Solar Powered long range Base Stations

Model: Defensor-BL8

Defensor-BL8 is an Ad-hoc networking repeater that adopts the wireless interconnection and simulcast technology for providing log-term, stable, and large-scale wireless communication coverage. It eliminates the wiring problems between base stations in Tetra or DMR system and greatly reduces maintenance costs.

Defensor-BL8 is a solar powered base station integrated with battery and solar pannels. Power input supports AC220V, DC48V, DC12 V battery power supply and built-in 30 Amp battery option. One-click operation design doesnt need debugging before installation.

Max 40watts RF Power for ultra large area coverage. It can be installed in a place for permanent use or for emergency network building.

Product Description


➢Fast Deployment

Push-to-start for emergency. Creating and joining networks to deploy the communication system on power up.  

➢Multiple Power Supply Methods

Equipped with solar power system and built-in large capacity battery make it suitable for outdoor long time non-stop working.

➢Wireless Mobile Ad Hoc Networking

Establish a dual-channel self-reliant outdoor communication network in the harshest environment without infrastructure such as IP/Ethernet/power supply, via Ad Hoc communication technology.

➢Advanced Single Frequency Wireless ad hoc Network Technology

Defensor-BL8 uses IFLY's self-developed automatic addressing technology.  It doesn't relay on any wired link resources, 4G public network or satellite.

➢High Spectrum Efficiency

Based on TDMA technology, one frequency can be used to make calls and route voice at the same time, greatly saving frequency resources.

➢Remote Wireless Management

Defensor-BL8 is equipped with a management interface, which allow users to remotely manage all base station parameters in the same network and master the dynamics of the entire network.

➢IP67 Protection Level

IFLY Defensor-BL8 water and dust proof rating is up to IP67, which ensures outstanding performance even under harsh environments.
