📡 Router and WiFi Extender Placement System

[TangoEcho]

Feature Implementation Complete ✅

Successfully implemented a comprehensive router and extender placement system with AR visualization.

Features Implemented

Core Functionality

• Router Placement: Tap-to-place interface in AR with realistic 3D router model
• Surface Detection: Analyzes RoomPlan furniture data to find suitable tables/counters
• Smart Extender Placement: Automatically places extenders on optimal surfaces based on:
  • Furniture type (tables preferred over sofas)
  • Height constraints (waist-height ideal)
  • Surface area and confidence scores
  • RoomPlan detection confidence

3D Visualization (AR)

• Realistic Device Models: Custom SceneKit models with detailed geometry
  • Router: Main body, antennas, LED indicators, ventilation grilles
  • Extender: Compact design, power prongs, WiFi signal indicators, Ethernet ports
• Visual Effects: Pulsing LED animations, device highlighting, connection lines
• Interactive Labels: Billboard-constrained labels with emoji icons

Floor Plan Integration (2D)

• Device Symbols: Router (📡) and extender (📶) symbols with colored circles
• Connection Lines: Animated lines showing router-extender relationships
• Confidence Indicators: Visual feedback on placement confidence
• Professional Layout: Clean integration with architectural floor plans

Technical Architecture

New Components Added

1. NetworkDeviceManager.swift (272 lines)

   • Device placement logic and surface analysis
   • Suitability scoring algorithm
   • Device state management

2. NetworkDevice3DModels.swift (292 lines)

   • Detailed 3D model creation with SceneKit
   • Device labeling system
   • Visual effects and animations

Enhanced Components

• ARVisualizationManager: Added network device rendering (~200+ lines added)
• RoomCaptureViewController: Router placement UI and gesture handling
• FloorPlanViewController: 2D device symbol rendering system

Usage Workflow

1. Room Scanning: Complete room capture using RoomPlan
2. Surface Analysis: System analyzes detected furniture for extender placement
3. Router Placement: User taps "Place Router" and taps location in AR
4. Automatic Extender: System places extender on best available table
5. Visualization: Devices shown in both AR view and floor plan

Technical Specifications

• Minimum Height: 0.5m (extender placement)
• Maximum Height: 2.0m (extender placement)
• Preferred Surfaces: Tables > Counters > Sofas
• Scoring Algorithm: Combines furniture type, height, surface area, and confidence
• 3D Models: Realistic proportions with detailed materials and lighting

Future Enhancements (Not Yet Implemented)

• WiFi range calculation for smart placement optimization
• Multiple extender support
• Signal strength visualization
• Coverage area overlays
• User-adjustable extender placement
