SHYAM is a specialist technology company that supports the nation's protectors with solutions conceptualised, designed and developed in India. Built on more than five decades of experience in wireless communications, we develop capability in RF-Cyber system security, mobile phone intelligence and secure communications for homeland security.
It means the intellectual property is held in India and the technology is ours end to end. There is no foreign principal who controls the software, the spares or the support. For a system whose purpose is to protect a secure facility, that independence is not a marketing point, it is part of the security itself.
More than fifty years. Since 1974 we have built capabilities the nation did not yet have, cable television, satellite reception, rural telephony, wireless equipment, mobile networks and, today, sovereign RF-Cyber and homeland-security technology.
Government institutions, defence and paramilitary forces, police and homeland-security agencies, correctional administrations and critical-infrastructure operators, in India and, in line with applicable export controls, internationally.
That the capability a nation relies on for its security is owned and controlled within that nation, designed, built, maintained and upgraded without dependence on any outside party. That is how we build.
Modern covert threats hide inside ordinary wireless traffic. A phone, a bug or a tracker speaks the same signals your building already runs on. Our systems detect, identify and locate these devices, telling an operator what it is, where it is, and why it matters.
A general-purpose analyser shows an operator energy and expects them to interpret it, which needs an expert and still ends in a judgement call. Our systems are built for one job, so they show identity, not just energy: a classified, located answer that a person trained in a day can act on.
Both are possible, but they are different things and we keep them separate. Detection is receive-only, it listens and identifies. Denial or jamming is a separate, controlled capability, supplied only where lawfully authorised. Many of our systems detect, identify and locate without transmitting anything.
Our communication and ISR solutions use proprietary AI and ML analytics to classify signals, reduce false alarms and surface what matters faster. It is applied with discipline, to the problems where it genuinely helps, not as a label.
No. That is a core design goal. Our systems are powerful in expert hands but straightforward under pressure, an operator trained for a day can be effective. We also provide full training.
Across cellular from 2G to 5G, plus Wi-Fi and a range of IoT protocols, depending on the system. Coverage differs by product, we will map the exact coverage to your requirement.
Each is built for one environment. Tell us where you need protection and we will point you to the right one. The quick answers below, and a live demo, make it clear.
EPMPDS, Entrance Point Mobile Phone Detection System, detects and identifies active mobile devices at the entry point of a strategic building or secure office.
SMG, Secure Meeting Guard, creates an RF-sanitised meeting room, denying cellular inside while detecting every device present.
SBCG, Strategic Building Communication Guard, brings a single building under one zoned RF policy. CBCG, Campus & Building Communication Guard, extends that control across a multi-building campus and the ground between buildings.
PCG, Prison Communication Guard, denies, detects and locates contraband phones across the facility, with an optional secure network for staff.
VCG, Vehicle Communication Guard, secures the cabin in transit and detects trackers and bugs while the vehicle is moving.
Our TSCM portfolio, purpose-built countermeasure equipment that detects, classifies and locates covert transmitters others miss.
Border & Perimeter Intrusion Detection, layered BIDS and PIDS systems that detect movement, tunnelling and fence-line intrusion across long, unattended boundaries.
A Mobile Locator and Instant Broadband Communication system for disaster-area operations, instant 4G broadband for responders, presence detection of trapped persons, and last-mile positioning. It sits within our Secure Communication vertical.
Detection systems that are receive-only, listening for and identifying devices without transmitting, are treated very differently from systems that block signals. Legal requirements depend on the system, the deployment and the jurisdiction, so we work within your applicable authorisations and advise accordingly.
Blanket jamming is blunt, it blocks everyone, spills into the surrounding area, and tells you nothing about what was being used or by whom. Our detection systems identify and locate specific devices with minimal spillover, giving you intelligence rather than just a blackout. Where denial is genuinely required, it is a separate, authorised capability.
Our detection and denial systems are intended for authorised government-approved organisations. Certain capabilities, including jammers, are supplied only to authorised users and, in the case of jammers, for export only. We confirm eligibility before any supply.
In line with applicable export controls. Jammers, specifically, are offered for export only and supplied strictly to authorised users within applicable spectrum and legal authorisations.
Detection systems are designed to operate without interfering with licensed networks, and without dependence on mobile operators. Any denial capability is engineered to contain its effect to the authorised area.
It depends on the system and site, but our detection systems are designed for rapid set-up, some are operational within minutes of installation. We survey your site and confirm timelines up front.
End to end. We conceptualise, design, develop, plan, install, operate, maintain and provide lifetime upgrades in the field. You deal with one accountable party from survey to disposal, there is no systems integrator standing between you and the manufacturer.
We provide structured training, from operating specific systems to broader counter-intelligence and RF-Cyber awareness, delivered by the team that designs and builds the equipment.
Whole-of-life support: calibration, maintenance, spares and upgrades for the full service life of the system, all from within India, with no dependency on a foreign principal for support.
Yes. Because we own the full technology stack, we tailor products, integrated systems and complete systems-of-systems to your exact mission, rather than forcing your mission to fit a fixed product.
Depending on the product, configurations span portable, tactical and fixed deployments. We match the configuration to your operational environment.
Yes, and we recommend it. A specification describes a system; a demonstration proves it. We will show the system detecting, identifying and locating devices in real time, in the configuration that matches your environment.
Use the "Book a Demo" form on the site, or contact us directly. For sensitive product information, kindly write from an official organisational email.
Our systems are intended for authorised government, defence, law-enforcement, correctional and critical-infrastructure organisations. We verify eligibility as part of the process.
Yes, a brochure and a detailed brochure are available. For detailed or sensitive material, we ask that requests come from an official organisational email.
