Solar Powered long range MANET Radio Base Stations

Model: Defensor-BL8

IFLY Solar Powered base station is a Rapid Deployable Critical Mission Radio Communication solution has been specially designed for first-responder emergency and security services. When networks are down, or you're beyond cellular coverage, It instantly offers stable communication network to users.

Base on Ad Hoc network technology, Defensor-BL8 is capable to create a multi-hop network as soon as it is power on, in which every node connects with each other automatically and wirelessly by a single frequency.

It can be used for both temporary and permanent application. The big power solar pannels supports 24h continuous working.

Product Description


➢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
