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.
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.
This is practical test report of 10watts IP MESH. This testig was held in 31st May 2019. It is aimed to prove the 10watts IP MESH link modules ability and data rate for 130km-150km. According to the curvature of the earth and the Fresnel radius, we chose 3 test sites for 130km, 140km and 150km.
Today's public safety, security forces and emergency rescue demands advanced technologies that quickly bringing order to chaos with rapidly changing mission needs. When special events happend, first responders must be able to communicate during an emergency, reliably and without any security threats. That's why IFLY focuse on developing a strong anti-damage, secure and reliable tactical communications solutions. IFLY MANET communication radios deliver a resilient communication network that connects all devices—handheld, manpack repeater, solar powered base stations and command dispatcher platform. Rugged, compact and lightweight, our wirless Ad-hoc network system is engineered for today's disaster rescue site. They are also built on simulcast technologies, which are battle-tested and customer-proven for mission-critical communications.
IFLY Solar Powered VHF Radio Repeater(Defensor-BL8) merge MANET Technology with Radio. It solves many problems that today's wireless radio repeaters face. IFLY Defensor-BL8 is a industrial grade and portable solar powered repeater for VHF land mobile, VHF Marine & Aviation and remote mountain-top sites for covering a self-healing, mobile and flexible network. It wireless connects individual radio units and other IFLY bodyworn radio repeaters through a mobile ad-hoc network (MANET)based mesh topology to relay tactical clear audio and GPS data in an emergency disaster rescue or special event.
In remote areas such as big mountains and old-growth forest, the communication facilities are very poor. In order to minimize the loss of forest fires and keep fire fighters safe, Inner Mongolia Forestry Bureau has chosen a Mobile Ad-hoc Networking radio system by IFLY Solutions to build a monitoring and communication network for instant secure voice and data communications in Daxinganling forest region.
IFLY Assists Fire Service Successful in Exercise with Mobile ad-hoc networks Radio system. It's absolutely essential to use good and reliable communications equipment in rescue work as life or death can be decided in seconds. IFLY MANET Tactical radio is a critical communication tool to ensure effective fireground command and control, for personnel accountability, and to improve firefighter safety when operating within buildings during a fire or other emergency.
For missions requiring reliable, long-range communications equipment, IFLY has developed the Defensor-BM3. It is a VHF tactical manpack radio. It is designed to meet the demanding security requirements of emergency communication worldwide. It builds a safe and stable emergency long range communication network without any other infrastructure, helps commanders to take full control of the on-site situation timely.
From pre-planning to in-action commanding, SWAT officers rely on communication for safety and effectiveness. IFLY tactical LTE mission-critical communications and tactical radios for airborne, vehicular, manpack and handheld applications deliver unprecedented Situational Awareness through high-speed voice, data and Full-Motion Video. Call takers are allowed to both clearly hear the incident reporter and see the emergency to determine the on-site conditions.
IFLY IP Mesh Solutions is sepcial designed for nonline-of-sight tele-robotics missions in harsh urban environments and remote locations, and it will equips your teams with reliable bi-directional UGV communication for highspeed data and high-resolution video transfers in unpredictable environments.
(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
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
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
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
(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
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.
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.
IFLY Defensor system integrated the digital simulcast technology with ad-hoc network, which supply clear audio, IFLY Defensor system integrated the digital simulcast technology with ad-hoc network, which enables the system to extend coverage any time, any where.
