This equipment will generate radio signals and could continuously emit RF energy. Avoid prolonged

exposure to the antennas and maintain a 12 inch clearance from the antenna while the system is

operating.

Power for this equipment shall be supplied through wiring installed in a normal building. If powered

directly from the mains distribution system, it shall be used additional protection, such as overvoltage

protection device.

Only manufacturers recommended antennas, cables, and passive devices shall be used with this

equipment.

Opening the chassis will void the warranty.

Always power off the unit prior to performing any work.

To meet FCC Part 27.50 compliance, the installation height of the donor antenna for an AWS band

(1700/2100 MHz) operation is limited to 10 meters above ground.

WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and

this device. Unauthorized use may result in significant forfeiture penalties, including penalties of $100,000

for each continuing violation.

FCC Information

FCC ID: 2AEQJ-CP4-001

WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and

QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC Licensee to

operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in

excess of $100,000 for each continuing violation.

Warning: Changes or modifications to this device not expressly approved by the manufacturer could

void the user’s authority to operate the equipment.

You MUST operate this device with approved antennas and cables as specified by the manufacturer.

Antennas MUST be installed at least 30 cm (12 inches) from any person.

Industry Canada Regulations

IC ID:

This Class B digital apparatus meets all requirements of the Canadian Interference Causing Equipment

Regulations. 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.

The term “IC” before the radio certification number only signifies that Industry Canada technical

specifications were met.

RF Exposure: The 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 dB,

especially where the output is re-radiated and can cause interference to adjacent band users. This

power reduction is to be by means of input power or gain reduction and not by an attenuator at the

output of the device.

Cet appareillage numérique de la classe [B] répond à toutes les exigences de l’interférence canadienne

causant des règlements d’équipement. L’opération est sujette aux deux conditions suivantes: (1) ce

diapositives peut ne pas causer l’interférence nocive, et (2) ce dispositif doit accepter n’importe quelle

interférence reçue y compris l’interférence qui peut causer l’opération peu désirée.

Le fabricant nominale de la puissance de sortie de ce matériel est simple transporteur. Pour les

situations lorsque plusieurs signaux porteurs sont présents, l’évaluation devrait être réduite de 3.5 dB,

en particulier lorsque le signal de sortie est réémise et peut provoquer des interférences adjacentes à la

bande utilisateurs. Ce pouvoir est de la réduction par le biais de la sortie d’alimentation ou la réduction

de gain et non par un atténuateur à la sortie du dispositif.

Please note: This unit has been approved for use in Canada under RSS 131, however, consent for the use

of this device to improve mobile communications coverage, must be obtained through your mobile

network provider, prior to placing the unit in operation. Please refer to the Industry Canada document

Distributed Antenna System Overview

Cellular signals from outdoor cell towers may not provide clear and consistent coverage inside buildings,

consequently wireless operators and building owners use distributed antenna systems (DAS) to

broadcast cell signals throughout their facilities.

In-building weak signals are produced by a variety of reasons, including LEED construction, base station

position, building position, construction material, in-building content, etc. Within a building the cell

signals can be strong near the external walls and become non-existent as the signals try to propagate

within the building. Typical in-building signal loss can be seen in Table 1.

Table 1: Typical Signal Loss in Buildings

Signal loss is a key term used in the cellular industry. For each 3dB of loss in signal strength, this

represents the ability to make a call or not. The range of operable cell signals can extend from very

strong -50dB signals—when a subscriber is standing next to a cell tower—to very weak signals of -95dB

or weaker. At -95dB, a call may get through at times, but the subscriber will be frustrated by the

number of dropped calls and overall poor call quality. Also data applications are much more vulnerable

to weak signals, causing constant retransmissions and resulting in reduced data rates.

In-building DAS can eliminate problems associated with signal proliferation, coverage, and capacity for

voice and data applications. In-building systems work by distributing cell signals throughout an interior

space: the signal is typically brought to the building using roof-mounted donor antennas or with a base

station (BTS) installed in the telecommunications equipment room. The donor antennas or BTS is then

connected to the DAS using cabling. The DAS network of antennas is placed strategically throughout the

building to provide voice and data services.

Product Description

The CP4 Coverage Node (CP4) is designed to provide 2G, 3G & 4G communications within a building

covering 5,000 square feet of coverage at each location supporting an Omni or directional antenna. The

product provides reliable cellular communications within all types of in-building environments. The

major features include high speed data services, low power operation, alarm triggers, remote access and

status reporting.

The CP4 is part of the Intelligent Distributed Amplifier System (IDAS) family of products and supports

Cellular, PCS, LTE and AWS commercial cellular communications as well as public safety radio

communications. The IDAS works with multiple coverage nodes strategically placed within the building

to provide reliable texting, data, and voice communications. All coverage nodes in the system are

networked together to deliver a balanced and reliable signal throughout the facility. The head end unit

manages all of the amplifiers in a system along with local and remote access for monitoring and status

checking.

Automatic Shutdown

The detected power levels are monitored by a microcontroller in the CP4. The microcontroller limits the

maximum output power to keep the amplifiers linear without interfering with the network power

control. The CP4 will also detect low-level self-oscillation and corrects it in real-time. During installation

the CP4 alerts the user with LED outputs to adjust the position of the antennas if the unit is self-

oscillating to clear the issue. If the microcontroller cannot correct the self-oscillation it will shut the unit

down to protect the network and notify the user with LED outputs on the unit.

To resolve oscillation, increase the antenna separation between in-building antennas or provide

improved isolation from the outside donor antennas and the in-building antennas. This isolation should

be in the order of 70 dB and is usually obtained by mounting the outside antenna away from the edges

of the roof. The use of window mounts or other non-rooftop mountings should be avoided.

Authorized Equipment

The CP4 has been tested using the antennas and cable.
