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

demand analysis Forest fire is the most dangerous enemy of forest and the most terrible disaster of forestry. It will bring devastating consequences to forest. Moreover, the timing of forest fires is ever-changing, and firefighters are participating in forest firefighting, and the dangers faced a
IFLY provides a complete emergency solution for tactical operation in emergency events including ad hoc network equipment, portable command center, and dispatch software.
Demand analysisThe climate in spring is dry, and it is the high season for forest fires. Forest fires often occur in remote areas with trees and complex terrain, and it is difficult for conventional 4G networks to effectively cover them. Therefore, when a fire occurs, the problem of poor communicat
1. Introduction of MESH ad hoc network and its main technologiesMESH ad hoc network is a new type of wireless network that is completely different from traditional wireless networks. It is a technology that dynamically establishes new links to connect with other nodes. It has the advantages of self-
The pioneer of wireless ad hoc network technology-AdHoc network first appeared in the 1970s, mainly used for military communications. AdHoc network is a special wireless communication network, which can be quickly and automatically networked without relying on any pre-built network facilities, and h
In an emergency situation, communication is critical to the safety of first-aid personnel and the effective execution of emergency plans. However, in an emergency, the communication facilities are likely to be damaged:1. Extreme weather, such as the 2015 New Zealand Hunter District flood, may have a
With the continuous development of the hotel format, the hotel management also puts forward new requirements for communication within the hotel, requiring no blind spots, no interference, and clear voice. The hotel's welcome, reception, rooms, catering, security, and logistics can all Communicate an
After the Liangshan forest fire, the Sichuan Fire Rescue Corps immediately started the emergency communication cross-region linkage guarantee mechanism, flexibly applied the four dispatch modes of nearby, orchestration, laddering, and precision.
