Stage 0 — Image-spec reconciliation (2026-04-24)

Decision: the hero render is the canonical v1 chassis target. The original delta-from-Standard WANDERROUTER-STANDARD-5G-SPEC.md (medium chassis, internal-only cellular antenna planning) is preserved as historical reference; the v1-image-locked design is a slightly larger horizontal desktop chassis (280×200×65mm) with 6 visible external antennas, cream anodized top deck, side SIM tray + saffron eject tool, and dual front saffron indicators (general status strip + LTE indicator).

Image-locked attributes (non-negotiable v1 design constraints):

Attribute	Image-locked value
Form factor	Horizontal desktop, ~280 × 200 × 65 mm
Chassis material	Matte slate-charcoal anodized 6061 aluminum, precision-machined edges (0.5mm chamfer)
Top deck material	Cream anodized aluminum, full-coverage
Side venting	Crisp horizontal slot vents on left + right side panels only
Front face indicators	Horizontal saffron LED strip (general status, ~120mm long) + smaller saffron "LTE" indicator
External antennas	6 total: 4× Wi-Fi 7 (slim base, ~150mm) + 2× cellular (thicker base + cream identifier rings, ~170mm) — all upward-angled
SIM access	Tactile recessed SIM tray on chassis side, dual nano-SIM + eUICC
SIM-eject tool	Saffron-anodized aluminum tool, ships in box, visually distinctive
Top bezel mark	Thin saffron pinstripe horizontal along top edge of chassis sidewall (where slate meets cream)
Fans	None visible — fanless aesthetic mandatory
Aesthetic reference	Peplink Max BR1 × Cudy 5G × Teenage Engineering OD-11 × Eero Pro

Source: Michael-supplied hero image render brief (2026-04-24): "Horizontal Wi-Fi 7 router with cellular failover, roughly 280×200×65mm (slightly larger than the Standard), matte slate aluminum chassis with cream anodized top deck, SIX external antennas angled upward (four Wi-Fi antennas + two distinctly different cellular/5G antennas — the cellular pair is slightly thicker at the base with visible antenna-type identifier cream rings). A tactile recessed SIM tray on the side clearly visible with a small saffron SIM-eject tool resting beside the router on the backdrop. Front face shows a horizontal amber saffron LED strip plus a second smaller saffron indicator showing 'LTE' status. Visible ventilation slots along the sides. Thin amber saffron pinstripe along the top bezel edge."

Reconciliation actions taken (silent change avoided — every change documented):

1. Original "Medium chassis (same as Standard)" → v1 horizontal desktop 280×200×65mm (~10% larger volume than Standard). Drives mainboard PCB sizing decision in Stage 5 (~240×170mm vs Standard's smaller PCB). 2. Original "4× cellular RP-SMA bulkheads" (rear-mount + internal antennas described) → v1 6 external antennas (4 Wi-Fi + 2 cellular), all dipole-style upward-angled, RP-SMA-mounted to chassis topside near the rear edge of the cream top deck. Cellular pair gets cream-anodized identifier rings at the base + thicker dielectric loading (visually + functionally distinct from Wi-Fi antennas). 3. Original "GNSS antenna passive (Taoglas AA.114)" → v1 keeps internal passive GNSS patch antenna mounted under cream top deck (not externalized; image shows only 6 external antennas, no GNSS stub). 4. Original color/cover (inherited Standard's polymer/CNC/Lux walnut) → v1 single-material aluminum chassis with cream anodized top deck; Lux variants apply to top-deck finish only (Lux walnut overlay, Lux engraved cream). 5. Original "front-panel display TBD" → v1 specifically NO display (clean front face per image); status conveyed via LED strip + LTE indicator + WanderOS app. 6. Original "SIM access via internal" (rear-bay tray inheritence) → v1 tactile recessed SIM tray on chassis side (image-binding); +saffron-anodized SIM-eject tool ships in box (visible in render on the desk surface). 7. Original "saffron pinstripe" (inherited Standard) → v1 explicitly along top bezel edge of sidewall (where slate aluminum meets cream top deck), 1.5mm wide, ~3mm from top edge. 8. Original "5G modem M.2 B-key" → v1 kept — Telit FN990Axx M.2 B-key card (parts library reuse from WanderCar Pro-Fleet @ $135). Replaceable card per SERVICE-FLOW; no LGA conversion. 9. Original "no integrated UPS" (Standard inheritance) → v1 keeps optional UPS module (rear bay, requires 12V power lane; same as Standard; LiFePO4 4× 18650).

