  • Why do we need a dedicated network?

    1. In terms of network purpose, a carrier network provides internet services to citizens for profit; therefore, operators only pay attention to downlink data and valuable area coverage. Public safety, meanwhile, usually requires a full-coverage nationwide network with more uplink data(e.g., video surveillance).
    2. In some cases, the carrier network may be shut down for security purpose(e.g., criminals might remotely control a bomb via s public carrier network).
    3. In big events, the carrier network can become congested and cannot guarantee quality of Service(QoS).
  • How can we balance broadband and narrowband investment?

    1. Broadband is the trend. It is no longer economical to invest in narrowband
    2. Considering network capacity and maintenance cost, the overall cost of broadband is equivalent to narrowband
    3. Gradually divert narrowband budget to broadband deployment
    4. Network deployment strategy: First, deploy continuous broadband coverage in high-benefit areas according to population density, crime rate, and security requirements.
  • What is the benefit of the emmergency command system if a dedicated spectrum is not available?

    1. Cooperate with the operater and use the carrier network for non-MC(mission-critical) service
    2. Use POC(PTT over cellular) for non-MC communication
    3. Small and light, three-proof terminal for officer and supervisor. Mobile policing apps facilitate official business and law enforcement.
    4. Integrate POC and narrowband trunking and fixed and mobile video through portable emmergency command system. In the unified dispatching center, open up multi-services such as voice, video, and GIS.
  • Is that possible to get more 50km transmit distance?

    Yes. It is possible. Our model FIM-2450 support 50km distance for video and Bi-directional serial data.
  • Can all your system support bi-directional data?

    Yes. All our UAVs video transmission model supports full duplex serial data. All of them have serial port. Their baud rate is up to be 115200bps(adjustable)
  • What brand of fly controller are your system compatible with?

    We don’t test all the brand fly controller on the market. Pixhawk is the most popular we use. The models our clients always use are APM, Pixhawk 2.1, Pixhack V3, Pixhawk 2 & Pixhawk4.
  • Does your system serial port support RS232?

    The serial ports support RS232 ±13V(-13V to +13V), and TTL (0~3.3V). It doesn’t support 5V voltage.
  • Do your system transmit also Mavlink telemetry info as flight info near the video?

    We are sure that the transmitter supports MAVLINK
    Regarding to the Telemetry, if your telemetry uses standard serial port meeting the following two requirements, then the telemetry is no problem for our transmitter.
       * baud rate equals to or less than 115200
       * supports 8N1 data format (8 data bits, no parity, and 1 Stop bit)
  • what is the latency?

    The latency is less than 50ms with our own Encoding & Decoding technology.
    Short delay is our system’s key feature. You can check the delay testing video in the website.
  • Does the video is full HD?

    Yes. The video transmission is full HD.
