LTE 與 5G 在關鍵通訊領域的應用（2025-2030 年）—機會、挑戰、策略與預測

摘要

近一個世紀以來，關鍵通訊產業一直依賴窄頻陸地行動無線電 (LMR) 網路來提供關鍵任務語音和低速數據服務。隨著時間的推移，這些系統從相對基礎的類比無線電發展到 APCO P25 和 TETRA 等數位通訊技術，提供卓越的語音品質、端對端加密和其他高級功能。然而，由於其固有的頻寬和設計限制，即使是最先進的數位 LMR 網路也無法支援行動寬頻和數據驅動的關鍵物聯網應用，而這些應用對於公共安全、國防、公用事業、交通運輸、石油天然氣和採礦等關鍵通訊產業領域至關重要。

由 3GPP 定義的 LTE 和 5G 新空口 (NR) 空中介面已成為填補此空白的領先無線接取技術候選方案。在過去的十年裡，已經可以應對各種各樣的應用場景，包括 PTT 群組通訊、多媒體訊息傳遞、高清視訊監控、無人機超視距 (BVLOS) 操作、態勢感知、無線 AR/VR/MR (擴增實境/虛擬實境/混合實境)、協作移動機器人、AGV (自動導引車) 以及 IIoT (聯網機器人）這些網路涵蓋範圍廣泛，包括美國的第一響應者網路 (FirstNet)、韓國的國家災害安全通訊網路 (Safe-Net)、沙烏地阿拉伯的關鍵任務寬頻網路 (FirstNet)、韓國的國家災害安全通訊網路 (Safe-Net)、沙烏地阿拉伯的關鍵任務寬頻網路、英國的緊急服務網路 (ESN)、法國的未來無線電網路 (RRF)、瑞典的瑞典緊急網路 (SWEN) 和芬蘭的 VIRVE 2 公有網路 (RRF)、瑞典的瑞典緊急網路 (SWEN) 和芬蘭的 VIRVE 2 公有網路 (RRF) 公用網路 (RRF)、瑞典的瑞典緊急網路 (SWEN) 和芬蘭的 VIRVE 2 公有網路 (RRF) 公帶網路 (5G 基地架設網路）、覆蓋公用事業服務區域的區域蜂窩網路、支援未來鐵路行動通訊系統 (FRMCS) 的未來鐵路行動通訊系統網路（可實現列車與地面通訊），以及用於機場、海港、石油和天然氣生產設施、發電廠、變電站、離岸風電場、偏遠礦區、工廠和倉庫等環境中的本地無線連接的非公共網路 (NPN)。

傳統上，大多數關鍵通訊使用者組織將 LTE 和 5G NR 視為互補技術，主要利用它們來增強現有通訊系統。過去人們認為，具備寬頻功能的語音中心型陸地行動無線電（LMR）網路是主流。但隨著基於3GPP標準的MCX（任務關鍵型PTT、視訊和資料）、QPP（服務品質、優先順序和搶佔）、HPUE（高功率用戶設備）、IOPS（公共安全隔離運作）、URLLC（超可靠低延遲通訊）、TSC（時間敏感通訊）及相關服務啟用技術的商業化，這種觀念已經改變了。 LTE和5G網路如今已被公認為全面的關鍵通訊平台，並正逐步取代傳統的LMR系統，為未來的升級提供保障。此外，還有用於密集環境下 MCX 服務的 5G 多播廣播服務 (5G MBS/5MBS)、用於非網絡通信的 5G NR 側鏈、車載中繼 (VMR)、帶無線接入迴傳功能的移動 gNB (MWAB)、衛星非地面網絡 (NTN) 整合，以及在專用接入迴傳功能的移動 gNB (MWAB)、衛星非地面網絡 (NTN) 整合，以及在專用接入軌道上支持這些低頻段的公用事業能力。

預計到 2025 年，全球對關鍵任務型 3GPP 網路及相關應用的投資將達到 54 億美元。在公共安全寬頻、國防通訊、智慧電網現代化、FRMCS 和工業物聯網 (IIoT) 等計畫的推動下，預計未來三年市場將以約 19% 的複合年增長率成長，到 2028 年底將超過 92 億美元。