Carried forward (preserved):

Telit FN990Axx primary modem; Quectel RM520N-GL alternate-source (Perplexity-validated 2026-04-24 selection)
Dual nano-SIM + multi-profile eUICC (5-10 default; 10-20 with premium eUICC option) per _ESIM-MULTI-CARRIER.md

Optional mmWave (n258/n260/n261) daughterboard
Dual-mode architecture (Mode 1 / 2 / 3) per _STANDALONE-AND-PLATFORM-INTEGRATION.md
Community Pool 60/30/10 revenue split (Layer 1 ops cap 65%; Layer 2 Ambassador-voted min 35%)
Ambassador-assembled with Signature Mark (inside-bottom-cover for v1; Lux top-deck engraving as upgrade)
7-year parts commitment
Open STL files (CC BY-SA 4.0) for wall-mount bracket + antenna tilt clips + SIM-eject tool variants
Carrier-agnostic SIM activation (bring-your-own-plan)
HAVEN preferred-gateway role when wired internet unavailable
WanderOS management plane (single pane across Standard / Standard-5G / Pro v2 / Ultra)

Stage 1 — Intake + freeze (2026-04-24)

Decision: Native SOP v2.4 design (variant SOP run from Standard with image-locking). Device ID WV-NET-ROUTER-STD-5G, revision v1.0-image-locked.

Chassis: horizontal desktop, 280 × 200 × 65 mm, slate-charcoal anodized aluminum + cream anodized top deck.
Ship target: Q2 2027 (paired launch with Standard; cellular cert may slip part of carrier launch to Q3-Q4 2027).
SKU strategy: 1 chassis, 2 SKU codes (5G primary + 5G-WB wired-backhaul-default config).
Validation references: Michael's apartment cellular-primary scenario + rural-household T-Mo-replacement scenario + HAVEN cellular-primary safehouse scenario + snowbird seasonal-residence multi-eSIM scenario.
Target price span: $349 (WB variant Standard config) → $769 Lux mmWave + 2TB NVMe + walnut top.

Stage 2 — Component selection (2026-04-24)

Full BOM at BOM-normalized.csv. Key architectural decisions follow.

Wi-Fi 7 SoC: MediaTek MT7988A (preferred — UNIFIED with Router Standard)

Why: same SoC as Router Standard parent SKU. Shared BSP across the Wi-Fi 7 router family. ~$18 vol-1k. OpenWrt mainline. 2× PCIe 3.0 x1 lanes available — one for client Wi-Fi 7 radio, one for backhaul Wi-Fi 7 radio.
Considered + rejected:
Qualcomm IPQ9574 — flagship Wi-Fi 7 SoC, more performance headroom, but closed-driver concerns, higher BOM (~$32), and breaks Standard-platform unification. Rejected.
MediaTek Filogic 880 (MT7988D) — premium variant, +$8, no clear benefit for Standard-5G volume. Rejected; reserve for Pro v2 if needed.
Source: Standard spec Stage 2 decision (already canonical in ../router_standard/DECISIONS.md).

Wi-Fi 7 radios: 2× MediaTek MT7996AX dual-radio (UNIFIED with Standard)

Client radio: MT7996AX tri-band module ~$38 vol-1k.
Backhaul radio: MT7996AX tri-band module ~$38 vol-1k.
MLO posture: ✅-optional, NOT platform-guaranteed (per _VALIDATION-2026-04-24.md). Fall-back to single-link Wi-Fi 7 if MLO is unstable in field.
Antennas: 4× Wi-Fi external dipole RP-SMA on cream top deck (image-locked) — slim base, ~150mm tall.

