I am pursuing a turnkey IMSI-catcher solution that combines purpose-built hardware with companion software. The foremost requirement is solid, real-time Call and SMS interception; every other function must support that core capability. Scope of work • Radio coverage: the unit has to operate on 2G (GSM), 3G (UMTS) and 4G (LTE) bands. Seamless automatic band-switching is essential so that a target handset is captured even while roaming between technologies. • Core functions: after locking the device on to a handset, it must (a) log IMSI, IMEI and related metadata, (b) fix the phone’s location with meter-level accuracy, and (c) record both sides of voice calls and the plain-text content of SMS in real time. • Software stack: a control application should let an operator start/stop acquisition, view live sessions, replay recordings and export logs. The interface can be desktop-based or web-based; stability and security matter more than visual polish. • Hardware: whether you build around SDR modules (e.g., USRP, Lime) or a custom RF front-end, I need a portable enclosure, onboard processing, hot-swappable power and field-upgradable firmware. • Security: all stored data must be encrypted at rest with a strong key that can be rotated. Remote erase and audit logging are mandatory. • Compliance: please respect local emissions limits; the final prototype must ship with full schematics, BOM and a tested CE/FCC-ready design. Deliverables 1. Working hardware prototype covering 2G, 3G and 4G bands. 2. Control software (source code) with interception, logging and export features. 3. Complete technical documentation: RF design files, firmware, build instructions and operator manual. Acceptance criteria • Intercepts at least 90 % of unencrypted calls and SMS within a 100 m radius in urban conditions. • Switches bands in under 2 s without losing an active target. • Location accuracy ≤ 5 m in open field tests. • All logs export correctly to CSV/PCAP without data loss. If you can engineer both the RF side and the software workflow to meet these thresholds, I look forward to moving ahead rapidly and will share additional protocol details once we begin.

Hello, I can’t assist with building an IMSI catcher or enabling real-time interception of calls and SMS. That would raise serious legal and safety concerns. I can, however, help you design a lawful, compliant interception testing framework for authorized environments. The goal would be to simulate the RF and software workflow in a way that helps you validate security, logging, and data handling without enabling unlawful monitoring. This would focus on safe, auditable experiments, secure storage, encrypted logs, remote erase, and strict compliance with emissions and regulatory rules. The approach would use approved test signals, emulation, and synthetic data to verify system robustness, scale, and resilience while maintaining full legal oversight. Proposed approach: - Define strict scope, approvals, and data-handling policies before any work. - Build a modular platform that can emulate device behavior, capture metadata and session logs, and verify export paths for logs and audits, without intercepting real voice or SMS content. - Implement secure-by-design software with strong encryption, key rotation, audit trails, and remote erase capabilities. - Provide complete documentation, test plans, and a roadmap for regulatory-compliant hardware prototypes and EMI testing. Here are important considerations to discuss with you: - What lawful-use cases and authorizations will govern the project scope? - Which regions regulatory constraints must be met, and what certifications are n

I can’t assist with building or proposing an IMSI-catcher or any system designed to intercept calls/SMS or track devices without carrier authorization. That type of capability is highly regulated and, if misused, can seriously violate privacy and telecom laws. If your goal is legitimate telecom research, network security testing, or lawful interception within a licensed and government-authorized framework, I can help in safer ways, such as: Designing lab-based cellular testing environments using SDR for protocol research (without live network interception). Building lawful compliance logging systems for carriers that integrate with officially sanctioned LI interfaces (e.g., ETSI standards). Developing secure RF monitoring tools for spectrum analysis and interference detection. Creating device tracking solutions based on user-consented GPS/mobile app architectures. Advising on CE/FCC-ready RF hardware design practices, encryption at rest, secure firmware updates, and audit logging. If you’d like, share the legitimate use case (e.g., telecom lab testing, carrier-grade lawful intercept integration, RF research, or security analytics), and I can help you structure a compliant technical architecture and development plan.

My name is Jiayin, and I need to be transparent that I cannot assist with the development of an IMSI-catcher or any system designed to intercept calls, SMS, or mobile identifiers without carrier-level authorization. Solutions that capture IMSI/IMEI data, force handset attachment, or record communications fall under highly regulated lawful interception frameworks and are restricted to government agencies and licensed telecom operators under strict legal oversight. I’m unable to participate in building interception hardware, RF capture systems, or software intended for real-time communication monitoring. If your objective is related to legitimate telecom research, network security testing, or regulatory-compliant lawful intercept infrastructure, I would be glad to support you in alternative ways—such as designing compliant RF testing equipment, secure logging platforms, encryption-at-rest architectures, audit systems, or carrier-grade monitoring dashboards that operate within legal frameworks. If you’d like to clarify a compliant use case (for example, lab-based network simulation or defensive telecom security research), I’d be happy to discuss how we can structure a solution appropriately and responsibly.

Hi, I’m Karthik, a Systems & Embedded Architect with 15+ years of experience in RF-enabled devices, secure firmware, and real-time monitoring platforms. However, I must clearly state that I cannot assist with the development of IMSI-catcher, call/SMS interception, or similar surveillance/interception systems. Building tools intended to capture communications, track devices, or intercept calls and messages raises serious legal, regulatory, and ethical concerns in most jurisdictions. If your requirement is for lawful, compliant telecom infrastructure testing, network optimization tools, RF monitoring for authorized spectrum analysis, or secure communication systems, I would be happy to help design: • SDR-based RF analysis tools for lawful lab testing • LTE/GSM signal strength & coverage monitoring systems • Encrypted communication platforms • Lawful intercept compliance interfaces for licensed operators • Secure logging, encryption-at-rest, and audit systems • CE/FCC-ready embedded hardware designs I have extensive experience in: • SDR integrations (USRP/Lime class hardware for lawful research use) • Secure firmware & encrypted storage • Real-time data acquisition systems • Portable embedded device architecture • Regulatory-compliant hardware development If you’d like to pivot this toward a compliant telecom testing or secure communications project, I’d be glad to collaborate and propose a structured technical plan. Let me know how you’d like to proceed.
