Precision Tools for
Wireless Professionals
Plan, calculate, and deploy outdoor wireless links with confidence. LinkZoneTools gives engineers and network planners the professional-grade tools they need — all in one platform, from anywhere.
Plan a Wireless Link
From GPS coordinate lookup to full path profile analysis — LinkZoneTools brings professional RF engineering tools to your browser, no software installation required.
GPS & Satellite Map Tool
Enter GPS coordinates for any two locations on Earth and visualize them on an interactive satellite map. View link paths, terrain, and site relationships instantly.
IncludedPath Profile & Line of Sight
Generate a complete terrain path profile between two GPS points. Identify obstructions, determine antenna height requirements, and verify line-of-sight clearance.
ProFresnel Zone Calculator
Calculate the first Fresnel zone radius at any point along a link path for any frequency band. Ensure adequate clearance for reliable, interference-free transmission.
ProFree Space Path Loss (FSPL)
Compute free space path loss for any frequency and link distance using the standard ITU-R formula. Essential for link budget planning and system design.
IncludedITU Rain Zone Lookup
Input any GPS coordinate on Earth and instantly retrieve the correct ITU rain zone designation (A through Q) along with the corresponding rainfall rate in mm/hr.
IncludedLink Budget Calculator
Combine EIRP, FSPL, cable losses, antenna gain, and receiver sensitivity into a complete end-to-end link budget. Determine fade margin and system reliability.
ProWireless Link Calculator
All-in-one wireless product link calculation tool. Input your equipment specs and distances to determine signal levels, data rates, and link feasibility at a glance.
ProUnit & Frequency Converter
Quickly convert between dBm and watts, feet and meters, miles and kilometers, GHz and MHz. Antenna beamwidth and wavelength calculations also included.
IncludedCreate Your Account
Sign up in seconds. Choose a monthly or annual plan that fits your team's needs with no contracts required.
Enter Your Link Data
Input GPS coordinates, frequencies, and equipment specs. Our tools handle the rest — no manual formula lookup needed.
Analyze & Visualize

Every calculation in LinkZoneTools follows published ITU-R recommendations. Here's what powers the math:
ITU-R P.838
Rain attenuation model used in our rain zone lookup and link reliability calculations. Maps any GPS coordinate to a specific rain zone (A–Q) with corresponding rainfall intensity in mm/hr.
ITU-R P.525
Free Space Path Loss formula: FSPL (dB) = 20·log₁₀(d) + 20·log₁₀(f) + 92.45 (for km and GHz). Used in all link budget tools.
Fresnel Zone (Standard)
First Fresnel zone radius: r₁ = 17.3·√(d₁·d₂ / f·d) where d₁, d₂ are distances from each end in km, f is frequency in GHz, and d is total path length in km.
