FCC Regulatory Information

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.

Any changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.

Part 15 TV Band Device Notice

This equipment has been tested and found to comply with the rules for TV bands devices, pursuant to
part 15 of the FCC rules. These rules are designed to provide reasonable protection against harmful
interference. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio
communications. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

(1) Reorient or relocate the receiving antenna.

(2) Increase the separation between the equipment and receiver.

(3) Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.

(4) Consult the manufacturer, dealer or an experienced radio/TV technician for help.

Caution: Exposure to Radio Frequency Radiation.

To comply with FCC RF exposure compliance requirements, for fixed configurations, a separation
distance of at least 40 cm must be maintained between the antenna of this device and all persons.

This device must not be co-located or operating in conjunction with any other antenna or transmitter.

Hardware Installation

ACRS 1.0 is the first generation Adaptrum cognitive radio system covering spectrum bands from
400 MHz to 1 GHz. ACRS 1.0 is specifically designed to operate in the UHF TV Band (470 MHz – 698
MHz), as TV Band Devices compliant to the rules specified in CFR 47 Part 15 Subpart H. To be rules
compliant, ACRS 1.0 systems must operate as Fixed TV Band Devices and must be professionally
installed.

ACRS 1.0 radio unit is enclosed in a 2U size box whose front panel and back panel are shown in

the following pictures. Both the base station and the client station use the same radio unit.

ACRS 1.0 system has been authorized for use with the supplied Kathrein CL-1469B UHF-TV log-

period antenna or Antenna Direct DB2E antenna or PCB Bowtie antenna. Only the following antenna
types can be used with the ACRS 1.0 system:

1) Log-periodic antennas with a gain of 10.15 dBi or less.

2) Bowtie antenna with backplane reflector with a gain of 11.8 dBi or less.

3) Print-circuit-board (PCB) omni-directional bowtie antenna with a gain of 2.3 dBi or less.

The antenna used with the ACRS 1.0 system must have well characterized gain. Antenna feed cable loss
should also be characterized.

The installer must ensure that the antenna assembly meets the following requirement:

Antenna EIRP – Feed Cable Loss – Attenuator Setting = 7 dBi

Here the “Attenuator Setting” is a software programmable output attenuation setting for the radio
device that can be programmed at installation time (referring to Section “Post-Installation Setup” for
discussion on how to program the setting). As an example, when a 10 dBi EIRP antenna and a feed cable
with 1 dB loss are used, the “Attenuator Setting” must be programmed to:

Attenuator Setting = 10 dBi – 1 dB – 7 dBi = 2 dB

The “Attenuator Setting” programming must be done correctly during installation to ensure the
device is compliant with the CFR 47 Part 15 Subpart H rules.

Client station installation diagram.

The above figures show the hardware installations at both the base station side and the client
station side to allow the client side networking devices to connect to the Internet through the TV
whitespace link between the base station and the client station.

For both the base station and the client station installations, the ACRS 1.0 radio N-type
connector is connected to the feed cable which is connected to the antenna. The Ethernet ports of the
base and client radios are connected to Ethernet ports on the base control PC and client control PC.

Both the base control PC and the client control PC have dual Ethernet ports. One of the Ethernet
port is connected to the radio. The second Ethernet port on the base control PC is connected to a router
or switch that connects to the Internet. The second Ethernet port on the client control PC is connected
to a broadband router or switch which connects to the client side networking devices.

Once the hardware installation is complete, follow the instructions in the following sections to
perform the software installation on the control PC. Note if an installed radio unit and control PC are

redeployed at a differently location, the installer must uninstall the old software and reinstall the
software on the control PC.