Cellular modem: Telit FN990Axx M.2 B-key (PRIMARY) — parts library reuse from WanderCar

Why: already in WanderCar Pro-Fleet BOM at $135 vol-1k (parts library reuse). Perplexity-validated 2026-04-24: holds explicit AT&T + FirstNet + T-Mobile US + Verizon + FCC + IC + RED + PTCRB certifications — strongest US carrier pass-through. Sub-6 5G NR Cat-20 (Cat-22 in some variants), integrated GNSS, GSMA SGP.22 RSP native support.
M.2 B-key form factor: user-replaceable card via documented DIY swap procedure (per SERVICE-FLOW). Allows future cellular-modem upgrade (5G Adv → 6G transition) without chassis replacement. Stage 5 includes thermal-tuning fixture validation if alternate Quectel card is swapped.
Cost: ~$135 vol-1k (matches WanderCar Pro-Fleet entry). Subject to direct Telit FAE inquiry for Router-family aggregated volume.
Considered + rejected:
Quectel RM520N-GL — confirmed T-Mobile + FCC/IC/GCF/PTCRB but doesn't explicitly list AT&T + Verizon (per Perplexity 2026-04-24). Carrier marketing risk for "carrier-agnostic" claim. Rejected as primary; kept as alternate-source secondary for supply resilience.
Simcom SIM8202G — tertiary fallback if both Telit + Quectel hit supply issues. Not currently in BOM.
LGA-soldered modem (e.g., Telit FN990AxxA LGA variant) — would lower cost ~$10 + simplify thermal but eliminates user-replaceability. Rejected per Standard 2 (user-upgradability).
Source: parts library parts.db row for Telit FN990Axx (already at $135 in WanderCar Pro-Fleet) + _VALIDATION-2026-04-24.md Perplexity finding.

Cellular antennas: 2× Taoglas multi-band 5G dipole (image-locked external)

Part: Taoglas TG.30.8113 5G NR Sub-6 (600 MHz – 6 GHz) external dipole, RP-SMA, ~$14 each at vol-1k.
Form factor: distinctly thicker base (image-binding) — Taoglas TG.30 family has wider dielectric loading at the base for low-band (n71/n5) coverage. Visually differentiated from Wi-Fi antennas.
Cream anodized identifier rings: custom 4mm cream-anodized aluminum collar machined onto antenna base — purely visual differentiation per image. Manufactured by chassis vendor at antenna assembly time. ~$1.50/antenna.
MIMO: 2× cellular antennas = 2×2 MIMO for n71 / n41 / n77 / n78. ⚠ note: 4×4 MIMO would require 4× cellular antennas which violates image binding. Stage 0 image-spec reconciliation: 2×2 MIMO cellular accepted as v1; 4×4 MIMO is a Pro/Ultra differentiation.

Wi-Fi antennas: 4× external dipole, RP-SMA, image-locked

Part: Taoglas TG.55.8112 Wi-Fi 7 dual-band external dipole, RP-SMA, ~$8 each at vol-1k.
Form factor: slim base (image-binding) — visually distinct from cellular antennas. ~150mm tall, dipole.

GNSS antenna: internal passive patch (under cream top deck)

Part: Taoglas AA.114 passive GNSS patch, ~$4 vol-1k (same as original spec).
Mounting: internal, under cream anodized top deck (cream anodize is not a Faraday barrier at GNSS L1/L5 frequencies — passive patch performs adequately). ⚠ Stage-6 GNSS sensitivity verification.
Source: GNSS receiver is integrated in Telit FN990Axx; patch antenna feeds the dedicated GNSS RF input.

eSIM eUICC: IDEMIA Essential 10-profile (default Traveler tier)

Part: IDEMIA Essential eUICC chip (GSMA SGP.22 Consumer RSP v2.5+), ~$2.50 vol-1k.
Standard configurator default: 5-profile basic; Traveler tier upgrades to 10-profile (+$10 retail); Global tier upgrades to 20-profile (+$25 retail) via premium IDEMIA / Thales Gemalto chip.
LPA software: open-source lpac integrated into WanderOS (per _ESIM-MULTI-CARRIER.md). Commercial LPA from Thales/IDEMIA at ~$0.50/unit licensed if open-source compatibility gaps emerge in Stage 4.

