  • 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

  • The past and present of the ad hoc network of emergency communication

    2020-05-27

    The advantages of ad hoc network communication are: fast, low-cost networking, high resistance to self-healing, large bandwidth, high-speed mobile communication, ultra-long-distance communication and other advantages.1. ConceptAd hoc network is a combination of mobile communication and computer netw Read More

  • What is Wireless Ad-Hoc Network?

    2020-05-20

    Introduction to MESHMesh wireless ad hoc network system is a mobile broadband multimedia communication system designed with a brand new "wireless mesh network" concept.
