Product Description
Highlights
➢Stream voice and data via an “infrastructureless” network
Defensor-BL8 is designed on wireless ad hoc multi-hop network. Each base station works as a router to forward data packets to each other. The whole system doesnt rely on any fixed infrastructure, such as cellular coverage, fiber cable, IP connectivity, power cable, etc.
➢Reduce frequency license costs
1-frequency carrier supports 3ch/2ch/1ch simultaneously. No need to apply multiple frequency certificate from Telecom Organization for more channels.
➢Full duplex communication: free the hands of first-responders
Half-duplex and full duplex mixed networking. Press PTT or speak directly via transparent earpiece for duplex voice communication.
➢High flexibility for extended network
Any IFLY adhoc base station can join in or leave the network any time. If the area requiring network coverage is very large, several IFLY ad hoc base station can be immediately powered on and join in and linked together to create a large communication network.
➢Robust and secure
Can be deployed in even the harshest conditions without any infrastructure.
➢Long range communication range
wireless ad hoc network is a multi-hop networkis a multi-hop network. One hop is about 20-60km