SIM holder: Hirose IX-SIM dual nano-SIM + eUICC + side-tray bracket

Part: Hirose IX-SIM holder (~$3 vol-1k) on side-mount tactile-eject bracket — image binding (recessed SIM tray on chassis side, finger-friendly, no SIM tool required for SIM card insertion; nano-SIM card click-in / push-eject).
Saffron-anodized SIM-eject tool ships in box: custom WanderVerse-machined aluminum eject pin, anodized in saffron tone, ~$0.40 vol-1k. Visually distinctive on a desk (per image render). Open-STL alternate available for community remix.

RAM, storage, RJ45 magjacks, SoC PMIC, etc.

All inherited from Standard parent spec — see BOM-normalized.csv for full enumeration. Standard-5G shares ~85% of BOM rows with Standard at the platform level; cellular-specific rows (modem, eUICC, cellular antennas, SIM holder + tool) are the delta.

Saffron LED indicators (front face)

Status strip: array of 24× saffron-amber 0603 LEDs (Cree CLM3C-AKA, ~$0.12/unit × 24 = $2.88) behind a continuous opal-acrylic light-pipe diffuser (Bivar custom 120×3mm, ~$1.20 vol-1k). Driven by MT7988A GPIO via DMN2215U MOSFET array, PWM-modulated. Total LED indicator BOM ~$4.50 inc. driver.
LTE indicator: single Cree CLM3C-AKA + Bivar LP4-100 4mm round light-pipe + DMN2215U MOSFET. ~$0.70 inc. driver.
Color spec: ~592nm wavelength, color-matched to saffron pinstripe (same colorimeter spec as Bridge Full ⚠ Stage-5 LED part matching).
Engraved "LTE" label: post-anodize CO2 laser-etch on slate chassis sidewall front face, beside LTE indicator aperture.

Saffron pinstripe (top bezel edge)

Decision: anodize-masked cream-with-saffron-stripe single-anodize process (Method A), inherits Bridge Full vendor outcome (Pioneer Metal Finishing IL or Anoplate NY; ⚠ Stage-5 anodizer RFQ same as Bridge Full).
Width: 1.5mm pinstripe, ~3mm from top edge of chassis sidewall (where slate aluminum meets cream top deck).
Color spec: match LED amber-saffron at ~592nm wavelength visual (same as Bridge Full).

Internal aluminum heatspreader

6061-T6 sheet, ~180×120×3mm, couples MT7988A + Wi-Fi radios + Telit FN990Axx + PMICs to chassis top deck via thermal pads (3M 5590H + 5590H-thicker on FN990Axx LGA section). Ensures top-deck cream anodize works as primary heat-rejection surface (~25-30W via top deck, ~20-25W via side vents).

Power: 12V external brick (mandatory for 5G)

Decision: 12V 60W external brick for Standard config (vs Standard's 12V 36W or PoE option). 5G TX bursts can exceed 50W instantaneous; PoE-at sustained budget (25W) is insufficient. PoE option dropped from Standard-5G configurator.
Brick: Mean Well GS60A12-P1J 60W 12V external desktop brick, ~$22 vol-1k (UL/CE/FCC/DoE-VI cert).
Ultra-config option: UPS module (LiFePO4 18650 4-cell pack) for 3-hour standby — same as Standard.

Saffron pinstripe + cream anodize + chassis manufacturing

Inherits Bridge Full Stage 5 manufacturing path: prototype CNC, mid-run sheet-metal-bent + welded + machined edges, high-run sheet-metal stamped + machined. First-run target: 250 units at mid-run pricing. ~$185 FOB platform → $399 retail Standard config = 54% gross margin (better than Bridge Full 44% because higher retail floor; cellular modem is high-value content).

