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

Intelligent Distributed Amplifier System (IDAS) is a distributed network of active coverage nodes

controlled by an intelligent head-end called the HE4. The head-end simultaneously supports 2G, 3G, &

4G communication services from multiple carriers. The product is connected to donor antennas that

are normally roof mounted to capture the strongest mobile broadband signals available. The signals are

transmitted from the donor antennas into the head-end where the signals are filtered, balanced to

correct near and far tower signals, amplified, and transmitted to each of the coverage nodes within the

building. Each coverage node is a linear and ultra-low noise amplifier that supports voice, texting, and

demanding data centric applications providing a very scalable in-building network. The major features

include supporting all major networks simultaneously, high speed data, programmable signaling, and

alarm triggers for all degraded network conditions.

The HE4 is a fully programmable device that can adjust uplink and downlink signaling as well as

providing feedback on donor antenna positioning. During idle mode or in a state where no uplink signal

is present, the uplink gain on the HE4 is lower than the maximum gain to reduce electronic noise output.

When an uplink signal is present, the output power is adjusted accordingly as needed for power level

control required for a variety of communication protocols. The product works in conjunction with a

network of coverage nodes and associated donor antennas.

Automatic Shutdown

The detected power levels are monitored by a microcontroller in the HE4. The microcontroller limits the

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

control. The HE4 will also detect low-level self-oscillation and corrects it in real-time. During installation

the HE4 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.

Remote Access

The HE4 has a microcontroller that interfaces to a cellular modem (FCC ID: RI7DE910-DUAL) that

supports remote data access. The modem is continuously checking for an incoming connection, and if

found it will complete the connection and open up a data path to the unit. This allows for a remote

program to monitor the HE4 activity, make any necessary adjustments, or shut down the HE4 if needed.

The internal contained cellular modem (FCC ID: RI7DE910-DUAL) is a dual band device supporting

800/1900MHZ frequency bands as well as CDMA 1xRTT and CDMA 1xEV-DO Rev. A Air Interfaces.

Authorized Equipment

The HE4 has been tested using the antennas and cable.
