Different Frequency Tour Guide System
2.4GHz vs UHF Tour Guide Systems
|
UHF: ✅ Excellent wall-penetrating ability ✅ Ultra-long-range transmission of 150-200 meters ✅ Virtually no Wi-Fi interference |
2.4GHz: ✅ Global license-free use ✅ Instant activation and quick pairing ✅ Lower device cost |
🏭 Factory/Workshop Tours → UHF (Noisy environment + predominantly metal structures)
🏰 Historical Sites/Castles → UHF (Large area + multiple buildings + stone structures)
✈️ International Travel Agencies → 2.4GHz (Globally compatible, no license required)
🏢 Corporate Training → 2.4GHz (Small area + quick pairing + low cost)
🎪 Exhibitions/Events → 2.4GHz (Temporary use + rapid deployment)
🏞️ Outdoor Scenic Spots → UHF (Long-distance transmission + open space)
🏨 Hotels/Resorts → UHF (Multi-story + large area)
