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.

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.

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.

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.

IFLY Defensor System rapidly create MANET as an optimal solution for troops in a big area such as remote mountins, desert or dense jungles where GSM LTE coverage is 0 and no any fixed infrastructure.

(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
