General Disclaimer

The information provided by OpenLTE (“https://www.openlte.com”) is for general educational and informational purposes only. Everything on the site is offered in good faith, but we make no representation or warranty of any kind, express or implied, about the accuracy, completeness, or reliability of any calculator result, guide, or museum entry. Using the site is entirely at your own risk.

Not Engineering, Safety, or Regulatory Advice

OpenLTE is not a licensed engineering firm, a spectrum regulator, or a certification body. The path-loss, link-budget, antenna-gain, dBm-and-watt, wavelength, and Shannon-capacity calculators, along with every article and Learn entry, are educational tools that apply standard formulas and general radio-engineering knowledge. They are not a stamped design, an RF-exposure assessment, or a substitute for a qualified RF engineer, your equipment manufacturer, or your national spectrum authority.

Do not treat a computed path loss as a guarantee a link will work, a link margin as proof it is safe or legal, or an antenna length as a finished build. If a decision involves radiating power, human RF exposure, licensed spectrum, or equipment you intend to deploy, consult the appropriate qualified professional and the regulations that apply to you before acting on anything you read here.

Estimates, Not Exact Figures

The calculators use widely accepted formulas and simplifying assumptions — ideal line-of-sight propagation, lossless symmetric antenna patterns, catalogue component figures, and theoretical channel limits. They are only as good as the numbers you enter and the assumptions behind them. Real outcomes vary with terrain, obstruction, weather, multipath, interference, temperature, connector and cable condition, and equipment tolerances. Free-space path loss in particular is a best case that a real path only exceeds. Use every result as a planning aid, not a guaranteed outcome.

Radio Transmission & Safety Risk

Transmitting radio energy is regulated and can be hazardous at high power or close range. Nothing on OpenLTE tells you what you are licensed to transmit, whether an installation meets RF-exposure limits, or whether it will interfere with other users. Always:

• Check the transmit-power, bandwidth, and licensing rules for your band and region before you radiate.
• Confirm component specifications against the manufacturer’s datasheets rather than an estimate.
• Assess RF-exposure and safety limits with a qualified professional for any real installation.
• Validate a link with measurement before relying on it, and design in fade margin.
• Treat cost-of-error decisions — hardware, mast rental, spectrum — with your own due diligence.

For any question about whether a design, a power level, or an installation is safe and legal, defer to a qualified RF engineer, your equipment vendor, and your spectrum regulator over anything this site produces.

No Warranty

OpenLTE expressly disclaims all warranties, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that our tools, calculations, or information are error-free, accurate, or complete, or that the website will always be available without interruption.

Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall OpenLTE be liable for any direct, indirect, punitive, incidental, special, or consequential damages — including equipment damage, interference, regulatory penalties, or any harm arising from a design or transmission decision — related to your use of, or reliance on, our tools, guides, and information.

User Responsibility

By using OpenLTE, you acknowledge and agree that:

• You will use your own judgement, and consult a qualified RF engineer or your regulator, when applying anything here to a real system.
• You will double-check calculator inputs — values, units, and reference points such as dBi versus dBd — before relying on a result.
• You are responsible for the designs you build, the power you transmit, and the licenses you hold.
• You assume all risks associated with RF design, transmission, and installation and with the use of our tools and information.

External Links & Advertising

The site may link to third-party websites and displays advertisements from networks including Google AdSense. We do not investigate, monitor, or endorse the content of linked sites or the products in ads, and their presence is not a recommendation.
