1) FCC Regulatory Information

This device complies with Part 15 of 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 §15.706 TV Band Device Notice

This equipment has been tested and found to comply with the rules for white space 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 40cm 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.

Part §15.105 Information to the user

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. 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. However, there is no guarantee that interference will not occur in a particular installation. 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:

—Reorient or relocate the receiving antenna.

SL-TVWS-1001-User Manual and Installation Guide

—Increase the separation between the equipment and receiver.

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

—Consult the dealer or an experienced radio/TV technician for help.

3) Glossary

Base Station or Base Unit is the WSD which is configured to bridge the packet flow to a router or point of presence (PoP). Several CPEs or Client Units connect to the Base Unit

Bit Error Rate is the %age of bits which are in error on the radio link. The target BER can be configured based on the current deployment conditions

Customer Premise Equipment or Client Unit is the WSD at the user end and registers with the Base Unit.

Effective isotropic radiated power is the radio power in dBm measured at the output of antenna. It is equal to the total conducted power + the antenna gains in dBi

TV White spaces are the unoccupied bands between TV channels which are used for broadband service

Wireless Regional Area Network is a wireless broadband specification defined by IEEE802.11a

specifications

White Space Device is a wireless communication device that works in TVWS

White Space Database is the database of usage of TVWS in a given region

4) TVWS Meghdoot (Base Station) and Dhaval (Customer Premise

Equipment) radio

Saankhya TVWS devices are fixed cognitive radio devices operating in TVWS bands ranging from 470-608 MHz. The devices can be configured as either Base radio or Client radio and are compliant with rules specified in CFR 47 Part 15 subpart H of FCC regulations. When acting as a Base radio, device acts as a master and Client radios act as slave. All the communication with external network (including with WSDB) is handled through the Base radio

SL-TVWS-1001-User Manual and Installation Guide

6) BS Installation

Meghdoot BS should be installed by an authorized professional only. Installation and operation of the devices by persons other than the professional installers might cause permanent damage to the device and malfunction.

Saankhya TVWS devices have 3 ports – 2 for antenna and 1 for PoE as shown in Figure 4. These devices are mounted on a pole with the help of clamps and screws provided with standard shipment. The antenna are connected to the N-type connectors for the purpose on the top section of the devices. The RJ45 PoE port on the device is connected to PoE injector (Figure 3) using Ethernet cable.

Figure 3 PoE Injector and connections

The Ethernet cable on the PoE injector which forks from the power connector should be connected to backhaul – either a switch or a router depending on the operator topology.

SL-TVWS-1001-User Manual and Installation Guide

Figure 4 Saankhya TVWS Device

Notes:

1) The devices should be mounted vertically with the PoE port facing earth in order to reduce wind

resistance

2) Clamps should be secured firmly in order to avoid any injury or damage resulting from the box slipping

down the pole

7) BS Configuration

Make sure that all the connections are done as described in Section 6) Launch the TVWS GUI Application by double clicking on the application icon. Follow the steps as described below to configure the base station

7.1 Configure a WSDB provider

Note:

3) This step is optional and required only if TVWS databases need to be accessed. Otherwise go directly

to Section 7.3 (at locations where WSDB services are not mandated by law)
