A case can reduce your exposure in real use—if it follows first principles and if <em>you</em> use it correctly. This post explains why <strong>TruthCase™</strong> exists, what a case can (and cannot) do, why “99% protection” claims are misleading, and how the <strong>Truth Roadmap</strong> moves us toward everyday ~99% reductions (design + habits + Li‑Fi + policy).</p> <hr class="rf-hr" /> <h2 id="why">Why We Built a TruthCase (and Why the Name Matters)</h2> <div class="rf-callout"> <p class="rf-kicker">The problem we set out to solve:</p> <p>Most “anti‑radiation” cases on the market today make <strong>first‑principles design mistakes</strong>—features like <strong>metal loops</strong>, <strong>magnetic detachable wallets/plates</strong>, <strong>large, unshielded ear‑side apertures</strong>, and <strong>over‑shielding/extra thickness near antenna zones</strong>. These design choices can <strong>detune or obstruct antennas</strong>, prompting phones to <strong>automatically increase their transmit power</strong> to stay connected—undermining the very goal of reducing exposure. :contentReference[oaicite:0]{index=0}</p> <p><strong>TruthCase™ exists to exclude those exposure‑increasing features on purpose</strong> and to teach how to use a case in a way that aligns with how radios actually work.</p> </div> <p><strong>Phones adjust their power.</strong> All modern cellular systems use <em>power control</em>—if the link is obstructed or the signal is weak, the phone may transmit more strongly to maintain quality. That’s why good design aims to keep antennas efficient and unblocked, and good habits aim to keep distance and reduce needless duty cycle. :contentReference[oaicite:1]{index=1}</p> <blockquote class="rf-quote">A case shouldn’t fight the radio. It should protect the person—without provoking a power boost.</blockquote> <hr class="rf-hr" /> <h2 id="what-a-case-can-do">What a Case Can Do (and What Only System Change Can Do)</h2> <div class="rf-table"> <table> <thead> <tr><th></th><th>TruthCase™ (Exposure‑Reduction Case)</th><th>System‑Level Changes</th></tr> </thead> <tbody> <tr> <td><strong>Goal</strong></td> <td>Lower near‑body RF exposure in everyday use</td> <td>~99% everyday reduction</td> </tr> <tr> <td><strong>How</strong></td> <td>Directional shielding (between you & phone); antenna‑aware layout; thin build; clear habits</td> <td>Li‑Fi for zero‑SAR indoor data links; better guidance defaults; modernized policies</td> </tr> <tr> <td><strong>Limits</strong></td> <td>Does <em>not</em> eliminate RF while the phone transmits</td> <td>Requires adoption in devices/venues and enabling policy updates</td> </tr> </tbody> </table> </div> <p class="small rf-muted"><strong>Why this split matters:</strong> Case design + habits reduce exposure now. The leap toward ~99% routine reduction comes from moving high‑volume indoor traffic to light‑based links (Li‑Fi) and shifting policy so lower‑RF defaults are available.</p> <hr class="rf-hr" /> <h2 id="99-myth">The “99% Protection” Myth—And the Truth Instead</h2> <div class="rf-warning"> <p><strong>Myth:</strong> If a fabric swatch blocks “99%” in a lab, then a phone case delivers “99% protection” everywhere.</p> <p><strong>Truth:</strong> Real‑world exposure depends on <em>orientation</em> (shield between you & the phone), <em>antenna performance</em> (no metal/magnets/obstructions), <em>usage</em> (calls vs. idle), and <em>duty cycle</em> (how much the radio transmits). Swatch percent ≠ life percent.</p> </div> <p>There’s also a second problem: <strong>cases that obstruct antennas can increase transmit power</strong>, potentially raising exposure—the opposite of the marketing promise. Independent coverage has raised this concern for years, including analyses noting that badly designed cases can force phones to work harder to maintain a link. :contentReference[oaicite:2]{index=2}</p> <hr class="rf-hr" /> <h2 id="first-principles">First‑Principles Truth Standard™</h2> <div class="rf-table"> <table> <thead> <tr><th>Principle</th><th>What it means</th><th>What TruthCase™ excludes on purpose</th></tr> </thead> <tbody> <tr> <td><strong>Directional shielding in use</strong></td> <td>Place the shield <em>between your body and the phone</em> for calls, pocket carry, and long scrolling.