🔬 Data Speaks Louder: A Deep Dive into Arad Connectivity's Module-to-Module Long-Range Test Data
Following our previous smartphone-to-module evaluation, our R&D team has just completed high-standard Module-to-Module (Bi-directional Peer-to-Peer) long-range testing for the MN54LM-20A series. This dataset provides concrete proof of how symmetric RF architectures unlock unprecedented communication distances and stability!
📊 Key Distance Data & Field Test Insights:
Extreme Line-of-Sight (LOS) Range:
When pairing two symmetric, high-performance modules in an open-space environment, the MN54LM-20A achieved rock-solid bi-directional peer-to-peer links exceeding 1,000 meters, fully unleashing the massive link budget potential of the SoC.
Performance Variance Across Form Factors:
Standard / External Antenna Variants: Delivered maximum unobstructed range, ideal for large-scale outdoor and industrial deployments.
Ultra-Compact Footprints (e.g., MN54LM-S20A at 7.5x10.2mm): Naturally bounded by size constraints and antenna aperture, yet empirical rotation optimizations (such as axis-angle tuning) enabled these micro-modules to maintain hundreds of meters of stable connectivity—proving our successful balance between miniaturization and RF integrity.
Module-to-Module vs. Smartphone-to-Module Comparison:
Our prior smartphone test (iPhone 7 at 1M PHY) capped out between 370–660 meters, primarily constrained by the smartphone's limited TX power (~0 dBm) and consumer-driven internal antenna layout acting as the system bottleneck.
By removing the smartphone constraint in this module-to-module test, both sides leveraged symmetrical high output power (up to +8 dBm) and superior receiver sensitivity (-103 dBm at 125kbps), resulting in a massive leap in operational range and fading margin.
💡Takeaway:
Identifying and eliminating RF system bottlenecks is vital for robust IIoT architecture. If your application demands uncompromised, long-range peer-to-peer reliability independent of consumer devices, Arad Connectivity's MN54LM-20A series is engineered to deliver.

🔬 從數據看本質：愛瑞德科技 MN54LM-20A「模組對模組」長距離極限測試與距離數據深度解析
繼上次公布「模組對智慧型手機」的測試後，我們近期完成了針對 MN54LM-20A 系列模組 的高規格 「模組對模組（Module-to-Module）」雙向長距離點對點實測。這次的數據清楚揭示了當雙方皆具備優化射頻架構時，通訊距離與穩定度的突破性展現！
📊 核心距離數據與實測表現：
極限視距（LOS）傳輸距離：
在雙方皆配置高功率與對稱射頻設計的環境下，MN54LM-20A 在開放場域的雙向點對點測試中，成功實現了超越 1,000 公尺甚至更遠 的穩定鏈結，徹底展現 Nordic nRF54LM20A SoC 在鏈結預算（Link Budget）上的極致潛能。
不同封裝與天線配置的數據差異：
標準板載天線 / 外部天線款： 展現出最佳的無障礙傳輸距離，能輕鬆應對大型戶外或廠域的大範圍布署。
超微型封裝款（如 MN54LM-S20A，7.5x10.2mm）： 雖然受限於微型化機構與天線孔徑，但在點對點實測中依然保持了高水準的表現。透過旋轉優化（例如軸向角度微調），即使在微型尺寸下也能穩定維持數百公尺的有效通訊，證明了我們在微型化與射頻效能之間的完美平衡。
對比先前「手機對測」的關鍵差異：
先前模組對手機（iPhone 7，1M PHY）的極限大約落在 370–660 公尺 之間，主因在於手機端的發射功率（TX Power 約 0 dBm）與內置天線受限，成為系統中的「短板」。
而本次「模組對模組」的對測解除了手機端的功率限制，雙向高功率（高達 +8 dBm）與優化靈敏度（125kbps 下達 -103 dBm）火力全開，讓通訊距離與抗衰減能力迎來倍數級的躍升。
💡 總結：
了解系統中「誰是鏈結短板」是工業物聯網（IIoT）架構設計的關鍵。如果您正在尋找不受消費性行動裝置限制、能提供穩定且長距離可靠連線的硬體方案，愛瑞德的 MN54LM-20A 絕對能滿足您最嚴苛的需求。