本報告對 LTE 和 5G 在關鍵任務型通訊中的應用進行了研究和分析。溝通交流，提供有關價值鏈、市場驅動因素、採用障礙、使能技術、管理和商業模式、垂直行業、應用場景、關鍵趨勢和未來路線圖的資訊。

Synopsis

For nearly a century, the critical communications industry has relied on narrowband LMR (Land Mobile Radio) networks for mission-critical voice and low-speed data services. Over time, these systems have evolved from relatively basic analog radios to digital communications technologies, such as APCO P25 and TETRA, to provide superior voice quality, end-to-end encryption, and other advanced features. However, due to their inherent bandwidth and design limitations, even the most sophisticated digital LMR networks are unable to support mobile broadband and data-driven critical IoT applications that have become vital for public safety, defense, utilities, transportation, oil and gas, mining, and other segments of the critical communications industry.

The 3GPP-defined LTE and 5G NR (New Radio) air interfaces have emerged as the leading radio access technology candidates to fill this void. Over the last decade, a plethora of fully dedicated, hybrid commercial-private, and secure MVNO-based 3GPP networks have been deployed to deliver critical communications broadband capabilities - in addition to the use of commercial mobile operator networks - for application scenarios as diverse as PTT group communications, multimedia messaging, high-definition video surveillance, BVLOS (Beyond Visual Line-of-Sight) operation of drones, situational awareness, untethered AR/VR/MR (Augmented, Virtual & Mixed Reality), collaborative mobile robots, AGVs (Automated Guided Vehicles), and automation in IIoT (Industrial IoT) environments. These networks range from nationwide PPDR (Public Protection & Disaster Relief) broadband platforms such as the United States' FirstNet (First Responder Network), South Korea's Safe-Net (National Disaster Safety Communications Network), Saudi Arabia's mission-critical broadband network, Great Britain's ESN (Emergency Services Network), France's RRF (Radio Network of the Future), SWEN (Swedish Emergency Network), and Finland's VIRVE 2 public safety broadband service to defense sector 5G programs for the adoption of tactical cellular systems and permanent private 5G networks at military bases, regional cellular networks covering the service footprint of utility companies, FRMCS (Future Railway Mobile Communication System)-ready networks for train-to-ground communications, and NPNs (Non-Public Networks) for localized wireless connectivity in settings such as airports, maritime ports, oil and gas production facilities, power plants, substations, offshore wind farms, remote mining sites, factories, and warehouses.

Historically, most critical communications user organizations have viewed LTE and 5G NR as complementary technologies, used primarily to augment existing voice-centric LMR networks with broadband capabilities. This perception has changed with the commercial availability of 3GPP standards-compliant MCX (Mission-Critical PTT, Video & Data), QPP (QoS, Priority & Preemption), HPUE (High-Power User Equipment), IOPS (Isolated Operation for Public Safety), URLLC (Ultra-Reliable, Low-Latency Communications), TSC (Time-Sensitive Communications), and related service enablers. LTE and 5G networks have gained recognition as an all-inclusive critical communications platform and are nearing the point where they can fully replace legacy LMR systems with a future-proof transition path, supplemented by additional 5G features, such as 5G MBS/5MBS (5G Multicast-Broadcast Services) for MCX services in high-density environments, 5G NR sidelink for off-network communications, VMRs (Vehicle-Mounted Relays), MWAB (Mobile gNB With Wireless Access Backhauling), satellite NTN (Non-Terrestrial Network) integration, and support for lower 5G NR bandwidths in dedicated frequency bands for PPDR, utilities, and railways.

SNS Telecom & IT projects that global investments in mission-critical 3GPP networks and associated applications reached $5.4 billion in 2025. Driven by public safety broadband, defense communications, smart grid modernization, FRMCS, and IIoT initiatives, the market is expected to grow at a CAGR of approximately 19% over the next three years, eventually accounting for more than $9.2 billion by the end of 2028. Looking ahead to 2030, the industry will be underpinned by operational deployments ranging from sub-1 GHz wide area networks for national-scale MCX services, utility communications, and GSM-R replacement to systems operating in mid-band spectrum such as Band n101 (1.9 GHz) and Band n79 (4.4-5 GHz), as well as mmWave (Millimeter Wave) frequencies for specialized applications.