</td> <td>No “everywhere” claims; it’s about placement when it matters.</td> </tr> <tr> <td><strong>Antenna‑aware layout</strong></td> <td>Keep antennas efficient so the phone can use <strong>lower transmit power</strong> for the same connection. :contentReference[oaicite:3]{index=3}</td> <td><strong>No metal loops</strong>, <strong>no magnetic plates</strong>, <strong>no thick stacks near antenna zones</strong>. :contentReference[oaicite:4]{index=4}</td> </tr> <tr> <td><strong>Shielding continuity at the ear</strong></td> <td>Avoid large, unshielded apertures aligned with the ear.</td> <td>No big ear‑side speaker cutouts that break the shield.</td> </tr> <tr> <td><strong>Field behavior > fabric %</strong></td> <td>Judge by device behavior and near‑body conditions, not just swatch numbers.</td> <td>No “99% everywhere” marketing.</td> </tr> <tr> <td><strong>Verifiable materials</strong></td> <td>Let users confirm a conductive shield path.</td> <td>TruthCase™ includes an <strong>ohmmeter access point</strong> for continuity checks.</td> </tr> <tr> <td><strong>Clear, honest habits</strong></td> <td>Teach calls, pocket orientation, night distance, airplane‑mode options.</td> <td>No vague or “magic shield” guidance.</td> </tr> </tbody> </table> </div> <hr class="rf-hr" /> <h2 id="detuning">Why Design Mistakes Backfire (Metal, Magnets, Over‑Shielding)</h2> <h3>1) Metal loops & decorative metal near antennas</h3> <p>Metal close to antennas can <strong>detune</strong> or alter resonance and reduce radiation efficiency. Designers have documented performance degradation and coupling challenges in metal‑frame/metal‑case phones; adding extra metal hardware in a case can make this worse. :contentReference[oaicite:5]{index=5}</p> <h3>2) Magnetic detachable wallets/plates behind the phone</h3> <p>Large steel plates and magnet stacks <strong>obstruct the antenna’s view</strong>. If the phone senses a degraded link, it may increase transmit power (power control) to compensate. :contentReference[oaicite:6]{index=6}</p> <h3>3) Over‑shielding & thickness near antenna zones</h3> <p>“Wrap it all in foil” or piling cards/material near key antenna areas can <strong>degrade efficiency</strong>—again, prompting higher transmit power to maintain the link. Real‑world reports and tests have noted case‑related attenuation and behavior changes. :contentReference[oaicite:7]{index=7}</p> <h3>4) Large, unshielded ear‑side apertures</h3> <p>A big opening aligned with the ear breaks shielding continuity—especially relevant at higher bands with shorter wavelengths—reducing the benefit of directional shielding on calls.</p> <hr class="rf-hr" /> <h2 id="how-phones-behave">How Phones Actually Behave (and Why Your Habits Matter)</h2> <ul class="rf-list"> <li><strong>Power control:</strong> Cellular systems (e.g., CDMA/UMTS/LTE/NR) use fast and slow power control so each device transmits just enough to maintain the target link quality. Obstruct the path and the phone can transmit more strongly. :contentReference[oaicite:8]{index=8}</li> <li><strong>Weak signal → higher exposure:</strong> Observational research shows measured exposures are typically lower with strong signal and higher with poor signal or obstructed paths. :contentReference[oaicite:9]{index=9}</li> <li><strong>Distance helps:</strong> Field strength drops with distance. Even small increases (speaker mode, wired headset) can matter day to day.</li> </ul> <div class="rf-info"> <p class="rf-kicker">TruthCase™ usage basics:</p> <ul class="rf-list"> <li><strong>Calls:</strong> Start/answer, then close the shielded cover toward your head (shield between you & phone). Prefer speaker or wired for long calls.</li> <li><strong>Pocket:</strong> Carry with the <em>shielded cover toward your body</em> (back pocket often best).</li> <li><strong>Night:</strong> Increase distance or use airplane mode; don’t park the phone by your head.</li> <li><strong>Verify:</strong> Use an <kbd>ohmmeter</kbd> on the access point—continuity confirms a conductive shield path.</li> </ul> </div> <hr class="rf-hr" /> <h2 id="truth-roadmap">The Truth Roadmap — Fixing a 140‑Year Habit of Using Radio for Everything</h2> <p>We’ve spent ~140 years optimizing wireless radio—from early Hertzian experiments to today’s dense, multi‑band, multi‑antenna smartphones.