Stage 3 — Compatibility review (2026-04-24)

50-part BOM (full list BOM-normalized.csv) verified electrically + mechanically coherent. Full output: COMPATIBILITY.md.

Resolved:

MT7988A ↔ MT7996AX × 2 via PCIe 3.0 x1 each (standard Standard inheritance)
MT7988A ↔ Telit FN990Axx via PCIe 3.0 x1 (third PCIe lane); modem M.2 B-key socket on mainboard
Hirose IX-SIM dual nano-SIM holder ↔ side-tray bracket mechanical fit (260mm wide chassis allows side-tray on left side without crowding mainboard)
6 external antennas ↔ chassis top deck RP-SMA bulkhead pattern: 4 Wi-Fi (front-row, slim base), 2 cellular (rear-row, thicker base + cream rings) — total 6 RP-SMA cutouts in cream top deck near the rear edge
Internal passive GNSS patch antenna ↔ cream top deck radio-transparency: cream anodize Type II Class 2 has negligible attenuation at GNSS L1 (1575 MHz) / L5 (1176 MHz). ✅
LED strip + LTE indicator front-face apertures ↔ slate chassis precision-machined cutouts + light-pipe alignment

Deferred / open:

🟡 Telit FN990Axx 2026 distributor stock at higher Router-family aggregated volume ⚠ Stage-4 Telit FAE RFQ
🟡 OpenWrt mainline support level for FN990Axx (libqmi / libmbim) on MT7988A — verify in WanderCar Pro-Fleet integration test
🔴 Saffron-pinstripe 2-tone anodizing — inherits Bridge Full RFQ outcome
🟡 mmWave daughterboard antenna placement (rear chassis cutout, directional high-gain panel) — Stage-5 DFA
🔴 5-carrier PTCRB cert in parallel — Stage-7 budget + timeline
🔴 Production origin (US vs Taiwan CM) — gates EVT, business decision

Stage 4 — Sourcing (Perplexity-deferred)

Same posture as Bridge Full: training-knowledge architectural review; Stage-4 Perplexity RFQ verification queued for next session.

⚠ needs validation flagged on:

Telit FN990Axx aggregated volume pricing (5k+ units across Router family + WanderCar) — direct Telit FAE
Quectel RM520N-GL secondary-source pricing
mmWave daughterboard vendor (Quectel RM530N-GL is mmWave-capable; ~$220 vol-500)
IDEMIA Essential eUICC distributor channel + premium 20-profile chip cost
Saffron-anodized SIM-eject tool machining cost at vol-1k
US CM aggregate quote across Router family (Standard + Standard-5G + Pro v2 + Ultra all share PCBA pipeline)

Stage 5 — DFM/DFA/DFT (2026-04-24)

Full output: DFM-DFA-DFT.md.

Key decisions:

Mainboard: 6-layer ENIG, 240×170mm. Prototype via JLCPCB; mid-run via Sierra Circuits or Advanced Circuits.
18-step Ambassador-station workflow, 18-25 min/unit (more than Bridge Full's 12-22 because cellular antenna assembly + tuning fixture).
DFT: 18 test points, 16-test automated fixture (RF chamber for cellular + Wi-Fi 7 + GNSS), 240s/unit (longer than Bridge Full because more RF coverage).
First-run target: 250 units, ~$185 FOB platform Standard config, $399 retail Standard = 54% gross margin.
Antenna tuning fixture: required for SAR pre-scan + cellular MIMO calibration per-unit (Stage 5 fixture investment ~$8k).

---

Stage 6 — Thermal/EMC/ESD (2026-04-24)

Full output: THERMAL-EMC.md.

