Kundförfrågan
Vi är lösningsleverantör co. till polis och brottsbekämpande myndigheter i Pakistan. För närvarande behöver en av våra kunder Mobilt kommando- och kontrollcenter
1). De vill ansluta 4 HD PTZ-kameror och 2 handhållna HD-filmkameror med fordonets trådlösa nätverk för live-täckning och inspelning.
2). 1 Drone HD Camera också ville de ansluta till fordonet.
3). They also required same video stream to another ground station simultaneously.
4). Requirement of Hotline with command and control vehicle to ground station.
Kindly suggest the wireless equipment (Tx/Rx) which should have the range in between 20Km NLOS.
Behovsanalys
This customer needs a mobile command and control vehicle solution capable of transmitting multiple HD video feeds (from PTZ, handheld, and drone cameras) över a 20km non-line-of-sight (NLOS) avstånd. Dessutom, the system must support:
- Simultaneous transmission of live video to a secondary ground station.
- Two-way voice communication (hotline) between command vehicle and ground control.
- High stability and low latency for real-time operations.
Given these requirements, the best approach involves a combination of COFDM trådlös videoöverföring och IP Mesh networking radios.
Rekommenderad trådlös lösning
1. COFDM trådlöst videoöverföringssystem (20Km NLOS)
- Frekvensomfång: 280–300MHz or 1.4GHz band (for better NLOS penetration)
- Modulation: COFDM (QPSK/16QAM)
- Videoformat: H.265/H.264, 1080P60
- Latens: ≤250ms end-to-end
- Kryptering: AES-128/256 for secure law enforcement operation
- Gränssnitt: HDMI/SDI/AV input for PTZ and handheld cameras
- Räckvidd: Up to 20Km NLOS (with 10–15W power amplifier and high-gain antenna)
- Ansökan: Vehicle-mounted receiver station with DVR and 4-channel video recording
2. IP Mesh nätverksradio (för Drone + Marklänk)
- Supports IP video and data transmission between drone, fordon, and base station
- Self-forming, self-healing mesh allows simultaneous uplink and downlink
- Up to 80Mbps throughput
- Frekvens: 1.4GHz / 2.4GHz / 5.8GHz configurable
- Supports RC control and video in one link
- Extended range up to 20Km using high-gain directional antennas
3. Hotline kommunikationslänk
- Integrerad VOIP over IP Mesh eller dedicated narrowband digital radio (UHF/VHF) for hotline
- Allows real-time command communication between field team and command vehicle

FAQ
Q1: Vad är den största fördelen med att använda COFDM för denna applikation?
A1: COFDM offers robust NLOS performance and stable video transmission even in urban or moving environments.
Q2: Kan samma videoflöde ses på flera platser?
A2: Ja. The COFDM receiver can be connected to a rebroadcast link or IP Mesh network to send streams to multiple ground stations simultaneously.
Q3: Vilket frekvensområde rekommenderas för 20Km NLOS-drift?
A3: 280–300MHz or 1.4GHz bands are ideal due to their superior penetration and lower signal loss.
Q4: Kan röstkommunikation integreras i samma system?
A4: Ja, using IP-based voice (VOIP) or digital UHF radios as a hotline between the command center and ground station.
F5: Är systemet lämpligt för både stillastående och rörliga fordon?
A5: Absolut. COFDM technology is designed for mobile use, ensuring reliable links even while in motion.
