Brief
WanderAway is a privacy-first, repair-friendly, identity-aware emergency beacon + satellite tracker that:
- Works without a subscription at the Lite + Trail tiers via LoRa mesh + Meshtastic-compatible open protocol (category-defining)
- Provides Iridium-network SOS + 2-way messaging at the Expedition + Ultra tiers, routed through GEOS IERCC (same rescue-dispatch path as Garmin inReach)
- Survives IP68 submersion + MIL-STD-810G shock/vibration + -40 to +70 °C operation
- Supports survivor safe-passage protocols (pre-shared trust contacts only, never broadcast) for trans, undocumented, queer-traveler use cases unaddressed by Garmin / ZOLEO / SPOT
- Is user-repairable (swappable 18650 cell, captive T10 screws, published STLs + schematics) with a 7-year parts commitment
- Is Ambassador-assembled + Ambassador-signed under the 60/30/10 PrideFund flow

Who we serve (design pillars)
1. Survivors + undocumented + trans + queer travelers: safe-passage protocol, pre-shared trust contacts, covert mode, duress code. The category nobody else addresses. 2. Off-grid + backcountry travelers: Garmin inReach audience + outdoors community, served with identity-aware + repair-friendly + open-protocol architecture. 3. Meshtastic / community-LoRa users: the Beacon Lite is a polished, IP68-rated, Ambassador-assembled production device that slots into existing community mesh networks. 4. HAVEN field workers + mobile-living WanderVerse users: the full Expedition Ultra pairs with WanderRouter Ultra (same Iridium-modem family) + WanderBand Ultra (LoRa mesh) + WanderNode Hub (gateway) for integrated connectivity.

Platform + module philosophy
WanderAway follows Standard 6b (platform + modules, not fixed BOM):
Platform (in every unit of its tier):
- Chassis + mainboard + power + antenna + battery + USB-C + OLED/mem-LCD + buttons + BLE + LoRa
Modules (order-time axes: see CONFIGURATOR.md):
- Satellite modem axis: none (Lite/Trail) · Iridium 9603N (Expedition) · Iridium 9670 (Ultra base) · Iridium 9670 + Astrocast (Ultra full) · add-on 406 MHz PLB (Ultra Lux)
- GNSS axis: none (Lite) · MAX-M10S L1 (Trail/Expedition/Ultra base) · ZED-F9P dual-band RTK (Ultra Lux)
- Solar axis: no solar (Lite/Trail/Expedition base) · 2 W integrated solar + sapphire cover (Expedition upgrade + Ultra base)
- Battery axis: 18650 × 1 (Lite/Trail) · 18650 × 1 or × 2 (Expedition/Ultra)
- Strap/carabiner axis: lanyard (base) · carabiner (included Expedition/Ultra) · Ambassador-made paracord (Lux)
- Chassis finish axis: standard black (base) · hi-viz orange (rescue) · forest green (low-vis) · Ambassador Lux custom
Upgrade path: Expedition can be factory-upgraded to Ultra (+solar + Astrocast + rotary encoder + extended battery). Lite cannot be upgraded to Iridium tier, different chassis + mainboard.

Dual-mode spec (per Standard 0 + `../_STANDALONE-AND-PLATFORM-INTEGRATION.md`)
Mode 1: Standalone OLED + buttons
Every tier works fully without any other hardware. Setup via on-device wizard or one-time USB-C pairing to a laptop.
- Lite/Trail: OLED + buttons walk through first-time pairing (pre-shared mesh channel key QR-code scan from manual, or USB-C pairing)
- Expedition/Ultra: mem-LCD shows menu + messaging + SOS flow self-contained
Mode 2: Phone companion app + Apple Find My + Meshtastic
- iOS app (Swift + SwiftUI): companion + Apple Find My accessory + HealthKit integration for trip-share metadata · native HomeKit / Shortcuts triggers ("leaving for the trail" → configure WanderAway)
- Android app (Kotlin + Jetpack Compose): companion + Google Health Connect + Home + Matter trigger support
- Web app (PWA): admin + trip-share + map overlay desktop-first
- Meshtastic interop: standard Meshtastic app sees WanderAway as a generic Meshtastic node; messaging, position, telemetry all flow
Mode 3: WanderNode Hub + WanderSafeMesh
- WanderNode Hub runs a RAK LoRa concentrator + acts as home-gateway for WanderAway check-ins (configurable "arrived home" triggers)
- WanderSafeMesh, the nonprofit community mesh (wanderingwithpride.org), where community-deployed, would extend mesh coverage, user's beacon can reach further
- HAVEN safehouse integration: WanderAway SOS routes through WanderNode Hub → WanderRouter Ultra → Iridium uplink when the phone is out of range

