LFS169

TRANSCEIVER FOR DIGITAL AND ANALOG SIGNALS

The LFS169 transceiver is used for the wireless bi-directional transmission of digital and analog signals over great distances. The unit operates in the License-free frequency area of 169MHz and has a range of over 20km.

The LFS169 transceiver is used for the wireless bi-directional transmission of digital and analog signals over great distances. The unit operates in the License-free frequency area of 169MHz and has a range of over 20km.

By using a pair of the devices, a dependable connection between two station can be established. An autonomous signal transmission network can be created by adding more units, independent from providers and without cost.
Bi-directional operation, paired with 128bit AES cryptographic security and clear channel seeking, afford very high reliability of communication

The units can create network topologies such as:
- Point-to-point
- One point to many
- Many points to one
- Communication of two or more points via a repeater

They are commonly used in:
- Industry
- Water management
- WireΑless measurement and alarm transmission
- Production plant monitoring a.s.o.
