  • Key Technology of Wireless Ad Hoc Network

    2021-03-17

    Stream voice and data via an 'infrastructureless' network Infrastructure-based radio communication systems such as DMR, TETRA, P25 etc, which rely on cellular, fiber cable, IP connectivity or WiFi technology to deliver voice and data to the users. IFLY Wireless Mesh Networking (also called MANET, or Mobile Ad hoc Networking) communciation radio systems is the system that removing those infrastructure and adding mobility without any affecting the user’s high quality of service. A MANET critical communication radio system is a group of mobile (or temporarily stationary) devices which provide stream voice and data between handset radios utilizing the portable base station as relays to avoid the need for infrastructure.

  • Critical Technologies and Applications of Wireless Ad-hoc Network

    2021-03-10

    IFLY R&D team developed a new Radio based on MANET Technology to replace traditional DMR, POC, TETRA system. This radio device would connect individual unit members through a mobile ad-hoc network (MANET)based mesh topology to relay voice and GPS data information in a secure and robust manner while retaining the mobility needed for dismounted soldier operations. This paper describes the concept, features of the Ad hoc network in details. Read More

  • Characteristics of wireless ad hoc network

    2020-07-09

    (1) Network autonomyCompared with the conventional communication network, the wireless ad hoc network has the biggest difference that it can not need the existing information infrastructure at any time and any place. This is also a form of personal communication.(2) Dynamic topologyNodes have arbitr Read More

  • Technical characteristics and application of conventional co-channel simulcast wireless communication system

    2020-07-01

    Conventional co-channel simulcast system is to set up multiple relay stations in a region, so that each relay station forms a link interconnection and keeps working at the same frequency, thereby achieving effective coverage of wireless signals in a region and ensuring that the radio terminal is in Read More

  • Application of the same frequency simulcast technology in different industries

    2020-06-24

    The same frequency simulcast technology solves the problem of communication blind spots and excessive dead zones caused by same frequency interference in wireless communication, and truly realizes seamless coverage of signals and rapid expansion of wireless communication applications.1The problem of Read More

  • Simultaneous broadcasting on the same frequency encountered unprecedented challenges

    2020-06-17

    Inherent shortcomings of co-channel simulcast  1. Co-channel simulcast cannot completely eliminate co-channel interferenceBecause the same-frequency simulcast system adopts the same-frequency technology, in order to obtain clear voice quality in the overlapping coverage area, the system must achieve Read More

  • Advantages of Simultaneous broadcasting

    2020-06-10

    (1) Flexible networking, each base station's turntable usually works on its own channel. If there are major tasks that require multiple base stations to be networked, each simulcast base station can be set to one or more simulcast groups through the network management center. Forming a simulcast net Read More

  • Top 7 Reasons for IFLY Military Tactical Radio

    2020-06-05

    When disaster or special events occur, emergency people enter an area such as remote mountain, desert or jungles where the GSM LTE coverage is near to 0 and no any fixed infrastructure. IFLY porable tactical raido could ensure a clear audio communication to help you focus on mission. Read More

  • What is a multicast radio system?

    2020-06-03

    Simulcast (simultaneous broadcasting) means multiple base stations transmitting the same voice (or data) signal on the same frequency at the same time. This means that every frequency pair – probably your existing channels – can each provide greatly extended coverage across a very wide area. The secret to Simulcast is high-stability transmitters and signal timing, structured and implemented by coverage experts to negate potential interference. Read More
