exposure Statement

FCC RF Radiation Exposure Statement: This equipment complies with FCC RF Radiation exposure limits set forth for an uncontrolled environment. This device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter.

Safety Precautions

Opening the OTA equipment could result in electric shock and may cause severe injury.

Connect the equipment frame ground to the building ground.

Operating the OTA with antennas in very close proximity facing each other could lead to severe damage to the repeater.

RF EXPOSURE INFORMATION A minimum separation distance of 7.9 inches (20cm) must be maintained between the user and the external antenna of the repeater to satisfy FCC RF exposure requirements. For more information about RF exposure, please visit the FCC website at www.fcc.gov

This equipment is for indoor use only and enables the communication wiring to communicate inside the building only.

ALC (Automatic Level Control)

ALC feature prevents the repeater from exceeding its maximum output power by reducing the gain automatically. ALC is used to adjust the gain to an appropriate level for a range of input signal levels.

ASD (Automatic Shutdown)

Automatic shut down protects the repeater from the oscillation or excessive input signal and eliminates any degradation to the network.

There are three parameters: ASD Level, ASD Time, and ASD Iteration. If the output power reaches higher than the “ASD LEVEL”, the repeater will shut down for “ASD

TIME” seconds and then it will turn the amp back on to measure the output power again. If this

repeats at “Iteration” times, the repeater will shut down permanently.

1. Introduction

QUAD BAND OTA is used to fill out areas in QUAD BAND systems, such as base station fringe areas, business and industrial building, etc. QUAD BAND OTA receives signals from a base station, amplifies and retransmits the signals

to the mobile stations. It also receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously with the following features:

QUAD BAND OTA Key Features

◈ Composition(4 BDA by service band and combining Unit)

- 700MHz Band BDA for LTE Service

- Cellular Band BDA for EVDO/CDMA2000 Service (LTE Service is possible even the Firmware update only)

- PCS Band BDA for EVDO/CDMA2000 Service

- AWS Band BDA for EVDO/CDMA2000 Service (LTE Service is possible even the Firmware update only)

- Combining Unit (MUX) is for input and output signal of each BDA to a single antenna.

◈ Design(Each BDA is possible to service selected channels by the user within a band.)

- Possible to select any channel combination within a band caused by the Digital Filter.

- Using the Digital Filter: High quality, out of band rejection, high performance

◈ Possible to combine the BDA according to Band.

- Each BDA can be used as a stand alone unit(Use Privacy Ant Port)

- Possible to combine the BDA(Dual, Tri, Quad-band)

◈ User friendly design.

- Local monitoring and control through the Web GUI interface

- Remote monitoring and control through the Remote Access and Control

- Reports the status of connection as a function of SNMP regularly and reports an alarm if the event occurred. ◈ Protection function

- Isolation and Oscillation Check

- Isolation cancellation Function

- Auto Gain Control

- Auto Shutdown

◈ Service Coverage

- Possible to service by 25k square feet

- Use in office buildings, warehouses, underground parking lots, etc.