Key decisions:

Fanless mandatory (image-binding). Aluminum chassis + cream top deck dual-surface heatspreader.
Standard config (Wi-Fi 7 dual-radio + 5G Sub-6 light load, 25°C ambient) ~25W chassis-internal → comfortable.
Power config (Wi-Fi 7 + sustained 5G TX + mmWave daughterboard, 25°C ambient) ~55W chassis-internal → at envelope; advisory at >30°C ambient.
HAVEN config (Power + UPS charging) ~70W chassis-internal worst-case → advisory at 25-30°C ambient only.
EMC stack: standard 5G + Wi-Fi 7 host design (per-port magjack ESD + chassis bond + RF shielding cans on Wi-Fi radios + Telit modem).
ESD: Level 4 on all external I/O.
SAR pre-scan: required for 6-antenna external array — Stage 6 + Stage 7 cert path.
FCC Part 15 B Class B (residential) — image-locked aesthetic supports residential use case.

---

Stage 7 — Compliance (2026-04-24)

Full output: COMPLIANCE.md.

Headline cert budget: ~$140-200k for full 5-carrier US launch + EU + UK + Canada.

FCC Part 15 Subpart E (radio host) ~$8-12k
FCC Part 22/24/27 (cellular host) ~$10-15k
PTCRB per-carrier (5 paths in parallel): AT&T $20-30k, T-Mobile $20-30k, Verizon $20-30k, US Cellular $15-25k, FirstNet (via AT&T) $5-10k incremental = $80-125k total
CE RED + UKCA + ISED ~$8-12k combined
UL 62368-1 ~$15-25k (mains-connected external brick = inherited Mean Well component cert; product-level still required)
FCC SAR (host) ~$8-12k for 6-antenna array including cellular SAR
Energy Star + RoHS / REACH / WEEE — declarations, included
DA-26-278 — Standard-5G is consumer-router class (cellular modem + Wi-Fi + WAN routing); ⚠ Stage-4 FCC FAE check assumed conservative — US CM strongly preferred
Phased launch posture: v1 ship with T-Mobile + AT&T + Verizon certs done (~$60k-$80k cert before ship); US Cellular + FirstNet adjudication post-ship (Q3-Q4 2027). HAVEN-config (UPS + LoRa) UL 1973 + UN38.3 cert adds ~$20k; same posture as Bridge Full.

---

Stage 8 — Canonical BOM + GUIDE + STLs (2026-04-24)

BOM-platform.csv (in every Standard-5G), BOM-modules.csv (configurator-driven), GUIDE.md (rack/desk install + eSIM activation + dual-SIM + failover behavior + Matter commissioner role + Bridge Mini fleet integration), STL-OPEN-FILES/README.md (wall-mount bracket + antenna tilt clips + SIM-eject tool variants + dust covers + cable rake).

---

Stage 9 — HW↔FW (2026-04-24)

Full output: HW-FW.md.

OpenWrt 24.10 base + WanderOS-Bridge-5G overlay (shared codebase with Standard, per-SKU feature flags).
Wi-Fi 7 driver mt76 for MT7996AX (mainline OpenWrt 24.10 ⚠ MLO maturity — soft-fall-back to single-link).
Cellular driver: ModemManager + libqmi + libmbim for FN990Axx (mainline; reused from WanderCar Pro-Fleet).
eSIM LPA: open-source lpac integrated with WanderOS eSIM Manager UI.
One firmware image, runtime hardware discovery (modem class + SIM/eUICC + mmWave daughterboard).
Secure boot via U-Boot signed bootloader + dual-partition rollback.
16-test production bring-up (vs 14 for Bridge Full — adds cellular link-state + GNSS fix-quality + dual-SIM + eUICC handshake + LTE indicator color-match coverage).

---

Stage 10 — Gate review + service flow (2026-04-24)

GATE.md (EVT 2026-Q4, DVT 2027-Q1, PVT 2027-Q2) + SERVICE-FLOW.md (rack/desk-friendly send-back procedures + user-replaceable modem M.2 card + user-replaceable antennas + Ambassador refurb + 5-carrier-cert phased launch).