Survivor safe-passage protocol (identity-aware)
Not a marketing feature: a core product principle. Built for users the commercial emergency-device industry does not serve.
Pre-shared trust contact pattern (not broadcast)
- User designates 1-5 trust contacts at setup
- Each trust contact receives a Meshtastic channel key + Iridium routing ID via out-of-band exchange (QR code in person, secure messenger)
- Check-ins and safe-passage signals route ONLY to these pre-shared contacts via LoRa (if in range) or Iridium (if satellite tier)
- No WanderVerse cloud relay, no public API, no broadcast
- Contrast: Garmin inReach check-ins route through Garmin's servers and appear in a public-ish shareable map by default
Covert mode
- On-device UI shows a generic "Outdoor GPS" interface
- Hidden apps (SOS, trust-contact messaging, duress) accessible only via 2-button combo + PIN
- Watch face / label can be custom-printed with a decoy brand for users traveling through hostile jurisdictions
Duress code
- 2-way messaging Ultra has a keyboard: one sequence types back "all good, continuing" to a watcher while silently transmitting "duress" to trust contacts
- Check-in button can be configured as "all-good" OR "duress" based on pre-configured codes
Network-routing awareness
- Iridium SOS defaults to GEOS IERCC → local SAR (same as Garmin, appropriate for lost-hiker / medical emergency)
- Survivor safe-passage signals route to PRE-SHARED CONTACTS ONLY, never to IERCC (user doesn't want government rescue; they want a trusted human to know their location)
- User explicitly chooses channel at each event
Documentation
- Public
GUIDE.md covers non-sensitive usage; the safe-passage flow is documented in a signed-out channel for survivors to access privately

Radio architecture v2: LR2021 migration (2026-04-25)
Primary radio: Semtech LR2021 (LoRa Gen 4 / LoRa Plus). Replaces previous multi-chip radio architecture (SX1262 + nRF52840 + CC2652R7 collapsed to one).
What this unlocks
- 40× throughput: 62.5 kbps → 2.6 Mbps via FLRC modulation. Enables: image snapshots over LoRa, voice / walkie-talkie, AI-edge inference output streaming, audio classification.
- Multi-PHY in one chip: LoRaWAN + Sidewalk + Meshtastic + Z-Wave + Wi-SUN + BLE + Thread/Zigbee. Single global SKU; no regional variants required.
- Direct-to-satellite (S-band 1.9–2.5 GHz NTN), phone home from anywhere on Earth, no cell tower. Game-significant for at-risk-user use cases (DV-survivor escape from anywhere, wilderness emergency).
- -142 dBm sensitivity: best-in-class link budget (vs SX1262 -137 dBm).
Migration strategy: hybrid
This product is Tier-1 critical (life-safety / DV-survivor flagship / global-supply-chain anchor). Hybrid alt-source path retained:
- Founding-tier SKU: SX1262 + nRF52840 (proven dual-source). No FLRC voice, no satellite. Lower cost, regional-variant-required.
- Pro / Global SKU: LR2021 single-chip multi-PHY + S-band NTN. FLRC voice, satellite emergency, AI-edge inference, single global SKU.
Customer chooses at purchase. Spec tables list both with cross-references.
Cert path additions
- FCC Part 25 NTN earth-station registration, required for S-band satellite operation. Engagement budget ~$30–60k via TÜV SÜD or Element. Pro tier only.
- FCC Part 15 Subpart C: sub-GHz + 2.4 GHz emissions (existing cert covers; verify LR2021 module FCC ID propagates).
- CE / UKCA / IC / AS-NZS: international filings updated to reference LR2021 module.
Capability bullets for marketing copy
- Phone home from anywhere: direct-to-satellite, no cell tower (Pro tier)
- Multi-protocol mesh: LoRaWAN, Amazon Sidewalk, Meshtastic, Z-Wave, BLE, Thread, Wi-SUN
- Single global SKU: no US/EU regional variants
- 40× faster radio than the previous generation, in the same power envelope

**Note (Perplexity-validated 2026-04-25):** When this doc says LR2021 supports multi-PHY in one chip, the *hardware* is multi-PHY-capable, but full protocol stacks (LoRaWAN, Amazon Sidewalk, Meshtastic, Z-Wave, Wi-SUN, BLE, Thread/Zigbee) integrate via firmware layers, not all bundled native. We ship pre-built stacks for the active set per product. See `PERPLEXITY-VALIDATION-2026-04-25.md` in `_WANDERVERSE-LIBRARY/`.
