UTILIZING SANCHAR PRODUCTS IN MANAGEMENT INDUSTRY

LICENSE RADIO

Problem Statement

Jungle areas often lack mobile phone network coverage, leaving forest authorities reliant on wireless voice communication.

Solution

Sanchar has provided a solution by supplying the VHF band communication via a 25-watt base station, employing analog station model SCM-910HV to the Forest Department. This technology enhances their communication capabilities, ensuring efficient and reliable voice communication within these remote jungle areas, even when mobile networks are unavailable. Licensed radios are crucial for forest management, enabling effective communication among rangers, officials, and teams, ensuring swift response to emergencies, and supporting coordinated wildlife conservation efforts.

In vast jungle areas spanning many miles, traditional VHF sets for communication operate on a point-to-point basis within a limited line-of-sight range. This leaves numerous range offices outside the reach of the forest headquarters station, forcing operators to manually relay messages to remote stations.

Solution

DIGITAL RELAY RADIO

Problem Statement

Sanchar has introduced a cutting-edge solution called "Digital Relay Radio," also known as "Single Frequency Repeater" (SFR), to address this issue. The subscriber radio model G5Ui in the DRR network has a low throughput, equivalent to an RF power output of 4/5 watts. However, the DRR extender, like a VHF base station, can extend the RF signal up to 30/35 kilometres with a power output of 10 watts. ØDigital relay radios extend forest communication networks, ensuring connectivity in remote areas. They enhance forest operations, enable efficient coordination, and facilitate timely response to threats like poaching and fires

PRACTICAL APPLICATIONS

PRINCIPAL OF RELAY RADIO IN A NETWRK

The above four walkie-talkie are situated in such a position, i.e. A to B, B to C, C to D are same distance of 2km (maximum talking range of a conventional radio at normal LoS condition). Here in Relay Radio System, Radio at A can talk with Radio D and further, where radio at B & C relay the voice signal to and further, without a substantial delay.

In Practical field, for more long range communication requirement we may replace radio B & C, by our high power DRR, model G10Ui-DRR

PRACTICAL APPLICATIONS

MOST SIMPLE APPLICATION OF DRR EXTENDER SOLUTION SYSTEM

Message transfer through single freq. Digital Relay Radio System

VEHICULAR APPLICATION SIMILAR TO CONVENTIONAL RADIO SYSTEM

PRACTICAL APPLICATIONS: JUNGLE

Extension of Radio Range by Digital Relay Radio Extender, Providing a Long Range Walkie-Talkie Network

USE OF MULTIPLE DRR EXTENDER IN CASE OF LONG RANGE WALKIE TALKIE COMMUNICATION ONLY BY A SINGLE SPOT FREQUENCY

LONG RANGE WIRELESS COMMUNICATION ON MOVE IN JUNGLE AREA, WITHOUT HAVING ELECTRICITY

THIS IS UNDER LICENSE FREE SCHEME

DRR APPLICATIONS

COMPLETE VIEW OF CONNECTIVITY BETWEEN PROPOSED DRR LOCATION FOR ANDAMAN & NICOBAR FOREST DEPARTMENT AS OBTAINED BY A SOFTWARE SURVEY

It Implies that one Walkie-Talkie model G5Ui at “AERIEL BAY” or “DIGLIPUR” will be in a position to talk directly with another same Walkie Talkie at “HUT BAY” in little Andaman Island without any significant delay, over an Aerial Distance of 300km

THIS IS THE BEAUTY OF THIS DIGITAL RELAY RADIO NETWORK

BODY WORN CAMERA

Problem Statement

The Forest Department faces multiple challenges, including groups of elephants entering surrounding villages, forest fires in the summer season, and poachers endangering wildlife and stealing forest resources.

Solution

To address these challenges, equipping all forest guards with Body-Worn Cameras (BWCs) can provide crucial evidence against poachers and help identify criminals. Additionally, implementing the Sanchar Dash Camera System enhances the management and control of forest fires, ensuring efficient response and reduced damage to precious forest ecosystems. Forest personnel use body-worn cameras for evidence collection and safety. These devices document encounters with poachers, wildlife, and illicit activities, enhancing accountability and aiding law enforcement efforts. Dash cameras in forest vehicles enhance safety and document incidents. They provide crucial evidence in case of accidents, support resource management, and improve surveillance for forest protection.

BODY WORN CAMERA

All Forest Guards Should Be Provided With BWCs To Gather Evidence Of Poaching And Thereby Identify The Criminals.
