LinkBaudLTS

LinkBaudLTS is a professional communication link analysis and link budgeting tool developed for telecommunications engineers, field technicians, students, and RF enthusiasts. The app performs comprehensive signal transmission feasibility calculations across four distinct physical media: free-space radio frequency, metallic cables, fiber optics, and aquatic environments—all on a single, free platform.

Main Features:

FSPL (Free Space Path Loss) calculation and propagation models (Friis, Okumura-Hata, ITU-R P.1546)
Analysis of metallic cables with attenuation models for skin effect, capacitance, and distributed resistance (IEC 61156, EN 50170)
Fiber optic link calculation with automatic recommendation when metallic cable is unfeasible (ITU-T G.652)
Underwater propagation analysis with acoustic and electromagnetic absorption models (ITU-R P.527)
Support for 13 industrial protocols: RS-485, CAN bus, Profibus, DeviceNet, HART, Modbus, and others (ISO 11898, CiA DS102)
Frequency profiles for drones and civilian applications (433 MHz to 5.8 GHz — ANATEL/FCC/ETSI)
Customizable baud rate with Custom field
Technical report generation in PDF with feasibility diagnosis (APPROVED / MARGINAL / REJECTED)
Trilingual interface: Portuguese, English, Spanish
Integrated technical manual with support for three languages

Based on international standards:
ITU-R P.676, ITU-R P.527, ITU-R P.1546, ITU-T G.652, IEC 61156, ISO 11898, CiA DS102, ICAO, Shannon-Hartley, Johnson-Nyquist.

No other free Android app combines RF + cable + fiber + aquatic environment + industrial protocols in a single tool. Ideal for IoT projects, industrial automation, rural telecommunications, drones, private networks and critical environments.
